摘　　要：在分析序列测量图像目标基本特性的基础上,提出了一种利用测量目标形状的先验信息进行图像目标检测的方法.首先对测量图像进行Hough变换,然后根据已知的目标外形几何关系对变换后所得的直线进行分析,确定包含目标边缘的直线,从而得到目标的准确外形.实验表明:此种方法具有较强的检测能力,尤其对于含噪声较大的图像更加明显.Based on the analysis of the basic characteristics of serial measurement images target, a new method is proposed, using the information before measurement target figure experiment to detect the target image. First, Hough transformation of measurement image is carried out; then the given target shape geometry relation is used to analyze the transformed beeline and then the decision of which line includes aim edge to get the nicety figure is made. It is proved that its detecting ability is enhanced and it has a great effect on the images which has larger noises.
