Abstract

The invention belongs to the technical field of unmanned aerial vehicles and provides an unmanned aerial vehicle auxiliary landing method, device and equipment and a storage medium. The method comprises the steps that the current liftoff distance is measured through an infrared sensor; the current temperature value is obtained through a temperature sensor, according to the temperature value, the safe liftoff distance is determined; and when an unmanned aerial vehicle is located in the safe liftoff distance, image information is obtained and subjected to mist elimination treatment to obtain restored image information. The liftoff distance is measured through the infrared sensor, the safe liftoff distance is determined through the temperature sensor, so that the unmanned aerial vehicle is located in the safe liftoff distance in the landing process, and the image information can be obtained by a ground station through an unmanned aerial vehicle camera to observe the liftoff condition of the unmanned aerial vehicle; and in order to obtain the clear image information, the image information is subjected to real-time quick mist elimination treatment so that a clear image can be obtained to distinguish position information, and therefore reconnaissance monitoring and accurate landing of the unmanned aerial vehicle under a field environment can be achieved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to an auxiliary landing method, device, equipment and storage medium of an unmanned aerial vehicle. Background technique [0002] UAVs are mainly used in the military field. They have the characteristics of zero damage, low cost, and good concealment. They are used for investigation and monitoring, military strikes, fire guidance, and communication relay. In recent years, the flexibility, efficiency, and reliability of UAVs in the process of performing tasks have attracted widespread attention from the civilian market, and are widely used in fields such as electricity, agriculture, meteorology, and geology. The terrain of wild mountains and forests is complex, the area is vast, and the climate is unpredictable. Forest fire prevention is particularly important. Using the aerial image information of drones, the location of the fire point and the fire situa...
