Title:
INFORMATION PROCESSING METHOD, INFORMATION PROCESSING SYSTEM, AND PROGRAM
Document Type and Number:
Japanese Patent JP2022030588
Kind Code:
A
Abstract:
To enable more precise association between a robot coordinate system and a sensor coordinate system.SOLUTION: An information processing method comprises the steps of: acquiring origin contact coordinate information, first contact coordinate information and second contact coordinate information on a prescribed plane of an object; acquiring three-dimensional model data from the object by means of a sensor; acquiring coordinate information of arbitrary 3 points on the plane of the object in the three-dimensional model data, and calculating a normal vector to the plane; acquiring coordinate information of each of arbitrary 3 points around a first hole and a second hole in the three-dimensional model data, and calculating first hole center coordinates and second hole center coordinates; calculating a linear vector connecting the first hole center coordinates and the second hole center coordinates; and associating the sensor coordinate system with the robot coordinate system with each other using the values of the linear vector, the normal vector, and a defined distance from the origin to a center of the first hole.SELECTED DRAWING: Figure 6
