OpenCV. Crop and change resolution to increase FPS
-
Hello! The example on OpenCV is very slow on RPI4 and RPI3B+ according to allocate memory. Not important which relolution I choose, because example copy full hd resolution. It's a big problem, I think.
-
You're right. The demo does have this problem.
We now provide the v4l2 driver mode.

Whether it is helpful to the application of opencv, please refer to it.In addition, the camera output is now in UYVY format by default. Will it be helpful to the application of opencv if I YUYV format ?
-
@veye_xumm Changing to YUYV may be helpful for some programs that expect a grayscale image first. I noticed a new firmware version has an option for changing to YUYV. Is it already possible to enable this with an i2c command?

@veye_xumm Thanks, I forgot to update the script from Github

@veye_xumm Is it possible to switch to YUYV on VEYE-MIPI-327 ?

@jk
hi,VEYE-MIPI-327 do not support this feature.
VEYE-MIPI-327S support and it is our recommended model for the future.

@veye_xumm
Are there plans to implement resolution at 720p and higher framerates (60fps) as with the imx307? -
@mk No such plan, this cannot be supported. Sorry.
