Description:
Many applications in Computer Vision require the automatic analysis and reconstruction of static and dynamic scenes. Therefore the automatic analysis of three-dimensional scenes is an area which is intensively investigated. Most approaches focus on the reconstruction of rigid geometry because the reconstruction of non-rigid geometry is far more challenging and requires that three-dimensional data is available at high frame-rates. Rigid scene analysis is for example used in autonomous navigation, for surveillance and for the conservation of cultural heritage. The analysis and reconstruction of non-rigid geometry on the other hand provides a lot more possibilities, not only for the above-mentioned applications. In the production of media content for television or cinema the analysis, recording and playback of full 3D content can be used to generate new views of real scenes or to replace real actors by animated artificial characters. The most important requirement for the analysis of dynamic content is the availability of reliable three-dimensional scene data. Mostly stereo methods have been used to compute the depth of scene points, but these methods are computationally expensive and do not provide sufficient quality in real-time. In recent years the so-called Time-of-Flight cameras have left the prototype stadium and are now capable to deliver dense depth information in real-time at reasonable quality and price. This thesis investigates the suitability of these cameras for the purpose of dynamic three-dimensional scene analysis. Before a Time-of-Flight camera can be used to analyze three-dimensional scenes it has to be calibrated internally and externally. Moreover, Time-of-Flight cameras suffer from systematic depth measurement errors due to their operation principle. This thesis proposes an approach to estimate all necessary parameters in one calibration step. In the following the reconstruction of rigid environments and objects is investigated and solutions for these tasks are presented. The reconstruction of ...
