When using Method A with varying FPS, the data extraction seems not to work.

failed attempts for resolving:

a very basic example is attached. The problem occurs at <measurement_area id="3" /> report_fehler.rar

could you reproduce the error?

@schroederbenjamin Please to be sure that there is trajectory information at both side of the measurement line. Otherwise, Method A does not work, because it is not possible to check whether the person go out or not. When the fps is small, the trajectory information will be not so fine. The distance between two neighboring position will be larger. there will be no trajectory information at the other side of measurement line. This could be the reason!

you can let pedestrian move a little bit more behind the exit to check it again. @schroederbenjamin

Should jpsreport give a warning in this case?

as I already have said, we repositioned the measurement line a couple of meters towards the centre of the room - no success. Did you check the supplied example?

I see, the poisition of the measurement line with id 3 is y=7.05. which is 16cm to the exit (y=7.21). If you check the trajectory file, you can find not all pedestrians' last y coordinates are larger than 7.05. for example, the agent with ID=21 left the room at frame 8. His last position is y=7.00 at frame 7. @schroederbenjamin

Please consider to extend the geometry such that ALL pedestrians are ensured to leave the geometry.
