Abstract
Abstract The method of generating data for files containing information regarding three-dimensional surface configurations, involving selective compilation of area data through use of projected rays of differing orientation, recording of the radiation patterns produced by these rays on the surface, and correlation of records from overlapping fields of view to meld information from contiguous areas into a continuous data bank.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
171 words
A method for developing a data bank representative of the surface characteristics of a three-dimensional object, comprising defining a first projection field extending from a first location and including a part of said surface; irradiating portions of said part by projecting radiant energy from said first location into first predetermined segments of said first projection field; irradiating portions of said first part by projecting radiant energy from said first location into second predetermined segments of said first projection field, said second segments being of different orientation than that of said first segments; and making separate data files from at least two positions, containing records of such irradiated object portions in a succession corresponding to the irradiating succession; the field of view from each of said two positions including an overlapping area; whereby common points within said separate data files can be compared to coordinate said files with each other to effect merger thereof into a data bank representative of the surface characteristics of the field of view from each said position.
Claim 2
Independent Claim
171 words
A method for developing a data bank representative of the surface characteristics of a three-dimensional object, comprising defining a first projection field extending from a first location and including a part of said surface; irradiating portions of said part by projecting radiant energy from said first location into first predetermined segments of said first projection field; irradiating portions of said first part by projecting radiant energy from said first location into second predetermined segments of said first projection field, said second segments being of different orientation than that of said first segments; and making separate data files from at least two positions, containing records of such irradiated object portions in a succession corresponding to the irradiating succession; the field of view from each of said two positions including an overlapping area; whereby common points within said separate data files can be compared to coordinate said files with each other to effect merger thereof into a data bank representative of the surface characteristics of the field of view from each said position.
Claim 3
Dependent Claim
25 words
The method of developing a data bank as defined in claim 1, wherein said first and second predetermined segments are orthogonally disposed to one another.
Claim 4
Dependent Claim
56 words
The method of developing a data bank as defined in claim 1, wherein the irradiation of said first predetermined segments is effected by projecting radiant energy in a first group of substantially parallel rays, and the irradiation of said second predetermined segments is effected by projecting radiant energy in a second group of substantially parallel rays.
Claim 5
Dependent Claim
24 words
The method of developing a data bank as defined in claim 3, wherein the rays within each group are orthogonally disposed to one another.
Claim 6
Dependent Claim
67 words
The method of developing a data bank as defined in claim 1, wherein the field of view from the first position at which said data files are recorded is substantially coextensive with said first projection field, and the field of view from the second position at which said data files are recorded includes an adjacent area of said surface that is not irradiated from said first location.
Claim 7
Dependent Claim
157 words
The method of developing a data bank as defined in claim 1 comprising, defining a second projection field extending from a second location and including a second part of said surface, said second projection field also including an overlapping area with said first projection field; irradiating portions of said second part by projecting radiant energy from said second location into first predetermined segments of said second projection field; irradiating portions of said second part by projecting radiant energy from said second location into second predetermined segments of said second projection field, said second segments being of different orientation than that of said first segments; and making separate data files from one of said two positions and a third position containing records of irradiated object portions in a succession corresponding to the irradiating succession; the field of view from said third position including an overlapping area with the field of view from said one of said two positions.
Claim 8
Dependent Claim
25 words
The method of developing a data bank as defined in claim 6, wherein said first and second predetermined segments are orthogonally disposed to one another.
Claim 9
Dependent Claim
56 words
The method of developing a data bank as defined in claim 6, wherein the irradiation of said first predetermined segments is effected by projecting radiant energy in a first group of substantially parallel rays, and the irradiation of said second predetermined segments is effected by projecting radiant energy in a second group of substantially parallel rays.
Claim 10
Dependent Claim
27 words
The method of developing a data bank as defined in claim 8, wherein the rays of said first and second group are orthogonally disposed to one another.
Claim 11
Dependent Claim
70 words
The method of developing a data bank as defined in claim 6, wherein the field of view from said one of said two positions at which said data files are recorded is substantially coextensive with said second projection field, and the field of view from said third position at which said data files are recorded includes an adjacent area of said surface that is not irradiated from said second location.
Claim 12
Dependent Claim
76 words
The method of developing a data bank as defined in claim 6, wherein the data files from said two positions based on irradiation from said first location are made simultaneously at said two positions, thereafter the data files from said one of said two positions and said third position based on irradiation from said second location are made, and thereafter the data files from said third position based on irradiation from said second location are made.
