I try to calibrate a photo, error

Solved

Hello,

calibrate a photo with 4 points by coordinates.

When I create it, error (see attachment).

One week ago it was working. Problem with a new software-update?

So I'm very sad about it.

Thanks for help.

I think, it's a software-problem, not my handling.

With 3.36.2 I had also a problem to calibrate photos.

After update to 3.37.0 no problem. Fix for "incorrect selection of photos for On-board calibrator".

Current 3.37.2 since some days.

Hello Ludwig,

for me it works with current version

In your screenshot "Punkt1" to "Punkt4" are closed

please open each of them and verify values of "photo pixel koords" and "map koords" are these set ?

Hello Wolfgang,

sorry, my mistake.

I've forgotten to choose the points on my photo, only wrote the coordinates from the background map.

Thank you for your help.

Hello Ludwig, balloni55,

how you made this mistake?

If one point is not correctly set, you just cannot add another and if there are not at least 3 valid points, Locus Map warns with "Insufficient number of valid points" warning.

Hello Menion,

with the calibrator for pictures four Points added.

But only with their coordinates.

I had forgotten first to add points on my picture (user guide, theme Image map calibration, number 2, step 1).

Hello Ludwig,

ah, got it. Perfect, thanks. Next time, in this case, app rather display something like "Not all calibration points are correctly defined".

Thanks,

Menion
