2D Camera Calibration Guide
Function
2D camera calibration establishes the mapping relationship between camera imaging and the actual space, thus improving the accuracy of image measurement and positioning. It is the foundation of the vision system for high-accuracy recognition and positioning.
2D camera calibration consists of the following two parts:
-
Distortion Calibration: used to correct distortions (lens distortions or perspective distortions) introduced into the camera lens, eliminating geometric distortions in the image, and restoring the image to its true geometric shape.
-
Hand-Eye Calibration: Hand-eye calibration is the calibration of extrinsic parameters used to establish the transformation relationship between the camera reference frame and the robot reference frame. It defines the transformation relationship between the pixel coordinates on the camera imaging plane and the poses in the robot reference frame, so that the robot can accurately pick based on the 2D image.
By performing distortion calibration and hand-eye calibration, you can effectively improve the accuracy and stability of the vision system in positioning, measurement, and guidance applications.
