118. The control terminal of claim 113, wherein the colour and/or size of the obstacle icon is determined from the distance between the perceived obstacle and the drone.

119. The control terminal of claim 113, wherein when the distance between the sensed obstacle and the unmanned aerial vehicle is less than or equal to a preset warning distance, the obstacle icon flashes at intervals of a preset duration, and/or a warning tone is broadcasted to remind a user to avoid the obstacle.

120. The control terminal of claim 94, wherein the flight director compass includes an obstacle sensing blind area and an obstacle sensing area, the colors of the obstacle sensing blind area and the obstacle sensing area being different.

121. The control terminal of claim 120, wherein the number of obstacle sensing blind zones is determined from the number of rotors of the drone.

122. The control terminal of claim 94, wherein the processor is further configured to implement the steps of:

123. The control terminal of claim 122, wherein when an obstacle is sensed above and/or below the drone, the right display area of the flight directing compass further displays an obstacle indicator bar for indicating a distance between the drone and the obstacle.

124. The control terminal of claim 122, wherein a flying distance indicating line is further displayed on a right display area of the flying direction compass, the flying distance indicating line is used for indicating a flying distance of the drone in a vertical direction, and a length of the flying distance indicating line is determined according to a vertical speed of the drone and a preset time.

125. The flight guidance device is applied to a control terminal, the control terminal is communicated with a unmanned aerial vehicle, and the flight guidance device comprises a processor and a memory;

the memory is used for storing a computer program;

controlling the control terminal to display a flight guidance page;

126. A flight guidance system comprising a drone and a control terminal according to any one of claims 63 to 124, the control terminal being in communicative connection with the drone.

127. A computer-readable storage medium, characterized in that the computer-readable storage medium stores a computer program which, when executed by a processor, causes the processor to implement a flight guidance method according to any one of claims 1 to 62.
