This image measurement device calculates a parallax value from image data of an image having parallax, uses the parallax value to acquire three-dimensional positional information when capturing the image data, and calculates a three-dimensional plane from an area on the image, said area occupying the same plane as a specified measurement area. Length is calculated by acquiring, from the calculated three-dimensional plane, a three-dimensional position of the measurement region. As a result, captured images having parallax can be used to measure the length of arbitrary places, even with respect to areas for which parallax values are difficult to obtain. |
