摘要:

提出了在集装箱号码识别中,采用由下至上的字符定位分割识别思路,在具体的课题中对哈夫变换的直线方程和参数数组结构提出了一种优化思路,引进模糊数学中的“接近”概念来找到集装箱序列号码所在的直线方程,排除多余候选字符块,减少了计算量,缩小了所需的运算存储空间,在实际应用中取得很好的效果。

关键词: 集装箱号码识别, 哈夫变换, 直线方程, 数组, 接近度

Abstract:

Textual data on the container is very important in the management of container .This paper uses down-toup thread of thought to find the text of container , and uses Hough Transform to confirm the letter block of container number.In the operation , the paper mends the equation , array of parameter etc .of Hough Transform and introduces the “nearness” into the algorithm according of block instead of point .In applications , it can reduce calculation and the space needed effectively

Key words: recognition of container number, Hough transform, function of line, arrays, nearness
