Abstract: A UAV is provided to cancel background noise from audio data collected by the UAV. The UAV is provided with one or more background microphones in a proximity of one or more background noise-producing components. The UAV is also provided with one or more audio source collecting microphones. The audio data collected by the background microphones may be used to reduce or cancel interfering background noise from the audio signal detected by the audio source collecting microphone. The target audio may be captured or recorded with little or no background noise.
Abstract translation: 提供无人机以从UAV收集的音频数据中消除背景噪声。 无人机在一个或多个背景噪声产生部件附近提供一个或多个背景麦克风。 无人机还提供一个或多个音频源收集麦克风。 由背景麦克风收集的音频数据可以用于从由音频源收集麦克风检测的音频信号中减少或消除干扰背景噪声。 可以很少或没有背景噪声来捕获或记录目标音频。

Abstract: Provided is a method of correcting a defective pixel of a digital image. In the method, the defective pixels are pre-corrected. The similarities of normal pixels and each defective pixel are calculated. The weight of each normal pixel to each defective pixel is calculated based on the similarities of the normal pixels and each defective pixel. The weight of each normal pixel to each defective pixel is normalized. The normalized weighted values of the normal pixels to each defective pixel are weighted summed to obtain the corrected pixel value of each defective pixel.

Abstract: An unmanned aerial vehicle (UAV) with audio filtering components includes a background noise-producing component, a background microphone, and a noise emitter. The background noise-producing component is configured to produce a background noise. The background microphone is positioned within a proximity sufficiently close to collect interfering noise from the background noise producing component. The background microphone is configured to collect audio data including the background noise. The noise emitter is disposed within a proximity sufficiently close to the background noise-producing component to reduce the interfering noise. The noise emitter is configured to emit an audio signal having a reverse phase of the audio data collected by the background microphone.

Abstract: A method and an apparatus for adjusting installation flatness of a lens in real time are provided. The method comprises: acquiring an image captured by a camera in real time, where the image comprises at least two groups of testing charts regarding different positions; pre-processing the image to obtain each group of testing charts by separation; calculating and displaying, based on each group of testing charts, a real-time resolution value of a camera photosensitive surface to each group of testing charts in real time; and adjusting the installation angle of the optical axis of the camera lens relative to the camera photosensitive surface in real time based on the real-time resolution value of the camera photosensitive surface to each group of testing charts.
