Camera offset about anipose HOT 6 CLOSED

Hi @menor22 ,

I haven't tried calibrating with cropped frames, it might work. Let me know if you try it out!

However, it is better to calibrate with the full view and crop only when recording, as calibration performs better on the full camera view. In addition, this allows you to reuse the same calibration videos with different cropping for behavior.

For specifying camera offsets when cropping for behavior recording, you can do so in the config.toml file.

An example configuration (for three cameras named "A", "B", and "C"):

[cameras.A]
offset = [36, 165] # x, y offset from top left corner

[cameras.B]
offset = [279, 310]

[cameras.C]
offset = [92, 98]

Let me know if that makes sense.

Hi @menor22 ,

Have you tried this out? Did it work?

I think the original question is answered, but this should really be part of the documentation, so I am leaving it open for now.

Hi,

maybe it's a silly question, but...

How do I specify different starting point for cropping offset? I have videos of two rats that are cropped in the middle and it's obvious when I want to set the offset for the rat on the left, but have no idea how to do that for the one on the right. Let's say one has a compartment that starts at 0 and the other one is in a compartment that starts at 500 px. How do I specify it in config file?

Edit: I solved that. Didn't realize before that offset takes 4 values. Still for some reason I have a problem with offset of points in the 'right' part of the cage. Seems to be there only for cropped videos, when I have a full view it works fine.

@KonradDanielewski this is really a long time ago, but you only need to specify the top-left corner of your crop for the offset.
The width and height of the crop are irrelevant from a triangulation perspective as they don't actually change the coordinates

I'll just close this now, but feel free to reopen if you feel it hasn't been answered properly
