| 摘 要： | 给出了用DSP实现基于图像的3D场景重建的方法和步骤.3D场景重建主要由摄像机标定、图像采集和基于图像的重建3个部分组成.在摄像机标定中,使用摄像机作为测量装置来确定它的内部和外部参数,比对摄像机直接进行测量更为方便;利用摄像机、SEED-VPM642实时图像处理应用平台和PC机构成的系统进行图像采集,DSP芯片与PC机的图像传输采用PCI通信实现;采用体素着色(Voxel Coloring)方法实现3D场景重建,使现实物体在计算机虚拟世界中得以重现.

| Abstract: | A method of image-based 3D scene reconstruction using DSP chip is proposed,which consists of camera calibration,image collection and scene reconstruction.In the process of camera calibration,camera is utilized as measuring device in order to compute the intrinsic and extrinsic parameters,which is more convenient than measuring the camera directly.The image collection is carried out by the real-time image processing platform of SEED-VPM642,the camera and the computer system.The image transmission between DSP chip and PC is achieved by PCI.The 3D scene reconstruction is accomplished by the means of voxel coloring at last. |
