The basic error equation of line photogrammetry and its modified form were addressed.

This paper mainly focuses on analysis for the redundancy and relativity of the observation in line photogrammetry.

3-D shape analysis in the industry photogrammetry;

The cultivation of practical skills and creativity of the students of the course of "Photogrammetry";

During trajectory-tracking photographic measurement,on occasion comes forth the problem that the tracking stations time is asynchronous,so the data can t be put into usual processing.

In this paper, A major study is distributed attitude measurement system based on the method of photographic measurement, and applied to the study of deck deformation field.

Based on a summary of the methods for photographic survey of strike-dip of structural surfaces on rock slopes, the vanishing point deduction method and its calculation formula are proposed, and the method of vanishing line is further illustrated.

The basic method of data processing in digital photographic survey is put forward in deatil.

By using this composition the method of drawing perspective pictures from the second to the third is given,and the formulas about reconstructing 3-D space by using two perspective pictures are provided, it s more simple than the previous calculations about the photographic survey and reconstucting 3-D space.
