Camera calibration

Hi all, I am trying to calibrate the stereo camera and have several questions. 1. I saw the calibration scripts in the tutorial( https://github.com/realizator/stereopi-tutorial ) and it seems like storing the calibration result into many executable files, but I would need a yaml file to feed into a ...

Re: Receive livestream on another Linux machine

Hi Eugene, I tried to replace the "fpsdisplaysink" with "autovideosink" as you suggested, but the result and error messages are the same as before. I also tried different sink options after referencing the GStreamer website, like udpsink and fakesink; the udpsink option gave an error of message too ...

Re: Receive livestream on another Linux machine

Hi Eugene, I already followed the steps described in the wiki (setting up the UDP client address and running the GStreamer command). The result was included in the last last respond( the one with content of the terminal info). Basically, the result is I could not receive livestream by using the GStr...

Re: Receive livestream on another Linux machine

Hi Eugene, I don't have a custom script for the stereoPi; now I just run GStreamer on Nano to see whether it can livestream through UDP. So I follow the step you sadi; ssh to stereoPi and stop all scripts. After that, I ran the GStreamer command on Nano but still no live videos pop out. Then, I rest...

Re: Receive livestream on another Linux machine

Great. So now I am able to access the stereoPi through the SSH with my nano and even able to see the livestream with a browser. I try to set up the nano with the gstreamer like the one on wiki for Mac. However when I run this on the command line: gst-launch-1.0 -v udpsrc port=3000 buffer-size=300000...

Re: Receive livestream on another Linux machine

Hi Eugene, I probably would not use a router as both the stereoPi and Nano are mounted to a small robot. I know how to set the static IP address for the Nano but how to do it for the StereoPi with SLP image? Via admin panel or SSH? I have one more question about the admin panel: I see an option "USB...

Re: Receive livestream on another Linux machine

Hi Eugene, Thank you very much for your reply. So I might try to stream it through the network. Can this network be a local network, like I just connect the StereoPi and my Linux machine through the LAN cable? My end goal is to stream the frames captured by stereoPi to the Jetson Nano doing a real-t...

Receive livestream on another Linux machine

Hi, I am new to StereoPi. As I go through the SLP image tutorial in the wiki, there are parts to introduce how to receive Livestream on windows and Mac, but I wonder how to receive Livestream on another Linux machine. And is it possible to make it become a standard USB camera? Thanks in advance and ...
