METHOD FOR CONTAMINATION DETECTION IN A TOF RANGE CAMERA
First Claim
1. A method for contamination detection in a time-of-flight (TOF) range imaging system, said TOF range imaging system receiving light reflected from a scene, through an optical interface, on an imager sensor having an array of pixels, wherein distance information and amplitude information are determined for said sensor pixels, and wherein the presence of contamination on said optical interface is determined on the basis of said amplitude information determined for said sensor pixels.

Abstract
A method for contamination detection in a time-of-flight (TOF) range imaging system is described, wherein the TOF range imaging system receives light reflected from a scene, through an optical interface, on an imager sensor having an array of pixels, and wherein distance information and amplitude information are determined for the sensor pixels. The presence of contamination on the optical interface is determined on the basis of amplitude information determined for the sensor pixels.
