Hi,
I wanted to know the displacements between the various cameras on the euclid sensor and for getting this information i did a rostopic echo /tf_static on my euclid device's terminal. Although the transform data given for most frames seems correct, I think the transfrom data for the fisheye camera frame is wrong. I say so because camera_fisheye_frame is the child of camera_link frame and the camera_link frame coincides with the camera_rgb_frame. So, the camera_fisheye_frame must be about 8 to 9 cms toward the left of the camera_rgb frame but the information published by the /tf_static topic does not correspond to this. I will be grateful if someone can verify this can give me the correct displacement between the camera_rgb frame and the camera_fisheye_frame.

Hi guys,
I printed out the /tf_static and the values for the fisheye transform that I got were around 2.7-3cm.
The distance between the fisheye and the left IR camera (to which everything is aligned) is 30mm, so the results are accurate.
I hope this makes more sense now.

Hello SubMarIn,
Thanks for reaching out!
There are several known issues with Euclid's fisheye camera as you can see in https://communities.intel.com/docs/DOC-111978 https://communities.intel.com/docs/DOC-111978. However, I don't see any issue regarding a misplacing of the fisheye's frame.
Please let us investigate about this, we'll get back to you as soon as possible.
