First Claim
Patent Images
1. A method of monitoring a building comprising:
- taking a video within a location in the building with a video sensor, the video comprising a plurality of frames, each frame including image data;
for each frame, receiving depth data associated with the image data, the depth data corresponding to one or more distances from the video sensor to features represented by the image data;
analyzing the image data and depth data to detect and classify one or more objects depicted in the video, classification of the one or more objects comprising determining whether at least some of the one or more objects are people;
counting a number of people based on the analyzing of the image data and the depth data; and
controlling a system of the building in response to the number of people counted.

Abstract
A method and system for monitoring buildings (including houses and office buildings) by performing video content analysis based on two-dimensional image data and depth data are disclosed. Occupation and use of such buildings may be monitored with higher accuracy to provide higher energy efficiency usage, to control operation of components therein, and/or provide better security.. Height data may be obtained from depth data to provide greater reliability in object detection, object classification and/or event detection.
