| 摘 要： | 普通相机拍摄的像片越来越成为近景摄影测量的主要数据来源,针对普通相机内方位元素不固定、图像畸变较大的问题,论文提出了先对立体影像进行内方位元素(x0、y0)和畸变系数k1改正、再建立核线影像的操作流程,推导了相关的数学模型,根据实例验证,得到了很好的效果。

| Abstract: | Images captured from general digital camera is gradually becoming the main data source of close-range photogrammetry.Aiming at the problems of not-fixing inner orientation elements or image＇s large distortion of the ordinary camera,this paper proposed a operation flow which was firstly correcting the inner orientation elements（x0、y0）and the distortion factor k1 of the stereo images,and then establishing epipolar line images.It also derived the related mathematical model.According to the example verification,the method had got a very good effect. |
