Very good! thanks

Great job! Really impressive! How much different would it be with a d435i and with Jetson Nano? Do you have any ideas? It is ridiculously messy to work with these camera. Don't really get why!

Thank you for making this video. Still really helpful, despite a few things being different since it was first published.

What are the limitations of running RealSense/OpenCV on a Raspberry Pi 4? I've seen some really poor frame rates (less than 5) on i5 8GB systems, so I'm curious to see how this video's setup performs.

Hi @ACROBOTIC, Why does my comment gets removed? I was seeking for help to understand the problem during the installation procedure

would this work with a 16gb sd card? Update: You can install the SDK and be able to successfully install librealsense and run realsense-viewer but you will be at 100% usage and will have no free space to add the python wrapper or anything else. Can confirm that you will need a 32GB sd card

For now, I've only tried the D435, but as the communication protocols are similar, the Python code *should* work with the rest of the line. At the very least, you can see if the devices are recognized by the realsense-viewer, and then take it from there. HTH!

are there other viewers for intel realsene or is this the only one? i would love to have a camera, raspberry pi and a small screen to measure depths, however i dont need the viewer gui, is it possible to just have the raw depth video feed displayed on screen or must you use the realsense viewer ??

You can, one limitation is on the USB speed. Notice that I connected the camera to USB 3 ports. Intel announced a while back support for USB 2 (which are the only option on a Raspberry Pi 3B+): www.intelrealsense.com/usb2-support-for-intel-realsense-technology/ But, you'll have to trade off the smaller bandwidth for image quality. HTH!

If you connect monitor to the screen it will show the realsense-viewer. Vnc viewer uses virtual tech to simulate monitor to operating system. Only way to solve this is to update glx drivers on raspi. Eventually we shifted to Jetson platform and couldn't reproduce the problem. Will update you with the issue link if we find it.

It depends on the system's architecture of the other boards. Since the libraries have been compiled for the SoC on the Pi, you'll need to recompile the source code for other ones. If it's the same architecture (e.g., armv7) then it shouldn't be too bad. Best of luck!
