Effect of Baseline Distance and Corner Consistency on Binocular Visual Locating

Abstract

Taking baseline distance and corner consistency of checkerboard calibration board as objects and combining stereo matching algorithm, the influence of baseline distance and corner consistency on camera calibration and binocular vision locating error is analyzed through building binocular vision locating system. The results show that the calibration error decreases with the increase of angular consistency and baseline distance, and finally tends to be stable. Under the condition of the same baseline distance, the locating error decreases with the increase of angular consistency. The calibration plate with large angular consistency has better locating error stability. The research has practical value for the design of binocular vision locating system's baseline distance and angular consistency.
