Hi all,
I'm trying to retrieve a personData from bodyTracking module using R200 camera.
I have a while senseManager acquire frames loop and in it I'm using a personTrackingData ptd and querying it to get the Person instance:
...
...
...
while (sm.AcquireFrame(true).IsSuccessful())
{
Thread.Sleep(1000);
// ptm is a PXCMPersonTrackingModule instance
PXCMPersonTrackingData ptd = ptm.QueryOutput();
PXCMPersonTrackingData.Person p = ptd.QueryPersonData(PXCMPersonTrackingData.AccessOrderType.ACCESS_ORDER_BY_ID, 0);
// Get the data
tracker.numberOfPeople = ptd.QueryNumberOfPeople();
tracker.trackingState = ptd.GetTrackingState();
person.presonID = p.QueryTracking().QueryId();
person.pointInfo = p.QueryTracking().QueryCenterMass().world;
printData(person, tracker);
// Resume next frame processing
sm.ReleaseFrame();
}
// Clean up
sm.Dispose();
...
...
...
On the marked line I get an unhandled exception of type 'System.AccessViolationException' occurred in libpxcclr.cs.dll error.
(Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.)
I read a bit in this issue and saw that it could be caused by using 2 instances of SenseManagers running and using the same resources from 2 threads.
I don't know what it's have to do with QueryPersonData() function I call.
Anyone has an idea that can help me solve this problem?
