Abstract:
1. A method of non-contacting morphometry of three-dimensional surface of an object having a plurality of measuring video heads disposed facing the object to be measured and a controlling unit for controlling the measuring time period for each of m measuring video heads and for processing and storing the measured data, comprising the steps of: placing the object to be measured so that one axis thereof lies along and with an imaginary central axis; placing the object to be measured so that the measuring heads are arranged on each of n (n≧1) planes intersecting the imaginary central axis where the optical axis of each measuring head faces the imaginary central axis and each annular slice of the surface of the object is covered by the sight fields of the m (m≧3) measuring heads; operating simultaneously one group of a plurality of measuring video heads, the sight field of each of which does not substantially overlap with the sight field of the others in the group, and thereafter, operating another group of a plurality of measuring video heads, the sight field of each of which does not substantially overlap with the sight field of the others in the group; and processing the n×m sets of data obtained in the foregoing steps and thereby to obtain three-dimensional data.
