A method and apparatus for identifying an edge of a target object using laser distance measurement. The method comprises rotating a laser distance measuring head in intervals of a predetermined angle in a first direction. Further, at each step of rotation, directing a scan beam onto the target object at a point of incidence and measuring a distance between the laser distance measuring head and the point of incidence. When a difference between a measured distance at a first step of rotation and a measured distance at a second step of rotation exceeds beyond a predetermined threshold value, identifying, that an edge of the target object has occurred at the point of incidence of the scan beam corresponding to the second step of rotation, wherein the second step of rotation precedes the first step of rotation.
