Abstract:

This report summarizes the Phase 1 developments of Zaxel Systems, Inc. on award DAAH01-00-C-R058, Voxel-based Immersive Environments. The overall objective of Phase 1 was to demonstrate the feasibility of real-time voxel-based immersive visualization by achieving four objectives Demonstrate voxel-based 3D reconstruction at 3 frames per second Demonstrate interactive view generation at 3 frames per second Determine communication bandwidth requirements and potential compression strategies Understand complexity of adding audio. Zaxel successfully achieved each of these objectives. As part of the resulting system, we developed a collection of additional hardware and software to address technical requirements that must be met for the algorithms to work successfully. These include Multi-camera, multi-PC video capture with recording capability Required synchronization of video across multiple PCs, as well as extensive efforts to support streaming of video to hard disk. Recording video is important for accurately comparing different algorithms and implementations to on another Camera calibration Developed calibration object, procedure, and software to determine 3D relationships among cameras. This capability is necessary to fuse information from multiple view points.
