Provided is a
system for providing an online fitting glasses manufacturing service using a 3D
head shape, comprising: a user terminal that photographs a face and a
head shape, selects a glasses frame, and uploads an
optometry report; and a manufacturing service providing
server including a modeling unit for generating a 3D
head shape on the basis of the face and the head shape photographed by the user terminal, a selection unit for selecting a sample head shape most similar to the 3D head shape from among pre-manufactured sample head shapes, an output unit that compares the selected sample head shape with the 3D head shape and outputs parts having different sizes to a store terminal, and a fitting guide unit that outputs a pre-stored glasses frame fitting process to the store terminal if the size of the part of the sample head shape has been adjusted like the 3D head shape.
