Abstract

The invention discloses an intelligent video monitoring system based on a DirectShow technology. The intelligent video monitoring system comprises a DirectShow component module, a video display set module, a motion object detection module and a data coding compression module, wherein the DirectShow component module is used for setting up an original video flow link, capturing an original video flow, and dividing the original video flow; the video display set module is used for setting an image display picture format, and returning the image display picture format to the DirectShow component module to display in real time; the motion object detection module is used for detecting a motion target in a monitoring area, transmitting image data including the motion target to the DirectShow component module to store the image data as a video file and give an alarm, and otherwise, automatically abandoning image data not including the motion target; and the data coding compression module is used for performing subsequent coding compression and storage of the video file stored by the DirectShow component module, and deleting the original video file. According to the intelligent video monitoring system disclosed by the invention, the technical problem that a video monitoring system, which is simple to develop and relatively high in accuracy, is lacking in engineering practices can be solved; and furthermore, the intelligent video monitoring system has the advantages of being low in cost, rapid in calculation speed and better in real-time performance.

Description

technical field [0001] The invention belongs to the technical field of intelligent monitoring, and in particular relates to a video monitoring system. Background technique [0002] DirectShow is a development kit for streaming media processing under the Windows platform. It can accept data streams from different data sources, process different media formats, and has the ability to interact with underlying hardware devices and high-level application software. Since Windows 7, it has been compatible with The Windows SDK is packaged and released together. DirectShow provides an open development environment, and developers can customize filter components and expand functions according to their needs. [0003] ffmpeg is a very powerful open source framework for multimedia audio and video encoding and decoding, which can realize audio and video stream acquisition, recording, encoding, decoding, conversion, etc. It provides many open source libraries, which can be compiled and run...
