Unmanned aerial vehicles have shown great potential in fast shipping and delivery, including delivering emergency support and services to the disaster (natural or manmade) hit areas where manual reach is infeasible. For accurate and effective emergency service delivery at the adverse sites, the UAVs need to fly close to the ground. Due to the low-altitude flight, there may be many stationary obstacles (e.g., trees and buildings) on the path of a UAV. Detecting these obstacles is crucial for successful mission accomplishment and evading crash. The existing obstacle detection methods limit the flying speed of a UAV due to the latency in processing and analysing the in-flight sensed data. To mitigate this, we propose to equip the UAV with the prior information of the obstacles on its trajectory. In case of an obstacle, the UAV slows down to avoid the obstacle; otherwise, it travels with a much higher speed. As experiment, we fed the UAVs with the satellite images from the Google Maps. It is observed that the proposed approach improves the overall flying speed of the UAVs to a great extent.
