Re: Field lighting interference with camera tracking
My understanding of retro-reflectivity (the material of the target rectangles) is that you only see them light up when the light source and the camera/eye are coaxial. This was our observation using infrared lighting on the robot, and observing sunlight coming in at a particular angle in the shop. We used Infrared because we thought there was not likely to be another infrared source behind the baskets. We tried several colors of LED lights around the robot, but ended up sticking with the IR.
This may be too late to help you this season; my apologies.
But - can you narrow your cameras field of vision, so it only picks up light being reflected back to your camera directly?
