Abstract
Description
technical field
[0001] The present application belongs to the technical field of image processing, and in particular relates to a camera calibration method, device, electronic equipment and storage medium. Background technique
[0002] Camera calibration has important applications in many scenarios. For example, for vehicle, pedestrian, infrared temperature detection, etc., it is necessary to calibrate the internal and external parameters of the camera in advance, and the calibrated camera can calculate the world coordinates of the detected objects in the image. information, so the calibration of the camera plays a very important role in the accuracy of the whole system.
[0003] Camera calibration is divided into two parts: internal reference calibration and external reference calibration. The internal reference is used to determine the projection relationship of the camera from the three-dimensional space to the two-dimensional image, and the external reference is used to ...
