【摘要】 手绘草图识别技术是计算机支持的交互式草图设计系统中的核心问题,针对这一问题,提出了一种手绘草图识别算法,主要包括手绘草图原始笔划的数据前处理、基于多次检测算法的特征点识别、草图分段识别、空间位置解释、图形重构等内容.本文利用多次识别算法,可以有效解决手绘草图模糊性及拐点和折点不确定性,基于这一技术的三维草图CAD建模方法已在自行研发的CAD软件中得到应用,并取得了良好的效果.更多还原

【Abstract】 The technology of recognition of Freehand Sketch has become the most important problem in the interactive design system supported by computer.This paper presents a method of recognition for freehand sketch,it includes the disposal of original data of freehand sketch,the characteristic points detection based on the recognition algorithm,the recognition of section,the space position analysis,the reconstruction of model and graphics.The method of multiple recognition is an effective solution for ambiguity and uncertainty sketch.The methods of this paper has been applied in the CAD software of Sketching system,with promising effect.更多还原
