The testing method of horizontal error of the beam in laser swinger is expounded in this paper, in which the horizontal error of beam in characteristic direction, its testing steps, and the method of data processing are presented.

A series of research is carried out on the key technologies of digital close range industrial photogrammetry,such as the basic measurement theory,center sub-pixel localization of targets,self-calibration of digital camera,automatic image points\' match and bundle adjustment algorithms.

Then camera self-calibration was applied by using the bundle adjustment algorithm to optimize the initial values.

The initialize calibration result by Zhang Zhengyou calibration arithmetic is optimized by bundle adjustment of the digital close range industry photogrammetry.

A measurement and adjustment method for the level error of radar antenna pedestal during installation is described in detail in this article.

In this article, we will discuss the ways of how to get their stable numerical solutions, in which the continous and discrete regularization method, with and without knowing the error level 6 of input data, are presented and a regularization strategy based on linear approximation for identifying the nonlinear source term is also given.

The principle of bundle adjustment and weighting schedule of different measurements is discussed.

In this paper,two calibration method,which are based on DDM~~([3])(Digital Distortion Model)and additional parameters bundle adjustment algorithm,are discussed to determine the internal geometric and systematic distortion parameters of the digital camera.

A novel method based on factorization and bundle adjustment,as well as its principle and implementation is presented.
