• 論文抄録 / 内容記述: An active measurement, that senses the scene with a camera under controlled illumination, is one of the common techniques in computer vision field. Most of the conventional techniques rely on ideal light transport, or a response to the illumination of the scene. However, since an actual light transport depends on scene geometry and light behavior, undesired light transport such like inter-reflections and scattering could degrade the measurement. The goal of this thesis is to acquire desired light transport for further application such like to analyze the light behavior, to visualize the meaningful information, and to capture the appearance of objects in the real world, that are important tasks in the field of computer vision and computer graphics. To acquire the desired light transport, we focus on the light path from a light source to a sensor cell in the camera. In the conventional imaging, since the camera forms image by integrating all the light to sensor cells from various directions during exposure, the information of each path is lost. In order to acquire light transport before integration, we propose a selective path measurement. We control illumination and exposure to specify the path for the measurement. Our contribution also includes the proposal of the analysis and the application of the light transport.
