Research on online measurement method of image target size based on binocular vision


  • H Chen



This article provided a detailed analysis and discussion on the key points that affect the calibration accuracy of binocular cameras. A planar calibration board based on solid dot marker guided matching was designed, and its superiority over traditional calibration boards through experiments were verified. At the same time, an improved camera calibration method based on two-step RANSAC algorithm was proposed, and the calibration flow of binocular camera was designed for the improved calibration method. This method solves the problem of difficult target size calibration in images and has broad application prospects in the fields of online measurement of image targets and small target image recognition.
