detect a crack on boiler headers

[nadiah]

Hi.

Currently my team's members are doing a project entitled development of image acquisition system for robotic inspection of boiler headers.

I, as a part of the team requires to build an application to detect crack on the boiler header by using LabVIEW.

Since this software is new for me, I'm not sure how to start to construct the block diagram.

I've been review the manual for IMAQ but I don't have any idea what functions that I need to use.

Can you give me some guides?

Thank you.

Best regards,

Nadiah.

Before code you must have an idea about the lighting and images you are to analyze.  Have you considered how you will illuminate the cracks and acquire them.

Hello Nadiah,

I recommend starting out by familiarizing yourself with some of the examples available in LabVIEW for machine vision.  Launch LabVIEW and select Help»Find Examples.  Then, browse to the folder entitled Hardware Input and Output»IMAQ or IMAQdx (depending on which driver set you will be using).  There are also examples available by browsing to Toolkits and Modules»Vision.  Try opening up a few different examples to familiarize yourself with vision in LabVIEW.  You can even use an example that is close to what you are trying to implement as a foundation for your code and build from there.

As Paul already pointed out, there are many considerations to take into account before beginning to write code.  I would recommend familiarizing yourself with vision implementation strategies, determining the environmental factors you will have to take into account, deciding what hardware you will be using, and then develop an algorithm based on everything.  Once you are happy with your algorithm and process, implement it as code.

Thanks Mr Paul for your replied.

For my project I decides to load the image one by one. We are not using the video camera to analyse the picture. Can you suggest me several methods to illuminate the cracks?

Hello Mr Patrick. Thanks for your replied.

I've seen some of the examples that I think would help me. Can you explain more about the environmental factors to take into account that you said?
