The embodiment of the invention provides a quantitative evaluation method of the face shape element map comprehensive quality. The method comprises the steps of using a calculation method of cosine similarity to calculate the similarity of selected, simplified, dimension-reduced and merged operator conditions according to a comprehensive front face shape element map and a comprehensive rear face shape element map provided by a user, and dividing a comprehensive quality evaluation result of a comprehensive operator by an operator element sum so that a quantitative evaluation result of the face shape element map comprehensive quality can be obtained. In all the computing progresses, the data is substituted into a formula to be calculated, then a computer can be utilized to directly conduct quantitative calculation, the evaluation result is automatically obtained, the purpose of automating a face shape element map comprehensive progress is achieved, and the user can be assisted in choosing an optimal comprehensive scheme.
