Embodiment Construction
[0029] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.
[0030] The open-pit mine stripping amount calculation method utilizing aircraft aerial images of the present invention is characterized in that it comprises the following steps:
[0031] A) Mission planning: According to the geographical conditions of the open-pit mine, plan and design the flight path of the aircraft; check and calibrate the digital camera carried by the aircraft, and measure the focal length, principal point, and pixel size parameters of the camera;
[0032] B) Data acquisition: Control the aircraft equipped with a digital camera to take off at a flight altitude of 100-500 meters; control the digital camera to take aerial photography, set the focus mode to autofocus, and the shooting mode to continuous automatic shooting to ensure that the sequence of images overlaps along the course ≥ 60%, side overlap ≥ 40%, ima...
