Intelligent calligraphy teaching method and system

Abstract

The invention discloses an intelligent calligraphy teaching method and system. According to the specific implementation scheme, a six-degree-of-freedom calligraphy action track is obtained, the form of a calligraphy action track line sequence is stored as a track matrix, and a 9-dimensional action feature vector is constructed and stored; carrying out segmentation preprocessing on the six-degree-of-freedom calligraphy action track, and allocating a unique index to each preprocessed stroke and stage; performing multi-stage time sequence alignment on the calligraphy action tracks of the user and the expert after segmentation preprocessing, adjusting a weight ratio according to core features of different writing stages, calculating local errors and global errors of the calligraphy action tracks of the user and the expert through an improved DTW algorithm, and extracting key difference points; and matching the key difference point with a preset library, judging an error type and evaluating an error level, and triggering multi-level real-time differential feedback. The problems of lack of dynamic writing action teaching and insufficient feedback errors in the prior art can be effectively solved.
