Abstract:
1. A method of determining a location of a camera within an interior space comprising: receiving, by one or more processors, a first image captured by the camera; identifying, by the one or more processors, two different portions of the first image associated with a first object and a second object within the space, wherein the first object defines a first contiguous surface extending to a first edge and the second object defines a second contiguous surface extending to a second edge, and wherein the portions are identified by comparing visual characteristics of the portions with visual characteristics known to be associated with each of the first and second objects; identifying, by the one or more processors, based on visual information contained within the portions of the first image displaying the first and second objects, a distance between the first edge of the first object and the second edge of the second object; determining, by the one or more processors, a first location of the camera based on a comparison of the sizes and shapes of the portions of the first image associated with the first and second objects and the distance between the first edge of the first object and the second edge of the second object; providing, by the one or more processors, information based on the first location of the camera; receiving, by the one or more processors, a second image captured by the camera, the second image having at least one portion associated with at least one object, wherein the at least one object is smaller in size than the first and second objects; determining, by the one or more processors, a second location of the camera based at least on visual information contained within the at least one portion, the second location being more precise than the first location; and providing, by the one or more processors, information based on the second location of the camera.
