| 摘 要： | 针对基于全景视觉系统采集的图像序列中运动目标检测的方法进行了研究,采用三帧差法和混合高斯模型相融合的算法对运动目标进行检测。不但解决了三帧差法无法检测出全部目标信息的缺点,而且还避免了背景减除法容易出现两个目标的假现象,在背景颜色和目标颜色相近时检测效果较好。实验表明,该算法能准确检测出运动目标,具有较好的实时性。

| Abstract: | This essay proposes a method of moving target detection based on omni-directional vision,which detects a moving target by using the three frame difference and the mixture Gaussian model.Not only can it overcome the weakness of the three frame difference model that it fails detect all information of the target,but also it can avoid the false phenomenon of two objectives emerging by the background subtraction method.The effect is much better when the background color is close to the target color.Experimental results show that the proposed method can detect moving objects accurately in real time. |
