Still rigid body are not always detected,

[martinv]

Hi,

I have 2 rigid bodies defined, my problem is that they are not tracked by TrackingTool until I move one of them!

One has 3 markers (actually it is the wand)
The other one has 4 markers.
When I reproduce the issue, both rigid body are about 10 cm apart.

Here are the steps I do to reproduce the problem

-I use TrackingTool 2.5.0
-One rigid body has 3 markers.
-The other one has 4 markers.
-I start the TrackingTool
-I load the project file (.ttp) which contains the rigid body.
-I go in the Project Explorer and select my rigid body
-I open the Trackables->Real-Time Info window
-The problem is that none of the rigid body are tracked.
If I physically hide one of the markers and then unhide it (with my hand), then TrackingTool tracks correctly the 2 rigid body.

Is there an option to "force" TrackingTool to track without having to move the rigid bodies ?


Additional note: If I only have 1 rigid body in front of the camera (before starting TrackingTool), then the rigid body is tracked correctly.

Note: I have the same issues when I use the TrackingTool API.

thank you,

Martin

Hi,

I have reported the problem when I was using
Properties->Advanced->Point Cloud set to "Engine v1.0"


If I used the "Engine v2.0", then I cannot reproduce the problem.


The problem I have is that under other circumstances (in a dark environment), the Engine v1.0 helped me to improve the tracking.


In bright environment it seems Engine 2.0 is the best one.

So it is difficult to determine which engine to use, I will have to perform more tests to take the algorithm that best work.

Does anyone can share experience on which engine they have choosen ?

thank you,

Martin
