Problems solved by technology

The single-area processing mode can meet the general needs, but it cannot meet the application requirements of sub-area motion detection under high-definition surveillance where the camera monitoring area is large.
In addition, the single-area processing mode uses the same set of parameters for motion detection processing day and night, which will relatively cause large false positives and false positives

Abstract

The invention relates to the field of video surveillance, and discloses a method and device for motion detection processing. In the present invention, the steps include: presetting at least two detection areas in the shooting range of a camera; switching the current mode to day mode or night mode according to the preset day and night switching control mode and the corresponding switching threshold; Read the motion detection parameters corresponding to the current mode from the motion detection parameters of each detection area; judge whether a motion detection event occurs in the image captured by the camera in each detection area according to the read motion detection parameters . In the present invention, multiple detection areas are set for motion detection, which can meet the application requirements of large camera monitoring area and sub-area motion detection under high-definition surveillance. At the same time, each detection area supports the setting of two sets of motion detection parameters for day and night according to the specific scene requirements of day and night, which can make motion detection achieve the minimum false alarm rate and false negative rate.

Description

technical field [0001] The invention relates to the field of video surveillance, in particular to a method and device for motion detection processing. Background technique [0002] Digital Video Recorder ("Digital Video Recorder", referred to as DVR) is a computer system for image storage and processing, which has the functions of long-term video recording, audio recording, remote monitoring and control of image / voice. [0003] Network video server ("Digital Video Server", referred to as DVS), also known as digital video encoder, is a professional network transmission device that compresses and processes audio and video data. It mainly provides video compression or decompression functions to complete image data collection or Restoration etc. [0004] Motion detection ("Motion detection technology"), also called motion detection in general, is often used in unattended surveillance video and automatic alarm. The images collected by the camera according to different frame rat...
