摘　　要：文章针对数码相机的特性,在建立摄像机的径向畸变模型的基础上,对数码相机进行了标定,并采用“两步法”求解数码相机的内外参数。同时基于计算机立体视觉理论,根据不同位置拍摄的二维图像的信息,进行了空间三维物体的重建,对比了用线性和非线性两种模型对数码相机进行标定的重建效果。Considering the character of digital camera, author does the calibration basing on radial distortion model. Two - stage technique is used to calculate the exterior and interior parameters. The linear equation makes the whole algorithm more rapidly and accuartely. According to the 2D information of pictures from different direction, 3D object reconstruction is done basing on the theory of computer vision. The reconstruction accuarcy basing on nonlinear model and linear model is discussed.
