@dangal 你已经搞成了。 由于你只在i2c-30上接入了一个，因此只识别到了一个相机。其他i2c 31-35都报了读取寄存器错误，这是正常的。

@veye_xumm 好的，感谢

@zang 相机是支持这个分辨率配置的。你的整个操作报什么错误吗？ 可以用mv_mipi_i2c.sh脚本读取一下相机实际roi确认是否已经配置到camera里面。 另外300不利于对齐，你可以试试304

@skysplitter It is recommended that you turn off the 3D denoise and wdr features if you have a relatively fast moving vehicle in your usage scenario. This is because these two features essentially use two frames of data to calculate. 2d denoise can be turned on.

@vitob said in NVidia Jetson Jetpack 6 support?: In the meantime, can you help explain this question on tegra-camera.ko and v4l2-core/*.ko? Why they needs to be updated and where can I find the source code of them? Once updating them using the veye release .ko, will that affect other cameras (for example, I want to port/develop driver for another sensor myself)? Thanks. These driver changes add support for RAW8 RAW10 RAW12 data types on the one hand, and externally triggered modes on the other.

@otca I will continue discussing that issue with you in the other post.

Did u solve it ??? Iam using jetson nano B01 Devkit I have exact problem like u : [image: 1725393713979-1b047cd6-2fcf-43d5-a62e-ded2c5ab38de-image.png]

@veye_xumm 感谢感谢

@leibnitz 是的，qv4l2拿到图像，进行转码，搬移，预览，做了很多工作。整个pipeline的冗长和软件效率的问题导致预览无法达到相机的输出能力。 用下面https://wiki.veye.cc/index.php/Mv_series_camera_appnotes_4_jetson/zh#.E5.B8.A7.E7.8E.87.E7.BB.9F.E8.AE.A1 7.3.2 帧率统计 的命令来统计一下实际相机输出的帧率。

@lin 相机触发模式出图和流模式出图，对你的程序接收图像而言，没有区别啊！

@scroll 您好，我使用其他的相机，遇到了和您一样的问题，请问您解决了吗？

@alex_ai said in IMX462M pixelformat on RPi5: I need wait for clear sky to test and provide feedback Finally tested, for gain value 20 it is looks pretty same with color sensor with ISP, but background no so black as for color sensor. For me this issue resolved, attached examples to compare (10 seconds stacks) IMX462 mono [image: 1723360275505-imx462m_small.jpg] IMX462 color with ISP [image: 1723360306335-imx462c_small.jpg]

@oleg This link provides a reference for workarounds to this problem. Camera menu appears on VEYE-MIPI-IMX327S However, I'm curious why this issue occurs so frequently on your end. Could you please measure the SCL level using an oscilloscope? When the VEYE module is not configured, SCL should always remain high. If there are frequent and continuous level changes, it indicates that the system is operating on the I2C bus.

@egor Sorry, I think the accurate way to do this now is still through an external sensor like a photocell.

@carrot said in Can't select 25Hz framerate on MIPI IMX462: Please try this: sudo ./veye_mipi_i2c.sh -w -f videoformat -p1 PAL -b 9 gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 !

@veye_xumm 请问FPGA和RK3588直连，没有I2C，怎么在设备树里添加相机？相机驱动又该怎样处理？

@nb 您好，我遇到了类似的问题，请问一下您的解决方案就是将4.6的opencv更换成4.2的opencv吗？
