发明名称 Method and apparatus for processing image of patch panel
摘要 A method for processing an image of a patch panel includes: a) receiving an initial image; b) determining multiple ports of the patch panel are aligned in a desired orientation in the initial image; c) processing the initial image to identify edge lines perpendicular to the desired orientation; d) processing the edge lines to identify a port hypothesis that includes an estimated port gap between the multiple ports along the desired orientation and an estimated port size for the multiple ports along the desired orientation; e) processing the port hypothesis to determine an estimated port quantity for the multiple ports; and f) processing the port hypothesis to identify an estimation error between expected and detected edge line positions in relation to a reference axis perpendicular to the edge lines. An apparatus associated therewith includes an input/output and pre-processing modules and detection, hypothesis, estimating, and scoring processors.

主权项 1. A method for processing an image of a patch panel, comprising: a) receiving an initial image of a patch panel from an image source device at an image processor; b) determining multiple ports of the patch panel are aligned within a predetermined threshold of a desired orientation in the initial image; c) processing the initial image using a detection algorithm to identify edge lines that are perpendicular to the desired orientation; d) processing the edge lines in relation to the initial image using a hypothesis algorithm to identify a first port hypothesis that includes an estimated port gap between the multiple ports along the desired orientation and an estimated port size for the multiple ports along the desired orientation, the estimated port gap based at least in part on a distance between a first pair of adjacent edge lines, the estimated port size based at least in part on a distance between the first edge line pair and another edge line adjacent to the first edge line pair; e) processing the first port hypothesis in relation to the initial image using an estimating algorithm to determine an estimated port quantity for the multiple ports based at least in part on the estimated port gap and the estimated port size; and f) processing the first port hypothesis in relation to the initial image using a scoring algorithm to identify an estimation error between expected and detected edge line positions in relation to a reference axis perpendicular to the edge lines based at least in part on the estimated port quantity, estimated port gap, and estimated port size.
