技术领域technical field

背景技术Background technique

地质灾害是指在自然或者人为因素的作用下形成的，对人类生命财产造成的损失、对环境造成破坏的地质作用或地质现象，遭遇破坏后，地表面容易发生裂缝，需要使用裂缝大小检测装置对裂缝的宽度进行检测，但是由于现有的裂缝大小检测装置只能地表面裂缝的宽度进行检测，而地表面下层的裂缝宽度与地表面裂缝的宽度不一致，难以检测导致地表面下层的裂缝的准确宽度数据，同时检测的过程中只能进行定点检测，裂缝较长，每一处的裂缝宽度都不一样，导致检测到的数据较为单一，难以将整体的裂缝宽度进行精准的检测。Geological disasters refer to geological effects or geological phenomena that are formed under the action of natural or human factors, causing loss of human life and property, and damage to the environment. After encountering damage, cracks are prone to occur on the surface of the ground, and crack size detection devices are required. The width of the crack is detected, but since the existing crack size detection device can only detect the width of the crack on the ground surface, and the width of the crack in the subsurface layer is inconsistent with the width of the crack on the ground surface, it is difficult to detect the cracks in the subsurface layer. Accurate width data, at the same time, only fixed-point detection can be performed during the detection process. The cracks are long, and the width of each crack is different, resulting in relatively single detected data, and it is difficult to accurately detect the overall crack width.
