Abstract

We present PositionIt, a novel, low-cost, image-based remote target localization system using commodity smartphones. By leveraging smartphones' built-in sensors such as camera, digital compass, GPS, etc., the system can estimate the distance/position of remote targets. The system also takes advantage of the user-friendly interface of the smartphones to facilitate low complexity implementation (e.g., to locate target of interest and restrict the search area for matching).The feasibility of both single-image and two-image based systems are demonstrated.
