For example, the automatic mesh strain measurement technology widely used in the stamping forming process of automobile parts is to print standard meshes on a steel plate, then use a stamping machine to form the meshes on the surface of the formed part, take pictures of the surface of the part from different angles, and finally use a computer to analyze and process the images to calculate the geometric position information of the meshes on the surface of the part so as to obtain the strain of each part of the part and provide accurate data for the adjustment of a die. To make the automatic measurement adopting the image analysis technology faster and more accurate, the quality of the image must be high, and in the field photographing process, the ambient illumination can rarely meet the requirements of test analysis, the ambient illumination is poor, the lateral light is not good, and the overexposure is not good, so that the measurement efficiency and the integrity of the result are seriously influenced in the actual test process.
The high light reflection of the metal plate surface makes the metal plate easily have the phenomenon of local over exposure and insufficient exposure of other parts under the condition of poor ambient illumination, especially when the surface appearance is uneven, and the whole exposure quality of the photo cannot be improved by adopting a flash lamp. The problem can be effectively solved by erecting the surface light source around the photographed part to improve the overall exposure quality of the photo, but the problem is difficult to realize in an unfixed operation site and the surface light source is inconvenient to carry. In view of the above, a flexible exposure assisting device is provided, which is used for adjusting the exposure environment in a small space, and it is very necessary to improve the exposure quality of an image.
