Title: Oblique photographic database generation
Inventor: PLUNK GERALD W
IPC: G06T15/20
Filed: 1991-07-22
Abstract: OBLIQUE PHOTOGRAPHIC DATABASE GENERATION ABSTRACT   Methods of generating a digital photographic database wherein oblique photo-graphs are taken at an angle which approximates a desired flight path. The photo-graphs may be taken at a single eye point using multiple cameras, each camera having increasing magnification, or may be taken with one camera at a plurality of different ranges along the flight path. Each photograph represents a resolution viewplane from which a computer synthesized image is generated to provide alternative eye point per-spectives. The methods of the present invention generate a corridor based multiple resolution photographic database wherein the amount of digital computer processing time is reduced by a factor of greater than one hundred as compared to conventional downlooking imagery conversion techniques that render oblique views. The methods of the present invention reduce the amount of digital image storage and provides a more realistic perspective view than rendering downlooking imagery to oblique views.

Filed: 1991-11-01
Abstract: A parcel processing system provides shipping documents required for a number of shipping carriers and/or classes of service. The system includes a keyboard, a scale, a memory, a printer and a processor. The processor receives carrier/service selection signals from the keyboard and transaction data from the keyboard and/or the scale. The processor determines on the basis of the carrier/service selection signal whether to rate or defer a parcel transaction. Data for a deferred transaction is stored in the memory. The foregoing steps are performed with respect to a number of transactions and a number of deferred transactions are combined into an aggregation. The processor receives a deferred rating signal from the keyboard and performs a rating operation with respect to the aggregation of deferred transactions. The printer prints a manifest reflecting the result of the rating operation.
