System for improving positioning precision of pan-tilt camera and control method therefor

The invention relates to the technical field of computer vision in a remote monitoring system. The invention relates to a control method for improving the positioning precision of a pan-tilt camera. The control method comprises: firstly, initialization is performed; a panoramic image of an application scenario is displayed on a display screen of a computing platform, a user selects a region of interest in the panoramic image of the application scenario, an image of the region of interest is stored as a target image, and the user selects one target image from a plurality of target images as a target to be rotated. The beneficial effects of the invention are that: control is performed on a software layer, so there is no need to modify the hardware elements of a traditional camera, the target can be accurately positioned through software operation even if the rotating axis of a camera is inaccurate, and there is no need to replace camera devices. Thus, hardware deployment costs can be greatly reduced, and the service life of camera hardware is prolonged. The present invention allows the user to balance the speed and precision of panorama composition and matching calculations based on the actual situation. The present invention is highly flexible.
