[0003] The UAV needs to be controlled. The current UAV control method is mainly based on the joystick and control software to control the UAV, but the existing UAV control method has many inconveniences. By controlling the joystick, It can quickly adjust the UAV, but it cannot fully adjust the UAV for those who need precise control; and control the UAV through software, which can provide precise control of various parameters of the UAV, but it needs to be compared When there are multiple control options, it may need to be carried out in the second or even third-level menu in the control software, which brings a lot of inconvenience

Embodiment 1
[0043] Embodiment 1 of the present invention discloses a method for controlling a drone based on voice, which is applied to a voice system and a drone control system; wherein, such as figure 1 As shown, the method includes the following steps:
[0044]Step 101. Obtain the voice control commands associated with the drone to be controlled issued by the operator through the voice system, and perform voice recognition and semantic understanding on the voice control commands to obtain the command intent;
[0045] Specifically, such as figure 2 As shown, the voice system includes a pickup microphone and a business system; wherein the business system includes an offline ASR (Automatic Speech Recognition, automatic speech recognition) module, an offline NLU (Natural Language Understanding, natural language understanding) module;
[0046] Thus, in step 101, the voice control command associated with the unmanned aerial vehicle to be controlled issued by the operator is obtained throug...
Embodiment 2
[0076] In order to further illustrate this solution, Embodiment 2 of the present invention also discloses a device for controlling drones based on voice, which is applied to voice systems and drone control systems; wherein, as image 3 As shown, the equipment includes:
[0077] The obtaining module 201 is used to obtain the voice control instructions associated with the unmanned aerial vehicle to be controlled issued by the operator through the voice system, and perform voice recognition and semantic understanding on the voice control instructions respectively to obtain the instruction intention;
[0078] A determining module 202, configured to perform business decision analysis based on the instruction intention, preset business execution rules, and current status information of the UAV to determine the execution result of the instruction intention;
[0079] The control module 203 is used to send the intention control instruction to the UAV control system through the voice sy...

Abstract
The invention provides a method and device for controlling an unmanned aerial vehicle based on voice. The method and the device are applied to a voice system and an unmanned aerial vehicle control system. The method comprises the steps of: obtaining a voice control instruction which is sent by an operator and associated with a to-be-controlled unmanned aerial vehicle through a voice system, and performing voice recognition and semantic understanding on the voice control instruction so as to obtain an instruction intention; performing service decision analysis based on the instruction intention, the preset service execution rule and the current state information of the to-be-controlled unmanned aerial vehicle to determine the execution result of the instruction intention; and if the execution result meets a preset execution rule, sending the intention control instruction to the unmanned aerial vehicle control system through a voice system so as to control the to-be-controlled unmanned aerial vehicle through the unmanned aerial vehicle control system. According to the scheme, the defects in the prior art are overcome, the intelligent voice technology is used for assisting in controlling the unmanned aerial vehicle, the intelligence of voice control is met, the accuracy of a manual operation system is also met, and control is easy and convenient.
Description
technical field [0001] The invention relates to the field of drone control, in particular to a voice-based method and device for controlling drones. Background technique [0002] Unmanned aircraft, referred to as "drone" for short, and "UAV" for English abbreviation, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. Without a pilot on board, drones tend to be better suited for missions that are too "dumb, dirty or dangerous" than manned aircraft. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industry applications are the real rigid needs of drones; currently, they are used in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news re...
