Problems solved by technology

[0003] During use, the camera’s strip-shaped field of view needs to be consistent with the linear light spot of the laser light source. When the strip-shaped field of view is inconsistent or deviated from the linear spot, it will cause the incomplete part of the captured picture to have no image, resulting in the inability to obtain a clear picture of the truck parts. The system cannot effectively identify the faults of the captured pictures, which seriously affects the work efficiency and leaves hidden dangers for the safety of trucks.
[0004] In the prior art, in order to realize the alignment of the strip-shaped field of view and the linear spot of the line-scan camera, the line-scan camera or the laser light source is directly rotated by hand to align the strip-shaped field of view and the linear spot, which is difficult and inefficient. , the positioning accuracy is poor, and the deviation angle is not easy to adjust

Abstract

The invention relates to a lens module of optical detection equipment, particularly to a linear light spot module. The linear light spot module comprises a camera and a laser light source; the camera and the laser light source are positioned at the two ends of a base respectively; the camera is mounted on a camera angle adjustment apparatus; the camera angle adjustment apparatus is mounted on the base; the laser light source is mounted on a light source adjustment apparatus; and the light source adjustment apparatus is mounted on the base. The linear light spot module provided by the invention has the advantages of simple steps of realizing band-shaped view of the linear array camera and alignment of the linear light spot of the laser light source, and high alignment speed, high alignment precision and the like.

Description

technical field [0001] The invention relates to a lens module of optical detection equipment, in particular to a line spot module. Background technique [0002] In order to ensure the safety of railway wagons, the railway system has promoted the application of (trucks, passenger cars, EMUs) trackside fault dynamic image detection system. In this system, a high-speed industrial digital black and white camera is used to take pictures of the parts of the wagons that need to be detected. , and then the detection system detects the pictures of the car body parts taken, and automatically judges whether there is a fault. [0003] During use, the camera’s strip-shaped field of view needs to be consistent with the linear light spot of the laser light source. When the strip-shaped field of view is inconsistent or deviated from the linear spot, it will cause the incomplete part of the captured picture to have no image, resulting in the inability to obtain a clear picture of the truck p...
