Abstract

According to embodiments of the present invention are a system and method that use projected structured patterns of light and linear optical sensors for motion tracking. Sensors are capable of recovering two-dimensional location within the projection area, while several sensors can be combined for up to six degrees of freedom tracking. The structure patterns are based on m-sequences, in which any consecutive subsequence of m bits is unique. Both digital and static light sources can be used. The system and method of the present invention enables high-speed, high precision, and low-cost motion tracking for a wide range of applications.
