Comprehensible, interactive experiments: practice and theory in the MINT study

Be-greifenThe project is funded by the Federal Ministry of Education and Research (BMBF). Combine tangible, manipulatable objects (“tangibles”) with advanced technologies (“Augmented Reality”) to develop new, intuitive user interfaces. Through interactive experiments, it will be possible to actively support the learning process during the MINT study and to provide the learner with more theoretical information about physics.

In the project interfaces of Smartphones, Smartwatches or Smartglasses are used. For example, a data gadget that allows you to view content through a combination of subtle head movements, eyebrows, and voice commands, and view them on a display attached above the eye. Through this casual information processing, the students are not distracted in the execution of the experiment and can access the objects and manipulate them.

A research project developed as a preliminary study demonstrates the developments. For this purpose, scientists at the DFKI and at the Technical University Kaiserslautern have developed an app that supports students and students in the determination of the relationship between the fill level of a glass and the height of the sound. The gPhysics application captures the amount of water, measures the sound frequency and transfers the results into a diagram. The app can be operated only by gestures of the head and without manual interaction. In gPhysics, the water quantity is recorded with a camera and the value determined is corrected by means of head gestures or voice commands, if required. The microphone of the Google Glass measures the sound frequency. Both information is displayed in a graph that is continuously updated on the display of Google Glass. In this way, the learners can follow the frequency curve in relation to the water level directly when filling the glass. Since the generation of the curve is comparatively fast, the learners have the opportunity to test different hypotheses directly during the interaction process by varying various parameters of the experiment.

In the project, further experiments on the physical basis of mechanics and thermodynamics are constructed. In addition, the consortium develops technologies that enable learners to discuss video and sensor recordings as well as analyze their experiments in a cloud and to exchange ideas with fellow students or to compare results.

The DFKI is a co-ordinator of five other partners in research and practice: the Technical University of Kaiserslautern, studio klv GmbH & Co. KG Berlin, University of Stuttgart, Con Partners GmbH from Bremen and Embedded Systems Academy GmbH from Barsinghausen.

PROWILAN

Professional Wireless Industrial LAN

Due to the rising requirements of the industry for a flexible and cost-efficient production, secure and robust wireless solutions are steadily gaining much interest. The BMBF project “Professional Wireless Industrial LAN – proWiLAN” comprises a number of experts from a consortium of eight German organizations developing the next generation of wireless radio technology, which will meet the rapidly growing requirements of the future industrial applications.

The aim of the project is to improve robustness, bandwidth and latency of wireless solutions so that even sophisticated or safety-critical applications such as augmented reality or radio-based emergency stop button can be efficiently and user-friendly supported. The common wireless technologies allow stable execution of cooperative Augmented Reality applications only to a limited extent. Besides, in inaccessible environments where assembly and maintenance work should be performed, present-day wireless technologies cannot satisfy the growing requirements.

Necessary and planned innovations include, among others, a multi-band-capable radio interface, which is not sensitive to interferences in each single band and thus is always immediately available. This makes very fast response times of applications possible. It is important to be able to ensure short response times of the systems in order to e.g. achieve the guaranteed shut down time of a machine in case of an emergency stop. Another key innovation of proWiLAN is the integration of a powerful 60-GHz module, which brings a significant increase of transmission data rates. Furthermore, a localization method for industrial environments should be integrated, so that mobile devices should be capable of determining their location and orientation in space. In order to get a high customer acceptance, novel Plug & Trust process developed in proWiLAN, which allows a quick and easy commissioning, retrofitting and security, is of key importance.

proWiLAN is funded by the research program ICT 2020 — Research for Innovations by the Federal Ministry of Education and Research (BMBF) with a total of 4.6 million euro. The project started in February 2015 and runs until the beginning of 2018. In addition to the DFKI as project coordinator, the consortium includes ABB AG, IHP – Leibniz Institute for Innovative Microelectronics, IMST GmbH, NXP Semiconductors Germany GmbH, Bosch Rexroth AG, Robert Bosch GmbH and the Technical University Dresden.

The virgin stone marble has been used as preferred material for representative buildings and sculptures. Yet, due to its chemical composition and its porosity marble is prone to natural deterioration in outdoor environments, with an accelerating rate since the beginning of industrialization, mainly due to increasing pollution. A basic requirement for a successful restoration and conservation is a regularly repeated assessment of the current object condition and knowledge about prior restoration actions. Ideally the assessment is non-destructive. This requirement is fulfilled for both the optical digitization of objects shape and appearance, and the ultrasound examination used to acquire properties with respect to material quality.

Goal of the joint research project Marmorbild of the University Kaiserslautern, the Fraunhofer Institute (IBMT), and the Georg-August-University Göttingen is the validation of modern ultrasound technologies and digital reconstruction methods with respect to non-destructive testing of facades, constructions and sculptures built from marble. The proof of concept has been provided with prior research.

The planned portable assessment system holds a high potential for innovation. In the future, more objects can be examined cost-effectively in short time periods. Damage can be identified at an early stage allowing for a target-oriented investment of efforts and financial resources.

Design and application of an ultra-compact, energy-efficient and reconfigurable camera matrix for spatial analysis

Within the DAKARA project an ultra-compact, energy-efficient and reconfigurable camera matrix is developed. In addition to standard color images, it provides accurate depth information in real-time, forming the basis for various applications in the automotive (autonomous driving), production (Industry 4.0) and many more.

 

Real-time depth image calculations with camera matrix

The ultra-compact camera matrix, which is composed of 4x4 single cameras, not only functions as a camera for color images but also as a provider for depth information
The ultra-compact camera matrix, which is composed of 4x4 single cameras, not only functions as a camera for color images but also as a provider for depth information

The ultra-compact camera matrix is composed of 4×4 single cameras on a wafer and is equipped with a wafer-level optics, resulting in an extremely compact design not bigger than a cent-coin. This is made possible by the innovative camera technology of the AMS Sensors Germany GmbH.

The configuration as a camera matrix captures the scene from sixteen slightly displaced perspectives and thus allows the scene geometry (a depth image) to be calculated from these by means of the light field principle. Because such calculations are very high-intensity, close integration of the camera matrix with an efficient, embedded processor is required to enable real-time applications. The depth image calculations, which are researched and developed by DFKI (Department Augmented Vision), can be carried out in real-time in the electronic functional level of the camera system in a manner that is resource-conserving and real-time. Potential applications benefit significantly from the fact that the depth information is made available to them in addition to the color information without further calculations on the user side. Thanks to the ultra-compact design, it is possible to integrate the new camera into very small and / or filigree components and use it as a non-contact sensor. The structure of the camera matrix is reconfigurable so that a more specific layout can be used depending on the application. In addition, the depth image computation can also be reconfigured and thus respond to certain requirements for the depth information.

Ultra-compact, reconfigurable, low energy consumption
The innovation of the DAKARA project represents the overall system that provides both color and depth images. Similar systems, which are also found in the product application, are generally active systems that emit light and thus calculate the depth. Major disadvantages of such systems are large designs, high energy consumption and high costs. There are passive systems that have much lower energy consumption, but are still in the research stage and generally have large designs and low image rates.

For the first time, DAKARA offers a passive camera, which convinces with an ultra-compact design, high image rates, reconfigurable properties and low energy consumption, leaving the research stage and entering the market with well-known users from different domains.

 

Three-Dimensional Geometry for Automotive and Industry

In order to demonstrate the power and innovative power of the DAKARA concept, the new camera is used in two different application scenarios. These include an intelligent rear-view camera in the automotive field and the workplace assistant in manual production.

The planned intelligent rear-view camera of the partner ADASENS Automotive GmbH is capable of interpreting the rear vehicle environment spatially, metrically and semantically compared to currently used systems consisting of ultrasonic sensors and a mono color camera. As a result, even finer structures such as curbsides or poles can be recognized and taken into account during automated parking operations. In addition, the system is able to detect people semantically and to trigger warning signals in the event of an emergency. The DAKARA camera provides a significant contribution to increasing the safety of autonomous or semi-automated driving.

A manual assembly process at the Bosch Rexroth AG and DFKI (Department Innovative Factory Systems) is shown in the case of the workplace assistant. The aim is to support and assure the operator of his tasks. For this purpose, the new camera matrix is fixed over the workplace and both objects and hands are detected spatially and in time by the algorithms of the partner CanControls GmbH. A particular challenge is that objects such as tools or workpieces that are held in the hand are very difficult to separate from these. This separation is made possible by the additional provision of depth information by the DAKARA camera. In this scenario, a gripping path analysis, a removal and level control, the interaction with a dialog system and the tool position detection are implemented. The camera is designed to replace a large number of sensors, which are currently being used in various manual production systems by the project partner Bosch Rexroth, thus achieving a new quality and cost level.

In the next three years, the new camera matrix will be designed, developed and extensively tested in the mentioned scenarios. A first prototype will be realized by late summer 2018. The project “DAKARA” is funded by the Federal Ministry of Education and Research (BMBF) within the framework of the “Photonics Research Germany – Digital Optics” program. The project volume totals 3.8 million euros; almost half of it being provided by the industry partners involved.

Simulated reduction of glareThe research project LiSA is a broad-based joint project in the area of façade, lighting and control technology. The aim is enabling the most energy-efficient operation of office and administrative buildings taking into account user satisfaction. Through exemplary system integration the understanding of the interaction of individual components and the necessity of system solutions are promoted.

At component level technologies are being developed which enable the efficient use of daylight, provide energy-saving lighting with artificial light, and reduce cooling load during summer by means of shading. At the level of sensor technology, a cost-effective sensor is developed, which measures the light conditions as well as heat inputs to the room by solar radiation. A model-predictive control approach optimizes the operation of the components, which can be managed and controlled via wireless communication paths.

With the implementation of the project in a Living Lab Smart Office Space, which is subject to detailed monitoring and in which people use the space according to the actual purpose, it is ensured that the developments are continuously empirically validated and that the results are perceived by users as added value. The people working in the Living Lab have the opportunity to interact with the technology and are thus an essential part of the investigations.

The objective of DYNAMICS is to develop a new methodology for 4D reconstruction of real world scenes with a small number of cameras, as well as to learn statistical models from the captured data sets. A 4D reconstruction refers to a sequence of accurate 3D reconstructions (including geometry, topology and surface properties) of a dynamic (evolving in time) real-world scene. We aim to build a robust lightweight capture system that can be easily installed and used (e.g. in the living room of a house, in outdoor environments, and broadly under various spatial and temporal constraints).

We are developing a novel interactive software system for motion estimation capitalizing on our experience from the predecessor project DENSITY and exploring new directions (new hardware and machine learning methods).

Specifically, the project DYNAMICS can be subdivided into several work packages according to the target scenarios and concerned areas of computer vision:

1) Software for an interactive monocular 4D reconstruction of non-rigid scenes. The main components are modules dealing with non-rigid structure from motion
(NRSfM) pipeline and non-rigid registration. Underlying technology will allow to reconstruct non-rigidly deforming scenes with a minimal number of assumptions from a single RGB camera.
Target scenarios include endoscopy, capture of facial expressions, small motion and post-factum reconstructions.

2) Software for robust 4D reconstruction from multiple views incorporating optical flow and scene flow with additional assumptions. We plan to assemble a capture studio with five Emergent HT-4000C high-speed cameras (a multi-view setting). Here, we aim at the highest precision and richness of detail in the reconstructions.

3) 3D shape templates with attributes derived from real data using deep learning techniques. The main objective of this work package is to provide statistical models as a prior knowledge in order to increase the robustness and accuracy of reconstructions. Furthermore, the shape templates will allow for more accurate reconstructions of articulated motion (e.g. skeleton poses) from uncalibrated
multi-view settings.

DYNAMICS is a BMBF project with an emphasis on development of core technologies applicable in other ongoing and forthcoming projects in the Augmented Vision Lab.

            The aim of this research project is to create an open platform and associated digital infrastructure in the form of interfaces and architectures that allow market participants to achieve simple, secure and fair participation at different levels of value creation. This platform will be designed for the recording, analysis and aggregation of data acquired from everyday used sensors (Smart Objects), as well as the conversion of these data into digital services (Smart Services), both technically and with regard to the underlying business and business model. Furthermore, for an initial technical product area, sports shoes will be considered, the possibility is exerted to extend these to cyberphysical systems which go beyond the existing possibilities of data collection (pure sensors). This is to create a broadly communicable demonstrator object that can bring the possibilities of smart services and intelligent digitization to the general public. In addition, the technical prerequisites as well as suitable business models and processes are created in order to collect the data under strict observance of the legal framework as well as the consumer and data protection for the optimization of product development, production and logistics chains. Here, too, an open structure will allow market participants to work with these data at different levels of added value.

Capture2

During the project period, national standardization and work for the necessary internationalization can be started in parallel, and all preparatory work should be done by the end of the project. Standardization is the foundation for trust to motivate companies to participate in the platform. On the basis of the defined standards a certification can take place. This is necessary to ensure data exchange (encryption) and the security of the networks (against cybercrime). This also includes clarifying questions about the right to data in the cloud.

Contact person: Stephan Krauß

The goal of the SwarmTrack project is the research and development of a novel method for accurate automatic tracking of objects moving in groups.

A common problem in object tracking are occlusions, where moving objects or static parts of the scene obstruct the view on the target objects. This may lead to tracking loss or wrong assignment of identity labels. Another important issue is confusion where nearby objects have a similar or identical appearance. This may lead to errors in the identity assignment, where labels are switched between objects.

SwarmTrack investigates possibilities for exploiting the group structure in the spatial and temporal domain to derive clues and constraints for correct identity assignment after occlusions and in the presence of similar objects. Such clues include the spatial arrangement of the tracked objects and its changes over time as well as motion continuity and coherency constraints. Furthermore, SwarmTrack investigates methods for the automatic creation of coherent groups as well as updating them, when objects leave the group or new objects join.

The resulting multi-target tracking approach has applications in traffic monitoring and analysis as well as other fields where objects move coherently in groups.

ANNA – Artificial Neural Network Analyzer

A Framework for the Automatic Inspection of TRUS Images

The project ANNA (Artificial Neural Network Analyzer) aims at the design of a framework to analyze ultrasound images by means of signal processing combined with methods from the field of artificial intelligence (neural networks, self-organizing maps, etc.). Although not obvious ultrasound images do contain information that cannot be recognized by the human visual system and that do provide information about the underlying tissue. On the other hand the human visual system recognizes virtual structures in ultrasound images that are not related at all to the underlying tissue. Especially interesting in this regard is the fact that the careful combination several texture descriptor based filters is suited for an analysis by artificial neural networks and that suspicious regions can be marked reliably. The specific aim of the framework is to automatically analyze conventional rectal ultrasound (TRUS) images of the prostate in order to detect suspicious regions that are likely to relate to a primary cancer focus. These regions are marked for a subsequent biopsy procedure. The advantages of such an analysis are the significantly reduced number of biopsies compared to a random or systematic biopsy procedure to detect a primary cancer and the significantly enhanced success rate to extract primary cancer tissue with a single biopsy procedure. On one hand this results in a faster and more reliable diagnosis with significantly decreased intra-examiner variability, on the other hand the discomfort of the patient due to multiple biopsy sessions is dramatically reduced.
