coordinate system

[Emiel]

hello,

I want to place a coordinate system on a point in an image. I am using the IVA coordinate system manager. I am having trouble whit the input 'Origin ID'. I can not find the right format. I have the right coordinates of the origin of my coordinate system but can't translate it to the right format. Can someone help me or give me a good alternitive? I have attached an image of the IVA coordinate system manager block.

thanks

Emiel

The origin ID is actually a cluster referring to the step name which defines the origin to use (eg. you can detect a straight line in a step called "straight line detection", the step defines two points which define the line. The origin ID will be a cluster containing a string 'straight line detection' and an integer referring to what point to use as origin). I suggest you try out the coordinate functions using the vision assistant and then let the vision assistant build your labview code. This will give you a clearer view on how to use these functions.
