根据脉搏动态网格图像数据的特点,结合透镜成像原理.提出了根据各帧图像中网格面积的变化获取脉管径向离面位移信息的方法。应用该方法可获取脉搏图像表面多点离面位移变化信息.并可根据各点位移量对网格薄膜表面进行重构.实现脉搏波动三维信息可视化。
A method of acquiring radial pulse information from the gdd-net area on every pulse image frame is proposed based on the principle of lens imaging and the charactedstics of image data. The radial pulse image data are collected by the pulse image sensor. Multi-points out-of-plane displacements of the pulse are acquired by the method. And the membrane surfaces are reconstructed, then the 3D information of the pulse can be observable.
