Abstract
We have been investigating a multi-sensor system on which arbitrary viewpoint images can be synthesized by using image based rendering (IBR). The imaging system consists of randomly accessible smart image sensors and a field programmable gate array control circuit and generates real-time arbitrary viewpoint images. Although the system can generate more realistic images compared with the model-based rendering system, the generated images degrade if the depth information used for synthesis has errors. We have now created a method for estimating depth using the IBR imaging system. Various synthesized images are repeatedly compared with an actual image that is captured with a sensor. The depth information enables the generation of more realistic arbitrary viewpoint images.
