Abstract

The invention relates to the image processing technology, and discloses a binocular camera calibration method and device, and a readable storage medium, and the method comprises the steps: obtaining a first image sample and a second image sample of a to-be-calibrated object, obtaining the information of the first image sample based on a first camera of a binocular camera, and obtaining the information of the second image sample; wherein the second image sample information is acquired based on a second camera of the binocular camera; generating a feature initial sample set based on the first image sample and the second image sample; and inputting the feature initial sample set into a preset neural network model for calculation to obtain a calibration model of the to-be-calibrated object. The problem of low calibration precision of a binocular camera in the prior art can be solved.

Description

technical field [0001] The invention relates to image processing technology, in particular to a binocular camera calibration method, device and readable storage medium. Background technique [0002] The ideal camera model is a pinhole imaging model, but due to the influence of the convex lens of the camera during the processing and transportation stage, the model will undergo nonlinear distortion. Therefore, the method of using a linear imaging model to replace the actual imaging process of the camera is too simple, and the calibration accuracy cannot reach the level of industrial application, so it is difficult to apply in actual production. [0003] For binocular cameras, not only the calibration parameters of each camera need to be considered, but also the transformation matrix between the two cameras. Therefore, the existing binocular cameras have many calculation parameters in the calibration process, and the calculation involved The larger the amount, the lower the ca...
