ZED X Mini - can't read frame by opencv

Software C++
1

Hi,

I’m trying to calibrate the ZED X Mini camera underwater, with Jetson Orin NX, Jetpack 5.1.2.
Following How to Calibrate your ZED camera with OpenCV - Stereolabs, compiled the code to capture images, but it can’t read frame from ZED X Mini GMSL2 connection.
Please see the error in the picture.

Is there anyway to capture raw image for calibration other than OpenCV? Or how to fix the reading with OpenCV?
Thank you

Hi @linh.nguyen
you can use the code of the image capture tutorial:

  • replace sl.VIEW.LEFT with sl.VIEW.LEFT_UNRECTIFIED
  • add a new line to retrieve the right image:
    zed.retrieve_image(image_right, sl.VIEW.RIGHT_UNRECTIFIED)
  • use the write function to save the images
