Calibration Experiences of Multiple RGB/Depth Visions for Capturing a Surgical Area

摘要

In the last year, we developed some multiple camera system to measure a surgical area and get several capturing results in our laboratory. In this paper, in order to evaluate the multiple camera system, we first check how to calibrate three RGB/Depth cameras based on many landmarks. Then, when a doctor uses a microscope for the microsurgery, he/she raises or lowers the camera. In this case, we evaluate depth changes at each pixel or the average of all pixels within depth image of each camera in distance. In the evaluation method, it is measure the depth values at five different distance. Through this evaluation, we study about the performance of our capturing system.
