    • A three-dimensional imaging unit includes a plurality of image pickup devices that image an image and a rotation drive device which rotates the image pickup devices and adjusts optical axes such that reflections of an object to be measured in a space to be measured have a predetermined amount of overlap. An association calculating unit calculates position association information of pixels when a required measurement point is mapped onto a plurality of images. A three-dimensional shape calculating unit calculates a three-dimensional shape of the object to be measured using the position association information and rotational information of the rotation drive device. A three-dimensional shape estimation calculating unit estimates, from the three-dimensional shape, a three-dimensional shape of a region of the object to be measured where the three-dimensional shape is not obtained. A three-dimensional measurement coordinates calculating unit calculates, from an estimation result, three-dimensional coordinates of two distance measurement points designated on the object to be measured. A distance calculating unit calculates a distance between the two points using the three-dimensional coordinates.
    • 三维成像单元包括对图像进行成像的多个图像拾取装置和旋转图像拾取装置的旋转驱动装置,并且调整光轴,使得待测量空间中待测量物体的反射具有预定的 重叠量。 关联计算单元,当所需测量点映射到多个图像上时,计算像素的位置关联信息。 三维形状计算单元使用位置关联信息和旋转驱动装置的旋转信息来计算被测量物体的三维形状。 三维形状估计计算单元从三维形状估计未获得三维形状的待测量对象的区域的三维形状。 三维测量坐标计算单元从估计结果计算在被测量物体上指定的两个距离测量点的三维坐标。 距离计算单元使用三维坐标来计算两点之间的距离。
