摘要
本文设计基于全息投影技术的体感互动控制系统,有效控制用户体感互动操作过程。通过全息投影显像模块利用高速多分幅激光全息投影仪,感应用户操作手势及场景,获取用户及场景的激光全息图片,成像单元依据全息图片,利用金字塔结构获取用户及场景的全息影像;经由无线通信模块传输至体感互动控制模块,依据三维全息影像,建立手指几何模型,识别手指触碰投影面的状态,通过触碰投影面完成互动控制;利用体感互动面呈现互动画面。实验证明:该系统可有效构建用户及场景的全息影像,并有效控制体感互动操作过程;不同光束波长时,全息成像颜色效果较优。
A motion sensing interactive control system based on holographic projection technology is designed to effectively control the us-er's motion sensing interactive operation process.The power module provides power for the system.The running process of the system is controlled by field programmable gate controller.The holographic projection imaging module uses the high-speed multi-amplitude laser holographic projector to sense the user's gestures and scenes,and obtain the laser holographic images of the user and the scene.The imaging unit uses the pyramid structure to obtain the holographic images of the user and the scene accord-ing to the holographic images.It is transmitted to the motion sensing interactive control module by wireless communication mod-ule.According to the three-dimensional holographic image,the module establishes the geometric model of finger,identifies the state of finger touching the projection surface,and completes the interactive control by touching the projection surface.It uses so-matosensory interaction surface to present interactive images.Experimental results show that the system can effectively construct the holographic image of the user and the scene,and effectively control the motion sensing interactive operation process.The col-or effect of holographic imaging is better when the beam wavelength is different.
