A camera calibration system includes a server, a camera communicatively coupled to the server, a drone communicatively coupled to the server, and an identification pattern coupled to the drone. The server controls the drone to fly in front of the camera at a calibration distance according to position and orientation information of the camera and position information and a distance setting rule of the drone, controls the camera to acquire at least one image of the identification pattern at each of the plurality of positions, and obtains parameters of the camera by performing calibration on the camera according to the acquired plurality of images. The drone flies in a number of positions at the calibration distance and flies in at least one plane.
