Method and apparatus for monitoring an object

摘要

A method and system of monitoring an object (e.g., for change in configuration of a person) includes projecting a radiation pattern onto the object; recording at a first time first image data representing a portion of the projected radiation pattern on the object, the first image data representative of a three dimensional configuration of the object at the first time; recording at a second time second image data representing a portion of the projected pattern of radiation on the object, the second image data representative of a three dimensional configuration of the object at the second 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 times.

主权项

1. A method of monitoring a regional lung function of a person, the method including the steps of:
a) projecting a pattern of radiation onto at least a portion of the person for monitoring; b) recording at a first instant in time first image data from a video camera disposed at a first viewpoint toward said portion of the person, said first image data representing at least a portion of said projected pattern of radiation on the portion of the person, said first image data being representative of a three dimensional configuration of said portion of the person at said first instant in time; c) recording at a second instant in time second image data from said video camera disposed at said first viewpoint toward said portion of the person, said second, image data representing at least a portion of said projected pattern of radiation on the portion of the person, said second image data being representative of a three dimensional configuration of said portion of the person at said second instant in time; and d) processing said first and second image data to generate differential data representative of a change in volume of said portion of the person between the first and second instants in time to determine the regional lung function of the person.
