UNSOLVED OpenCV VEYE-MIPI-IMX462 Demo Sketches result in error

jakobvol

Hello,
I tried very hard to get the YEYE-MIPI-IMX462 working with openCV on a raspberry pi4. But not even the example VEYE-OpenCV sketches are working my configuration.

I want to explain my problem and system as detailed as possible:

My installation steps:

wget https://github.com/veyeimaging/raspberrypi_v4l2/releases/latest/download/raspberrypi_v4l2.tgz
tar -xzvf raspberrypi_v4l2.tgz
cd raspberrypi_v4l2/release/
chmod +x *
sudo ./install_driver.sh veyecam2m

sudo apt-get install gstreamer1.0-tools
sudo apt-get install libx264-dev libjpeg-dev
sudo apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libgstreamer-plugins-bad1.0-dev gstreamer1.0-plugins-ugly gstreamer1.0-tools gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-plugins-good gstreamer1.0-plugins-bad

sudo apt install python3-opencv
pip install opencv-python

I already tried:

pip uninstall opencv-python
sudo apt install python3-opencv

like it was written in that post:
https://forum.veye.cc/topic/274/opencv-无法找到摄像头/9?_=1685312066853
But then the line

import cv2

causes an error, because it is not found

At least the Camera works:
Veye Cam IMX462 Camera works with VLC
also over Gstreamer with following Command:

gst-launch-1.0 v4l2src io-mode=dmabuf device=/dev/video0 ! "video/x-raw,format=(string)UYVY, width=(int)1920, height=(int)1080,framerate=(fraction)30/1" ! v4l2convert capture-io-mode=dmabuf output-io-mode=dmabuf ! autovideosink sync=false -v

I tried already 32bit and 64bit Pi OS (Bullseye)

But when I try out the openCV examples on Github
https://github.com/veyeimaging/raspberrypi_v4l2/tree/main/samples/opencv/yuv_camera
then I get following errors:

I also tried to write a pipeline with Gstreamer to OpenCV
with pipelines like following:

cap = cv2.VideoCapture("gst-launch-1.0 v4l2src device=/dev/video0  ! video/x-raw,format=(string)UYVY, width=(int)1920, height=(int)1080,framerate=(fraction)30/1 ! videoscale ! video/x-raw,width=640,height=480 ! videoconvert ! video/x-raw, format=(string)BGR ! appsink", cv2.CAP_GSTREAMER)

But I was not able to get the Veye Cam IMX 462 in OpenCV working.
I was spending the whole Weekend trying to get this working, but I have no further Idea what to try. Please help me :))))

Thank you very very much in advance!

Hi,
At the current time, I don't think there's a need for a complicated installation of gstreamer and opencv.
I am using the Raspberry Pi OS with desktop and recommended software version of pios downloaded from the official Raspberry Pi website.
After installing the camera driver and running sudo apt install python3-opencv, I am able to run the samples without any issues.

Hm weird. I thought I tried that already. I will check it again next weekend, when I have time.

But Thanks a lot for your reply :))

@jakobvol Sure, you give it a try and let me know if there are still any issues.
