Accumulated snow depth monitoring method based on machine vision

The invention relates to the technical field of meteorological monitoring, and discloses an accumulated snow depth monitoring method based on machine vision. The method comprises the following steps:acquiring an on-site shot picture acquired by a fixed camera of which a lens is over against an accumulated snow detection scale; measuring the real exposed length of the black scale by sequentially starting image processing modes such as image cutting, image graying and binaryzation, contour extraction and pixel conversion; and finally, obtaining the real depth of the accumulated snow based on the real exposed length, and then achieving the purpose of automatically measuring the depth of the accumulated snow, so that on one hand, compared with an existing manual measurement method, the measurement efficiency can be greatly improved, the labor cost is reduced, and the automation degree is high; on the other hand, due to the fact that only one black scale, one camera and one computer deviceneed to be arranged to ac
