Projectile clearance measurement technology based on linear laser displacement sensing

In view of the problem that the gap value cannot be measured by video surveillance, which is the main qualitative monitoring method for the gap in the buried bomb cabin, and it costs a lot of manpower and testing resources, a new gap measurement technology based on linear laser displacement sensing was proposed. The displacement sensing system based on line laser is designed, and the high precision gap displacement measurement based on line laser displacement sensing is realized. At the same time, by setting up a simulation test scene, the system is compared with the photogrammetry method based on vision, and it is verified that the measurement accuracy of the system can meet the requirements under the measurement scene.
