Paper Title:
Telecontrol Engineering of Three-Dimensional Measurements from Two-Dimensional Digital Photogrammetry for Scene Reconstruction
  Abstract

It set up a quick and high accurate method of 3D measurements from the 2D digital photogrammetry to reconstruct the scene by teleprocessing. Three types of feature marks in the matrix arrayhave been projected. The calibrations of the camera with fixed focal length have been calculated and compared before and after revision. The cross-shaped feature was the most accurate mark. And the cone barrel with sharp apex was also more accurate than the traditional round dot. The real case practices have been engaged in to verify the practicability and efficiency of the projects. In less than 10m with 6 points, the maximal error has been reduced to 0.029%. In around 20m with 20 to 34 ponits, the maximal error has been reduced to 0.046%. And it was far more accurate than the counterpart research (0.44%).The measurements results of the more big areas have been found to be instability. So the lawful choice of the single photogrammetric image scope should be limited to 20m. In the proper image scope (<26m), the telecontrol 3D measurements are very accurate and highly active. It can be positively applied to the remote scene reconstruction as well as other engineering vistas.
