@lin 你好，现在我们并没有使用rk3588内部的isp的经验。不好意思。

@newleaf
Looking at the image you sent, I do think it's an IR cut issue.
Could you tell me which aespeed-related command you used to reproduce this phenomenon?

@etherealhorizon said in IMX 287 opencv python多线程多相机硬触发帧率下降:

最后是用python多进程为每个相机分别subprocess运行v4l2-ctl命令行然后读取--stream-mmap --verbose的时间戳

这个时间戳不够准确，如果你的算法对事件准确性要求不高，也可以先这样用。

还想请教一下怎么做real time binning，就是实时地将2x2或者4x4的像素值求和再保存，我们的c水平比较烂哈哈。

这个我们也缺乏实际经验。不好意思。

@lin 不客气。

@veye_xumm 解决了,dphy4不支持4lane

客户已解决。是kernel配置中关于rkcif的配置原因。

@leo12757
你好，抱歉这两天比较忙，我给一个大体的思路您可以试一下。
install_driver.sh在安装驱动的时候，做了如下两处更改，您可以手动去掉，然后重启系统后再测试一下。

Add gpu=256M to ${CONFIG_FILE}，CONFIG_FILE="/boot/firmware/config.txt" or CONFIG_FILE="/boot/config.txt"

echo "Add cma=128M to /boot/cmdline.txt "

@veye_xumm 对的，所以我感觉很奇怪。 下面是我修改的install_driver.sh
echo "Add cma=128M to /boot/firmware/cmdline.txt "
echo "--------------------------------------"
sudo sed 's/cma=128M//g' -i /boot/firmware/cmdline.txt
sudo sed 's/[[:blank:]]*$//' -i /boot/firmware/cmdline.txt
sudo sed 's/$/& cma=128M/g' -i /boot/firmware/cmdline.txt
echo "Installing the $driver_name.ko driver"
echo "--------------------------------------"
sudo install -p -m 644 ./driver_bin/$(uname -r)/$driver_name.ko /lib/modules/$(uname -r)/kernel/drivers/media/i2c/
sudo install -p -m 644 ./driver_bin/$(uname -r)/$driver_name.dtbo /boot/firmware/overlays/
sudo /sbin/depmod -a $(uname -r)
echo "reboot now?(y/n):"

谢谢！

@veye_xumm 可以了，非常感谢

@sqf121 不客气。

@frankerooney
Since the driver has been probed, I assume that the hardware connection is fine.

@frankerooney said in No output from IMX462 module:

The program just then sits there, producing no output to stdout. I've waited 20 minutes or so, nothing produced.

For v4l2 mode, veye_raspivid cannot be used .

Please try part7——use qv4l2 first.

@veye_xumm 好的，已解决

@veye_xumm 好的，已解决

@atboy 通过邮件联系吧。sales@csoneplus.com

@023 就是最常用的1.25间距白端子。

@egor Sorry, this feature is not supported right now.

@张志伟 按照我我们wiki上步骤去调用yavta存图一定是可以的。你把你用的命令发出来我看看。

@veye_xumm 解决了，重启后，可以了

@newleaf said in Recommendation to reduce startup latency for IMX327S:

For our system, we utilize 940nm IR lighting at night that is triggered by motion. I noticed that there is a 1-3 second period for the camera to adjust each time if we start streaming when the lighting is activated. The first few images are washed out until AE kicks in. What's the recommended approach to eliminate this latency and the initial washout? Should we explore manual exposure and gain? Thx!

You can try configuring aespeed first, and then try manual mode if that doesn't meet your needs.
