hi-res image quality difference VOXL and VOXL2
We are currently working with both the VOXL (SDK1.1.2) and the VOXL2 (SDK1.1.0) and we noticed some quality differences between the two platforms. The colors in the image taken with the VOXL (first image) seem to be better than on the VOXL2 (second image). Also the image seems to be more blurry on the VOXL2 while taken with the same camera (IMX412).
Both platforms were set to hires only, with AE_MODE set to "isp".
On the VOXL2 the camera is connected to HW sensor ID 2
Is this a known isue? or is there a way to get the same quality on the VOXL2 as on the VOXL?
We also noticed the snapshot on the VOXL not having the wierd artefact the VOXL2 has (as mentioned in this post https://forum.modalai.com/topic/2546/some-issues-with-voxl-camera-server-1-6-2?_=1707751139845)
We can look into the difference of image quality. Can you please clarify a few things:
- how are these images captured on VOXL1 and VOXL2 ? Are you looking at h264 / h265 encoded streams? Is the approximate bit rate the same?
- are both cameras focused properly (or is it exactly the same camera module swapped between VOXL1 and VOXL2)?
- what are the resolutions and FPS of the images that you are looking at?
Hi @Alex-Kushleyev thanks for the reaction
To clarify, both images are take using the voxl-logger (from the hires_color stream), both the video streams are disabled on both the VOXL1 and VOXL2. (Both images are a crop from the full image, because the full image was to big to upload, and most of the rest of the image was a white background.)
The same camera is switched between the VOXL1 and the VOXL2, and the images are taken from the same distance to the object in the image.
VOXL 1 was set to 3840 x 2160 resolution, and the FPS was set to 30
VOXL2 was set to 4000 x 3000 resolution and the FPS was set to 15
