Object Tracking VI with VDM Bounding box error

[venus.luong]

Hi! I'm really new to Labview and have only started a week ago.

So I really need help making this code that will take 3 objects, track their x,y coordinate, create a time-taking function, and output their velocity and rotation.

In order to tackle this, I used Labview's object tracking and modified it with Labview's histogram program to have it record a first picture and boundaries on the object then use the object's rectangular coordinates as a base for the bounding box. I am using the traditional mean shift device at the moment. However, as shown by the error in the picture, I have an "invalid bounding box passed" error. I am not sure how to fix this and would appreciate any examples or advice.

Thank you so much!

Sincerely,

Venus Luong

Ok, so I actually solved the issue. Now, I'm trying to fix this part which I don't really understand. I'm trying to have a "n-matrix" and then I want to put the coordinates into the array and have it update each row or element inside the x and y arrays. I'm stuck. Please if anyone can help me!

How did you solve the invalid bounding box issue?

Thanks

I got rid of the bounding box error by increasing its size; at least on the errors related to the bounding box is its size, there appears to be a minimum. Not sure if the minimum is image dependent or not.
