1. A method of estimating dimensions of a vehicle's exterior defects based on reference dimensions, comprising:
using at least one processor for:
analyzing at least one image captured by at least one image sensor deployed to depict at least one vehicle to identify at least one reference feature relating to the at least one vehicle;
obtaining a real-world size of the at least one reference feature;
computing a pixel to real-world size ratio for the at least one image sensor based on the real-world size of the at least one reference feature and a size in pixels of the at least one reference feature in the at least one image;
analyzing at least one image captured by the at least one image sensor to identify at least one defect in an exterior of the at least one vehicle;
computing a size in pixels of at least one dimension of the at least one defect; and
computing a real-world size of the at least one dimension based on the size in pixels of the at least one dimension and the pixel to real-world size ratio;
wherein the at least one reference feature comprises at least one physical reference feature of the at least one vehicle;
wherein the at least one physical reference comprises at least one wheel feature of at least one of the wheels of the at least one vehicle, the at least one wheel feature is a member of a group consisting of: a wheel rim size (diameter), and a tire aspect ratio (profile);
wherein the real-world size of the at least one wheel feature is determined according to tire dimensions marked on at least one tire of the at least one vehicle, the marked tire dimensions are identified by analyzing at least one image depicting at least one of the tires of the at least one vehicle.
