So, we (mainly @albags ) have done some tests to compare the camera we currently use in the AMI-trap with the range of cameras that are available for the Pi. I said in a thread somewhere that I would share our results, I can't find that thread, so here are the results.
First, the cameras we tested were:
And the Hawkeye could not run at the full potential of 64MP because the Raspberry Pi we were using was not powerful enough, so it is at 32MP in the below.
Here is the standard image that we took with each of the camera, though in the results I'm just going to show you a small part of each image so you can really get an idea of the variation in quality. The board had a 'test card' print out on it with a few moth wings attached for good measure.
In the comparison you can see that all the Pi cameras are better than the webcam and are also much smaller and cheaper. There is not a big difference between the two mid-range cameras but the hawkeye is better quality, even running at half the resolution it can do. The Hawkeye is picking up individual scales on the butterfly's wing. That might be overkill for many applications, and generates bit image files, but if you need that kind of resolution its pretty good!
