Abstract

The invention proposes a sketch semantic recognition method and a sketch semantic recognition system for on-line capture of design intent. The method comprises the following steps of: building a relation model between sketch drawing rule and the design intent; drawing a sketch; and performing sketch semantic recognition on the sketch according to the relation model between the sketch drawing rule and the design intent to acquire a design chart matched with the sketch. According to the method, better recognition results can be obtained from the sketches drawn by users of different design thinking and drawing habits, and the method has the advantages of low computation complexity and high recognition rate.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a sketch semantic recognition method and system for capturing design intentions online. Background technique [0002] With the upgrading of product innovation, the conceptual design that determines product innovation is also more and more valued by enterprises, and the design methods and tools that support conceptual design have become an urgent need. The concept design process is not a one-off process. Designers need to go through continuous exploration and brewing, and inspiration will burst out in their minds. After the inspiration arises, the designer expresses it quickly with sketches and constantly revises the sketches. The rapid development of computer technology in hardware and software makes it easy to realize intelligent and conceptual product design. Commercial sketching software adopts WIMP (Windows, Icon, Menu, Pointer) mode of operation, which interrupts the conti...
