In the first chapter , we introduce linear camera model and some general knowledge and several traditional methods of camera calibration , such as direct linear transformation and two - step method etc . in the second chapter , we talk about the method for camera self - calibration through translation movement of the camera
全文分为以下四章（其中第二、三和四章是本人的工作）：第一章介绍了线性摄像机模型以及摄像机定标的一般性知识和几种常见的传统定标方法，比如直接线性变换方法和两步法等。
The inner and outer orientation elements of non - mearsured camera are figured out in the method of direct linear transformation ( dlt ) on the basis of the known coordination of key points in the image . the tolerance analysis of inner and outer orientation elements is accomplished with the coordination of redundant key points . finally , the physical spacial coordination of the image points is calculated in the way of dlt
运用直接线性变换法( dlt ) ，根据测量图像中控制点的已知坐标，计算出非量测相机的内、外方位元素，使用多余的控制点坐标，完成内、外方位元素的误差分析，最后运用直接线性变换法根据测量点的像点坐标计算出相应的物方空间坐标。
