摘要
提出了一种利用汽车车身的二维照片重建出其三维模型的算法。通过车身在不同方位的两张照片,选取一定数量的特征点,该方法能够计算出照相机的内外参数,进而得到车身表面对应特征点的三维几何信息,并利用UG软件完成曲面拟合以及进行装配。试验结果表明,文中采用的方法能达到理想的精度。
An approach is put forward to reconstruct a 3-dimentional auto-body model from 2-dimentional photos. By a set of points picked on auto-body＇s photos taken in different direction and position, inner and outer parameters of the camera and the 3-dimentinal geometric information of the feature points on auto-body can be calculated with the algorithm. At last, the curve surface is fitted and assembled. Experiment results show that good precision can he achieved arid that it is effective.
