I’d be happy to help clarify the limitations and capabilities of the Jetson AGX Orin series.
1. Is the limitation of 6 image sensors due to hardware?
The limitation of 6 image sensors is not strictly a hardware limitation, but rather a combination of hardware and software constraints. The Jetson AGX Orin series has 4 CSI (Camera Serial Interface) bricks, each of which can support multiple virtual channels. However, the number of virtual channels that can be supported concurrently is limited by the hardware’s ability to process and multiplex the camera data.
The Orin AGX has a similar architecture to the Xavier AGX, with 4 CSI bricks that can be configured in various lane configurations (x4, x2, or x1). However, the Orin AGX has a more advanced ISP (Image Signal Processor) that can support more virtual channels.
2. Does the Orin AGX have the same architecture for the CSI Bricks as the Xavier AGX?
Yes, the Orin AGX has a similar architecture to the Xavier AGX, with 4 CSI bricks that can be configured in various lane configurations. However, the Orin AGX has some key differences:
- The Orin AGX has a more advanced ISP that can support more virtual channels.
- The Orin AGX has a more flexible lane configuration, allowing for more combinations of x4, x2, and x1 lanes.
- The Orin AGX has improved camera interface support, including support for more camera formats and resolutions.
3. What are the available aggregators besides GMSL?
Besides GMSL (Gigabit Multimedia Serial Link), there are several other aggregators that can be used with the Jetson AGX Orin series:
- FPD-Link III (Flat Panel Display-Link III): a high-speed interface for connecting cameras and displays.
- LVDS (Low-Voltage Differential Signaling): a high-speed interface for connecting cameras and displays.
- MIPI CSI-2 (Camera Serial Interface 2): a high-speed interface for connecting cameras.
- SLVS-EC (Scalable Low-Voltage Signaling with Embedded Clock): a high-speed interface for connecting cameras.
It’s worth noting that the choice of aggregator will depend on the specific requirements of your application, including the type of cameras you are using, the resolution and frame rate of the video streams, and the distance between the cameras and the Orin AGX module.
Working around the 6 camera limitation
As you mentioned, virtual channels can be used to work around the 6 camera limitation. By using an aggregator, you can connect multiple cameras to a single CSI brick, and then use virtual channels to multiplex the camera data. This allows you to support more than 6 cameras concurrently.
However, it’s worth noting that using virtual channels and an aggregator will add complexity to your system, and may require additional software and hardware development. Additionally, the performance of the system may be affected by the use of virtual channels and an aggregator, so careful testing and validation will be required to ensure that the system meets your requirements.
