Abstract

The paper reviews the recent research progresses of vision measurement. The general methods of the depth detection used in the monocular stereo vision are compared with each other. As a result, a novel bifocal imaging measurement system based on the zoom method is proposed to solve the problem of the online 3D measurement. This system consists of a primary lens and a secondary one with the different focal length matching to meet the large-range and high-resolution imaging requirements without time delay and imaging errors, which has an important significance for the industry application.
