Embodiment Construction

[0033] The present invention provides a method for detecting movement of environmental changes. The present invention will be further described below in conjunction with examples and accompanying drawings, but the present invention is not limited.

[0034] The following takes the mobile detection of environmental changes under the Linux platform as an example, and the specific instructions are as follows:

[0035] Realizing the mobile detection function under the linux environment provided by the present invention includes the following modules:

[0036] (1) Camera initialization module

[0037] Connect the USB camera, start the corresponding camera driver, allocate space for the object and initialize it after successful connection, and allocate storage space for the picture to be compared at the same time, and set the resolution and sampling frequency of the camera as needed;

[0038] (2) Image acquisition module

[0039] Including acquisition and conversion two parts. Acq...

Abstract

The invention discloses a method for movably detecting the environment change, including the steps: changing the collected pictures in the YUV form into the RGB form, then dividing the picture in the RGB form into 10*10 pieces, comparing the difference of the picture at the same place on four aspects: R, G, B and brightness, when the difference is larger than the corresponding predetermined value, the environment is changed. The method has higher precision on the detecting the environment change, improves the computing efficiency, greatly reduces the computing complexity, which is suitable for the household video monitor.

Description

technical field [0001] The invention relates to a method for mobile detection of environmental changes, which belongs to the field of security and also belongs to the field of information. Background technique [0002] In the current security video surveillance system, the motion detection and alarm of the image sequence can not only replace part of the work of the surveillance personnel, improve the automation level of the surveillance system, but also improve the efficiency of surveillance storage. The digital video monitoring system automatically detects the motion of the image sequence. Once the size and speed of the moving object (most of which are human targets) meet certain conditions, an alarm signal is sent to notify the monitoring personnel to take timely and effective processing. This greatly reduces the visual burden on the surveillance personnel. Most of the digital monitoring systems have storage modules, which can continuously store the image data of the moni...
