Claim 8:
9. A system for determining airborne particulate density, the system comprising:
one or more dark targets disposed within a local environment; and,
a user equipment device comprising a computer processor and an image capturing component;
wherein said user equipment device has quantified location and orientation within said local environment and is configured to:
a) scan said local environment using said image capturing component and construct a geometric three-dimensional model based on said scans using said computer processor;
b) determine, using said computer processor, pertinent features within said local environment based on said geometric three-dimensional model, said pertinent features including: a relative location of said one or more dark targets with respect to said user equipment; and, a relative location and intensity of any light sources within said local environment;
c) focus said image capturing component on said one or more dark target;
d) determine, using said computer processor, an instantaneous light intensity of said local environment immediately prior to capturing images of said one or more dark target;
e) capture, using said image capturing component, at least one image of said one or more dark target; and,
f) analyzing, using said computer processor, said at least one image in correspondence with said pertinent features, said instantaneous light intensity, and said dark target, and determining therefrom an airborne particulate density in said local environment.
