Claims (7)

Three imaging unit even without least selects the two images from the image captured by each by reference to the two images selected, the position calculating position information indicating a position on the three-dimensional Target point an information calculator <br/>,
The measurement apparatus, wherein the two images selected by the position information calculation unit differ depending on a distance in real space from the imaging unit to the target point or an edge direction of a subject at the target point . The position information calculation unit selects two images from among images captured by the at least three imaging units according to a distance in real space from the imaging unit to the target point.
The measuring apparatus according to claim 1. The position information calculator is one of the image by the imaging unit has captured among the at least three imaging unit is selected as a reference picture, out of the image pickup unit other than the imaging unit of those said reference image obtained by imaging, either Select the image captured by the imaging unit as the reference image,
The positional information calculation unit captures the reference image from the imaging unit that captured the reference image as the distance in real space from the imaging unit that captured the reference image to the subject imaged at the position of the target point increases. The measurement apparatus according to claim 2, wherein the reference image is selected so that the distance to the image capturing unit becomes longer . The position information calculation unit selects two images from among images captured by the at least three imaging units, respectively, according to the edge direction of the subject at the target point.
The measuring apparatus according to any one of claims 1 to 3, wherein The position information calculation unit selects an image captured by at least two imaging units arranged along a direction different from the edge direction;
The measuring apparatus according to claim 4. Three imaging unit even without least selects two images from the image captured by each by reference to the two selected images, and calculates position information indicating a position on the three-dimensional of the target point Including
The measurement method characterized in that the two selected images differ depending on a distance in real space from the imaging unit to the target point or an edge direction of a subject at the target point . A measurement program for causing a computer to function as the measurement apparatus according to claim 1, wherein the measurement program is for causing the computer to function as the position information calculation unit.
