In one embodiment, a technique is provided for tracking a mobile device within a building. A course position estimate of the mobile device is determined using a positioning system. The course position estimate indicates a room in which the mobile device is located. One or more sensors of the mobile device capture a live point cloud of surroundings of the mobile device. Tracking software accesses a portion of a pre-captured point cloud of the interior of the building that serves as a reference. The portion of the pre-captured point cloud corresponds to the room indicated by the course position estimate. Once the initial pose is determined, an updated pose of the mobile device is determined when the mobile device is moved, based on a further comparison of the live point cloud to the portion of the pre-captured point cloud.
