stereo calibration problem & ask for calibration results
-
Hi ,
I have some issue when i run voxl-calibrate-camera stereo.
I cant do stereo calibration.
Because the VOXL web portal shows nothing on camera calibration overlay page.So, may i ask for all the camera calibration results?

What do you mean by nothing on the portal camera calibration page? Can you see the stereo image frames? If not, the calibration file won't help. Can you share a screen capture of what you mean?

Dear Chad,
Thanks for the reply.
I can't see the stereo image.
By the way, voxl- calibration-camera tracking works fine on the portal.
-
Can you see the raw stereo camera stream in portal?
-
Ya, it works well.

Hi all,
We followed the following tutorial to upgrade the flight system image to version 1.3.1.
https://docs.modalai.com/Qualcomm-Flight-RB5-system-image/But We didn't save the calibration files in /data/modalai and lost them.
The voxl-version now :
voxl-inspect-services :
==========================================================
So I tried to calibrate the stereo camera by voxl-calibrate-camera stereo by following this guide.
https://docs.modalai.com/calibrate-cameras/The problem is that the portal didn't display the stereo calibration images (Camera Calibration Overlay),
but I can see the raw stereo camera stream in portal.
@Chad-Sweet @Alex-Gardner Could you give me some advices?Thanks.

Are you trying to calibrate "stereo" or one of the specific ones, when we have multiple sets of stereo cams they're named "stereo_front" or "stereo_rear" and you'll need to specify when running the calibration tool
-
I can calibrate stereo by using "stereo_front" and "stereo_rear" now.
But I cant detect the chess board in a frame which rectangle is small.I will make a new chess board for calibration.
Thanks! -

Hi! I am having a similar issue. Which checkboard did you make in order to successfully run calibration when the rectangle is small?

@dtsbourg There is some good info here: https://docs.modalai.com/calibrate-cameras/
