Do not use this image.
Use this one：
ROC-RK3588S-PC_Ubuntu_v1.0.4b_221226_veyecam2m.img -
It works now! Thank you.
Maybe you can update the documentation. https://wiki.veye.cc/index.php/VEYE_CS_Camera_on_Firfly_Boards
For me it was not clear and I just downloaded the latest image for RK3588S which is v1.0.6f

Hi @veye_xumm
On RK3588S with opencv I only get slow FPS reading from IMX462 of around 15 FPS. The same code on RaspberryPi can read with 30FPS.
Here is what I tried:
1.)
camera.open( "v4l2src device=/dev/video0 ! video/x-raw, format=(string)NV16, width=(int)1920, height=(int)1080,framerate=30/1 ! videoconvert ! appsink'", cv::CAP_GSTREAMER);Only 11-13 FPS
2.)
camera.open( "v4l2src io-mode=dmabuf device=/dev/video0 ! video/x-raw, format=(string)UYVY, width=(int)1920, height=(int)1080 ! appsink", cv::CAP_GSTREAMER);Can open camera but can not read frame
3.)
camera.open(0, cv::CAP_V4L2); camera.set(cv::CAP_PROP_FRAME_WIDTH, 1920); camera.set(cv::CAP_PROP_FRAME_HEIGHT, 1080);Can open camera but can not read frame
Here is the output of dmesg

Have you tried these samples here?

Yes please see my examples.camera.open( "v4l2src io-mode=dmabuf device=/dev/video0 ! video/x-raw, format=(string)UYVY, width=(int)1920, height=(int)1080 ! appsink", cv::CAP_GSTREAMER);Does not work. I can open the camera but the frames are always empty.

I did some more tests and tested all the examples from https://github.com/veyeimaging/rk35xx_firefly/tree/main/linux/samples/opencv/veye camera
Files 1-3 do not work. No frames are shown. Only v4l2_opencv_show4.py works but it only reads with 15 FPS.
Can you confirm that the python opencv examples 1-3 work with ROC-RK3588S-PC and IMX462 ?
-
Hi @veye_xumm
Do you know why UYVY does not work from the examples? -
@veye_xumm Please help.
v4l2_opencv_show1.py
v4l2_opencv_show2.py
v4l2_opencv_show3.pyDo not work with ROC-RK3588S-PC and IMX462.
-
@natzguk
I'm sorry for not replying earlier.
To be honest, we are not very familiar with OpenCV. I believe the low frame rate is due to the software-based UYVY to preview data format conversion, which involves CPU processing for each pixel, leading to inefficiency.
I will verify the samples and your script as soon as possible. -
Only
format=NV12(v4l2_opencv_show4.py) works with OpenCV but it requiresvideoconvertwhich is very slow.I want to use
format=UYVY(v4l2_opencv_show2.py) but it does not work with
ROC-RK3588S-PC and IMX462. I believe it is a problem with the driver for ROC-RK3588S-PC. The same code withformat=UYVYworks with Raspberry PI 4. -
Did you have any chance to check the samples
v4l2_opencv_show1.py
v4l2_opencv_show2.py
v4l2_opencv_show3.pywith ROC-RK3588S-PC and IMX462?

The same code with format=UYVY works with Raspberry PI 4.I apologize for the delay in responding to your question. In fact, as mentioned here, the VICAP module of RK3588 does not support outputting the UYVY format, so please use the NV12 format instead.
Actually, I think using the NV12 format is a good choice.It will not lead to a decrease in system efficiency.@natzguk said in ROC-RK3588S-PC and IMX462:

with ROC-RK3588S-PC and IMX462?Indeed, as you said, only sample4 works correctly. These samples are just collected examples of common ways to use OpenCV to access the camera, provided for customers as a reference.
As mentioned before, our expertise in OpenCV development is not extensive.videoconvertis indeed an issue. I believe the internal data format of OpenCV is RGBA, and regardless of whether you use UYVY or NV12, conversion is needed. -
If I use NV12 as described in sample4 I can only read frames with max 15FPS from the camera. This will not work for our application.
Can you show me an example which can read frames with 30FPS?
-
@natzguk I believe the key issue lies in videoconvert and the display, which has low efficiency. You can refer to our GStreamer for previewing.

@veye_xumm
I am not talking about previewing the frame. I am talking about simply reading the frame. No processing.Here is the example with sample4:
import numpy as np import cv2 as cv import os import time cap = cv.VideoCapture('v4l2src device=/dev/video0 ! video/x-raw, format=NV12, width=1920, height=1080, framerate=30/1 ! videoconvert ! appsink', cv.CAP_GSTREAMER) if not cap.isOpened(): print("Cannot capture from camera. Exiting.") os._exit(0) last_time = time.time() frame_count = 0 while True: ret, frame = cap.read() if not ret: break frame_count += 1 this_time = time.time() if this_time - last_time >= 1.0: fps = frame_count / (this_time - last_time) print(f"FPS: {fps}") last_time = this_time frame_count = 0 cap.release() cv.destroyAllWindows()Simply reading the frame is currently only getting 15 FPS on ROC-RK3588S-PC. I believe this is a driver issue with NV12.
