Abstract
Abstract An arrangement for locating points on a surface, in which the surface is irradiated selectively and subdivided into a number of sections. The subdivided sections are made to overlap so that a region of one section overlaps the region of a neighboring section. Images of the irradiated sections are recorded, and then scanned for purposes of defining the location of predetermined points within overlapping regions of the subdivided sections. The location of the points within overlapping regions is dependent on a predetermined relationship of irradiated intensities of the points obtained during the scanning procedure.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
96 words
A method for locating points on a surface comprising the steps of: irradiating selectively and subdividing a surface into a number of sections; overlapping subdivided sections so that a region of one section overlaps the region of a neighboring section; recording images of the irradiated sections; and scanning said images to define the location of predetermined points within overlapping regions of said subdivided sections; the location of said points within overlapping regions being dependent on a predetermined relationship of irradiated intensities of said points obtained during said scanning and independent of background light and color effects.
Claim 2
Independent Claim
96 words
A method for locating points on a surface comprising the steps of: irradiating selectively and subdividing a surface into a number of sections; overlapping subdivided sections so that a region of one section overlaps the region of a neighboring section; recording images of the irradiated sections; and scanning said images to define the location of predetermined points within overlapping regions of said subdivided sections; the location of said points within overlapping regions being dependent on a predetermined relationship of irradiated intensities of said points obtained during said scanning and independent of background light and color effects.
Claim 3
Dependent Claim
126 words
A method as defined in claim 1 including the steps of: determining during scanning the irradiated intensity of said points when located in one subdivided section; determining during scanning the irradiated intensity of said points when located within an adjacent subdivided section overlapping the area of said one subdivided section on said surface; computing the value of said predetermined relationship of the irradiated intensities determined during scanning; generating a function of values of said relationship with respect to positions of said points; determining the irradiated intensities of a point to be located in said one and overlapping sections and computing the value of said relationship from said intensities; referring the last-mentioned computed value to said function and deriving the position of said point from said function.
Claim 4
Dependent Claim
19 words
A method as defined in claim 1 wherein the irradiated intensity varies over the area of the subdivided section.
Claim 5
Dependent Claim
27 words
A method as defined in claim 1 wherein the number of overlapping subdividing sections is dependent on the ratio of signal to noise of the irradiated sections.
Claim 6
Dependent Claim
70 words
A method as defined in claim 2 wherein said relationship corresponds to A/B, where A is the irradiated intensity of a point determined during scanning of said one section, and B is the irradiated intensity of the point determined during scanning of said adjacent section, said one section and said adjacent section being irradiated separately, said point being within an overlapping region of said one section and said adjacent section.
Claim 7
Dependent Claim
71 words
A method as defined in claim 2 wherein in said relationship corresponds to (A-B)/(A+B), where A is the irradiated intensity of a point determined during scanning of said one section, and B is the irradiated intensity of the point determined during scanning of said adjacent section, said one section and said adjacent section being irradiated separately, said point being within an overlapping region of said one section and said adjacent section.
Claim 8
Dependent Claim
36 words
A method as defined in claim 2 including the step of storing values of said predetermined relationship; and comparing thereafter the stored values with a value of said relationship computed from irradiated intensities determined during scanning.
Claim 9
Dependent Claim
101 words
An arrangement for locating points on a surface comprising means for irradiating selectively and subdividing a surface into a number of sections, said subdivided sections being overlapped so that a region of one section overlaps the region of a neighboring section; means for recording images of the irradiated sections; and means for scanning said images to define the location of predetermined points within overlapping regions of said subdivided sections; the location of said points within overlapping regions being dependent on a predetermined relationship of irradiated intensities of said points obtained during said scanning and independent of background light and color effects.
Claim 10
Dependent Claim
101 words
An arrangement for locating points on a surface comprising means for irradiating selectively and subdividing a surface into a number of sections, said subdivided sections being overlapped so that a region of one section overlaps the region of a neighboring section; means for recording images of the irradiated sections; and means for scanning said images to define the location of predetermined points within overlapping regions of said subdivided sections; the location of said points within overlapping regions being dependent on a predetermined relationship of irradiated intensities of said points obtained during said scanning and independent of background light and color effects.
Claim 11
Dependent Claim
135 words
An arrangement as defined in claim 8 including means for determining during scanning the irradiated intensity of said points when located in one subdivided section; means for determining during scanning the irradiated intensity of said points when located within an adjacent subdivided section overlapping the area of said one subdivided section on said surface; means for computing the value of said predetermined relationship of the irradiated intensities determined during scanning; means for generating a function of values of said relationship with respect to positions of said points; means for determining the irradiated intensities of a point to be located in said one and overlapping sections and computing the value of said relationship from said intensities; means for referring the last-mentioned computed value to said function and deriving the position of said point from said function.
Claim 12
Dependent Claim
19 words
An arrangement as defined in claim 8 wherein the irradiated intensity varies over the area of the subdivided section.
Claim 13
Dependent Claim
27 words
An arrangement as defined in claim 8 wherein the number of overlapping subdividing sections is dependent on the ratio of signal to noise of the irradiated sections.
Claim 14
Dependent Claim

An arrangement as defined in claim 9 wherein said relationship corresponds to A/B, where A is the irradiated intensity of a point determined during scanning of said one section, and B is the irradiated intensity of the point determined during scanning of said adjacent section, said one section and said adjacent section being irradiated separately, said point being within an overlapping region of said one section and said adjacent section.
Claim 15
Dependent Claim
70 words
An arrangement as defined in claim 9 wherein said relationship corresponds to (A-B)/(A+B), where A is the irradiated intensity of a point determined during scanning of said one section, and B is the irradiated intensity of the point determined during scanning of said adjacent section, said one section and said adjacent section being irradiated separately, said point being within an overlapping region of said one section and said adjacent section.
Claim 16
Dependent Claim
37 words
An arrangement as defined in claim 9 including means for storing values of said predetermined relationship; and means for comparing thereafter the stored values with a value of said relationship computed from irradiated intensities determined during scanning.
