Research on Distance Measuring System Based on Single Vision with the Aid of a Laser Pen

Abstract:

In this paper, a study and analysis of a distance measure method based on single vision with the aid of a laser pen is proposed. In the method, a camera and a laser pen are used as measurement device. By comparing the lightness of the pixels, the laser point projected on the object is found out in the image. Then an orthogonal triangle using the distance between laser point and CCD center as one edge is set up. And Pythagorean Theorem is applied to calculate the distance between camera and measured object. Experiments in different lightness are carried out and encouraging results are obtained which prove that the device has nice measuring performance in appropriate lightness.
