摘要
仪表精度等级符号自动识别是自动校表系统中重要的一部分。介绍采用不变矩和支持向量机识别仪表精度等级符号图像的方法。该方法利用不变矩提取仪表精度等级符号图像特征,利用支持向量机识别仪表精度等级符号图像。实验结果表明该方法具有较好的分类性能。
The automatic recognition of precision ratings symbol is a key part in the meter inspection system. The method of meter precision ratings symbol images recognition based on invariant moments and support vector machine was proposed. In this method, invariant moments were employed to extract features of meter precision ratings symbol images and they were recognized by support vector machine. Experimental results show the proposed method has perfect classification performance.
