System and method for precise location of a point of interest
First Claim
1. A method for locating a point of interest in a region, wherein an approximate model of the region is known, the method comprising:
- determining one or more characteristics of a region of interest within the region, wherein said region of interest includes the point of interest;
determining a continuous trajectory based on the one or more characteristics of the region of interest, wherein the continuous trajectory allows measurement of the region of interest;
measuring the region of interest at a plurality of points along the continuous trajectory to generate a sample data set;
performing a surface fit of the sample data set using the approximate model to generate a parameterized surface; and
calculating a location of the point of interest based on the parameterized surface.

Abstract
A scanning system and method for locating a point within a region. The method may: 1) determine or locate a region of interest in the region; 2) determine one or more characteristics of the region of interest within the region, wherein the region of interest includes the point of interest; 3) determine a continuous trajectory based on the one or more characteristics of the region of interest; 4) measure the region of interest at a plurality of points along the continuous trajectory to generate a sample data set; 5) perform a surface fit of the sample data set using the approximate model to generate a parameterized surface; and 6) calculate a location of the point of interest based on the parameterized surface. The method may include measuring the region at and/or near the calculated location to confirm the solution, and may also include generating output comprising the results.
