Study Of Depth Measurement Based On Integral Imaging

Taken depth information from Integral Imaging, the extraction process is simple and doesn't require camera calibration, and three-dimensional image reconstruction is becoming a hot area of research at home and abroad.A complete process of depth extraction includes the following parts:extraction of view image, image pre-processing, stereo matching, disparity map and depth extraction. This paper carried out the research centering at depth extraction from Integral Imaging.Firstly,we described the Integral Imaging technique and its development in detail; Analyzed and derived the calculation method of depth information extraction from Integral Image; Then focused on the research of disparity analysis between the view image pairs. In stereo matching, by analyzing imaging features of integral imaging, use corner-based feature two-way matching algorithm, and add Marr stereo matching constraints to obtain more the best match points, and then conduct a parallax analysis between view images. Finally, by the relationship between depth and parallax, it finds out depth information of target points.
