| 摘 要： | 为了实现超大范围的目标监控与测量,设计和分析了一种基于鱼眼镜头的超广角监测系统。以鱼眼镜头和CCD作为图像采集系统,以DSP作为控制和处理中心,采用自适应动态更新背景差方法进行目标识别,利用图像处理方法进行目标方位角测量,对前方半球空间中可能出现的目标进行监测。实验结果表明,基于鱼眼镜头的监控系统具有超大的监控视角,在各种环境下都具有较高的监控能力;基于动态更新背景的背景差目标识别方法具有较强的抗干扰性,能准确地识别出各种可能出现的目标,并能对其进行方位角测量。相对于传统的监控系统来说,具有监控范围大,结构简单,工作稳定可靠,在各种安全监控领域有着广泛的应用。

| Abstract: | A novel object detection and survey system is designed based on the fish-eyes lens which has an ultra wide range.The fish-eye lens and CCD is used as the image gathering system,the high speed DSP is as the control and processing center.The system uses the algorithm of auto-adapted renewal background subtraction to pick-up the moving object from the image,and uses the algorithm of image processing to survey the azimuth.The experiment indicates that the system has high monitoring ability under each kind of en... |
