基于数码相机图像的三维重构

针对传统三维坐标测量方法的局限性，提出了利用数码相机对物体进行三维重构，达到对物体进行非接触测量的目的．采用标准图像法对数码相机内部和外部参数分别标定，与传统的相机标定相比，简化了求解的复杂性．基于同一物体的两幅图像，给出了其三维重建理论和算法．并举例说明了三维重构的具体实现步骤和方法．

3D reconstruction based on digital camera images

Aiming at improving the limitation of traditional 3D coordinates measurement,the use of digital camera images to achieve 3D reconstruction is brought forward.This is a new type of nontouch measure ment.Standard graphics method is introduced to solve the calibration of camera's interior and external parameters.Compared with traditional calibration method of camera,it greatly reduces the complexity of the solution.Then the theory and algorithm about 3D reconstruction is described,which is based on two digital camera images of an object.Finally,a realized example and its steps of 3D reconstruction are presented.
