Patent ID: 6914623

Claim:
An image-processing measuring apparatus comprising: one or a plurality of image pick-up units for observation; one or a plurality of observation optical systems for forming an observation target on said image pick-up unit as an observed image from one or a plurality of view points; a processing unit for receiving a signal from said image pick-up unit, performing processing of the received signal, and generating a video signal; a display device for receiving and displaying the video signal from said processing unit and displaying said observation image; an estimating unit for estimating three-dimensional coordinates at an arbitrary point on said observed image based on an image signal in each view point obtained by said image pick-up unit, and for obtaining the estimation result and the reliability of the estimation result; a cut-off datum line input unit for inputting a cut-off datum line as a datum for setting a position of a cut-off plane of said observation target; a cross-section information generating unit for generating cross-section information of said observation target on said cut-off plane based on the estimation result of said estimating unit; a concave and convex datum line setting unit for estimating the reliability of a point on said cut-off datum line or on an extending line of said cut-off datum line based an the reliability of the estimation result of said estimating unit, extracting only a point whose reliability is high and setting both new ends, and setting a concave and convex datum line as a predetermined datum, based on both the set new ends; a concave and convex information generating unit for generating concave and convex information by treating said cross-section information to create said concave and convex information indicating a relative concave and convex state with respect to said concave and convex datum line; a concave and convex information processing unit for processing said concave and convex information to a visualized concave and convex index; and a concave and convex index display unit for displaying said concave and convex index.
