1. A method comprising: accessing a plurality of images, each image of the plurality being associated with pose data identifying an orientation of the image with respect to a location at which the image was captured and each image of the plurality having a less than 360 degree field of view; projecting, by one or more processors, a plurality of points onto a circular shape based on the pose data associated with the plurality of images, wherein a center of the shape represents a location at which a panoramic image having a 360 degree field of view was captured and each point of the plurality of points represents a respective one of the plurality of images such that the projected points correspond to the plurality of images on a one- to-one basis; determining, by the one or more processors, an average location of the projected plurality of points around the circular shape; determining, by the one or more processors, a viewing pose identifying a reference orientation for viewing the panoramic image based on the average location of the projected plurality of points; and storing the viewing pose in memory.
