Abstract
We have proposed three-dimensional recovery methods using random camera rotations imitating involuntary eye movements of a human eyeball. Those methods are roughly classified into two types. One is a differential-type using temporal changes of image intensity, and is suitable for coarse textured images relative to the amplitude of the image motion. Another is an integral-type using image blur caused by the camera motions, and is proposed for fine textured images. In this study, we focus on the differential-type method. In this method, it is important that unsuited image pairs for the gradient equation should not be used for computing. We attempt to improve the accuracy by selecting suitable image pairs at each pixel and using only those to recover a depth map. Additionally, we evaluate the performance of the improved method by actually implementing the camera system which can capture images with performing small irregular rotations.
