Abstract

The Algorithm of Measuring in Close-Range Photogrammetry based on Grid [Purpose] Due to the existence of various error sources in the close-range photogrammetry, the traditional photogrammetry algorithm cannot completely eliminate system error. The measurement precision often cannot reach the requirement and the calculation process is complicated. In order to solve this problem , a new measuring algorithm called grid measuring algorithm is presented in this papers. [Method]We structures an ideal grid measuring space according to image point of the fixed point. Then the interested object points are mapped to the grid measuring space by the image points. We can get the position by fusing the value according to the distance to the nodes.For illustration,a photographic example is utilized to show the feasibility of the grid measuring algorithm.[Results] The experimental results show that the error of grid measuring algorithm is controlled within half pixels. [Conclusions]The positioning precision of this algorithm is obviously superior to the traditional algorithm and the calculation is simple.
