I have bought this camera module with 180D fisheye
In camera control i can see crystal clear the camera but while trying to calibrate camera lens
I use
Lightburn: 1.5.06
Windows: 11 23H2 22631.3447
Camera module: ELP-USB48MP02-L170
There might be a lens limit here. Asking internally.
I’ve never seen someone use a 180 lens.
Confirmation: a 180 lens will be ‘damn fussy’ - but doable. The distortion is so high with lenses like this that it’s harder to get the pattern finder to match the circles pattern.
We recommend a different camera, or lens, if possible. Else, keep trying to isolate the image to be JUST the dot pattern.
Unfortunately i have only 18cm height to capture 100cm x 62cm , that’s why i chose 180d
i think that the 180d is not the issue, because if you noticed it captures only a small part and of curse it cant see the pattern
also i noticed that it tried to shoot photo with 8000x6000 resolution
Versus what? That seems a reasonable resolution for a 48MP sensor.
The extreme FOV makes the lens calibration process extremely finnicky. I’d suggest trying to do the lens calibration away from the laser in a position where you have very minimum background distraction.
I’m not following this. You can see the entire image in the lens calibration window.
When it captures to identify the pattern , and not in live stream, you will see that i render only a small upper left part of the image
It’s not clear to me what this image is showing. Where do you see this? Can you provide a full screenshot for where this is occurring?
The live stream from camera control shoes all the view but the capture button shots only a small part up left. Its like it captures only 8 MegaPixel and cant see the pattern
From what screen are you capturing the screenshot? I don’t recognize where this is coming from. Or are you compositing this from multiple screenshots? If so, can you provide a full screenshot of the original image?
LightBurn shouldn’t have an issue displaying a huge image size - but your camera may only be reporting out a limited crop resolution when LightBurn asks the camera for an image of the bed.
I’ve asked internally for some assistance with diagnostics here - I’d like to know what your camera is responding with when LightBurn asks for an image capture.
I edit the image to show you what exactly is happening, all actual screenshots are available in the 1st post
The case i easy. For some unknown reason the live stream inside Lightburn shows all 48MP but the capture inside the Lightburn says that captures 8000x6000 but it displays only a part of it as i mention in the image above
That could be a case.
but when i use another app to take a photo, it captures it ok and displays it as it be
Sorry to step in.
Have you tried fiddling with the following settings?
The Camera Alignment Wizard will not work properly if you haven’t gone through Lens Calibration completely. Your focus should first be there.
Have you attempted to do the lens calibration process in a different setting?
I am trying do lens calibration wizard of course and not alignment
yes i tried to but also like yours, the resolution is disabled.
The screenshot that you took the dark corner image from was from camera alignment was it not? The images taken during alignment are not going to be representative of expected outcome without having first achieved lens calibration.
This isn’t to say that there may not be other problems at play but that’s not yet apparent.
Have you tried changing the camera location and hand holding the calibration pattern to see if you can ever get a successful capture even with a bad score?
