Abstract
A method and system for locationing of a mobile device () within an environment includes light sources () disposed within the environment and modified to provide a plurality of unique identity patterns () associated with particular locations within the environment. A camera () and image processor () of the mobile device can obtain images of a modified light source () and recognize the unique identity patterns in the image and a horizontal and vertical angle of a position of the light source in the image from a center position. An accelerometer () can capture the gravity vectors of the camera. A locationing engine () can determine a location of the mobile device using the unique optical pattern, gravity vectors, and the horizontal and vertical angles.
