| Abstract: | With the purpose of calibrating digital camera before photogrammetric task,this paper presents the method and process of establishing an simple indoor calibrating field.Firstly,the calibration field is established and the main steps include the choice of the calibration filed,production of sign's points and the measurement of coordinates,then the reliability of the calibration field is verified.The results show that the indoor field,which is established for calibrating digital camera,can be used in digital camera calibration.The digital image obtained by calibrated digital camera in this indoor field can directly be used for close-range photogrammetry in certain precision demand.The technique is very available and the cost is greatly reduced from before.It improves the traditional large-scale indoor digital camera calibration. |
