novice ni vision assistant

hello, im a student and have to accomplish a task using labview 7.0 and vision assistant 7.1 and i d be glad if you could help me,
there are pictures of pcb boards and i want simple detect an ic on it . so far pattern matching to find the ic and so on is ok, but i would like to measure the distance of the ic from the side of the board, but the images are rotated ,so i would need to set a coord.sys on the edge of the board that can be found on the rotated image as well.. im not so into it right now, ive read the simple calibration.vi, and so but i dont get it how to implement this thing into v.assist..

hi, basically thats my problem i do this easy pattern matching but i also want to measure the distance of the ic from the side of the board, and count the pins of the ic, id like to inspect more images which are rotated ,but then i lose track of the edge detection line ,and the distance is not measured from the side...

ive attached the script, the vi and an example image . i looked at the labview ref.coord.sys i think it would help me getting it somehow into my script..

thanks for the help

Dear Benarivo,

there is no possibility to do the inspection with rotated images in the Vision Assistant.
Please take a look at the shipping examples from LabVIEW/Vision.
The Simple Calibration example show how you could calibrate a rotated image.
The Circle Distance Example example how to measure the distances between objects.

Best regards

Benjamin
