I am currently using an M300 + P1 for multiple tasks including 2D and 3D mapping. I have not had a requirement to constrain the work area I am operating in when doing 3D models prior to now. The area I worked on the weekend bounded a large hotel property which was a no fly zone. When the area being modelled is close to a no go area , the oblique Gimbal Angle and the altitude of the flight become the constraints. When I work at 100m height and a gimbal angle of -45degrees, the projected overlap into the neighbouring property is approximately 125 meters. When it is set to -80 degrees, the overlap is substantially reduced. Obviously the lower the angle the better.
1. Can anyone advise on the sweet spot where the deformation of objects such as trees starts to increase? If I can work that angle then I can start playing with altitude which is also a factor. Unfortunately, I am operating in an environment where there are 40m trees, so that is one of the limitations I have been operating under.
2. Typically I have always flown mapping missions with the same camera gimbal angle. Has anyone been using different angles for different routes that are included in the one model, and if so how does this impact your final models?
3. Similar to number 2 above, I have always tried to fly at one altitude for the whole job. Has anyone had any experience mixing different altitudes in the same job?
Clearly, the P1 facilitates flights at higher altitudes while retaining exceptional GSD resulting in an efficient workflow, but the higher altitude has the disadvantage that in conjunction with Gimbal Angle it increases the flight area when performing Oblique photography which may be unacceptable under some circumstances.
