<p>In this paper we introduce a new real-time parallel image processing system based on an IEEE1394-based PC-cluster. PC-clusters are becoming standard tools in the field of computer vision, especially for real-time multi-view image processing. To reduce the cost of system construction, we have employed IEEE1394 bus as a base network of the PC-cluster. IEEE1394 bus has the throughput of up to 400Mbps, which is large enough to transfer uncompressed video data, and supports not only asynchronous data transfer but isochronous one, which is inevitable for real-time data transfer. In addition, since we have several productsof IEEE1394-based digital cameras, we can easily integrate real-time image processing system including camera systems.</p> <p>This paper presents an overview of our real-time parallel image processing system on an IEEE 1394-based PC-cluster, referring to basic features of IEEE1394. We also show some experimental results to evaluate the performance of the PC-cluster, comparing it with the performance of our previous Myrinet-based PC-cluster. Then we show a prototypical application of the system, which is real-time volume reconstruction from multi-view images by visual cone intersection method.</p>
