Abstract (en)
[origin: US2007052697A1] The invention concerns a method and a system for detecting a body ( 801 ) in a zone ( 802 ) located proximate an interface ( 803 ). The body is illuminated by an electromagnetic radiation ( 804 ) comprising at least two different wavelengths, located in ranges corresponding to near infrared and to green-blue. The method comprises the following steps: selecting two wavelengths; providing, for each of said wavelengths, an image ( 805 ) of the interface and of the zone; extracting from said data of each image two sets of data ( 807 ) respectively representing at least one part of the body in the near infrared range and in the green-blue range; comparing said data sets ( 807 ). It is thus possible to detect the presence of a body by discriminating between a body entirely located beneath the interface and a body located at least partly above the interface.
