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.
