    摘要:

    以交通标记识别为例,针对不规则形状识别提出一种新的方法。选取不规则形状的边缘点做双向投影变换,根据归一化和中心化后的投影序列数据求得加权质量,从而得出投影序列的质心。由于相似质点系的质心距离相近,因此相似投影序列的质心也相近。以棋盘距离和街区距离的线性组合替代欧氏距离来度量投影序列及其质心的相似性,继而得到不规则形状的相似程度。实验结果表明,该算法在保持较高识别精度的同时,运算速率也比较快。

    Abstract:

    This paper presents a new method for irregular shape recognition based on traffic sign recognition. The projection sequence is obtained by the bidirectional projection transformation of the irregular edge points. The weighted mass is obtained according to the normalized and centered projection sequence data, and the centroid of the projection sequence is obtained. Because the centroid distance of the similar particle system is similar, the centroid of the similar projection sequence is similar. By using the linear combination of the chessboard distance and the block distance to replace the Euclidean distance to measure the similarity of the projection sequence and its centroid, and then get the similarity degree of the irregular shape. The experimental results show that the algorithm has high recognition accuracy and fast computation speed.
