Errors reducing method of Laser 3D scanner

Abstract

This paper presents the factors that influence the form scanning processing by using the laser: light ambient, scanning surface, motion axial, focal length of the camera. This paper will present the method to reduce the error of the environment by using the camera calibration algorithms and the coordinate movements. This errors reducing method to solve the problem from local to genera: from solving errors created by the curve of the cameras to the laser-line width, to the dark gray threshold of the images by the camera aperture and coupling 2- movement axis to scanning-coupling more effectively.
