This invention provides a method and system for long-range lip-reading recognition using unmanned aerial vehicles (UAVs), belonging to the fields of artificial intelligence and UAV technology. The system utilizes a camera, IMU (Integrated Mutor Unit), and microphone mounted on the UAV to acquire video streams, IMU data streams, and audio streams. Motion compensation is applied to the video stream using IMU data to stabilize image frames. Then, image sequences of the target speaker's lips and nasal / jaw region are extracted and input into a lip-reading recognition model to obtain initial recognition text and visual confidence scores. Simultaneously, the signal-to-noise ratio (SNR) of the audio stream is calculated. When the visual confidence score is low and the SNR is high, the audio recognition process is triggered, generating audio recognition text and an audio confidence score. Finally, the visual and audio confidence scores, along with the lip movement-audio temporal matching degree, are weighted and fused to generate the final recognition text. This invention effectively solves the problems of video instability and background interference in long-range lip-reading recognition, improving recognition accuracy in complex environments.
