Orientation-based generation of panoramic fields

摘要

A field sensor may be capable of generating a panoramic field, e.g., by instructing the user to capture a sequence of fields of the panorama, performing a field evaluation to identify one or more landmarks depicted in overlapping areas of two contiguous fields, performing a field registration therebetween, and stitching together the panoramic field. However, panoramic field stitching based on field evaluation may fail to register two fields accurately or at all. Rather, panoramic field stitching may be performed using a device having an orientation sensor that detects the orientation of the device while capturing each field with a field sensor. The detected orientation may be used to orient the fields within a projection, from which a panoramic field may be accurately stitched. Additional variations include stitching together projections of the panorama captured at different times and utilizing fields captured at a distance from the root location of the panorama.

主权项

1. A method of generating panoramic fields using a field sensor having a processor, a memory, and an orientation sensor, the method comprising:
executing on the processor instructions configured to:
upon capturing a field:
detect an orientation of the field sensor using the orientation sensor and a location of the field, andstore the field with the orientation and the location of the field in the memory; andupon receiving a request to generate a panoramic field of a subject from a projection using the at least one field stored in the memory:
for the respective fields, orient the field within the projection using the orientation and the location stored in the memory with the field;present the panoramic field of the projection using the fields oriented within the projection; andwhile presenting the panoramic field, upon detecting an availability of a second field depicting the subject from a second location having a nonzero view distance from the projection:
present a view indicator that indicates an availability of a second field that is not currently presented, wherein the second field depicts the subject from a second location having a nonzero view distance from the projection; andupon receiving from the user an activation of the view indicator, present the second field instead of the panoramic field.
