摘要
根据烟支的几何特征构造烟支模板,采用一种旋转编码方案将此二维模板映射成为整数集上的一个整数.利用旋转编码描述烟支的属性,通过属性变换得到每组属性的标准编码值.在模板匹配过程中,对模板覆盖下的图像部分作同样的旋转编码及属性变换,得到每组属性的实际编码值.各组属性的标准编码值和实际编码值间的差异将作为制定烟支识别条件的主要依据.实验表明,该方法可解决连通烟支或残缺烟支的计数识别问题,计数精度达到应用需求.
Cigarette template is constructed according to geometrical features of cigarette, and this twodimension template is mapped to an integer with a coding scheme named rotating code. Then rotating code is used to describe the attributes of cigarette, and the standard code of every attribute is obtained by attribute transformation. In the process of template matching, the rotating code and attribute transformation are applied to the sub-image covered by the template. The differences between the attributes codes of the template and those of sub-image are used to establish the cigarette recognition criterions. Experiments show that this method can solve the counting and recognition problem of connective cigarettes and misshapen cigarettes, and the counting accuracy can meet the application requirement.
