Abstract

Abstract A system for generating digital image data bases automatically that is principally for use in visual systems of simulators and for use when a particular geographic area is not required. A data processing circuit generates high detail realistic images statistically under the control of a control data base. A conflict resolution data base retains data for identifying and for resolving geographic conflicts among features generated for a visual system.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 245 words
A system for generating data bases automatically that are ultimately used as visual scene data bases for a computer image generator wherein the final stored image is highly realistic in cultural geographical scene content, the system comprising: (a) data processing circuit means for generating digital signals that are storable as a data base for a digital image generator representing images having numerous edges forming polyhedra representing realistic visual cultural objects found in a visual geographical view of the earth's surface statistically in accordance with a predetermined data base generation program; (b) first means connected as an input to said data processing circuit means storing data identifying and describing prominent features to be included as a starting point in generating a data base in said data processing circuit means; (c) second means connected as an input to said data processing circuit means storing data describing the dominating cultural feature of a geographical area in the form of a hierarchy of features in which lower hierarchy features are for association with higher hierarchy features, in which predetermined attributes of each feature are in terms of an average and a standard deviation, said data influences the statistical generation of data bases by controlling which feature is associated geographically with which feature, the numbers of such features, and dimensions and angles associated with describing such features; and (d) third means to store data connected to output from said data processing circuit means for use by said digital image generator.
Claim 2
Independent Claim 245 words
A system for generating data bases automatically that are ultimately used as visual scene data bases for a computer image generator wherein the final stored image is highly realistic in cultural geographical scene content, the system comprising: (a) data processing circuit means for generating digital signals that are storable as a data base for a digital image generator representing images having numerous edges forming polyhedra representing realistic visual cultural objects found in a visual geographical view of the earth's surface statistically in accordance with a predetermined data base generation program; (b) first means connected as an input to said data processing circuit means storing data identifying and describing prominent features to be included as a starting point in generating a data base in said data processing circuit means; (c) second means connected as an input to said data processing circuit means storing data describing the dominating cultural feature of a geographical area in the form of a hierarchy of features in which lower hierarchy features are for association with higher hierarchy features, in which predetermined attributes of each feature are in terms of an average and a standard deviation, said data influences the statistical generation of data bases by controlling which feature is associated geographically with which feature, the numbers of such features, and dimensions and angles associated with describing such features; and (d) third means to store data connected to output from said data processing circuit means for use by said digital image generator.
Claim 3
Dependent Claim 37 words
A system for generating data bases automatically as claimed in claim 1 including fourth means to store data describing the identity of, and the resolution of, geographic conflicts among features generated by said data processing circuit means.
