| Summary: | 碩士 === 國立中央大學 === 資訊工程學系 === 107 === For children, drawing is an interesting and self-expression activity. Drawing is not only fun, but also helps children improve their hand-eye coordination. It could enhance children's visual thinking, creativity and self-confidence. This thesis proposes a drawing scene construction system which is combined with drawing and augmented reality technology. The system uses low-cost and common drawing tools to give children a multi-level experience in painting and visualization.
The proposed system involves in simple operations through the use of a mobile device as a human-machine interface, and combines the drawing scene with the augmented reality technology to make a 2-D painting become a 3-D concrete scene and help children learn abstract concepts and improve children's enjoyment of painting. The system is consisted of four modules: (1) a drawing object recognition module, (2) a rotation angle analysis module, (3) a 3-D model texture generation module, and (4) an augmented reality scene rendering module.
At present, eight kinds of drawing object models have been implemented in the system. Simulation results showed that the average recognition rate of the eight models could reach 89% correct. The field test also showed that the stability of the scene recognition ability based on the augmented reality was about 95%. These testing results demonstrated that the drawing scene construction system can provide accurate recognition and has a good rendering effect.
