Workpiece edge measurement method and device, electronic equipment and storage medium

The invention provides a workpiece edge measurement method and device, electronic equipment and a storage medium. The method comprises the steps that a left image and a right image, collected by a binocular camera, of the edge of a to-be-detected workpiece are acquired; line-line matching is carried out according to at least one light ray in the left image and at least one light ray in the right image, and at least one line matching pair is determined; according to the initial head edge point of the first light ray, the initial head edge point of the second light ray, the initial tail edge point of the first light ray, the initial tail edge point of the second light ray, the gray gradient value of each point in the first light ray and the gray gradient value of each point in the second light ray in each line matching pair, the line matching pair is obtained; determining a target head edge point and a target tail edge point of the projection light corresponding to each line matching pair; and according to the
