This is one of those things that doesn\u2019t seem that hard until you try to do it. He\u2019s got the mechanical part that can move the camera as fast as the bee flies. But you still have to point the camera correctly. He considered quite a few methods of acquiring and tracking the bee, but he finally settled on a <a href=\"https:\/\/www.youtube.com\/watch?v=SSkJCOriO8E\" target=\"_blank\" rel=\"nofollow noopener\">stereo camera<\/a>. His requirements also made the camera design challenging. In particular, the bees move fast enough that things like USB transmission times become significant. You can see his solution in the video below.<\/p>\n<p>[Jeremy] does a great job explaining all the tradeoffs between frame rate, resolution, focal length, and other optical issues. Of course, he also wanted a global shutter sensor. Rolling shutter cameras scan row-by-row, creating the well-known \u201cjello effect\u201d. Global shutters capture all pixels at once. That also removes any uncertainty as to \u201cwhen\u201d the shutter fired.<\/p>\n<p>All of this is, of course, doubled when you are trying to use two synchronized cameras. Tracking a tiny high-speed flying object isn\u2019t easy. By the end of the video, we don\u2019t get to see bee videos yet, but we feel like he will get there.
