Abstract: Provided are an imaging method, an imaging device, a rearview mirror and a storage medium. The imaging method includes: performing spot photometry on a first photometric area of a plurality of photometric areas divided from an image to be tested; and acquiring, according to a result of spot photometry on the first photometric area, a first target image corresponding to the image to be tested. By selecting an appropriate first photometric area to perform the spot photometry and then acquiring the first target image according to the result of spot photometry, the imaging of a target object contained in the first target image would be clearer since the photometric result of a spot photometry is more accurate and is not affected by other areas.

Abstract: The present disclosure provides a positioning adapter, a communication method, an indoor positioning system and an indoor positioning method. The positioning adapter includes: a first communication circuit, an encoder, a second communication circuit and an adaptation interface. The first communication circuit is configured to receive position information, and send the position information as well as identity information to the encoder. The encoder is configured to receive the position information and the identity information, obtain encoded information that matches the smart device by encoding the position information and the identity information, and send the encoded information to the second communication circuit. The second communication circuit is configured to receive the coded information and transmit the coded information to the smart device through the adaptation interface.

Abstract: Provided are a fire alarming method and device. The method includes: acquiring the n types of environmental data of a current moment by the sensing module; determining a fire probability corresponding to each type of environmental data according to the n types of environmental data; determining a fusion probability of the n types of environmental data according to the n types of environmental data and the fire probability corresponding to each type of environmental data; and sending alarm information when the fusion probability is larger than a specified probability value. The fusion probability is the probability determined by comprehensively considering multiple types of environmental data, and the accuracy is relatively high. Therefore, the accuracy of the alarm information is also relatively high, which solves the problem that the accuracy of the alarm information is relatively low, and improves the accuracy of an alarming result sent by the fire alarming device.

Abstract: The present disclosure provides an image rectification method and device and a non-transitory computer-readable storage medium. The method includes obtaining an image to be displayed and a display region of a display screen. The method includes determining a to-be-rectified region of the image to be displayed according to the image to be displayed and the display region. The method includes rectifying the to-be-rectified region of the image to be displayed to make the rectified image to be displayed match the display region.
