DIMENSION ESTIMATION APPARATUS, DIMENSION ESTIMATION PROGRAM AND DIMENSION ESTIMATION METHOD

摘要

PROBLEM TO BE SOLVED: To accurately measure dimensions of a subject by using one photographic image 101 obtained by imaging the subject from an oblique direction.;SOLUTION: A posture reference axis setting unit 120 generates two-dimensional posture reference axis data 129 expressing a posture of a subject captured in the photographic image 101. A reference axis vector estimation unit 140 calculates a three-dimensional reference axis vector 149 expressing the posture of the subject on the basis of the posture reference axis data 129 and a photographic parameter 139. A reference setting unit 150 calculates a reference segment vector 159a expressing a reference segment of the subject by using the reference axis vector 149. A dimension estimation unit 160 calculates a measurement segment vector expressing a measurement segment of the subject by using the reference axis vector 149. The dimension estimation unit 160 calculates a length of the measurement segment by using a known reference segment length 159a, the reference segment vector 159a and the measurement segment vector.;COPYRIGHT: (C)2014,JPO&INPIT
