A very cool new toy arrived at our door a couple of days ago. It is a camera copy stand that will hold a cellphone or other arbitrary item that fits a certain form factor. It will be invaluable in the bean sorting project, but I will be able to use it for a lot of other machine vision image capture testing tasks. We have made a lot of progress on the project and expect to start buying the actual cameras and lighting we hope to use within the next few weeks. The next difficult task is to drop the beans past a camera while we synchronize the capture and lighting of the scene so the bean is not blurry and we can see the surface of both sides very well. There are more tricky little things we need to do after that, but we cannot move forward until we know that is possible. As soon as that is figured out, I will see if Gene can help me set up a more permanent test fixture to systematically drop beans past the cameras so we can gather a test set from which to build a classifier.
