Flight altitude, ground resolution and camera interval
reference:
Exception: when the standard flight height cannot meet the ground resolution
required by the project, in order to ensure the ground resolution first, we can split the
survey area and collect the higher area separately. When collecting separately, we can
adjust the 2 times in the formula to 1.5 times, and increase the overlap to 85% to
ensure the data integrity of the higher area; in case of high mountain height and large
slope area, ladder type stratified flight can be adopted to ensure the overall model
accuracy and ground resolution.
Flight area planning
First of all, it is necessary to determine the key flight area. Due to the acquisition
method of oblique photography, the 3D image data of the edge area are generally
lack of data with poor accuracy. Therefore, we must put the key area in the center of
the flight area when planning the flight area, and set the minimum range as the edge
extension of the key area 1 In the post-processing process, the edge area can be cut
off.
