This research aims to develop a pedestrian's intelligent transport system (PITS) for convenience and safety of the pedestrian based on ubiquitous and wearable computers techniques and cooperative distributed vision techniques.In 2001, we developed two components of PITS. One is the supporting system of the blind, that is, Intelligent Cane, and the other is a ubiquitous computing system to obtain and visualize traffic flow of Pedestrians. Intelligent cane has a rangefinder consisting of three laser pointers and one CCD camera, and estimates a situation of floor before the user with the use of measurement results of distance. The ubiquitous computing system to sense and visualize streams of pedestrians consists of street terminals to obtain size and direction of streams of pedestrians, and information integration terminal to visualize obtained streams information on a street map.In 2002, we developed a new location-awareness system that automatically detects and tracks the location of users and identifies the users to connect between street terminal and user's wearable computer. This system consists of two components, sensing systems of user position with fish-eye lens installed CCD camera and IR tags indicating user's position. Our developed this system is capable of managing information of two or more users in real-time process and recovering from the tracking error because of visual occlusion and so on.

本研究旨在基于泛在可穿戴计算机技术和协同分布式视觉技术开发行人智能交通系统(PITS)，以方便和安全行人。一个是盲人的支持系统，也就是智能手杖，另一个是获取和可视化行人交通流量的泛在计算系统。智能手杖有一个由三个激光指示器和一个CCD摄像头组成的测距仪，利用测距结果在用户面前估计地面的情况。用于感知和可视化行人流的泛在计算系统由获取行人流大小和方向的街道终端和将获取的流信息可视化在街道地图上的信息集成终端组成。2002年，我们开发了一种新的位置感知系统，该系统自动检测和跟踪用户的位置，并识别用户以连接街道终端和用户的可穿戴计算机。该系统由两部分组成：安装有CCD摄像机的鱼眼镜头的用户位置感知系统和指示用户位置的红外标签。我们开发的该系统能够实时管理两个或多个用户的信息，并能从视觉遮挡等原因导致的跟踪误差中恢复。
