Method and system for behavior detection

摘要

Described herein are systems and methods for automatically detecting a behavior of a monitored individual, for example, that the individual has fallen. In certain embodiments, a system is presented that includes one energy sensor (e.g., a camera of a mobile electronic device) configured to capture reflected energy (e.g., light) within a field-of view; an optional lens to modify the distance or angular range of the field-of-view; and an optional image obfuscator to blur or distort the images received by the energy sensor, thereby preserving privacy. Techniques are described for determining spatial measurements and body measurements from the images and using these measurements to identify a behavior of the monitored individual, for example, a fall.

1. A method for automatically detecting a behavior of an individual, the method comprising:
capturing a sequence of obfuscated images of a field of view of a mobile electronic device positioned at a height within a predetermined range of acceptable vertical heights and at an angular orientation within a predetermined range of acceptable angular orientations, wherein:
the field of view comprises a space at least occasionally inhabited by the individual, andthe sequence of obfuscated images protects the privacy of the individual; pre-processing the captured sequence of obfuscated images by a processor of a computing device prior to subsequent image processing, thereby altering image data of the sequence of obfuscated images; automatically identifying, by the processor of the computing device, graphical elements of the sequence of obfuscated images corresponding to the individual moving within the field of view of the mobile electronic device; automatically determining, by the processor of the computing device, one or more spatial measurements from one or more obfuscated images of the sequence of obfuscated images; automatically determining, by the processor of the computing device, one or more body measurements (i) from the one or more determined spatial measurements and/or (ii) directly from two or more obfuscated images of the sequence of obfuscated images; and automatically initiating, by the processor of the computing device, an event when the behavior of the individual is detected, wherein the behavior is detected by directly evaluating when at least one of the one or more determined body measurements and the one or more determined spatial measurements exceeds a threshold.
