THREE DIMENSIONAL MEASUREMENT APPARATUS, CONTROL METHOD FOR THREE DIMENSIONAL MEASUREMENT APPARATUS, AND STORAGE MEDIUM |
摘要 |
A three dimensional measurement apparatus that measures a three-dimensional shape of a measurement subject based on an image obtained by capturing, by an image capturing unit, the measurement subject onto which a pattern is projected, the apparatus comprising: a compositing unit configured to composite a first image and a second image of the measurement subject respectively obtained under first imaging conditions and second imaging conditions that are different from the first imaging conditions, so that a relationship of an exposure amount produced by light incident on an image sensor of the image capturing unit and the magnitude of a luminance value corresponding to the exposure amount is maintained between the first image and the second image; and a measuring unit configured to measure the three-dimensional shape of the measurement subject based on the image composited by the compositing unit. |

1. A three dimensional measurement apparatus that measures a three-dimensional shape of a measurement subject on the basis of an image obtained by capturing, by an image capturing unit, the measurement subject onto which a pattern is projected, the apparatus comprising:
a compositing unit configured to composite a first image and a second image of the measurement subject respectively obtained under first imaging conditions and second imaging conditions that are different from the first imaging conditions, so that a relationship of an exposure amount produced by light incident on an image sensor of the image capturing unit and the magnitude of a luminance value corresponding to the exposure amount is maintained between the first image and the second image; and a measuring unit configured to measure the three-dimensional shape of the measurement subject on the basis of the image composited by the compositing unit. |
