Coordinate calculating apparatus and coordinate calculating program
First Claim
1. A coordinate calculating apparatus for calculating two object position coordinate points from an image captured by an image capturing apparatus, the two object position coordinate points indicating positions of two predetermined objects whose images to be captured, the positions being on a plane corresponding to the captured image, the apparatus comprising:
- coordinate detecting means of detecting a position coordinate point of an area satisfying a predetermined condition in the captured image for each area;
reference setting means of setting a reference with respect to at least one of a direction connecting two position coordinate points in the captured image and a length between the two position coordinate points;
selection means of, when a plurality of position coordinate points are detected by the coordinate detecting means, with respect to combinations of two position coordinate points among the plurality of position coordinate points, comparing at least one of a direction connecting two position coordinate points in the combinations and a length between the two position coordinate points, with the reference, and selecting a combination of two position coordinate points in the combinations most close to the reference as the two object position coordinate points.

Abstract
A coordinate calculating apparatus detects a coordinate point (detected coordinate point) of an area satisfying a predetermined condition in a captured image for each area. When a plurality of position coordinate points have been detected, the coordinate calculating apparatus sets a reference (a previous vector or an assumed vector) concerning at least one of a direction indicating two position coordinate points in the captured image and a length between the two position coordinate points. The coordinate calculating apparatus selects a combination of two position coordinate points closest to the set reference, as two object position coordinate points, from combinations of two position coordinate points from the plurality of position coordinate points.

12. A computer readable storing medium storing a program which is executed by a computer of a coordinate calculating apparatus for calculating two object position coordinate points from an image captured by an image capturing apparatus, the two object position coordinate points indicating positions of two predetermined objects whose images to be captured, the positions being on a plane corresponding to the captured image, the program causes the computer to execute:
-
a reference setting step of setting a reference with respect to at least one of a direction connecting two position coordinate points in the captured image and a length between the two position coordinate points; and
a selection step of, with respect to combinations of two position coordinate points among position coordinate points of areas satisfying a predetermined condition in the captured image, comparing at least one of a direction connecting two position coordinate points in the combinations and a length between the two position coordinate points, with the reference, and selecting a combination of two position coordinate points in the combinations most close to the reference as the two object position coordinate points. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
