Embodiment 1

[0045] figure 1 It is a schematic flow chart of a method for following an unmanned aerial vehicle according to an embodiment of the present invention, see figure 1 , the following method of the unmanned aerial vehicle comprises the following steps:

[0046] Step S11, installing multiple receiving sensors on the unmanned aerial vehicle, the multiple receiving sensors are matched with one transmitting sensor in the user-side intelligent control device;

[0047] The matching here at least includes: the type of the receiving sensor matches the type of the transmitting sensor. For example, when the receiving sensor is an ultrasonic sensor, the transmitting sensor also adopts an ultrasonic sensor, that is, it is ensured that the transmitting sensor and the receiving sensor are of the same type. And, identity matching between the receiving sensor and the transmitting sensor. For example, during the initialization process, the receiving sensor receives the pairing connection request ...

Embodiment 2

[0055] Ultrasonic signals have advantages in near-field signal transmission, less affected by environmental and lighting factors, stable transmission, strong anti-interference ability, and are an ideal medium for autonomous tracking of unmanned aerial vehicles. Therefore, in this embodiment, taking the receiving sensor as an ultrasonic receiving sensor and the transmitting sensor as an example of an ultrasonic transmitting sensor, the positioning of the user by the unmanned aerial vehicle in the following method of the unmanned aerial vehicle is mainly explained. For other contents, refer to other implementations of the present invention. Example description.

[0056] In this embodiment, at least three ultrasonic sensors are installed on the UAV, and the orientation between the user and the UAV is calculated according to the ultrasonic signals emitted by the ultrasonic transmitting sensor installed in the intelligent control device on the user side.

[0057] The principle of t...

Embodiment 3

[0062] figure 2 It is a schematic diagram of the relative orientation between the unmanned aerial vehicle and the user according to an embodiment of the present invention, image 3 It is a schematic diagram of a spatial Cartesian coordinate system constructed based on the azimuth relationship between an unmanned aerial vehicle and a user in an embodiment of the present invention, combined with figure 2 and image 3 , this embodiment illustrates the process of calculating the orientation of the UAV relative to the user.

[0063] Depend on figure 2 It can be seen that the unmanned aerial vehicle in this embodiment is a quadrotor unmanned aerial vehicle. The quadrotor aircraft changes the rotational speed of the rotor by adjusting the rotational speed of the four motors to achieve changes in flight speed and lift, thereby controlling the attitude and position of the unmanned aerial vehicle. The quadrotor aircraft is equipped with four ultrasonic signal receiving sensors, th...

Abstract

The invention discloses a following method and device of an unmanned aerial vehicle and wearable equipment.The following method of the unmanned aerial vehicle comprises the steps that multiple receiving sensors are installed on the unmanned aerial vehicle and matched with a transmission sensor arranged in intelligent control equipment of a user side; distance signals transmitted by a user in real time are received by the receiving sensors, and the orientation, relative to the user, of the unmanned aerial vehicle is calculated according to the distance signals; the horizontal orientation of the unmanned aerial vehicle is regulated according to the orientation to enable the orientations of the unmanned aerial vehicle and the user to meet the preset orientations, and then automatic following of the unmanned aerial vehicle is achieved.Accordingly, the orientation, relative to the user, of the unmanned aerial vehicle is determined by adopting the mode that multiple receiving sensors are matched with one transmission sensor, the horizontal orientation of the unmanned aerial vehicle is regulated on the basis of the orientation, the relatively still relationship between the unmanned aerial vehicle and the user is kept, and then automatic following on the user is achieved.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to a tracking method, device and wearable device for an unmanned aerial vehicle. Background technique [0002] With the advancement of technology, artificial intelligence has gradually begun to extend to consumer electronics products, and smartphones have almost become a must-have. With the improvement of the quality of life, unmanned aerial vehicles (also known as drones, English UnmannedAerialVehicle) began to enter people's daily life. Tiny multi-rotor unmanned aerial vehicles are now affordable consumer products for most people. [0003] At present, unmanned aerial vehicles are generally equipped with motion state detection sensors such as acceleration sensors and gyroscopes, and Bluetooth and Wi-Fi data transmission technologies are applied to meet the flight control and state detection requirements of unmanned aerial vehicles. However, commonly used data transmissio...
