The embodiment of the invention relates to the technical field of intelligent security, and discloses a multimedia file retrieval method. The multimedia file retrieval method is applied to a network attached memory device, the network attached memory device is used for storing multimedia files, the method comprises: by receiving a voice retrieval instruction, according to the voice retrieval instruction, determining a reference image, in accordance with the reference image, determining a target image conforming to the voice retrieval instruction from the multimedia file, intercepting video segments of a preset time period including the target image and storing in a destination folder, wherein when one of the video segments includes two or more of the target images, the interval time between two adjacent target images is less than a preset time threshold. The invention realizes automatic, efficient and accurate multimedia file retrieval.
Description
technical field [0001] The embodiment of the present invention relates to the field of intelligent security technologies, and in particular to a multimedia file retrieval method. Background technique [0002] Intelligent security technology refers to the informatization of services, image transmission and storage technology. With the popularization and application of Internet of Things technology, the city's security has evolved from a simple security protection system in the past to an urban comprehensive system. [0003] Multimedia files are an important source of information for intelligent security. To achieve intelligent security in an area or a system area, for example, to analyze road flow information, vehicle location information, public facility safety information, weather information, etc. in a certain section of a road must be real-time Collect or store a large amount of multimedia file information. Due to the huge amount of computing data and high security requi...
