The positioning device 9 adopts a photoelectric switch, and the photoelectric switch automatically calibrates and positions when the origin of the speed dome passes through the photoelectric switch through an optical sensor. Because there is not mechanical contact and wearing and tearing in the optics mode, consequently adopt photoelectric switch can effectively reduce the fault rate, ensure high-speed ball location accuracy simultaneously.

A panoramic shooting method is characterized in that a camera 1 is driven to rotate continuously through a rotating motor 11 to obtain video information in a global axis range and transmit the video information to a video processing host system 3, and after the video processing host system 3 receives the captured video information, video connection and visual angle partition are carried out by taking a spherical coordinate as a unit and a time axis as a main line, so that partitioned and continuous video images in the panoramic range are realized. The imaging principle is a novel imaging principle, and is completely different from the mode of general multi-camera imaging splicing or manual intermittent adjustment of a single camera according to needs so as to obtain video information of different parts. The method specifically comprises the following steps:

step 1: after the camera module is manually fixed at a required position by the fixing mechanism 2 and started, the camera 1 rotates clockwise or anticlockwise in a certain direction at a set speed by the rotating motor 11, and initial position information of the positioning device 9 and video information obtained in the rotating process of the camera 1 are transmitted to the video processing host system 3;
