[0003] The sphericity of the spherical cover workpiece is crucial for the production of spherical cover workpieces, especially the defect detection of spherical surfaces and lenses, which has important reference significance for the production, equipment and later use of spherical surfaces and lenses. Among them, spherical covers are widely used in the field of monitoring equipment. Monitoring devices with spherical covers are suitable for various monitoring scenarios, such as traffic flow monitoring, public place safety, school and hospital security, etc. In outdoor environments, spherical covers can prevent the influence of strong sunlight, wind, sand, rain and snow on the monitoring quality. At the same time, the spherical cover not only plays a protective role, but also can enhance the image quality of the video.

[0004] The higher the spherical accuracy of the spherical cover, the clearer the video footage shot by the surveillance can be, the more uniform and clear the light can be transmitted, the more effective it is to avoid the appearance of strong light and dark corners, and the more effective it is to improve the clarity of the surveillance video.

[0005] However, the above-mentioned related technologies have the following defects: the production and manufacturing of spherical masks with high sphericity accuracy is completely feasible for today's industrial production, but a certain defective rate is inevitable in industrial production. At present, there are certain difficulties in detecting the sphericity of spherical masks. It is difficult to accurately detect the sphericity of spherical masks through existing testing equipment, and therefore it is difficult to accurately evaluate the quality of the produced spherical masks, which brings certain troubles to the subsequent use of the spherical masks.
