Vision Kalman Tracking Robot

[Multifunction_DAQ]

Dear All, 

                 I am looking for any example or code share to apply kalman filter to track object in Labview.  My application is to track the object in the air and move robot toward the object. Camera is fixed on the wall.

Some of my questions are ,

1) I am using vision assistant , color tracking example it is very useful, I have made some modification acquiring video from webcam but  after object is identified How I can find its coordinate using Labview  ?

2) How to apply kalman filter on the image using labview to track object path  in LabView any example ?

3) how transform coordinate of object to the robot so it follow the object ?

I am stuckup in this problem for a week ,I read the reference manual and other material but no success in LabVIEW.

Looking forward to your help.

Hi Multifunction_DAQ (nice name),

In response to your questions see the following:

1. The example you mention already determines the coordinate of the center of the ball. That is how it is overlaying the circle on the display. The Vision Assistant Express VI is outputting the Center X and Y coordinates of the ball it is tracking.

2. I could not find an example of using a Kalman filter to track an image in LabVIEW; though, using the Robotics Toolkit there are a few examples (not exactly what we are looking for but may be helpful).

3. I could not help you here as it is likely very specific to the robot. It would probably require a fair bit of algorithm development so your best bet would be to try and find an example (in LabVIEW, C++, or otherwise) and try and build off of that.
