Object location on grid

[jrossy_1191]

I am currently trying to develop a program where the aim is to have a 3x3 grid drawn on a piece of paper which is in view of a camera. The lab view program should be able to read the location of the grid squares to be used in the next step. An object will then be placed in one of the grid squares by a robot. I then want my lab view program to firstly 1) Find the object. 2) Use its location to determine which grid square the object is in. 3) Send that information to another robot (e.g. tell the robot the object is in grid square 3.) 

Any ideas on how to approach this or examples of similar things being done. I am quite new to Labview.

Either (try to) detect the grid lines or the grid squares.

First step will probably be to do a threshold separating the grid lines from the background...

Next step is typically some analysis with calipers or blobs...

The result should be coordinates...

The object, once detected (also usually a threshold and some analysis), has coordinates...
