Underground drilling quantity detection system

An underground drilling quantity detection system comprises a depth camera and a processing device, the depth camera is based on distance perception, has the advantages of being all-weather, independent of illumination and stable in data, can resist interference of underground dark light and dense fog environments on drilling quantity statistics, and can detect the drilling quantity based on depth images collected by the depth camera. The processing device can automatically detect the drill rod target in the depth image and then track the motion trail of the drill rod target, when the motion trail meets the preset trail, 1 is added to the drilling number, so that detection of the drilling number is completed, and the method has the advantages of being accurate, real-time, efficient and the like, has higher robustness and is suitable for popularization and application. The device can work normally even in an environment without illumination and in a dense fog environment, can realize 7 * 24-hour all-weather re
