Abstract

Multi-camera systems are being deployed in a variety of vehicles and mobile robots today. To eliminate the need for cost and labor intensive maintenance and calibration, continuous self-calibration is highly desirable. In this book we present such an approach for self-calibration of multi-Camera systems for vehicle surround sensing. In an extensive evaluation we assess our algorithm quantitatively using real-world data.

Abstract

Environment perception with cameras is an important requirement for many applications for autonomous vehicles and robots. This work presents a stereoscopic omnidirectional camera system for autonomous vehicles which resolves the problem of a limited field of view and provides a 360° panoramic view of the environment. We present a new projection model for these cameras and show that the camera setup overcomes major drawbacks of traditional perspective cameras in many applications.

Abstract

This work proposes novel approaches for object tracking in challenging scenarios like severe occlusion, deteriorated vision and long range multi-object reidenti?cation. All these solutions are only based on image sequence captured by a monocular camera and do not require additional sensors. Experiments on standard benchmarks demonstrate an improved state-of-the-art performance of these approaches. Since all the presented approaches are smartly designed, they can run at a real-time speed.

Abstract

In order to develop a driver assistance system for pedestrian protection, pedestrians in the environment of a truck are detected by radars and a camera and are tracked across distributed fields of view using a Joint Integrated Probabilistic Data Association filter. A robust approach for prediction of the system vehicles trajectory is presented. It serves the computation of a probabilistic collision risk based on reachable sets where different sources of uncertainty are taken into account.

Abstract

Thermal infrared deflectometry is based on the effect that rough surfaces, although having a dull appearance in the visual spectrum, exhibit a specular reflection in the thermal infrared spectrum and therefore enabling surface inspection with the method of deflectometry. This work covers the problems of generating the required thermal code patterns. The evaluation either adapts established methods from deflectometry, or new methods are introduced.

Abstract

The presented work introduces an accuracy analysis of normal vectors from binocular camera systems, which allows to model the surface orientation uncertainties by considering few parameters. The results of the accuracy analysis are used to design two methods for environment perception: a free space estimation for vehicles as well as the staircase detection for visually impaired persons.
