Abstract

Active stereo is one of the means for estimating depth, which uses a camera and a projector. The projected patterns are classified into two groups: a time code or a space code. In recent years, a space-time hybrid code was investigated to fully utilize the advantages of both codes. With this method, one needs to separate the information from captured images, on which the information for both codes are coexisting and mixing. In this paper, we propose to use the color space to successfully construct and extract the information for the time/space codes.
