Analysis of depth estimation error for cylindrical stereo imaging
Conventional stereo imaging uses area CCDs for which depth perception error has been analyzed in our past research (Comput. Vision Image understand. 63 (3) (1996) 447). In this work we analyze the depth perception error for a stereo system that uses two rotating linear CCD cameras to create cylindrical stereo images. Theoretical analysis shows certain advantages to cylindrical stereo imaging over conventional methods. Initial experimental results are presented to validate the theoretical results. Unlike normal area CCDs, cylindrical images captured by rotating linear CCD cameras can produce very high-resolution images thereby substantially reducing the error in 3D estimation.
