BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 A schematic flow chart of the steps of a method for remotely controlling the flight attitude of an unmanned aerial vehicle (UAV) provided by one embodiment of the present invention.

[0017] Figure 2 A schematic diagram of the basic flow of a remote control system for the flight attitude of an unmanned aerial vehicle provided by one embodiment of the present invention. DETAILED DESCRIPTION

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings. It is obvious that the described embodiments are only part of the embodiments of the present invention, but not all of the embodiments.

[0019] Example 1, with reference to Figure 1 , as one embodiment of the present invention, provides a method for remotely controlling the flight attitude of a UAV, comprising: Step S1: Wear the myoelectric armband on the operator's forearm to collect the operator's electromyographic signals when performing different preset gestures.

[0020] Step S2: Process the electromyographic signal to obtain a feature vector, and combine multiple feature vectors representing different gestures to obtain a feature vector template.

[0021] Step S3: Calculate the current feature vector, compare the current feature vector with the feature vector template, and recognize the current gesture.

[0022] Step S4: Establish a mapping rule table, map the current gesture to a drone control instruction, and determine the drone control signal according to the drone control instruction.

[0023] Step S5: Before sending the drone control signal to the drone, the control command is double-verified. When an abnormal situation occurs, different emergency gestures are used according to different abnormal situations.

[0024] Step S1 specifically includes: The myoelectric armband is worn on the operator's forearm and includes multiple myoelectric sensors.

[0025] The myoelectric signals of the operator when performing different preset gestures on the myoelectric sensor are collected. The different preset gestures include fist clenching, stretching, finger flexion, relaxation, wrist raising, wrist pressing and emergency gestures.

[0026] The collection method and content of electromyographic signals were clarified, laying the foundation for subsequent gesture recognition and drone control.

[0027] Step S2 specifically includes: The electromyographic signal is processed to obtain a feature vector, and multiple feature vectors representing different gestures are combined to obtain a feature vector template. The processing includes signal cleaning and extraction.

[0028] The signal cleaning process includes using a bandpass filter to remove noise and interference from the electromyographic signal to obtain a first electromyographic signal, and rectifying and smoothing the first electromyographic signal to obtain a second electromyographic signal.

[0029] Converting electromyographic signals into stable and recognizable second electromyographic signals lays the foundation for feature extraction.

[0030] The extraction process includes extracting multiple features from the second electromyographic signal that can distinguish different preset gestures, using a filtering method to screen out useful features of the multiple features, and combining the useful features to form a feature vector. The multiple features include time domain features, frequency domain features, and time-frequency features.

[0031] Each preset gesture is repeatedly executed and the electromyographic signal of each repeated preset gesture is collected. The electromyographic signal of each repeated preset gesture is subjected to signal cleaning and extraction processing to obtain multiple feature vectors representing different gestures. The multiple feature vectors representing different gestures constitute a feature vector template.

[0032] Repeating each preset gesture and collecting the electromyographic signals of each repeated preset gesture can obtain richer data, reduce recognition errors caused by individual differences and environmental noise factors, and improve the robustness and generalization ability of the feature vector template. Signal cleaning and extraction processing of the electromyographic signals of each repeated preset gesture can ensure that the feature vectors in the feature vector template can accurately reflect the characteristics of different gestures, thereby improving the accuracy of gesture recognition.

[0033] Step S3 specifically includes: Collect the current electromyographic signal, perform signal cleaning and extraction processing on the current electromyographic signal, determine the current feature vector, compare the current feature vector with the feature vector template, and recognize the current gesture.

[0034] The current feature vector is compared with the feature vector template to find the best matching feature vector, thereby identifying the operator's current gesture and realizing real-time interpretation of the drone control instructions, ensuring that the system can respond to the operator's gesture instructions quickly and accurately, and improving the flexibility and reliability of drone control.

[0035] The comparison specifically includes: A similarity measurement method is used to calculate the similarity between the current feature vector and the feature vector template. If the similarity is greater than or equal to a first threshold, the gesture corresponding to the feature vector template is the current gesture.

[0036] Step S4 specifically includes: A mapping rule table is established based on different preset gestures. The mapping rule table includes fist clenching corresponding to the drone take-off command, stretching corresponding to the drone landing command, bending the fingers corresponding to the drone left flight command, relaxing corresponding to the drone right flight command, raising the wrist corresponding to the drone acceleration command, pressing the wrist corresponding to the drone deceleration command, and emergency gestures corresponding to the drone preset safety command. The current gesture is mapped to the drone control command, and the drone control signal is determined according to the drone control command.

[0037] A mapping rule table is established according to different preset gestures, which establishes a clear connection between gestures and drone control instructions, laying the foundation for subsequent gesture control. The current gesture is mapped to the drone control instruction, realizing the conversion from gesture recognition results to specific drone control instructions. It is a key link in the process of gesture control of drones. The operator can achieve precise control of the drone through simple gestures, which improves the convenience and flexibility of drone operation, and enables the drone to quickly respond to the operator's intentions and perform various complex flight missions.

[0038] Step S5 specifically includes: Before sending the drone control signal to the drone, the control command is double-verified. The double verification includes the initial verification of the control command and the secondary confirmation of the control command. When an abnormal situation occurs, different emergency gestures are used according to different abnormal situations. When the operator performs the emergency gesture, the drone immediately executes the preset safety instructions. Different abnormal situations include the drone needing to make an emergency landing, the drone needing to hover urgently, the drone's GPS signal lost, and the drone's low battery warning.

[0039] Double verification of control commands significantly improves the reliability and safety of drone operations through a multi-level security mechanism. It not only effectively avoids the risks brought by misoperation and abnormal situations, but also enables rapid response in emergency situations, thereby providing drones with more stable and safe flight guarantees.

[0040] The initial verification and secondary confirmation of control instructions specifically include: Initial verification of control commands: Verify whether the control commands correspond to the gestures in the mapping rule table and whether the control commands match the current state of the drone. The state includes flight mode, flight altitude, and drone battery level. If the control commands pass the initial verification, a second confirmation of the control commands will be performed.

[0041] Confirm whether the control command corresponds to the gesture in the preset mapping rule table to prevent the input of invalid or erroneous commands, and verify whether the control command matches the current flight status of the drone, including flight mode, flight altitude and drone power. Only when the control command successfully passes the initial verification will it enter the next step of the control command secondary confirmation link.

[0042] Second confirmation of control instructions: For key control instructions, the operator performs the preset gesture again after performing the preset gesture.

[0043] After the operator issues a preset gesture, he must repeat the same preset gesture again for secondary confirmation, which further improves the safety and reliability of drone control.

[0044] Different emergency gestures are used according to different abnormal situations, including: Drone needs to make an emergency landing: Clench your fist twice in rapid succession.

[0045] Drones need to perform emergency landings when they encounter collision risks, suffer serious system failures, enter no-fly zones, encounter drastic weather changes, or receive emergency landing instructions. This can maximize the safety of the drone and its surroundings and avoid accidents.

[0046] The drone needs to hover urgently: quickly cross your arms over your chest.

[0047] The drone needs to perform emergency hovering in the early stages when it encounters a temporary obstacle, encounters signal interference, the operator needs to make temporary adjustments, and there is a low battery warning. This can help the drone to briefly stop and reassess the flight status and surrounding environment while ensuring safety, and then continue flying when conditions permit.

[0048] Drone GPS signal lost: Open your five fingers and quickly make a fist.

[0049] Trigger the drone to execute pre-set safety procedures to ensure that the drone can respond safely even if it loses its positioning.

[0050] Drone low battery warning: Lay your hand flat and quickly press your wrist down.

[0051] Guide the drone to perform preset safety operations based on the remaining power, avoiding drone crashes due to power exhaustion and ensuring flight safety.

[0052] Through these clear emergency gestures, operators can respond quickly in emergency situations, guide the drone into a safe state, effectively avoid potential dangers, and improve the safety and reliability of drone flight.

[0053] Example 2, reference Figure 2 The present invention provides a remote control system for the flight attitude of an unmanned aerial vehicle, which includes a signal acquisition module, a signal processing module, a gesture recognition module, a control instruction conversion module and a safety assurance module.

[0054] The acquisition module is used to wear the myoelectric armband on the operator's forearm and collect the operator's electromyographic signals when making different preset gestures.

[0055] The signal processing module is used to process the electromyographic signal to obtain a feature vector, and combine multiple feature vectors representing different gestures to obtain a feature vector template.

[0056] The gesture recognition module is used to calculate the current feature vector, compare the current feature vector with the feature vector template, and recognize the current gesture.

[0057] The control instruction conversion module is used to establish a mapping rule table, map the current gesture into a drone control instruction, and determine the drone control signal according to the drone control instruction.

[0058] The safety assurance module is used to double-verify the control instructions before sending the drone control signal to the drone. When an abnormal situation occurs, different emergency gestures are used according to different abnormal situations.

[0059] The present invention collects the operator's gesture and electromyographic signals through a myoelectric armband, and directly maps natural gesture movements into drone control commands, achieving an intuitive and natural control method and lowering the operating threshold.
