Abstract
A conversion parameter calculation method includes: obtaining, from a first image capturing device, first image data obtained by the first image capturing device capturing an image of an object; obtaining, from a second image capturing device, second distance data indicating a distance to the object, and second image data obtained by the second image capturing device capturing an image of the object; obtaining displacement direction information indicating a direction of a displacement of the object in three dimensions; associating positions on the object in the first image data and the second image data; estimating a position of the first image capturing device; calculating first distance data indicating a distance from the first image capturing device to the object; and calculating a conversion parameter for converting a pixel displacement amount of the object into the actual displacement amount, using the first distance data and the displacement direction information.
