- Lasers are dangerous when used out in the open.
- Gimbal is not accurate enough.
- Camera will probably never pick up wasps/hornets in flight.
- Variable outside lighting conditions will always be a problem.
The proposed solution is to police the entrance to the hive by forcing the creatures to travel up the length of a 25 mm aluminum box section which has a camera mounted in the middle, looking inwards. I checked the Logitech C230e focus and it is effective to 22mm from the front of the camera, so 25 mm box is perfect. There's also a 1000 mA laser head available with 25 x 25 mm front profile. The insects will crawl over the top of the laser and get spotted by the camera as they go. If a wasp or hornet is spotted ..... they get blasted by the laser. The bees *should* clear out the dead bodies themselves if they are not completely vapourised for some reason.
Small LEDs can be mounted at strategic locations within the box tunnel to help the camera.Currently they are green, as those were the only ones i had lying around.
Here's a camera side view:
This is with only a couple of LEDs. Once the lighting is sorted, the image will be very nice - perfect for feeding into the object detection system.
