Automatic adjustment method of laser level meter

The invention relates to the technical field of control or adjustment, in particular to an automatic adjustment method of a laser level meter. The automatic adjustment method comprises the steps that a grey-scale map is obtained, and edge points and non-edge points in the grey-scale map are obtained through a canny operator; calculating the gray frequency, the confusion degree and the similarity of each non-edge point; obtaining a first optimal value and a second optimal value of each non-edge point, and obtaining a background clustering center and a laser clustering center; calculating a background decision value and a laser decision value of each non-edge point, and dividing each non-edge point into a background point and a laser point; calculating a detection effect according to the background points, the laser points and the edge points; when the detection effect is greater than the detection threshold value, correcting the laser gradienter according to the edge points; when the detection effect is smalle
