Problems solved by technology

[0004] However, the existing machine vision detection equipment has obvious defects and cannot be applied to the road maintenance industry for tunnel defect detection
On the one hand, the cameras used in the machine vision inspection process are generally industrial line scan cameras, industrial area array cameras and digital cameras, resulting in high costs and the inability to flexibly adjust the inspection process; on the other hand, the overall structure of existing machine vision inspection equipment It is complex and cannot be flexibly adjusted, and the fixed speed of the detection vehicle is 10km / h, which results in low detection efficiency, and the price is as high as tens of millions, so it cannot be promoted and applied in the road maintenance industry

Abstract

The invention discloses a tunnel disease image acquisition device with an automatic photographing function, comprising a device support mechanism, an image acquisition mechanism, a camera control circuit and a vehicle speed output mechanism. According to the tunnel disease image acquisition device in the invention, the device support mechanism, the image acquisition mechanism, the camera control circuit and the vehicle speed output mechanism cooperate with each other to achieve a fast and clear effect of acquiring a complete image of the inner wall of the tunnel, thereby saving time and cost for detecting tunnel diseases, improving the accuracy of the detection result and reducing the detection error.

Description

technical field [0001] The invention relates to the technical field of image acquisition, and more specifically relates to an image acquisition device for tunnel defects with an automatic shooting function. Background technique [0002] With the development of science and technology, machine vision inspection has developed rapidly in various fields, especially in the field of dangerous work, which is gradually replacing manual inspection. Because machine vision detection has good automation and good detection accuracy, it can automatically collect images in tunnels to obtain tunnel disease information. Compared with manual detection, it has unique advantages, so it can be applied in the field of road maintenance. [0003] At present, the tunnel defect detection system is mainly divided into machine vision detection and manual detection. Among them, the manual detection method is that the inspectors block the road on one side of the tunnel, and manually measure the position ...
