In the process of route setting, the course overlap determines the number of images
and the interval of photographing, and the side overlap determines the number of
routes. Generally, the two overlap degrees can be set as the same. If it is necessary to
reduce the amount of data or adjust the flight efficiency of a single flight, a single
value can be used.
Trim
The overlapping degree of foundation is not recommended to be less than 65%, and
the common overlap is 75%, and it is not recommended to exceed the maximum The
overlap degree determines the reference data of ground image in the restoration
process. Theoretically, increasing the overlap degree can increase the accuracy of the
model. However, if the overlap degree is too large, it will reduce the field efficiency
and increase the amount of data processing in the later stage, and the increase of
model accuracy is not obvious, so please make reasonable adjustment according to
the actual needs.
Flight altitude
In order to ensure the integrity of data acquisition, the general flight altitude can refer
to a standard: (altitude of the highest point in the survey area - the height of the
take-off point) × 2, which is used as the standard flight altitude. This is to ensure that
the data of the high point in the survey area can be collected completely. If it is ideal
to take off at the highest point or higher place in the survey area, the altitude setting
only needs to consider the ground resolution and flight safety In addition, the ground
resolution can be ensured by changing the focal length of the lens;
