Radio-controlled model airplanes: inexpensive tools for low-level aerial photography

摘要

Until now, regulatory and safety constraints have prevented biologists from conducting low-flight aerial reconnaissance in populated areas. We developed a model airplane prototype fitted with a camera, altimeter, and strobe light (which signaled desired height) to take aerial photographs remotely. Our design is limited to fine-scale photographs, but the ability to take such photographs without danger to pilots or passengers may prove beneficial when conventional methods are not possible, practical, or financially feasible.
