Claim 5:
6. The method of positioning the laser pointer light source according to claim 4, wherein the determining the target vertical distance information between the laser pointer light source and the first plane according to the plane position information, the first position information, the first photosensitive information, and/or the plane position information, the second position information, and the second photosensitive information comprises:
determining a first included angle information according to the first photosensitive information, and/or determining a second included angle information according to the second photosensitive information;
determining first vertical distance information between the laser pointer light source and the first plane according to the plane position information, the first position information, and the first included angle information, and/or determining second vertical distance information between the laser pointer light source and the first plane according to the plane position information, the second position information, and the second included angle information; and
determining the target vertical distance information according to the first vertical distance information and/or the second vertical distance information;
wherein the first included angle information is an angle value of a first included angle formed by a first optical path and the first plane when light of the laser pointer light source is projected to the first laser projection position; and
the second included angle information is an angle value of a second included angle formed by a second optical path and the first plane when light of the laser pointer light source is projected to the second laser projection position.
