Abstract

We have been investigating depth estimation techniques using variant of depth of field (DOF) by tilted optics imaging. These techniques can be applied for robotic and automation tasks, because it needs extremely fewer multiple focus images for depth estimation than the conventional passive methods. Hence, our method gets rid of the bottleneck of passive methods with a single camera; the motion speed of optical mechanics is very slower than that of image processing parts. Therefore, it is suitable for the high speed depth estimation like real-time processing accomplished by hardware such as a smart image sensor or an FPGA.
