Excavator automatic detection method based on image recognition

The invention discloses an automatic excavator detection method based on image recognition, which comprises the following steps of: 1, arranging a camera to continuously shoot a to-be-protected area at a fixed angle, and regularly intercepting images from the images shot by the camera; 2, detecting the intercepted image by adopting a target detection algorithm, and judging whether an excavator is detected or not and whether the probability of detecting the excavator is greater than a set threshold value or not; step 3.1, if the image is not greater than the threshold value, storing the image as a low-resolution image for future reference; step 3.2, if the threshold value is greater than the threshold value, entering a next early warning mechanism; step 4, entering an early warning mechanism which specifically comprises the following steps: step 4.1, remotely sending cable external damage alarm information to a wire protector; step 4.2, an on-site audible and visual alarm starts to work to carry out early warn
