依靠基础设施维护和发展。在本文中，我们概述了使用三维虚拟声音提供三维视觉信息的视觉支持系统的设计。通过分析立体摄像头拍摄的图像，识别视障用户所需的物体，获得三维信息。使用依赖于头部相关传递函数的三维虚拟声学显示器，用户可以获知物体的位置和运动。用户的听觉不会受到阻碍，因为我们使用的是骨传导耳机，不会遮挡环境声音。所提出的系统预计在基础设施不完整以及情况实时变化的情况下有用。我们计划对其进行实验，例如引导用户步行和进行运动。
ly by infrastructure maintenance and development. In this paper, we outline the design of a visual support system that provides three-dimensional visual information using three-dimensional virtual sound. Three-dimensional information is obtained by analyzing images captured by stereo cameras, and recognizing the objects needed by the visually impaired user. Using the three-dimensional virtual acoustic display, which relies on Head Related Transfer Functions, the user is informed of the 1ocations and movements of objects. The user's auditory sense is not impeded as we use a bone conduction headset, which does not block out environmental sound. The proposed system is expected to be useful in the situation where the infrastructure is incomplete, and when the situation changes in realtime. We plan to experiment with it, for example, to guide users in walking and playing sports.
