Binocular module lens assembly fool-proof detection method, system, device and equipment

Abstract

The invention discloses a binocular module lens assembly fool-proof detection method. Light transmitted by optical filters in different lenses is different, so that light sensed by an image sensor is also different, finally color features in obtained images are also different, subsequently, whether the assembly of the to-be-detected lens and the image sensor is correct or not can be judged based on the color features of the image. Therefore, the mode can realize automatic detection of binocular module lens assembly, does not need manual intervention, improves the detection efficiency and precision, is good in fool-proof effect and low in cost, is not influenced by ambient light, and does not need to consider additional light supplement. The invention further discloses a binocular module lens assembly fool-proof detection system, a binocular module lens assembly fool-proof detection device and binocular module lens assembly fool-proof detection equipment which have the same beneficial effects as the binocular module lens assembly fool-proof detection method.

Description

technical field [0001] The invention relates to the technical field of foolproof detection, in particular to a foolproof detection method, system, device and equipment for binocular module lens assembly. Background technique [0002] The binocular module lens in the binocular camera includes a color image sensor, an infrared image sensor, a color lens and an infrared lens, and the application scenarios of the two sets of image sensors and lenses are different. During assembly, there is a strict correspondence between the lens and the image sensor. Specifically, the color lens is matched with the color image sensor, and the infrared lens is matched with the infrared sensor. The appearance of the two sets of image sensors and the appearance of the two sets of lenses are very similar. It is very easy to be confused during assembly, and wrong assembly will cause abnormal images of the binocular camera. Therefore, it is imperative to check whether the binocular lens and image sen...

AI Technical Summary

Problems solved by technology

[0005] Artificial naked eye detection is the most primitive detection method. The lens is distinguished by carefully observing the shape and color of the lens on the two lenses, and the components on the PCB (Printed Circuit Board, printed circuit board) where the two image sensors are located The position layout is used to distinguish the image sensors. The entire assembly and inspection process is not controlled, not fool-proof, the detection efficiency and accuracy are low, and it is easily affected by the emotion and fatigue of the inspectors.

[0006] 2. Position limit assembly fool-proof detection between boards

[0007] Position restrictions are made on the PCB where the image sensor is located and on the lens corresponding to the image sensor to prevent fooling. Although this method can achieve foolproofing, it needs to be re-opened, which is costly.
