Summary: | The invention relates to a three-dimensional handwriting recognition method based on direction chain code and belongs to the field of human-computer interaction. The method includes: building a three-dimensional handwriting model by collecting spatial position information of a pen in a handwriting input passage and adopting direction chain code to describe moving track of the pen; matching the three-dimensional handwriting model with a set model in a system to recognize interaction intention of a user in real time. The method can recognize some handwriting operations of the user in three-dimensional space in real time, has certain universality and expandability and is supportive of three-dimensional book space recognition, and naturality of a human-computer interaction platform is improved. A coding mode through the direction chain code is applied, so that the method is simple and convenient in algorithm, small in calculation amount and high in instantaneity; accurate recognition can be realized by denoising |
