There has been a number of threads in this forum and the others asking the question and it seems that no one has been able to offer an answer yet. After chatting with the DJI technical support people on line and performing some test today, I managed to come up with an explanation that seems logical. This is my test :



Angle too small

This warning only shows up when the previous waypoint is very close to the one being defined. It's so close that the app considers them to be the same point. When two neighbouring waypoints have the same position but differ only in the camera direction, the drone will hold it's position and just pan the camera from the direction defined for waypoint 1 to that for waypoint 2 when taking pictures. Apparently the app assumes that some minimum number of pictures will be taken between the two waypoints / camera directions. If the angular difference is so small that the angle delta betwen consecutive pictures is smaller than the step size of yaw control, the app will consider the mission to be inexecutable and reject the waypoint setting. The solution suggested by the DJI people is to increase the seperation between neighbouring waypoints.


Angle too Big

The maximum allowed change in camera direction depends on the seperation between neighbouring waypoints. The further they are apart, the larger the angle allowed. There is a rule in the app that the camera direction delta between two consecutive pictures cannot be too large or the resulting hyperlapse footage will look jerky. This puts a limit on the total change in camera direction in going from waypoint 1 to waypoint 2. The larger the waypoint seperation, the more the number of pictures that will be taken in between hence the larger the angle change allowed.

Makes sense ?

Yes, that makes sense, I will now go out and have some idea of what to do to prevent the error messages.

Makes sense, but there are also instances when you would just want photos, like for photogrammetry, so jerkiness is not an issue, but angle limitations are.
