    • PROBLEM TO BE SOLVED: To obtain a human phantom which is suitable for training to learn doctor's skill, etc., in a field, such as diagnosis and surgery using an endoscope, where high skill is needed by using the materials having the mechano-dynamical characteristics approximating those of the human body. SOLUTION: Not only model materials are approximated in modulus of elasticity, surface colors, viscosity, etc., to a living body but also the structure compounded by using the plural materials for matching its characteristics more exactly to the mechanical characteristics of the human body than the internal structure is adopted, in order to enable a person who trains the manipulation of the endoscope to have the feeling of the taction sensation analogous with that of the actual living body. For example, the human body model 101 consists of a skeletal section 102 and a nasal cavity section 103. The skeletal section 102 is formed of silicone rubber colored to, for example, a mucous membrane color and is provided with hardness resembling the hardness of the actual human body. If a blank having an adequate X-ray absorptivity is used for the human body model 101, the image pickup by an X-ray CT is made possible. If, for example, barium sulfate is mixed into the nasal cavity section 103, the photographing of a cross sectional view becomes possible.

    • PROBLEM TO BE SOLVED: To measure the dynamic shape deformation of an object from many view points by plural shape sensors by obtaining the change of beam stripes without interference and surface pattern change in a measurement object. SOLUTION: The plural shape sensors 2 are arranged around a three-dimensional shape measurement object 1. The respective shape sensors are provided with a laser beam stripe projector 21 for projecting laser beam stripes by the lasers of different wavelengths, a laser beam stripe receiver 25 for receiving the beam stripes through a wavelength selection filter 26 for transmitting only the wavelength projected from the beam stripe projector 21 of the same shape sensor, and a pattern image receiver 27 for picking up the image of a pattern on the surface of the object 1 through a filter 28 for transmitting the wavelength other than the laser of the respective beam stripe projectors 21. The change of the beam stripes projected from the respective laser beam stripe projectors 21 to the object is image picked up in the respective laser beam stripe receivers 25, the surface pattern of the object 1 excluding the laser beam stripes is image picked up in the respective pattern image receivers 27, and the dynamic shape deformation and surface pattern change of the object 1 are measured from the image data.
