Line laser contour extraction method and device, electronic equipment and storage medium

The invention discloses a line laser contour extraction method and device, electronic equipment and a storage medium, is applied to the technical field of laser measurement, and provides the method for determining a scanning direction according to a laser direction in a line laser grayscale image in order to solve the problem that existing line laser contour extraction is inaccurate; the scanning direction is perpendicular to the laser direction; scanning pixels in the line laser grayscale image according to corresponding rows or columns in the scanning direction, and determining pixel extreme points of each row or column; generating an extreme value contour corresponding to the line laser grayscale image based on the pixel extreme value points of each row or column; determining each abnormal region and head and tail contour points of each abnormal region from the extreme value contour; for each abnormal region, taking a connecting line between the head contour point and the tail contour point of the abnormal
