Photographing device and image acquisition method

Abstract

The invention discloses a photographing device and an image acquisition method. The photographing device comprises at least one photographing unit, a detection unit, a recognition and comparison unit and a processing unit, wherein the photographing unit is used for capturing an image; the detection unit is used for detecting at least one face image or at least one plate number image in the image, the face image is detected if the speed of a vehicle is zero per hour, the plate number image is detected if the speed of the vehicle is larger than zero per hour, and the distance between the face image and a vehicle is determined according to the position of the face image in the image; the recognition and comparison unit is used for recognizing at least one vehicle number from the plate number image, the vehicle number is compared with at least one second number in a database, and a correspondence signal is generated if the vehicle number corresponds to the second number; the processing unit is used for storing the image in a storage unit when the correspondence signal is received and the distance accords with a preset value. By the adoption of the photographing device and the image acquisition method, the vehicle number relevant to a crime can be inspected, and the whole process that a suspect is arrested by police can be recorded.
