Abstract
In a measurement device, an imaging unit generates a first image and a second image. A subject distance detection unit detects a subject distance. A motion detection unit detects an amount of motion of the imaging unit. A measurement availability determination unit determines whether or not measurement is executable by comparing the amount of motion with an allowable threshold value according to the subject distance. A measurement processing unit executes a measurement process on the basis of the first image and the second image when the measurement availability determination unit determines that the measurement is executable.
Claims12
A measurement device, comprising:
- an image sensor configured to capture a first subject image via a first objective optical system at a first imaging timing, capture a second subject image via a second objective optical system at a second imaging timing different from the first imaging timing, generate a first image based on the first subject image, and generate a second image based on the second subject image, the second objective optical system being arranged to have parallax with respect to the first objective optical system;
- a motion sensor configured to detect an amount of motion of the image sensor;
- a processor configured to:
- detect a subject distance between the image sensor and the subject:
- determine whether or not measurement is executable by comparing the amount of motion with an allowable threshold value according to the subject distance;
- and
- execute a measurement process on the basis of the first image and the second image in response to a determination that the measurement is executable.
