[0002] The camera protective cover is widely used in the fields of security monitoring, vehicle-mounted camera, industrial vision and the like, and is mainly used for protecting the camera lens from the influence of external environment such as dust, water vapor and collision. However, the material, thickness, curvature and the like of the protective cover can have a negative influence on the image quality of the camera, for example, causing image distortion, resolution reduction, halo and the like. Therefore, the image quality of the protective cover needs to be detected in the production process to ensure that the optical performance meets the requirements.

The real scene detection of the image quality of the protective cover has the disadvantages of environmental light interference, high scene complexity, lack of standardized reference, difficult angle adjustment, dynamic factor interference, poor repeatability and inability to quantify the image quality problems, resulting in inaccurate and unreliable detection results.
