Design And Implementation Of3D Color Imaging Based On Laser Scanning

Laser measurement of distance has been widely used in industrial, military as well as other fields with its rapid devepment. And it’s hotspot using imaging tools to make the reconstruction of the three-dimensional model base on the outline data which comes from laser measurement. In this paper, we are going to rebuild the3D color model of a target which is scaned by a CCD camera to get its BMP format color image, and scaned by laser pulse to get its outline data. In order to combine the RGB of BMP color image data and the3D point cloud of same target, we design the frame of the project step by step, and the deployment of its software development. Based on the Visual C++tool, we use MFC frame and OpenGL as software foundation so that we can program on it efficiently.With this software system, we can also control the laser scanning to rebuild the3D color model and use OpenGL to reappear the model. What’s more, we design the algorithm to reduce noise of the point cloud data based on neighbor-data and median filtering, which finally achieve effect. In the future, it will be widely used and heihly improved to be applied in other fileds. Main work of this paper lists below:1) Analyse theory of laser detecting and color imaging base on laser theory.2) Generate3D colorful point-clouds of scanning object with laser detecting, scanning system and camera.3) Put forward the neighbor median filtering algotithm to reduce the noice of point-clouds, which achieve effect.4) Design and finish the3D color imaging system, which includes the control module, database designing, data fusion and so on.
