Abstract
A mobile platform generates a panoramic map by rotating a camera and stores the panoramic map. The mobile platform performs a computer vision operation on the panoramic map while continuing to generate the panoramic map. The mobile platform may determine the location of the camera when the panoramic map is generated, produce an annotation on the panoramic map and transmit the determined location, annotation, and portion to a storage device. In another example, the mobile platform may receive an annotation, a portion of a source panoramic map associated with the annotation, and a location where the source panoramic map was generated. The mobile platform may compare the portion of the source panoramic map to the panoramic map to identify a position on the panoramic map that corresponds to the portion of the source panoramic map, and display the annotation based on the determined position on the panoramic map.
