DETECTING BODY MOVEMENTS USING DIGITAL COLOUR REAR PROJECTION

摘要

FIELD: physics, optics.SUBSTANCE: invention relates to image processing for analysing an object. A system for analysing an object comprises a background unit placed behind the object to provide a background for the object, wherein the colour of the background unit can be selected from any of a set of colours; a controller configured to automatically determine the colour distribution of the object; determine a colour from the set of colours for the background based on the determined colour distribution of the object, wherein said colour differs from the colour of the object; and set the background colour to said colour; a camera configured to capture an image which includes the object and the background, set to said colour; and a processing unit configured to determine at least one feature associated with the object in accordance with the image captured by the camera.EFFECT: high accuracy and stability of object analysis.20 cl, 6 dwg
