Description
Technical Field

Background
As shown in fig. 1 and 2, the metal ring 1 for the camera needs to image the outer shape of the metal ring 1 to detect the defect position, and the area position of the metal ring is divided into: a front area 101, a side arc area 103, and a back area 104.
The front area 101 is a plane of the metal ring 1 in a top view angle, and the defects such as scratches, pressure damages, different colors, adhesive position foreign matters and the like on the plane need to be imaged; an arc-shaped edge region 102 is also arranged around the front surface region 101 of the metal ring 1, defects such as scratches, pressure damages, abnormal colors, A + non-abrasion and the like of the arc-shaped edge region 102 are also required to be imaged, a region 0.3mm below the top surface of the metal ring 1 is an A + surface, and the rest positions of the metal ring 1 are C-level surfaces.
At present, there is a deficiency in imaging the side arc region 103 and the front region 101 of the metal ring 1: an area-array camera is used for imaging the side arc-shaped area 103, the imaging precision of the area-array camera is low, the shooting frequency is high, the imaging time is long, and the installation space of a light source camera is large; reason analysis: if an area array camera is used in the side arc-shaped area 103, the shooting area is small, and a low-magnification lens needs to be configured to meet the basic field of view requirement, so that the imaging resolution is low; the shooting can be completed only by shooting for a long product for multiple times, and the shooting can be completed only by shooting for the cambered surface imaging for multiple times, so that the shooting time is long, the algorithm processing time is long, and the whole system is complex; such a system uses many cameras and light sources and has a large installation space.
At present, most of the front area can be shot by adopting coaxial light for imaging the front area 101, but because of the characteristic problem of a light source, the imaging effect of the coaxial light on the area of the arc-shaped edge area 102 is poor, and the coaxial light is required to be matched with the light source sensitive to the edge area for simultaneous shooting and imaging.
In summary, the problem that the imaging effect on the side arc region 103 and the front region 101 of the metal ring 1 is not ideal needs to be solved.
