ON A VISUAL AID SYSTEM USING 3D CAMERA AND ACOUSTIC METHOD

为了实现视障人士的视听辅助系统，利用3D声学处理机进行了基础研究。该系统通过耳机声学地显示3D声音，对应于待捕捉障碍物的位置。为了评估这种声学系统，还在虚拟空间中进行了BSIC研究，其中被认为存在障碍物。在这项基础研究中，受试者使用操纵杆进行虚拟移动，操纵杆再次垂直移动摄像头的位置。在实际空间中，受试者佩戴头盔摄像头，最终捕捉到障碍物，然后发出与障碍物位置对应的声音。结果表明，该方法对到达和捕捉障碍物是有效的，即使需要的时间比预期的要少，这需要使用高速计算机来减少。

Towards a realization of an acoustic visual aid system for the visually impaered, a basic studies were made using 3D acoustic sound processor. The system displays acoustically through the headphone 3D sounds which corresponds the localization of an obstacles to be catched. To evaluate such acoustic system, a bsic study was made also in a virtual space, where an obstacle is thought to exist. In this basic study, the subjects moves virtually using ajoystic bar, which moves camera position viratually again.In actual space, the subjects wears a headmount camera, which catches the obstacles at last before generating sounds corresponding the position of the obstacles. The over all results show that this method is effective to reach and to catch an obstacles , even the time is necessary than expectation, which shall be reduced using high speed computers.
