UNSOLVED RAW-MIPI-SC132M camera working in raspberry pi 5. Cannot be configured to work with the libcamera2 and opencv libraries

alex_ai

Hi @sheko, I had same problem with RPi 5, did you build and install libcamera from veye github repository? For some reason it has config json file only for RPi 4.

First step try run it with uncalibrated json :

rpicam-still --tuning-file /usr/local/share/libcamera/ipa/rpi/pisp/data/uncalibrated.json -t 0

Path may be different, if failed to load json file - try to find valid path.

if video opened - we need just put to same folder mvcam_mono.json (or add to libcamera source code, update meson.build and rebuild + reinstall )

and check if rpicam-hello or rpicam-still works without tuning file

I attached my current config (rename it to json) but it adopted for night sky and you need fix in json file section : exposure_modes . normal, copy it for example from se327m12.json
mvcam_mono.txt

RAW-MIPI-SC132M does not support libcamera, nor software based on libcamera. Direct invocation via the v4l2 API is required.

Hi @veye_xumm, sorry for confusion, in previous time you guided me to install custom libcamera for veye_mvcam driver and seems like this step is outdated (but I'm still using libcamera).

@Sheko try another pipeline in openCV:

v4l2src device=/dev/video0 ! video/x-raw,format=UYVY, width=1920, height=1080,framerate=30/1 ! videoconvert ! video/x-raw,format=GRAY8 ! appsink sync=1

@alex_ai

command not found(((

~ $ v4l2src device=/dev/video0 ! video/x-raw,format=UYVY, width=1920, height=1080,framerate=30/1 ! videoconvert ! video/x-raw,format=GRAY8 ! appsink sync=1
bash: v4l2src: command not found

I got the title wrong - I meant Picamera2. I need to start working in Opencv first.

@sheko
This is pipeline which need place to openCV instead:

cap = cv2.VideoCapture('/dev/video0')

to run it from command line you need use gstreamer, try :

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=UYVY, width=1920, height=1080,framerate=30/1 ! videoconvert ! video/x-raw,format=GRAY8 ! appsink sync=1

@sheko please update pipeline with your camera parameters (width, height, framerate). I just copied mine.

Sheko

@alex_ai How to do this?

@veye_xumm said in RAW-MIPI-SC132M camera working in raspberry pi 5. Cannot be configured to work with the libcamera2 and opencv libraries:

Требуется прямой вызов через v4l2 API.

Direct call via v4l2 API? What does that mean? Give an example for Python.
