Abstract: A false positive elimination method includes: analyzing a target object to obtain an encryption feature and current position information of the target object; acquiring current image information of the target object, and comparing local historical image information with the current image information to obtain a comparison result; detecting the current image information according to the current position information when the historical image information is inconsistent with the current image information, and sending the encryption feature to a cloud when the target object is detectable in the current image information, so that the cloud determines actual position information of the target object based on the encryption feature; and acquiring the actual position information, verifying the target object based on the actual position information, determining the target object as a false positive object in response to the passed verification, and performing a false positive elimination operation on the false positiv

Abstract: Disclosed in the present application are a sound detection method and apparatus, an electronic device and a computer-readable storage medium. The method includes: acquiring audio and video data about a target object, and extracting and obtaining audio data and image data from the audio and video data; performing feature extraction on the audio data and the image data respectively to obtain an audio feature and an image feature; inputting the audio feature and the image feature into a sound source positioning model for processing; and, when the sound source positioning model outputs a sound source positioning image about the target object, identifying the sound source positioning image and the audio feature by using a multi-modal feature fusion model, and determining whether target audio of the target object exists in the audio and video data.

Abstract: Provided is a remote control device based on computer vision technology, the remote control device includes a main body and a stand base connected with the main body. The main body includes a control unit, an output unit, a power supply unit, and a switch at least partially enclosed by a case. The control unit includes a visual sensor that collects image information and a microcontroller that outputs a control instruction to a controlled device via the output unit according to the image information collected by the visual sensor. The power supply unit is configured to supply power to the control unit and the output unit. The switch is configured to control the working state of the remote control device.
