Abstract

The application relates to a normal vector acquisition method and device of a photovoltaic panel, a medium and a screw locking robot, the method comprising the following steps: acquiring array point clouds and array images of the photovoltaic array which are superimposed and displayed in the same coordinate system, wherein the array point clouds and the array images comprise a plurality of photovoltaic panels; performing image recognition on the array images to acquire boundary features of the plurality of photovoltaic panels; acquiring the centroid coordinates of corresponding boundary point clouds based on the boundary features; acquiring panel point clouds corresponding to each photovoltaic panel in the array point clouds based on the centroid coordinates of the boundary point clouds and the size of the photovoltaic panel acquired in advance; and performing plane fitting on each panel point cloud to obtain the normal vector corresponding to each photovoltaic panel, thereby solving the problem that the locking direction of the screw is incorrect, resulting in low photovoltaic array installation quality.
