Technical field
The present invention relates to a kind of assessment system more particularly to a kind of facial area postoperative effect assessment systems.
Background technique
Currently, reaching desired lift face postoperative effect is the sole purpose for doing cosmetic surgery.But it is described since language lacks
The accuracy of image can not arrange effect after lift face in contract in the preoperative.So being that can not know postoperative effect before surgery
, cause preoperative lift face postoperative effect to be assessed vacant always.Which increase the uncertainty of lift face postoperative effect and doctor and
The probability of dispute occurs for operation receiveing person.Some doctors modify with graphics software is intended to operation receiveing person's appearance, to simulate postoperative effect,
But authenticity is poor, and the analysis of no quantization data is compared, and cannot function as the postoperative effect of preoperative agreement, only do referring generally to.
Currently, what effect cosmetic surgery, which reaches, is determined by doctor.Doctor is according to oneself experience, in conjunction with universal
Aesthetic conceptions, and the communication with patient, are operated.Patient is to final lift face postoperative effect, without effective right to speak.
It is therefore desirable to design a kind of facial area postoperative effect assessment system, to overcome the above problem.

With volume automatic measurement system.
Further, the facial area postoperative effect assessment system includes shaping effect expert evaluation system
Further, in S3, after forming postoperative face shaping template, plastic operation is carried out, face after shaping is obtained, it is right
3-D scanning is carried out after patient face and shaping, obtains three-dimensional point cloud and image data.
Further, face's eye, nose, lip, chin characteristic point are extracted using partial descriptions submethod in S2.
Further, the analysis of preoperative, post-procedure data compare compare including characteristic point position, symmetry index compares and refers to ratio
Number compares.
The invention has the following advantages:
Facial area postoperative effect assessment system provided by the invention by acquiring preoperative and postoperative all data, then into
Row analysis is compared, and can effectively be judged the quality of facial area postoperative effect, and combine the rational analysis of shaping expert system, can be given
A kind of lift face postoperative effect the most intuitive of patient determines conclusion.
