METHODS AND SYSTEMS FOR OBSTRUCTION DETECTION DURING AUTONOMOUS UNMANNED AERIAL VEHICLE LANDINGS

摘要

Systems and methods for obstruction detection during autonomous unmanned aerial vehicle landings, including unmanned aerial vehicles equipped with at least one video camera, an image processor that analyzes a teed from the video camera to detect possible obstructions, and an autopilot programmed to abort an autonomous landing; if it receives a signal indicating an obstruction was detected. In some examples, the systems and methods are in communication with a ground station to perform obstruction detection analysis instead of performing such processing on board the UAV. In some further examples, the landing area includes a ground-based visual target that the UAV can locate and home in upon from the air.
