Hi I have a problem on edge detection. I have a pulley of different types.Pulleys where Dia is same, but height differs. Pulleys of different dia but the number of teeth (ridges) vary.I need to identify one type of pulley from the other. I am trying to use the following logic:1. Locate the base of the pulley (which is distinct) using pattern match2. Define a co ordinate based on this pattern match.3. Define edge detection tool using the co ordinate (this is where I am running into a wall)I have used extracts of examples : battery inspection, gage and fuse inspectionI am not able to define the edge tool (Edge detector under vision assistant 7.1)I am trying to use the co ordinates, since if the pulley moves a bit, then the edge detector appears away (in Vision assistant)THE CATCH IS:I have to do this in VB since Machine vision has to be integrated into existing vb application.NOTE: attached image of pulleyNow can some one help me PLSThanks in advanceSuresh
