基于线结构光的桌面3D扫描技术

为了研究基于线结构光的桌面3D扫描系统,将3D扫描所需进行的各项扫描仪标定工作进行了实验,使之得以在人较少参与的情况下自动完成。对图像进行了扫描算法研究,搭建了一套由摄像头、控制板、激光器以及上位机组成的装置。对摄像机进行了标定并通过实验验证了其获得结果的准确性。同时利用光平面方程对光平面进行了标定,利用阈值法和灰度重心法相结合,对光条中心进行提取。通过对物体三维扫描将所得扫描结果与扫描实物进行了对比,分析了系统的误差。该系统具有价格低廉,使用方便等特点。

A desktop three-dimensional scanning technology based on line structured light

The paper is to study a desktop three-dimensional scanning technology based on light structured.The system consists of a camera,a control panel,a laser and a host computer.The scanner has cheap accessible components and is easy to carry.The three-dimensional scanning for the scanner calibration has been adjusted so that it can be automatic.The accuracy of the results is also verified.At the same time,image processing algorithms for scanning are studied.Scanning can also be set up in only a few parameters under the conditions of automatic mode.Finally,the scanning results are compared with the objects,and the errors are analyzed.The experimental results show that the system can carry out 3D scanning of objects.The purpose of this paper is to develop a device of simple operation and low price.
