説明
A real-time and wide-field-of-view image pickup system for coarse integral volumetric imaging (CIVI) is realized. This system is to apply CIVI display for live action videos generated by the real-time 3D reconstruction. By using multiple RGB-D cameras from different directions, a complete surface of the objects and a wide field of views can be shown in our CIVI displays. A prototype system is constructed and it works as follows. Firstly, image features and depth data are used for a fast and accurate calibration. Secondly, 3D point cloud data are obtained by each RGB-D camera and they are all converted into the same coordinate system. Thirdly, multiview images are constructed by perspective transformation from different viewpoints. Finally, the image for each viewpoint is divided depending on the depth of each pixel for a volumetric view. The experiments show a better result than using only one RGB-D camera and the whole system works on the real-time basis.
