Embodiment
[0028] refer to figure 1 , this embodiment provides a method of earthwork calculation based on UAV aerial survey technology, the specific process is as follows:
[0029] 1) UAV aerial survey data collection
[0030] Choose weather with high visibility and low wind speed for aerial survey data collection.
[0031] In order to improve the accuracy of the aerial survey, it is necessary to arrange four image control points around the falling rocks. The coordinates of the center point can be measured directly by using on-site inkjet crosshairs, and the coordinate values are converted into the WGS84-UTM coordinate system.
[0032] Adopt the manual flight acquisition mode, fly around the falling rocks, and collect image data from each position sequentially from bottom to top. The overlap rate between adjacent images must be guaranteed to be more than 80%, and the distance between the UAV’s aerial attitude and the target object must be guaranteed. Around 30m-50m.
[0033] 2) Poin...
