Using Digital images to count fish in water past a particular point

Using Digital images to count fish in water past a particular point

Using Digital images to count fish in water past a particular point

(OP)
Can anybody tell me how I could use a digital video camera to count fish going through a channel (say 300mm wide)  Note the fish are of various sizes and may swim in groups.

I look forward to replies

RE: Using Digital images to count fish in water past a particular point

Allen Bradley has visual detection and monitoring equipment that might help.  It can work through their PLC system. They use it for part recognition, sorting, and quality control.

RE: Using Digital images to count fish in water past a particular point

Whoa...that would be a neat VISION APPLICATION! But sounds like it would be very tough. Lighting would be very important. I would recommend a high end vision system like Acuity http://www.rvsi.com/acuitycimatrix/index.htm or DVT http://www.dvtsensors.com/products/

If you can take a digital picture of the fish, you can download DVT's Framework from their website and see if you can detect various fish with different JPG images you take and load them into the FrameWork software with little or no money you could detrimine if this type of vision system will work for your vision "Fish" project....sounds kewl!
