Title:
IMAGE MEASURING METHOD AND RECORDING MEDIUM WITH RECORDED IMAGE MEASURING PROGRAM
Document Type and Number:
Japanese Patent JP3530978
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an image measuring method by a bundle adjusting method increasing the productivity of a measurement and to provide an image measuring program.
SOLUTION: A first image and a second image in which a reference target group and three or more discrimination targets are photographed in common by a movable imaging device from different positions and postures and in which noncommon discrimination targets are contained are photographed. The three-dimensional coordinates of the photographed positions and postures in both images and the three or more discrimination targets are calculated. The imaging device is moved. An n-th image (where n represents 3 or more), three or more coordinates-calculated discrimination targets inside an (n-1)th image and coordinates- calculated discrimination targets are photographed in common, and they are photographed in a position and a posture in which a discrimination target not common with the (n-1)th image is contained. A cycle in which the three-dimensional coordinates of the photographing position and the posture of the n-th image and the coordinates-uncalculated discrimination target are calculated is repeated. The three-dimensional coordinates of all the discrimination targets are calculated. By a handle adjusting operation based on the calculated value of the three-dimensional coordinates of all the discrimination targets, the measurement accuracy of the three-dimensional coordinates is increased.
