RealSense camera low framerate issue

Robotics & Edge Computing Jetson Systems Jetson AGX Orin
1

我们在Orin DevKit开发套件上测试使用RealSense D415相机

单个相机连接到USB A口上，使用realsense-viewer程序打开相机，
Color Stream设置为1920x1080@30，Depth Stream默认设置1280x720@30
此时图像帧率是正常的；

当连接两个相机到USB A口时，同时按以上设置打开相机，发现两相机帧率会下降，


可以确定两个相机占用的带宽不会超过10Gbps

这种情况是如何导致的呢，是否与USB A口内部使用USB Hub相关？如何解释和解决呢？

Based on the provided context, I will attempt to provide a comprehensive answer.

The question appears to be related to the Jetson AGX Orin Developer Kit and its compatibility with the RealSense D415 USB camera. Here’s a breakdown of the information:

  • The Jetson AGX Orin Developer Kit is a platform for developing and testing AI and computer vision applications.
  • The RealSense D415 USB camera is a depth-sensing camera that can be used with the Jetson AGX Orin Developer Kit.
  • The question mentions the use of the Arealsenseviewer tool to display the color and depth streams from the camera.
  • The color stream is set to 1920x1080 at 30 frames per second, while the depth stream is set to 1280x720 at 30 frames per second.
  • The question also mentions the use of a USB 3.0 hub and a USB-A to USB-C adapter.

Based on the provided context, here are some observations and comparisons:

  • The Jetson AGX Orin Developer Kit is a more powerful platform compared to the Jetson Orin NX and Jetson Orin Nano modules.
  • The RealSense D415 USB camera is a popular choice for depth-sensing applications and is compatible with the Jetson AGX Orin Developer Kit.
  • The Arealsenseviewer tool is a useful utility for displaying and testing the camera streams.
  • The use of a USB 3.0 hub and a USB-A to USB-C adapter suggests that the user is using a USB-C port on the Jetson AGX Orin Developer Kit to connect the camera.
  • The Jetson AGX Orin Developer Kit has a more comprehensive set of development tools and software development kits (SDKs) compared to the other Jetson modules.

In terms of compatibility, the Jetson AGX Orin Developer Kit should be able to support the RealSense D415 USB camera and the Arealsenseviewer tool. However, the user may need to ensure that the camera is properly configured and that the necessary drivers and software are installed on the Jetson AGX Orin Developer Kit.

Overall, the Jetson AGX Orin Developer Kit is a powerful platform for developing and testing AI and computer vision applications, and it appears to be compatible with the RealSense D415 USB camera and the Arealsenseviewer tool.
