Abstract
The present disclosure provides a method for calibrating a binocular camera, including: Sof extracting feature points from an image set 1 and an image set 2 taken at two points separated from each other by a predetermined distance; Sof fitting Gaussian distribution parameters of each feature point, and extracting a desired value as a theoretical disparity; Sof selecting a common feature point, and calculating the predetermined quantity of frames at a first theoretical distance and the predetermined quantity of frames at a second theoretical distance; Sof performing Gaussian fitting on a difference between the theoretical distances of the common feature point, and extracting a variance as an evaluation index; Sof determining whether the evaluation index is smaller than a threshold, if yes, terminating the calibration, and otherwise, proceeding to S; and Sof adjusting posture parameters of the binocular camera, and returning to S
