Abstract
The disclosure provides for a scanning apparatus. The scanning apparatus may be configured to capture identifying information of a user and may comprise one or more infrared emitters, at least one image sensor configured to capture image data in a field of view, and a controller in communication with the scanning apparatus. The controller may be configured to activate the one or more infrared emitters, control the at least one image sensor to capture a first image in the field of view, deactivate the one or more infrared emitters, and control the at least one image sensor to capture a second image in the field of view.
Claims11
A scanning apparatus configured to capture identifying information of a user comprising:
- one or more infrared emitters;
- at least one image sensor configured to capture image data in a field of view;
- a concealment apparatus configured to selectively mask or hide the scanning apparatus in a concealed configuration and reveal a location of the scanning apparatus in a scanning configuration;
- and
- a controller in communication with the scanning apparatus, wherein the controller is configured to:
- activate the one or more infrared emitters;
- control the at least one image sensor to capture a first image in the field of view;
- deactivate the one or more infrared emitters;
- control the at least one image sensor to capture a second image in the field of view;
- compare the first and second images;
- determine a set of pixels having a change from the first image to the second image;
- subtract the set of pixels having the change from the image data in the field of view to determine a location of the user;
- and
- process the set of pixels for identification of the user.
