If the distance between the perceived obstacle and the drone is greater than the preset warning distance, and the preset warning distance is less than the preset distance, the obstacle icon is a green box, if the perceived obstacle is from the drone If the distance between the obstacles is less than or equal to the preset warning distance, the obstacle icon is a yellow box, and the yellow box flashes at the preset time interval, and the first warning tone is played at the same time. The distance between the human and the machine is less than or equal to the preset stopping distance, the obstacle icon is a red box, and the red box flashes at the preset interval, and the second warning tone is broadcast at the same time.

In some embodiments, the flight guidance compass includes an obstacle perception blind zone and an obstacle perception zone. The obstacle perception blind zone and the obstacle perception zone have different colors. The number of the obstacle perception blind zone depends on the rotor of the drone. The number is determined. Among them, the obstacle perception blind zone is the space area where the UAV cannot perceive the obstacle. The obstacle perception blind zone on the flight guidance compass is symmetrically distributed. The obstacle perception blind zone is fan-shaped with a preset angle, and the obstacle perception area is larger than the obstacle. Perceive the area of the blind zone. By displaying the obstacle perception blind area and obstacle perception area on the flight guidance compass, the user is aware of the obstacle perception blind area and improves the flight safety of the UAV.

Exemplarily, as shown in FIG. 5, the flight guidance compass includes 4 obstacle perception blind areas and 4 obstacle perception areas. The color of the obstacle perception blind area is gray, and the color of the obstacle perception area is white. When you start reading in a clockwise direction, you can see that the angle range of the first obstacle perception blind zone is between 330° from the true north direction and 360° from the true north direction, and the angle range of the second obstacle perception blind zone is the deviation from true north. Between the direction of 60° and the deviation of 90° from the true north direction, the angle range of the third obstacle sensing blind zone is between 150° from the true north direction and 180° deviation from the true north direction, and the angle range of the fourth obstacle sensing blind zone is deviation Between 240° from true north and 270° from true north, the flight guidance compass displays two obstacle icons. Reading clockwise from the nose direction, you can see that the first obstacle icon is located at 60° from true north. The first obstacle icon is an arc-shaped line segment, the second obstacle icon is located in a position area 180° from the true north direction, and the second obstacle icon is a quadrilateral.

In some embodiments, it is determined whether the obstacle sensed by the drone is located above and/or below the drone; if it is determined that the obstacle sensed by the drone is located above and/or below the drone, it is determined according to Obstacle information displays an obstacle indicator bar on the flight guidance page. The obstacle indicator bar is used to indicate the distance between the drone and the obstacle. The length of the obstacle indicator bar varies with the distance between the drone and the obstacle. If it is determined that the obstacle perceived by the drone is located in the front, rear, left, and/or right of the drone, the obstacle information will be displayed on the flight guidance compass. Wherein, the display position of the obstacle indicator bar on the flight guidance page can be set according to actual conditions, which is not specifically limited in this application. For example, the obstacle indicator bar is displayed in the right display area of the flight guidance compass. By displaying the obstacle indicator bar when the obstacle sensed by the drone is above and/or below the drone, the user can know the difference between the obstacles above and/or below the drone and the drone. It is convenient for the user to control the drone to avoid obstacles in time and ensure the flight safety of the drone.

In some embodiments, only when an obstacle is sensed above the drone, the obstacle indicator is displayed at the upper end of the obstacle indicator bar, and the distance between the drone and the obstacle is also displayed near the upper end; Only when an obstacle is detected below the drone, the obstacle indicator is displayed at the lower end of the obstacle indicator bar, and the distance between the drone and the obstacle is also displayed near the lower end; above the drone When an obstacle is sensed at and below, the upper and lower ends of the obstacle indicator bar display obstacle signs, and the distance between the drone and the obstacle above is displayed near the upper end, and the distance between the drone and the obstacle is displayed near the lower end. The value of the distance between the obstacles below. Among them, the shape of the obstacle mark can be a circle, rectangle, triangle or other shapes. When the obstacle is sensed above the drone, and the drone is constantly approaching the obstacle, the obstacle mark is continuously pressed down. The displayed obstacle indicator bar is gradually shortened. When the unidentified person keeps moving away from the obstacle, the obstacle mark continues to rise, making the displayed obstacle indicator bar continuously stretch.

In some embodiments, when the distance between the drone and the obstacle is greater than or equal to the first preset distance, the obstacle indicator bar includes a first line segment, a second line segment, and a third line segment, and the first line segment The colors of the first line segment, the second line segment and the third line segment are different. The length of the first line segment, the second line segment and the third line segment changes with the distance between the drone and the obstacle. Among them, the colors of the first line segment, the second line segment, and the third line segment can be set based on actual conditions, which are not specifically limited in this application. For example, the color of the first line segment is red, and the color of the second line segment is yellow. , The color of the third line segment is green. By displaying three line segments in different colors, it is convenient for the user to know whether the distance between the drone and the obstacle is a safe distance, and it is convenient for the user to control the drone to fly.

It is understandable that red means that the distance between the drone and the obstacle is very close, and the possibility of collision between the drone and the obstacle is high, and yellow means that the distance between the drone and the obstacle is relatively short, and no one is there. The probability of collision between the drone and the obstacle is higher. The green color indicates that the distance between the drone and the obstacle is far, and the probability of collision between the drone and the obstacle is less.

In some embodiments, when the distance between the drone and the obstacle is less than the first preset distance and greater than or equal to the second preset distance, the obstacle indicator bar includes a first line segment and a second line segment, and The first preset warning sound is broadcast, and the first preset warning sound is used to remind the user that the drone is within the obstacle avoidance warning range.

In some implementations, when the distance between the drone and the obstacle is less than the second preset distance and greater than or equal to the third preset distance, the obstacle indicator bar includes the first line segment and broadcasts the second prediction. An alarm sound is set, and the second preset alarm sound is used to remind the user that the drone is within the obstacle avoidance braking range. When the drone is gradually approaching an obstacle and the distance between the drone and the obstacle is dangerous, only the first red line segment will broadcast the alarm sound to remind the user that the drone is within the obstacle avoidance parking range. There is a greater risk of collision with obstacles, which is convenient for users to control drones to fly to avoid obstacles in time.

In some embodiments, when the distance between the drone and the obstacle reaches a fourth preset distance, the drone is controlled to stop, wherein the first preset distance is greater than the second preset distance, and the second preset The distance is greater than the third preset distance, the third preset distance is greater than the fourth preset distance, and the first preset distance, the second preset distance, the third preset distance, and the fourth preset distance can be set by the user. This application does not specifically limit this, for example, the first preset distance is 16 meters, the second preset distance is 12 meters, the third preset distance is 8 meters, and the fourth preset distance is 5 meters. When the drone is gradually approaching obstacles and the distance between the drone and the obstacle is very close, when the drone is about to collide with the obstacle, the drone will be automatically controlled to stop to avoid the drone colliding with the obstacle. Ensure the flight safety of drones.

Among them, the first preset distance, the second preset distance, the third preset distance, and the fourth preset distance can be set by the user, which is not specifically limited in this application. For example, the first preset distance is 16 meters. , The second preset distance is 12 meters, the third preset distance is 8 meters, and the fourth preset distance is 5 meters. When the distance is 18 meters, the displayed obstacle indicator bar includes a red line segment, a yellow line segment and a green line segment. When the drone is constantly approaching the obstacle, the green line segment of the obstacle indicator bar keeps getting shorter. When the distance between man and machine is less than or equal to 12 meters, the green line segment of the obstacle indicator bar disappears, and only the red line segment and yellow line segment are displayed. If the drone continues to approach the obstacle, the yellow line segment of the obstacle indicator bar will gradually shorten. When the distance between the obstacle and the drone is less than or equal to 8 meters, the yellow line segment of the obstacle indicator bar disappears and only the red line segment is displayed. If the drone continues to approach the obstacle, the red line segment of the obstacle indicator bar gradually Shorten it and control the drone to stop when the distance between the obstacle and the drone is less than or equal to 5 meters.
