| Abstract: | In order to improve the efficiency of electronic theodolite systems,combining image processing technology with the traditional measuring principle,an automatic spatial coordinate method for electronic-laser theodolites based on image interpolation was represented.First,the system structure was represented,then the process to locate the center of the target by centroid algorithm with sub-pixel position accuracy was introduced after optical magnification as outer CCD camera worked in tele-focus mode with shor... |
