Abstract
The present invention provides a method and apparatus for non-contacting morphomtry of three-dimensional surface of an object such as a human body in a shorter time period and with higher precision, wherein the present non-contacting morphometry of three-dimensional surface of an object involves a plurality of measuring video heads, Ai, Bi, Ci and Di and a controlling unit for controlling the measuring time of the measuring heads and for processing and storing the obtained data from the measurements. The present method comprises 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 other in the group, and thereafter, operat…
