RAW-MIPI-SC132M camera working in raspberry pi 5. Cannot be configured to work with the libcamera2 and opencv libraries
-
@alex_ai
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confusion, in previous time you guided me to install custom libcamera for veye_mvcam driver and seems like this step is outdated (but I'm still using libcamera).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 -
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 -
@veye_xumm
I got the title wrong - I meant Picamera2. I need to start working in Opencv first.~ $ rpicam-hello [3:42:19.883111801] [3703] INFO Camera camera_manager.cpp:330 libcamera v0.5.2+99-bfd68f78 [3:42:19.894406703] [3706] INFO RPI pisp.cpp:720 libpisp version v1.2.1 981977ff21f3 29-04-2025 (14:13:50) [3:42:19.895982049] [3706] WARN CameraSensorProperties camera_sensor_properties.cpp:499 No static properties available for 'mvcam' [3:42:19.896044820] [3706] WARN CameraSensorProperties camera_sensor_properties.cpp:501 Please consider updating the camera sensor properties database [3:42:19.899758099] [3706] ERROR IPAProxy ipa_proxy.cpp:185 Configuration file 'mvcam_mono.json' not found for IPA module 'rpi/pisp' [3:42:19.899815776] [3706] ERROR IPARPI ipa_base.cpp:152 Could not create camera helper for mvcam [3:42:19.899835354] [3706] ERROR RPI pipeline_base.cpp:814 Failed to load a suitable IPA library [3:42:19.899850764] [3706] ERROR RPI pisp.cpp:947 Failed to register camera mvcam 10-003b: -22 Made X/EGL preview window ERROR: *** no cameras available *** -

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.

@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.

@sheko
As I see your standard camera parameters are: 1080x1280 120fps
And as it configured in python script for first step try:cap = cv2.VideoCapture('v4l2src device=/dev/video0')if still failing try with passing parameters to gstreamer:
cap = cv2.VideoCapture('v4l2src device=/dev/video0 ! video/x-raw,format=UYVY, width=1080, height=1280,framerate=120/1 ! videoconvert ! video/x-raw,format=GRAY8 ! appsink sync=1')or from command line to check if gstreamer works without python
gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=UYVY, width=1080, height=1280,framerate=120/1 ! videoconvert ! video/x-raw,format=GRAY8 ! appsink sync=1if still failing try RAW8 format
gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=RAW8, width=1080, height=1280,framerate=120/1 ! appsink sync=1if still failing, can't help, I don't have this sensor.

It turns out the manufacturer is ignoring requests for help. Only kind and caring people are helping... The problem remains unresolved.

@sheko Sorry, I just got back from the Chinese New Year holiday. Regarding using the RAW-MIPI-SC132M on the Raspberry Pi 5, I suggest you primarily refer to this document. It covers driver installation, how to use the V4L2 mode, and methods for previewing using OpenCV.
