Ideas on presenting a DEMO using IMAQ

I am new to LabVIEW and I need some advice and help towards finishing my project.

I have attached a picture that presents two solar cells, one that is damaged and the other one which is in good working condition.

I have an automated system that inspects the solar cells while they have a reverse bias being applied.

 

I would like to extract useful information from the pictures (or actual video). I have also attached the current VI I have been using, you can give yourself a good idea of what I have done so far.

 

I have tried using a histogram, but the idea of having a delta function spiking up is not so apeseaing, therefore, I am trying to find out different ways to present the pixel intensity or a read out of the solar cells.

Any ideas would be greatly appreciated.

Thank you

Hi Selp,

 

You could use a Threshold on your image so the user could see a visualization of what parts of the solar panel are damaged. There is a good shipping example of this in LabVIEW. If you go to Help>Find Examples...>Toolkits and Modules>Vision>Applications>Threshold Example.vi. Then from that threshold and histogram you could give the user an accurate estimated percent of damaged or show exactly which cells are damaged.
