The invention relates to a simulation writing brush gesture measuring device on the basis of MEMS, and belongs to the technical field of virtual drawing. The simulation writing brush gesture measuring device comprises a MEMS inertia measuring unit, a microprocessor, wireless transmission equipment, and a battery; wherein the MEMS inertia measuring unit, the microprocessor, the wireless transmission equipment, and the battery are arranged in the pen-holder of the stimulation pen along the pen-holder direction; the MEMS inertia measuring unit is a gesture measuring unit, and connected to the microprocessor; and the microprocessor is a data processing unit, and connected to the wireless transmission equipment. A user uses the simulation writing brush to carry out virtual drawing on a laptop, when the simulation writing brush rotates around a vector in space, the measuring device directly outputs a quaternion which depicts the gesture change of the simulation writing brush, then a new gesture vector of the simulation writing brush is obtained through a geometric transformation calculation, and the new gesture vector is transmitted to the laptop through the wireless transmission equipment and applied to virtual drawing so as to replay the actual draw process.
Description
technical field [0001] The invention belongs to the technical field of virtual drawing, in particular to a MEMS-based simulation brush attitude measuring device. Background technique [0002] In the process of calligraphy and painting, brush gesture is one of the important factors affecting the effect of calligraphy and painting. Therefore, how to measure the posture of the simulated brush is the key in the process of virtual drawing. Nelson S.H.Chu et al. in the literature "Nelson S.H.Chu, Chiew-Lan Tai.
