Measuring Material Displacement on Steel Specimens During Strain Tests
(details) |
Deformation analysis of material surfaces is a crucial part of material testing and quality control. In this project a stereoscopic surface measurement system has been developed which allows to measure surface deformation during stress/strain tests over a wide range of fields of view. Stereo image pairs are acquired at specified time instances which makes it possible to synchronize the acquisition with the amount of stress applied. |

Vision Based Kinematic Calibration and Error Compensation of Articulated Robot Arms
(details) |
Development of a vision system for accurate calibration of the kinematic chain of an articulated robot arm. The absolute positioning error of articulated robot arms is typically by an order of ten higher than their repeatability error. Inaccurate blueprint kinematic models typically account for 90% of this discrepancy. In this work a calibration procedure is developed which calibrates the kinematic model of a robot arm using fixed stereo rig and a calibration target mounted on the robot hand. In a single calibration framework the following parameters are automatically determined:
The procedure is fully automatic and does not require expensive, precalibrated equipment. |

Vision Based Detection of Wrong-Way Drivers
(details) |
Vehicles driving the wrong way down a motorway represent a serious source of danger. In the year 2005 in Austria, 521 vehicles were counted driving in the wrong direction on motorways. 8 people died due to wrong-way driver accidents. Immediate detection of a vehicle driving in the wrong direction could help preventing serious accidents by warning the oncoming vehicles (via traffic telematic systems or radio announcements) and by alarming the police. To guarantee immediate detection, one would have to observe every access ramp and every place where a car could turn. Thus a low-cost monitoring system capable of detecting wrong-way drivers and forwarding an alarm to a central traffic control station is needed. Image based detection suffers from one main problem: In case a large vehicle (truck, bus etc.) throws a shadow to the opposite lane of a motorway, that shadow moves against the direction of traffic and may cause a false detection. With a monocular camera system (one single camera), this problem can only be eliminated by large computational costs. |

TRICam - Robust Object Detection and Tracking on an Embedded System
(details) |
Development of Computer Vision Algorithms for Robust Object Detection and Tracking on an Embedded DSP Platform. FREQUENTIS was working on an embedded platform called "TRICam". The platform is capable of acting as a high quality Motion-JPEG or MPEG4 Encoder or Decoder; furthermore, it can perform a set of selected image processing algorithms for object detection and tracking in real-time. The focus was mainly put on traffic monitoring, vehicle detection and tracking. The goal was to also deal with various algorithms for video surveillance in public places and public transport. |
