CMU Video-Rate Stereo Machine

In this paper, CMU video-rate stereo machine based on multi-baseline method is introduced. It is a dedicated hardware for very fast range measurement. A calibration method suitable for multi-baseline stereo is also shown. Finally the performance is demonstrated in an indoor scene. Direct motivation of the development of stereo machine is to use it as a range sensor in autonomous navigation vehicles. But we believe there are many applications that the stereo machine opens up. One interesting application is a 3D scene modeling in which 3D data obtained are combined with intensity/color image to create a 3D model of a real scene. We continue to improve the performance of the stereo machine and plan to develop an application like this.
