calibration doesn work in depthai python into env. or with ROS launch about depthai

Check under other windows, there should be a green window with "calibration complete" or something that you'll need to close. Pressing Q usually closes these windows.

Calibration has been overhauled over the last year, it's changed an awful lot, which branch of depthai are you running the calibration from? Regarding the polygons, they were only ever a guide rather than a requirement, the window with the dots you're seeing is a coverage map showing where the device has captured the location of a marker. If you ensure you've an even distribution you know you'll be getting a good set of images for calibration.

Speaking of which, how many images are you taking? If you aren't getting decent coverage it's worth increasing the number of images captured by using the -it flag.

They've updated the docs too:

I've never used the dynamic calibration script and I didn't know there was one for ROS either, I may have to have a look at that one. I've only ever done calibration by installing from source using the depthai repo, I'm using an FFC-3P modular camera so this wasn't documented anywhere at the time.

Calibration is definitely in this repo by the way, make sure you run the command to update all the git submodules and the install_requirements.py script and you should be on the latest version of everything.

Any insight on this? Passed 3 days and I cannot use the camera

Tried also recalibration online script also sends error...

Last Depthai , clean installation following guide and using .env.
As you can see in the terminal text it tooks 39 , as it is in the guide, there is not other windows. I just made note the polygons in case could be related to the issue as they are in the guide.
Also the re-calibration script doesn't work, and the ROS one so no calibration tool is working in fresh install following the guides.
From where? depthAI from calibration manuals, no idea if it is SDK, depthay-python or depthai core . I guess it is depthai-python, they are python scripts in a python.env

Is there any update on this issue?
I've got exactly the same problem with my camera.

They never answered

so may i ask how you could calibrate the camera?

[MSaeedMp]

I just found the solution. Run the calibration.py using vscode (in its terminal). Then it'll work!
Hope this can help you out.
