Abstract�� A method of two-dimensional sketch recognition based on incremental mode was proposed according to the characteristics of gesture interaction inpen-based three-dimensional modeling technology. The sketch recognition includes: on-line stroke recognition and conversion, automatic constraint catching and appending, two-dimensional combined entity recognition and rectification, feature gesture recognition and three-dimensional feature modeling. Three-dimensional feature modeling thinking and intelligent reasoning technology based on context-aware were used to the recognition. Feature information for three-dimensional modeling was distilled step-by-step from disorganized and inaccurate two-dimensional sketch. The complexity and accumulative uncertainty are reduced effectively by the method. Feature gesture was mapped into three-dimensional space according to implicit mapping mechanism to finish three-dimensional modeling in real time. Asa result, two-dimensional freehand sketch and three-dimensional accurate modeling are integrated effectively. It has been validated in a prototype system, PenSketch3D, with promising effect.
