Working face video snapshot-based three-dimensional geological model dynamic correction method

The invention relates to the technical field of coal seam model correction, and discloses a working face video snapshot-based three-dimensional geologic model dynamic correction method, which comprises the following steps of: when a coal cutting cycle is in an intermittent period, controlling a plurality of anti-explosion cameras to positively shoot a coal wall image formed by the latest coal cutting cycle cutting of a working face at the same moment; coal wall images at all moments are obtained according to the time sequence, the coal wall images are spliced, and a working face coal wall image is formed; converting the sizes of all objects in the working face coal wall image based on the working face coal wall image according to a preset calibration object to form a new working face coal wall image; based on the new working face coal wall image, forming a two-dimensional profile map corresponding to the working face coal seam structure; according to the two-dimensional profile map, fusing a slice contour lin
