【摘要】 基于细化的识别处理算法是工程图自动识别处理中使用较为广泛的一种技术，然而，目前的细化过程会在节点处产生畸变而导致最终的识别率较低。本文对细化后畸变节点形态进行了深入地分析，讨论了产生畸变的原因，并提出了有效地抑制细化后节点畸变的修正策略，所提出的修正方法已成功地用于解决实际问题。更多还原

【Abstract】 Thinning based recognition algorithms are widely used in the field of automatic processing of engineering drawings. However, the current thinning processes perform out of shape at the node, which result in relatively low recognition rate of the primitive graphic elements. The node patterns after thinning are deeply analyzed, and the reason producing node deformation is discussed. A node regulation strategy which can effectively revise the deformation of node created in the thinning procedure has been proposed. The algorithm proposed in this paper has been applied to solve the practical problem successfully.更多还原
