With the rapid development and popularization of the automobile industry in China, the demand of automobile lamps is increasing day by day, and with the improvement of the automobile quality, the quality requirement of the automobile lamps is stricter and stricter. In order to improve the quality of the automobile lamp, a pin needle has been developed to replace a line connector on a PCB control board of the automobile lamp. Compared with a circuit connector on a PCB control board in the prior art, the novel process pin inserting needle is more efficient, and the quality of the car lamp is greatly improved. However, since the pin is thinner and longer and is easily deformed, many products using the pin need to be inspected in the manufacturing process and the shipment of the products. Before the development, various schemes are also explored, and the 3D structured light processing is adopted firstly, so that the effect is not ideal due to double images. And then the line scanning industrial camera is adopted, so that the effect is not good. And a common lens cone is adopted to find that the photo has larger distortion and insufficient depth of field. (the distortion coefficient is the difference percentage between the size of the real object and the imaging size of the image sensor) (the depth of field refers to the range of object distance measured by the axis of the camera in front of the camera lens or other imager and the imaging depth of field capable of obtaining a clear image.) the distortion of the common machine lens is usually higher than 1-2%, which seriously affects the accuracy level of measurement. Many vision manufacturers do not solve the problem well after many tests.
