  • Patent number: 11941852
    Abstract: A three-dimensional measurement device includes an image data receiving unit, a camera position selecting unit, a stereoscopic image selecting unit, and a camera position calculator. The image data receiving unit receives data of multiple photographic images. The photographic images are obtained by photographing a measurement target object and a random dot pattern from multiple surrounding viewpoints by use of a camera. The camera position selecting unit selects camera positions from among multiple positions of the camera. The stereoscopic image selecting unit selects the photographic images as stereoscopic images from among the photographic images that are taken from the camera positions selected by the camera position selecting unit. The camera position calculator calculates the camera position from which the stereoscopic images are taken. The selection of the camera positions is performed multiple times in such a manner that at least one different camera position is selected each time.

  • Patent number: 10538429
    Abstract: In a calculator in a MEMS manufacturing system, a stage control unit inclines a stage based on a stage angle 1 setting a stage inclination angle and a stage angle 2 of the inclination angle different from the stage angle 1. A stage-angle calculation unit calculates the stage inclination angles from first and second images acquired by a SEM apparatus when the stage control unit sets the stage at the stage angles 1 and 2. A 3D-data creation unit creates three-dimensional device data from a third image that is a device image acquired when the stage is set at the stage angle 1 and a fourth image that is a device image acquired when the stage is set at the stage angle 2. When the three-dimensional device data is created, a correction value calculated from the stage angles 1 and 2 and the first and second images is used.
