<P>PROBLEM TO BE SOLVED: To provide a technology for accurately associating the measurement segment in a measuring object with an edge of the measuring object on a picked-up image and more accurately measuring the position attitude of an imaging device using the association relation. <P>SOLUTION: A measurement segment projection section 400 arranges a three-dimensional model in the position attitude of an actual object 199, and then projects the three-dimensional model on the picked-up image. Around a side constituting the three-dimensional model projected on the picked-up image, a side of the actual object 199 on the picked-up image is retrieved. Using the association relation, which is determined based on the retrieval result, between each side constituting the three-dimensional model projected on the picked-up image and each side constituting the actual object 199 positioned on the picked-up image, the position attitude relation between the actual object 199 and the imaging device 50 is calculated. When the retrieval is performed around an attention side, the range of the retrieval is set in response to the positional relation between the attention side and each side constituting the three-dimensional model projected on the picked-up image. <P>COPYRIGHT: (C)2009,JPO&INPIT |
