Streaming from two cameras

PR1 — Thu, 16 Mar 2017 14:22:05 GMT

Hello

Has anyone streamed and displayed data from two cameras simultaneously?

I am using the Sr300 .

Could you please give me a heads up if anyone has any knowledge about it?

With the official RealSense SDK, you can attach multiple cameras to the same PC but only access one at a time. The open-source Librealsense SDK, which is approved by Intel, does support multi-camera capture though.

Expert developer Andre Carlucci said "Librealsense doesn't provide hand tracking out of the box. You will have to get the streams and use it together with OpenCV for that. Here is one example on github":

Thank you for you reply.But I am getting an error when I try to use the Project from github in the real sense library.Has anyone tried it?

I am getting an error saying there is no reference of the glfw library however I have checked that it is referenced .

Any help would be appreciated.

Also I wanted to ask even if we use two sense Managers for two cammeras in the session and then enumerate the devices and create individual capture Managers for both it would not stream simultaneously without using libreal sense?

Cheers and thank you

It looks as though you should include a line in your script that installs the glfw library:

sudo apt-get install libglfw3-dev

In regard to the question about two Sense Managers: usually, creating two Sense Managers fails to work out well. I believe that if a duplicate Sense Manager is detected when one already exists then the duplicate is destroyed.
