(1) with Laser Scanning Equipment face characteristic is taken record, make its feature become the cloud data file; Laser Scanning Equipment requires as far as possible fast, accurately face characteristic is recorded.A common photo can with the people on the face most features record, three photos can all be recorded all features of people's face (comprise from the ear to the ear at hair line with interior all three-dimensional features of people's face).After the end of taking pictures, utilize image processing software that the scan-data in the Laser Scanning Equipment is changed into complete cloud data, if with the photo more than two, then mate with the three-dimensional feature in the overlay region, it is complete faceform's cloud data that many Zhang San are tieed up the model cooperation.
(2) after obtaining faceform's cloud data, utilize some cloud software for editing that the faceform's cloud data that scans is carried out personalization and be trimmed to satisfactory people's face three-dimensional data model.The personalized finishing of described cloud data may further comprise the steps:
1, with in the faceform's cloud data input point cloud software for editing after the laser scanning, in software, sets up three-dimensional system of coordinate;
2, the thickness of faceform's cloud data is set, so that the editor of faceform's cloud data;
3, the position according to face's prosthese intercepts groups of people's face model point cloud data;
4, by faceform's cloud data of the personalized editor's intercepting of some cloud software for editing, make it become satisfactory faceform's cloud data.
(3) finish after people's face three-dimensional data model, carry out three-dimensional, the output model digital document is entered in the rapidform machine and shapes, and makes personalized face prosthese;
(4) face's prosthese of making is carried out the molded work of silica gel, then carry out the multiple mould of silica gel.
(5) the face's prosthese with the multiple mould of silica gel carries out computer aided measurement and analysis system, compares with former scan-data, meets required precision, can make personalized face prosthese.

Specific implementation method
Utilize our Laser Scanning Equipment and rapid forming equipment can produce fast, cheaply personalized face prosthese.This solves patient medical and takes costliness and the poor problem of medical effect so that hospital can produce the cheap face prosthese that meets patient's oneself requirement.
We are take the patient as laser scan object, utilize our Laser Scanning Equipment can obtain easily and fast the feature of patient face.Laser scanner technique is applied to the making explanation of personalized face prosthese:
1.. generate accurately people's face 3-D view (from an ear to another ear) with laser scanner technique.
2.. take pictures and can adopt 180 degree imaging systems, can adopt equipment to take, adopt the seat of rotation to change the person's of being taken shooting angle or fixing seat, carry out the shooting of multi-angle with mobile device.
3.. Laser Scanning Equipment can be realized the automatic or manual splicing.
4.. when taking people's face, require to take at short notice threedimensional model and the corresponding colored pinup picture of all angles as far as possible.Requirement can be caught people's minutia on the face.
1, with Laser Scanning Equipment face characteristic is taken record, make its feature become the cloud data file; Laser Scanning Equipment requires as far as possible fast, accurately face characteristic is recorded.A common photo can with the people on the face most features record, three photos can all be recorded all features of people's face (comprise from the ear to the ear at hair line with interior all three-dimensional features of people's face).After the end of taking pictures, utilize image processing software that the scan-data in the Laser Scanning Equipment is changed into complete cloud data, if with the photo more than two, then mate with the three-dimensional feature in the overlay region, it is complete faceform's cloud data that many Zhang San are tieed up the model cooperation.Described laser scanning may further comprise the steps:
1. the measured is just leaning against first white background wall seat, is with protective spectacles (protection eyes).Notice that the measured can not move in the scanning process.Keep original sitting posture as far as possible.
