Abstract

With the proportion of artificial intelligence becoming more important, binocular vision technology is more widely used in the field of machine vision. An important step that must be experienced is binocular camera calibration. The accuracy of binocular calibration will also directly affect the accuracy of subsequent work. In view of the disadvantages of low accuracy and poor robustness, Halcon calibration uses binocular camera calibration and stereo correction. This method fully considers the influence of camera distortion on calibration, and determines the conversion relationship between each coordinate system. The internal and external parameters of the camera were obtained and validated by image-stereo correction experiments. The results show that the calibration method is highly accurate and can be widely used in the binocular vision field.
