vision builder

Hi there !

I'm new in the field of machine vision and I need your help in my project,I want to build an application that inspects the sealed terminals of automative wires like in the image attaches below, calibration and edge detection and comparing the images in the real time to a standard image:womansurprised: ,

I want to know if that is possible ,and if it is how can I do so ?

THANK YOU !

Hi layal,

You are certainly on the right track with using the Vision Builder for Automated Inspection (VBAI). For an extensive outline of all the functions available to you, take a look at the VBAI manual here. First, you would typically want to define a reference coordinate system unless you can guarantee that the part will be located in the same position and orientation in the images. This is discussed on page 2-7 of the manual. Then, you could certainly compare the image, or certain portions in a specified region of interest (ROI) of the image to a template and detect the differences, check for gaps and part widths, locate edges relative to the coordinate system, etc. All the features are outlined in the manual in the context of some examples. I highly suggest that you take a look through the manual and also consider evaluating the VBAI software for 30 days if you do not have it already. You can access the download for the evaluation from the 1st link I posted. If you have more specific questions on the inspection, or how to carry it out, please provide more details concerning the pass/fail conditions for your part.

Also, please bear in mind that if you run VBAI on a regular PC running an OS such as windows, the performance will not truly be real-time. To achieve deterministic performance, you would have to deploy this inspection to a real-time target such as the NI EVS, Smart Camera or a PC running LabVIEW Real-Time as the OS. Hope this helps!

Hi again !

Thank you for your replay , I have the Demo version know and i understand most of the features in the software but i need to know the exact steps to follow if i want to compare the images acquired in real time with the occurred dimensions to my first image to detect the defects like showed in the attachment below , and the most important that i can detect every time measure the crimp height (CH) that must be in an tolerance interval 1.5 to 2.5 mm.

I hope that my problem is clear to you .

Please help me here Joseph-S ,I'm lost 

Think you again !
