OPTICAL NAVIGATION & POSITIONING SYSTEM

摘要

An optical navigation system comprising a camera oriented to face towards a plurality of markers located at spaced apart locations from the camera, calculating means adapted to calculate an angle subtended between pairs of markers, the subtended angles being calculated by monitoring the pixel locations of the markers in a series of images captured by the camera, the optical navigation system additionally comprising means for creating a three-dimensional model whereby the location of the camera relative to the markers is determined by triangulating the subtended angles in the three-dimensional model.

1. An optical navigation system comprising a camera oriented to face towards a plurality of randomly positioned markers located at spaced apart locations from the camera, calculating means to adapted monitor, in a series of images captured by the camera, the pixel locations of the markers, the optical navigation system additionally comprising means for creating a three-dimensional model of the camera's position and orientation relative to the markers by monitoring changes in the relative positions of the markers in the captured images to determine, by monitoring changes in the apparent perspective of the markers that are indicative of changes in orientation and position of the markers.
