use two kinects to track user skeleton

[JustinK]

 i want to use two kinects two get robust skeleton joints ,now i have the questions below:

if two kinects can used on one computer ,what requirements shall i meet?

if i have to use two computer ,is there any synchronization mechanism openni can provide?

or i just need to write the synchronization code by myself?

thanks for any reply.

Hi,

In order to get the skeleton from two kinects in the same computer you need to enumerate the production nodes of the user generator

context.EnumerateProductionTrees (XN_NODE_TYPE_USER, NULL, list, NULL);

You will see (or at least this what is happening to me) that you will get 4 nodes.

To get the skeleton from the two kinects:

xn::NodeInfoList::Iterator nodeItUser  = user_generator_nodes.Begin();
xn::NodeInfo info1 = *nodeItUser;
_context->CreateProductionTree(info1);

//for the second kinect

nodeItUser++,nodeItUser++,nodeItUser++;
xn::NodeInfo info2 = *nodeItUser;
_context->CreateProductionTree(info2);

Hope this helps,
