项目摘要

In this project, we investigated new camera systems and image processing methodologies. Firstly, we proposed and developed a new camera system made of array of sensors that enabled simultaneous capture of both wide angle and dose up views. A prototype system was developed and it was evaluated in indoor experimental setup.Next, a multi-camera surveillance system was designed to be used in general outdoor environment. A single system was extended to multiple systems and their communication is provided by general wireless LAN. A single system was designed to use three cameras n order to capture wide angle views with sufficient details instead of a single camera with mechanical pans and zooms. A single PC was assigned to the system of three cameras for capture and processing of person tracking and video compression. In total 12 systems with 36 cameras and 12 PCs were built and they were connected by wireless LAN. Although wireless LAN has some amount of bandwidth, it is not enough for tran … More smission of a number of videos. Then, we developed content-aware compression scheme to send videos to a remote server.. In the compression scheme, significant compression is achieved even by changing size of images.Below is the list of the achievements of this project.> Camera array for simultaneous capture of wide-angle and close up views without mechanical controlCamera array made of random access CMOS sensors were built and the functions of simultaneous capture of wide angle and close up views were examined.> A generic system with three cameras for outdoor surveillanceThree cameras and a PC connected by wireless LAN is designed. It covers wide angle with sufficient details.> Highly efficient video transmission for the designed surveillance systemContent-aware control of video compression was designed and implemented. Bit allocation making use of the distributed nature of the surveillance camera was also designed.> Real life experiments12 systems made of 36 cameras and 12 PCs were in operation. A large size outdoor experiments were conducted. Less

在这个项目中，我们研究了新的摄像系统和图像处理方法。首先，我们提出并开发了一种新的摄像机系统，该系统由多个传感器阵列组成，可以同时捕获广角和剂量视图。开发了一个原型系统，并在室内实验环境中对其进行了评估。其次，设计了一个适用于一般室外环境的多摄像头监控系统。将单个系统扩展到多个系统，它们之间的通信由通用无线局域网提供。一个单一的系统被设计成使用三个摄像头来捕捉足够细节的广角视角，而不是一个带有机械平移和变焦的单一摄像头。一台个人电脑被分配给由三个摄像头组成的系统，用于捕获和处理人员跟踪和视频压缩。总共搭建了12个系统，36个摄像头和12台PC，通过无线局域网连接。虽然无线局域网有一定的带宽，但对于TRAN…来说是不够的一些视频的爆发力更强。然后，我们开发了内容感知压缩方案，将视频发送到远程服务器。在压缩方案中，即使改变图像的大小，也能获得显著的压缩效果。以下是本项目的成果。&gt；无需机械控制即可同时捕获广角和近距离图像的摄像头阵列。构建了由随机访问的cmos传感器组成的Camera阵列，并测试了同时捕获广角和近距离图像的功能。&gt；一个通用的三摄像头户外监控系统设计了三个摄像头和一台PC通过无线局域网连接。针对所设计的监控系统，设计并实现了内容感知的视频压缩控制。还利用监控摄像机的分布式特性设计了比特分配。&gt；现实生活实验由36个摄像机和12台PC组成的12个系统正在运行。进行了大规模的室外实验。较少
