METHOD AND SYSTEM FOR DETERMINING MOTION PARAMETERS ASSOCIATED WITH AN OBJECT

摘要

The present invention provides a system and method to illuminate a surface of an object with light of at least two distinct colours during distinct sampling periods within an exposure time of an optical sensor and capture light reflected from the surface of the object to generate an image of at least a portion of the surface of the object such that the image includes at least two distinct colour channels capable of distinguishing the at least two distinct colours of the light. Subsequently, a sample pattern is retrieved from each distinct colour channel. Each sample pattern is indicative of a distinct position of the object. The present invention computes the one or more motion parameters associated with the object based on the information embodied in the sample pattern.
