1. A method of creating a three-dimensional model of a target object to be recognized by executing a process of restoring three-dimensional information of a contour line through three-dimensional measurement using a stereo camera with respect to an actual model of the target object to be recognized while arbitrarily changing a positional relationship between the actual model and the stereo camera every time, aligning the three-dimensional information restored by the measurement of a plurality of times, and integrating each piece of the three-dimensional information after the alignment;

  • wherein the steps of;

    extracting information in an overlapped relationship by matching a plurality of pieces of three-dimensional information to be integrated with each other and calculating a difference amount between contour patterns represented by the extracted information,determining an evaluation value representing accuracy of integrated information including the plurality of pieces of three-dimensional information based on the difference amount, andoutputting the determined evaluation value, are executed before integrating or after integrating the plurality of pieces of three-dimensional information.
