基于Matlab的二维世界坐标重建

2D Reconstruction for World Coordinates Based on Matlab

计算机视觉技术研究的目的是要使计算机具有通过二维图像认知三维环境信息的能力。摄像机标定的目的就是要建立三维世界坐标与二维图像坐标之间的一种对应关系。论文为了实现二维世界坐标重建,依据摄像机标定技术与利用立体视觉方法进行二维重建的原理,建立了空间某一点图像坐标和世界坐标的对应关系模型,并在Matlab环境下验证了利用单目摄像机先定标求取投影矩阵之后进行二维世界坐标重建的可行性。实验结果表明该方法可行有效。

The research goal of computer vision technology was able to set the 3D environment information by the 2D image,camera calibration was to establish the relationship between 3D coordinates of the world and 2D coordinates of the image.In order to reconstruct 2D world coordinates,based on camera calibration and 2D reconstruction principle for stereo vision,a relationship model is established between the image coordinates and the world coordinates.Simultaneously the analysis verifies the feasibility of using monocular camera and then reconstructing 2D world coordinates in Matlab.Experimental results show that the method is practicable and efficient.
