Paper Abstract

In this paper we describe an approach and present results from a recently developed system that produces video-rate, 3D maps of the image space using a scanning laser configuration and a patented micro-channel plate intensified detector. The scene is viewed from a separate location to provide depth information via triangulation. The detector provides an estimate of position of the apparent landing spot of the laser beam for each scan angle from which a depth estimate is calculated. The system is designed to scan an approximate 15 X 15 degree field-of-view at distances from 1.5 to 2.5 meters with a resolution of 1.5 cm at rates of 10 - 30 full images per second, and can accommodate range gating to reduce scattered light interference.
