Abstract

An image display and analysis system is disclosed. The image display and analysis system and method includes a system for reading an image having an object of interest. The image includes corresponding location data indicative of position and orientation of the image capturing device(s) used to capture the image. The system receives one or more selected points within the image on the object of interest, and calculates a measurement of the object of interest using pixel location, the position and orientation of the image capturing device(s), and a TGP vertical plane.

Claims

1. A computerized system for displaying, geolocating, and making measurements, comprising:

a computer system executing image display and analysis software reading;

an oblique image having corresponding location data indicative of a position and orientation of an image capturing device used to capture the oblique image, the oblique image depicting an object of interest; and

at least one data table storing ground plane data indicative of a plurality of first facets that closely approximates at least a portion of the terrain depicted within said oblique image, said at least one data table also comprising a TGP vertical plane data indicative of a second facet representing a mathematical model of the object of interest depicted within the oblique image,

wherein the image display and analysis software executed by the computer system displays at least a portion of the oblique image depicting the object of interest, receives one or more selected points within the oblique image on the object of interest and calculates a measurement of the object of interest using pixel location of the one or more selected points within the oblique image, the location data and the TGP vertical plane data.

2. The computerized system of claim 1, wherein the image display and analysis software is configured to utilize a single ray projection technique to calculate the measurement of the object of interest using the geo-location data and the TGP vertical plane data.

3. The computerized system of claim 1, wherein the image display and analysis software is configured to calculate a desired measurement within the oblique image utilizing the geo-location data and the ground plane data indicative of the plurality of first facets.

4. The computerized system of claim 1, wherein the TGP vertical plane data includes real-world three-dimensional location values representative of at least two points on the object of interest depicted in the oblique image and positioned at a distance farthest from a centerline of the object of interest.

5. The computerized system of claim 4, wherein the TGP vertical plane data includes at least one real-world three-dimensional location value representative of a three-dimensional location where the object of interest over lies the Earth and having an elevation value indicative of an elevation of the terrain underneath the object of interest.

6. The computerized system of claim 1, wherein the object of interest is a utility tower.

7. The computerized system of claim 1, wherein the image display and analysis software executed by the computer system displays at least a portion of the oblique image depicting the object of interest by providing a webpage that when rendered by a processor executing a Web browser displays at least a portion of the oblique image depicting the object of interest.

8. A method for taking measurements within a displayed oblique image, comprising:

receiving one or more signal indicative of first selection and pixel location of a first pixel within the displayed image of a first point on an object of interest depicted within the displayed oblique image;

retrieving from a data file, location data indicative of a position and orientation of an image capturing device used to capture the displayed image, and a TGP vertical plane approximating a center of mass of the object of interest; and

determining a real-world location of the first point utilizing the pixel location within the oblique image, the location data and the TGP vertical plane data.
