Abstract :
We propose an electric scanning laser rangefinder based on controlling the intensity of plural light sources. The method first projects two different-powered light patterns with almost uniform intensity, and a parabolic light pattern with a single peak which combines the outputs of each light source. From our experimental results, we conclude that the proposed electric scanning approach is effective for the 3D surface measurement of Lambertian objects with various colour patterns and specular objects.
