Title: UNMANNED AERIAL VEHICLE AND FLIGHT LEVEL CONTROL METHOD UTILIZED IN UNMANNED AERIAL VEHICLE
Abstract:
An unmanned aerial vehicle and a flight level control method utilized in an unmanned aerial vehicle. The unmanned aerial vehicle comprises an infrared emitter module (10) and an infrared receiver module (11). The method comprises: acquiring an infrared emission time and an infrared receiving time, computing, according to a time difference between the infrared emission time and the infrared receiving time, distance information between the unmanned aerial vehicle and an obstacle thereunder; and when the distance information does not satisfy a preconfigured height, adjusting a flight level of the unmanned aerial vehicle to fly at a distance satisfying the preconfigured level difference. Since the infrared emitter module (10) and the infrared receiver module (11) can be made into compact forms, they can produce an infrared spot having a small size and not easily absorbed by an object, being high in precision, fast in response, applicable in a low light region, and low in cost.
