ball tracking w/ camera

[sloteera]

Could you make an combination between Color Location and Find Geometric Shapes to prevent any confusion of the camera between ball and target?

If you consider that the floor is green and ball is white, you'll have a good enviroment to use these two functions.

I tryed it... but I think that I hadn't success because we are use our camera with mirrors associated!!!

Our team has been successful in identifying a white ball against a green background. I recommend a two-level test (meaning you will have to create 2 scripts in VA): 1- Identify a round object using appropriate steps in VA, 2- another script to identify the appropriate range of color that would be the official ball color for the competition. This methodology would at least increase your chance of finding THE ball, instead of just another round object in the playing field.

We have written a ball tracker in VA, but can't seem to get it to work on the robot (C++) It worked once (we were seeing numbers come out) but hasen't since then. also writing an image to file does not work, Is there a way to stream the binary image after particle analysis?
attached is the scr, some sample images, and the C++ code (adapted from 2010VisionDemo, added in exported VA C code)
