本文描述了工程图中多向字符串的分割方法,提出一种新的高精度字串的迭代定向算法,有效地解决了倾斜短字串的方向纠正。同时对字线相交时的推理分割方法也作了介绍。研究中使用了图象形态分析的方法,直接在原图象上进行整体识别,保证了图象信息的完整性和可检测性。

This paper int roduces the segmentation method of omnirange st ring. The iteration al2 gorithm of high accurate st ring directional determination is supplied which solved the direction correction for the short length st ring recognition ,and the ratiocination segmentation algorithm is also int roduced when the st ring is intersected with the line. We use the morphology analysis method to make complete recognition and ensure the integrity and the detectable property of the image information on the original image.
