Method and system for optical user recognition
First Claim
1. A method for operating a premises management system, the method comprising:
- capturing, at two or more different sensors communicatively coupled to a device, a sequence of patterns of radiation reflected from a first object in a room over a first period of time, wherein the two or more different sensors are selected from the group consisting of;
red-green-blue (RGB) imaging cameras, RGB depth (RGB-D) cameras, complementary metal-oxide semiconductor (CMOS) image sensors, and infrared imaging sensors;
determining, at a processor communicatively coupled to the device, a sequence of variations between the sequence of patterns of radiation captured by the two or more different sensors and a sequence of patterns of radiation emitted by the device;
determining, at the processor, a first series of object characteristics of the first object over the first period of time based upon the sequence of variations, the first series of object characteristics comprising a sequence of dimensions of the first object, the sequence of locations of the first object, and depth information of the first object;
determining, at the processor, the first object is a user based upon comparing the depth information of the first object, the sequence of dimensions of the first object, and a sequence of locations of the first object to a previously captured second series of a second object characteristics comprising depth information of the second object, a sequence of dimensions of the second object and a sequence of locations of the second object stored in a room profile of the room; and
controlling, at the processor, the premises management system to change a security setting based on the determination that the first object is the user based on the sequence of the dimensions and the sequence of locations of the first object being consistent with the change of the security setting, so that the user can enter the room without the premises management system outputting an alarm.

Abstract
A method and system for optically detecting a user. A sequence of patterns of radiation reflected from an object in a room may be captured by a device. The patterns of radiation may be infrared radiation emitted from the device. A sequence of variations between the captured sequence of patterns of radiation and the emitted sequence of patterns of radiation may be determined and object characteristics of an object may be determined based upon the sequence of variations. The object characteristics may be a sequence of dimensions of the object and a sequence of locations of the object. The method may determine the first is a user based upon the determined object characteristics and a room profile. The room profile may include a plurality of object characteristics of one or more objects in the room.
