Mine car loading capacity detection method, system and device based on computer vision

The invention provides a mine car loading capacity detection method, system and device based on computer vision, and the detection method comprises the steps: obtaining an image of a loaded mine car through a camera disposed at a detection point, and enabling the camera to carry out the light supplement through a light source disposed in a correlation state with the camera; preprocessing the image, searching an edge contour, and obtaining a mine car contour and an ore contour; fitting a geometric shape based on the mine car outline and the ore outline; and calculating the volume of the geometrical shape, and calculating the corresponding ore loading capacity in combination with the ore density. Based on the image processing technology, the loading image of the carriage is collected and processed in the advancing process of the mine car, the loading volume and weight of the mine car are detected and are not affected by muddy accumulated water on a rail, and the carrying capacity of the whole mine car is accura
