METHOD AND APPARATUS FOR MONITORING AN OBJECT

摘要

The present invention relates to a method of monitoring an object and in particular, but not limited to, monitoring a change in configuration of a person. The method includes projecting a pattern of radiation onto an object for monitoring; recording at a first instant in time first image data representing at least a portion of the projected pattern of radiation on the object, the first image data being representative of a three dimensional configuration of the object at the first instant in time; recording at a second instant in time second image data representing at least a portion of the projected pattern of radiation on the object, the second image data being representative of a three dimensional configuration of the object at the second instant in time;and processing the first and second image data to generate differential data representative of a change in the configuration of the object between the first and second instants in time. The present invention further relates to an apparatus and software for implementing a method in accordance with the present invention
