摘要： A camera input expansion unit includes a camera-setting-information storage, a camera expansion processor, an image-recorder, and an image capture interface. The camera-setting-information storage stores setting information on the camera including the conditions of the image capture trigger. The camera expansion processor generates an ON/OFF signal for defining the image capture trigger based on the setting information of the camera. Based on the ON/OFF signal as the image capture trigger, the camera expansion processor acquires the image data which is generated by the camera. The image-recorder records the image data acquired by the camera expansion processor. The image capture interface is provided between the camera expansion processor and the camera. The image capture interface has an image-capture-trigger line propagating the ON/OFF signal to the camera and an image communication line propagating the image data generated by the camera to the camera expansion processor.

摘要： To provide an optical-scanning-height measuring device capable of efficiently measuring a shape of a desired portion of a measurement object. Designation of a measurement point on an image of a measurement object S is received. Light emitted from a light emitting section 231 is deflected by the deflecting section and irradiated on the measurement object S. The deflecting section is controlled to irradiate the light on a portion of the measurement object S corresponding to the measurement point. A deflecting direction of the deflecting section or an irradiation position of the light deflected by the deflecting section is detected. Height of the portion of the measurement object S corresponding to the measurement point is calculated on the basis of the deflecting direction of the deflecting section or the irradiation position of the light deflected by the deflecting section and the light reception signal output by the light receiving section.

摘要： To enable scanning using measurement light with a small-sized displacement measuring apparatus. The displacement measuring apparatus includes a MEMS mirror for scanning using measurement light that is output from a light projection lens. The light projection lens has a focus position, at which the measurement light is condensed, at the MEMS mirror or in the vicinity of the MEMS mirror on an optical axis of the measurement light. The measurement light that is reflected at the MEMS mirror spreads in a strip-shaped manner as the measurement light comes close to a measurement region.

摘要： To enable short-time measurement of a displacement at a predetermined position of a measurement object even when the position or the posture of the measurement object is changed. During operation of a displacement measuring apparatus, the position and the posture of a measurement object are determined by using position correction information, and a measurement position is corrected. The corrected measurement position is irradiated with measurement light. The measurement light that is emitted to and is reflected back from the measurement position is received by a light receiver. The light receiver outputs a received-light quantity distribution for displacement measurement, and a displacement at the measurement position is measured on the basis of the received-light quantity distribution.

摘要： Optical axes of lens units of measurement heads are adjusted so as to be parallel to each other. The lens unit includes a diffraction lens. When adjusting the optical axis, in a state where the measurement heads face each other with a reference member interposed therebetween, light having a plurality of wavelengths are emitted from the measurement heads to one surface and the other surface of the reference member, respectively. Intensities of primary light having one wavelength, which are reflected by one surface and the other surface of the reference member respectively, and incident on the measurement heads through each of a path of a multi-order light having other wavelengths are displayed on a main display unit as information indicating a degree of orthogonality of the optical axes of the measurement heads with respect to the one surface and the other surface of the reference member.

摘要： To enable effectively narrowing down features to be generated, thereby generating effective features at a high speed, in obtaining the features from a large volume of data. A fixed rule and an additional rule are stored in advance. The fixed rule specifies a rule of a calculation operation for generating a new feature. The additional rule specifies whether to perform a calculation operation for generating the new feature on a basis of meta-information, not depending on whether the fixed rule is applicable. An objective variable is predicted from plurality of features on the basis of the fixed rule and the additional rule.

摘要： There is provided an optical displacement meter capable of accurately measuring a profile of a measurement object even when multiple reflections are caused. At the time of setting, reference data indicating a reference profile of a measurement object is registered by a registration unit 1, and a mask region is set to the reference data by a setting unit 2. At the time of measurement, reflected light from the measurement object is received by a light receiving unit 121, and a peak in an output light receiving amount distribution is detected by a peak detection unit 3. Temporary profile data of the measurement object is generated by a profile generation unit 4 based on a position of the detected peak. A position of the mask region for the temporary profile is corrected by a correction unit 5.
