The Application Of Face Three-Dimensional Measuring System In Medical Measurement

The application of 3-D shape measurement is more and more important in domain of modern industry, medical science, dress designing and video technology, etc. Since the optical three-dimension measurement is of high precision, non-touching and easy automation, it becomes a hot spot. The field includes theface analysis which has been thought highly. Photographing human face as two-dimensional picture is common at present in and out overseas, which is not comprehensive and can be restricted easily. The more mature analysis way to get three-dimensional face appearance is to survey at the bone tissue aspect based on x-ray technology, which has some influence to the human body. The survey system for soft tissue of face and iatrology is still under the developmentThis paper attempted to get 3D face data by fast phase-shift based on the staticoptical three-dimension measurement, obtain the more ideal experimental result andlist the detail theoretical and realism analysis.The process is as follows: adjusted the camera after analyzing the projection principle of fast phase, then established an effective fast projection phase-shift measurement. Foreclosed the data after obtaining the measure result and found the three-dimensional face model to analyze face characteristics, with constructing the three-dimensional graph by OpenGL and finding a face changing design by editing the graph, We developed a set of complete CAD computer three-imensional simulation medicine measurement system based on above process and reversion project principle. This system integrates optical measurement, data processing, the construction of data design, the three dimensional graphical display and the man-machine operated alternately, tidies up the plan design, three dimensional person face database creation and so on a series of functions module.The strong function will be able to bring convenience for doctors and their patients, bring the new survey method for the face orthopedic surgery and promote surgery filed to a fast development, provide a new fast-gain method and found face...
