Title:
OPTICAL NAVIGATION & POSITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/132090
Kind Code:
A3
Abstract:
An optical navigation system (10) comprising a camera (16) oriented to face towards a plurality of markers (26) located at spaced apart locations from the camera (16), calculating means adapted to calculate an angle (θ, φ) subtended between pairs of markers (26), the subtended angles (θ, φ) being calculated by monitoring the pixel locations (26') of the markers (26) in a series of images captured by the camera (16), the optical navigation system (10) additionally comprising means for creating a three-dimensional model whereby the location of the camera (16) relative to the markers (26) is determined by triangulating the subtended angles (θ, φ) in the three-dimensional model.
