摘要本课题设计的是智能化、数字化的图像识别监控报警系统,与传统意义上的模拟图像报警系统的单点触发报警模式有所区别。早期的报警模式是机械、不加分析的发出报警。随着计算机技术和网络技术的发展,数字图像处理技术已经日趋成熟。本设计的特点就是基于数字图像处理技术,以视频监控系统的发展为背景,来设计自动报警。
在硬件上本设计采用CCD摄像头作为输入设备,以图像采集卡作为系统的模数转换设备,计算机作为控制处理设备,软件方面主要通过MATLAB来分析处理。
在监控方面如果有异物进入,就对异物先进行提取随后进行分割测量,利用形态学滤波去除噪声,利用图像配准技术和动态背景运动检测法去除背景噪声,光线等等微弱因素的影响,防止产生误判。分析闯入异物所占整幅画面比例和异物进入的角度与方式因素进行判断,从而决定是否触发报警设备。19909

Title The study of image alarm technology Abstract
The design of this project is intelligent, digital image recognition monitoring alarm systems,differ from the triggered alarm mode used in traditional single-point analog image alarm system.The early alarm mode is mechanical and without analysis. With the development of computer technology and network technology, digital image processing technology become mature gradually.On the backgrounds of the development of video surveillance systems, features of this design is based on digital image processing technology to design automatic alarm.
CCD camera has been used in this design as an input device and image acquisition card is used as analog-digital conversion system equipment, computer equipment is used as the control treatment and the software MATLAB is used to analyze the digital image.
If a foreign body entering in the surveillance,then piding measurement followed by extraction , using image smoothing technique to remove noise and using image registration techniques and dynamic background motion detection to remove the effects of background noise, light, and weak factors in order to not produce false positives. The analysis of the angle and the way to break into foreign objects share the full picture of the scale and foreign matter into the subsequent judgments based on form factor and invariant moments factors to determine whether to trigger an alarm device.
