Other Abstract

The invention relates to a method for quickly acquiring camera parameters in the wide-range vision coordinate measurement, comprising the following steps of: establishing a world coordinate system according to a specific reference substance taking two optical targets as two known coordinate points respectively acquiring picture data of the two optical targets and corresponding image coordinatesthrough two CCD (Charge Coupled Device) cameras measuring the positions of the two optical targets through an electronic total station or a GPS (Global Positioning System), that is to say world coordinates of the two optical targets measuring the translation vectors of the two CCD cameras through the electronic total station or the GPS and substituting the world coordinates of the two optical targets, the image coordinates of the two optical targets and the translation vectors of the two CCD cameras into a measurement equation and resolving to obtain the focus lengths of the two CCD cameras and the horizontal declination angle of an optical axis. The method disclosed by the method has the characteristics of high speed, strong operability, easily-analyzed practical and algorithm performances, higher precision, suitability for long distance and the like and the camera parameters can be solved linearly once by only placing the two optical targets.
