Description
Technical Field

[0002] Whether it is cement or asphalt pavement, after a period of use, various damages, deformations and other defects will appear one after another. Common early diseases include: cracks, potholes, rutting, looseness, subsidence, bridge head culvert top jumping, surface damage, etc. Pavement crack detection equipment is a device specially designed to detect cracking phenomena in the road surface.
[0003] Pavement crack detection is usually carried out using drones. The drone flies above the road to be inspected, with its camera aimed at the road surface. The captured images are transmitted to a remote terminal for inspection via a data transmission module.
[0004] Most of the drones nowadays do not have a special function for detecting road cracks. The road crack detection equipment needs to be manually installed on the drone, and the installation structure of the detection equipment cannot be adjusted at will. When reinstalling, it is necessary to perform additional hole drilling operations according to the model of the drone, which makes disassembly and assembly very inconvenient. The existing drones with shooting functions can only perform simple rotation adjustments. When accurately shooting road cracks, the drone needs to stop at the top of the road surface, and the camera cannot be adjusted to the top of the crack at will. Multiple debugging is required to achieve accurate shooting, which is inconvenient to operate. Utility Model Content
