camera selection for screw thread analysis

yes of course, but for the time being I need to start with the experiment, so I need a trusted hardware.

so this is going to be only proto type, so if things are OK, and need further cost reduction, definitely  we will be looking other ones.

 

Other than cost, do you feel anything wrong can happen.

 

Between I would like to know, little bit more about teh image acquisition,

 

I need to compare a good image aganist a defective screw image. Do you think, if I move the screw in the FOV camera, in a pre defined speed, do we get a single image, the camera is progressive scan.

I guess you will also need to trigger (either a soft/hardware) to get the positional accuracy going. I have used guppy and found that to be a good relaible one.. go for it if cost is not the criteria...

that's great, You have experience with AVT guppy, so definitely you can help me out during the set up.

 

Have used any software like Vision Pro, or Vision Build for the image analysis, or used the SDK of the camera itself.

The low cost, 4 and 5 MP, CMOS cameras have rolling shutters.  This is true of the Guppy F-503B.  The manufacturer recommends that you use a strobe light in combination with the camera's "Global Reset Release Shutter" if imaging moving objects with the camera, see page 169 of the manual located at http://www.alliedvisiontec.com/fileadmin/content/PDF/Products/Technical_Manual/Guppy/Guppy_TechMan_V....

 

I have used the Guppy F-503B with the NI Vision Builder for Automated Inspection and Vision Development Module without issues.

Any idea about Epix camera, I kept F503 guppy in my file for some time, because they said, it will take another one month for the delivery.

 

Do you have any idea about Epix Cameras,

No idea, Just placed a request to the epix team for the details, Will see.

 

Have you used any of the Imaging source cameras.

 

I gone through  the following

 

http://www.theimagingsource.com/en_US/products/cameras/usb-cmos-mono/dmk41buc02/

 

They don't have good  vertical resolution.  I made this statement from the following. My vertical FOV is 30 mm,

 

For a 1944 Vertical resolution sensor, 30mm/1944 = 0.015432mm/pixel.  The smallest measurement I can accurately make is 0.02929mm*2=0.0308mm.

If it is 1024, again I don't think I can measure the smallest bit accurately.

 

Please tell me your suggestion.
