摘　　要：为了实现普通数码相机应用于摄影测量任务前的检验,提出了一种简易室内数码相机检校场的建立方法和流程。首先进行检校场地的建立,包括场地的选择、标志点的制作及其坐标的量测,然后对检校场的可靠性进行了验证。结果表明所建立的简易室内数码相机检校场能够满足普通数码相机应用于近景摄影测量的检校要求。并且,检校场建立简易,费用较传统数码相机检校场大大降低,是对传统大型室内数码相机检校场的改进。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.
