Title: METHOD AND DEVICE FOR DETERMINING POSITION OF A TARGET
Abstract:
Method and device 100 for determining a position of a target 142 is disclosed herein. In a described embodiment, the method includes sequentially directing each of a plurality of lighting patterns at the target 142, each lighting pattern comprising a plurality of illuminations from respective ones of a plurality of emitters 108, receiving, at a plurality of sensors 118, reflected illumination of each lighting pattern as reflected from the target 142; and determining the position of the target 142 using the reflected illuminations of the lighting patterns and a first classifier previously trained to associate the reflected illuminations to a position of the target 142. In the method, each lighting pattern differs from other lighting patterns by at least an intensity of one of the illuminations; and the intensity of the illumination from at least one emitter is variable between more than two levels. A method of training a classifier for use in the method is also disclosed.
