Abstract
A method for distance measurement is proposed in which two or more laser light emitters emitting converging collimated laser beams, an image sensor, and an image processor are positioned on a baseplate. The output of the laser light emitters from light points on surfaces substantially opposite the baseplate. The image sensor captures images of the projected light points. The area of the polygon or the length of the line resulting from connecting the light points is extracted by the image processor and compared to values in a preconfigured table relating polygon areas or line lengths to distances from the baseplate to surfaces.
