1. A system for surgical mesh analysis, the system comprising:
a display screen;
a processor; and
a memory having instructions stored thereon, which when executed by the processor, cause the system to:
access an image of a surgical site, the image including the surgical mesh, wherein the surgical mesh includes a grid of cells;
detect a first location on the surgical mesh in the image;
detect a second location on the surgical mesh in the image;
determine a distance between the first location and the second location along the surgical mesh in the image;
display, on the display screen, the determined distance, and
wherein when executing the instructions to determine the distance between the first location and the second location, the instructions further cause the system to at least one of:
determine a number of cells of the grid of cells along a shortest distance between the first location and the second location;
perform a Euclidean reconstruction based on analyzing the surgical mesh as a 3D structure composed of polygons, each polygon corresponding to a unique cell of the grid of cells; or
perform a geodesic reconstruction based on analyzing the surgical mesh by forming a topographic map of the surgical mesh and calculating distances between the first desired location and the second desired location based thereon.
