Multi-Camera Network issues #103

Closed muella91 closed 4 years ago

muella91 commented 4 years ago

Hello,

I have two questions:

  1. Since I do not have enough hardware available (but this is very powerful), I would like to run a camera node and the master on a computer for multiple-camera pose tracking. I did not get totally how to do this, I read I have to change the container name, but did not get it how to do it.

  2. I don't understand what I have to customize in the ntp.config file.(https://github.com/OpenPTrack/open_ptrack_v2/wiki/Time-Synchronization). I dont get the description

For other nodes to sync to this master, and if the master is not online, comment out the first external server. Please note that this assumes a 192.168.100.X network (if necessary, change the broadcast to match the network).

Thanks for your help!

To clarify question number 1: Do you want to run multiple imagers from a single computer, with pose tracking running for each of them? This may not perform well. Let me know if I've understood this correctly.

For NTP configuration: you should uncomment (remove the #) of the first server: server 0.ubuntu.pool.ntp.org and change the last line to match your IP address so that it reads something like ###.###.###.255

I agree that the instructions in this section are confusing, so I will be updating them as I work on other documentation!

Thanks for your answer. I made it to set up the NTP server/client connection and start the calibration. Few questions on that:

  1. To my last question: I want to run the central node and one sensor node on one PC. The Laptop has an i7-7920 with two GeForce GTC 1080 GPUs and 64GB RAM. We are booting from a USB, if we see that the system works for us, we will buy Jetson HW.

  2. When I run the NTP client, it often doesnt work and shows pc1.loca with the refid .INIT.. Does the INIT mean it just need more time for the setup?

  3. edit: Solved it. I did not see the messages that the cameras are added to the tree, because of the other messages "Checkerboard detected..." moved those messages really much up in the terminal.

Glad you got the calibration question sorted. Did your NTP sync work? It takes ~10-20 minutes for the results of ntpq -p to show the validation.

Were you able to resolve your NTP issues?

Based on your questions in other threads, I'm guessing you have your system set up so I'll close this now. Feel free to re-open if you still have questions about setting up a multi-camera system!
