Methods and systems for detecting patch panel ports from an image having perspective distortion
First Claim
1. A method of estimating one or more dimensions of a patch panel, the method comprising:
- receiving an image of a patch panel, wherein the patch panel comprises a plurality of ports and one or more gaps;
extracting, by a computing device, a region of interest from the received image;
detecting, by the computing device, one or more possible port edges from the region of interest;
fitting the detected possible port edges to a cross-ratio constancy model to determine a port-to-gap-length ratio associated with the patch panel;
using the port-length-to-gap-length ratio to determine a location of one or more final port edges; and
determining a location of one or more final ports based on the location of the final port edges.

Abstract
A method of estimating one or more dimensions of a patch panel may include receiving an image of a patch panel that comprises a plurality of ports and one or more gaps, extracting, by a computing device, a region of interest from the received image, detecting, by the computing device, one or more possible port edges from the region of interest, fitting the detected possible port edges to a cross-ratio constancy model to determine a port-to-gap-length ratio associated with the patch panel, using the port-length-to-gap-length ratio to determine a location of one or more final port edges, and determining a location of one or more final ports based on the location of the final port edges.

10. A system for estimating one or more dimensions of a patch panel, the system comprising:
-
a computing device; and a computer-readable storage medium in communication with the computing device, wherein the computer-readable storage medium comprises one or more programming instructions that, when executed, cause the computing device to; receive an image of a patch panel, wherein the patch panel comprises a plurality of ports and one or more gaps, extract a region of interest from the received image, detect one or more possible port edges from the region of interest, fit the detected possible port edges to a cross-ratio constancy model to determine a port-to-gap-length ratio associated with the patch panel, use the port-length-to-gap-length ratio to determine a location of one or more final port edges, and determine a location of one or more final ports based on the location of the final port edges. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
