| 摘要: |
| 针对以往“角方向对几何”同类技术［6～8］提出了新的基于直线基元的几何不变特征关系，并使用该关系针对目标线集建立特征关系多维直方图，作为目标的几何不变特征，通过多维直方图匹配进行目标识别。实验证明该模式关系对于较规则的形体，其检测精度优于以往方法，可用于基于内容与结构的图像分析与目标识别系统中。 |

| Abstract: |
| The paper presents a newly defined pairwise geometric［6～8］ invariant relationship of the line segments of the shape targets based on the formal work of this technology. The method recognizes the targets by comparing the multi-dimensional histograms which are formed by the newly defined invariant relationship. The experiments show that the new relationship is more accurate for regular shape recognition than the old methods. |
