Claim 0:
1. A method for determining airborne particulate density, said method comprising the steps of:
a) locating or positioning at least one dark target within a local environment;
b) scanning said local environment using an image capturing component of a user equipment device and constructing a geometric three-dimensional model of said local environment;
c) determining pertinent features within said local environment based on said geometric three-dimensional model, said pertinent features including: a relative location of said at least one dark target with respect to said user equipment; and, a relative location and intensity of any light sources within said local environment;
d) focusing said image capturing component of said user equipment device on said at least one dark target, said user equipment device having quantified location and orientation within said local environment;
e) determining an instantaneous light intensity of said local environment and capturing at least one image of said at least one dark target using said image capturing component of said user equipment device, said instantaneous light intensity being obtained prior to capturing said at least one image; and,
f) analyzing 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.
