3D visualization of human organs is very important for human analysis. The 3D result is very useful for the surgery analysis, and it can also be used to produce human model by carve machine or 3D printer. There is a lot of method to got 3D data, such as 3D laser scan system, 3D phase measurement, shape from shading, shape from motion, shape from focus, shape from photometric, shape from stereo, etc. Laser scan system is the most commonly used method, but its measurement range relies much on the size of rotation or translation flat. Its measurement precision also relies much on the hardware precision. This paper will introduce a non-orbit, non-contact 3D measurement. The main idea is from shape from stereo technique. It will use two cameras to get the 3D data by the help of lighting system. The two cameras are placed in different view angle. After the high precision calibration system, the 3D absolute stereo coordinate can be got. The proposed 3D imaging method is proved that it is a high precision, low cost, and easy operation stereo matching method. It can be used to the visualization of human face, human head, human tooth, human body, etc. The visualization data can be used in the Face recognition or face surgery, tooth surgery, biologic Computer-aided instruction, human art etc. This method can help the doctor to analyze the surgery before the real surgery starts, thus to decrease the medical accident. The 3D data can also store more vivid information for human art and human memory. The 3D visualization method, the calibration system, the 3D data acquisition system, and the application of 3D visualization data will all be introduced in the paper.
