When an observer selects any image from this list, the thumbnail of the selected image is mapped onto the range-indicating image. With reference to this image, the observer can change the position, size and/or angle of the ROI-indicating frame by a mouse operation. In response to this operation, a magnified image of the sample within the new ROI is acquired.

  • Patent number: 9693048
    Abstract: A process and apparatus provide high speed multicomponent imagery from high frame rate binary spatial light modulators. The process and apparatus decompose an image frame into a plurality of subframes such that each subframe in the plurality of subframes corresponds to an image component of the image frame. The process and apparatus sequentially illuminate, with a spatially addressable backlight, each of the subframes displayed on a spatial light modulator segment through a lenslet array and at least one optical component onto a diffuser. Further, a process and apparatus provide high speed projection with multiple projectors. The process and apparatus decompose an image frame into a plurality of image components. Further, the process and apparatus associate each of the plurality of image components with each of a plurality of associated projectors. The process and apparatus concurrently projects the plurality of image components from the plurality of associated projectors.

  • Patent number: 9571796
    Abstract: A solution including a noncontact electronic measurement device is provided. The measurement device includes one or more imaging devices configured to acquire image data of a surface of an object located in a measurement region relative to the measurement device and one or more projected pattern generators configured to generate divergent pattern(s) of structured light, which impact the surface of the object within a field of view of the imaging device when the object is located in the measurement region. Using image data acquired by the imaging device(s), a computer system can measure a set of attributes of the surface of the object and/or automatically determine whether the measurement device is within the measurement region. An embodiment is configured to be held by a human user during operation.

  • Patent number: 9557161
    Abstract: Method and apparatus for measuring sizes of objects by using photograph. Method includes taking photograph by using camera; recognizing reference scale in photograph and measuring size of reference scale; measuring vertical direction angle and horizontal direction angle between the camera and the objects by using image properties of the recognized reference scale; recognizing the objects in the photograph and measuring vertical sizes and horizontal sizes of the objects; and acquiring actual vertical sizes and actual horizontal sizes of the objects by compensating the measured vertical size and the measured horizontal size of the objects based on the size of the reference scale, the actual size of the reference scale, and the vertical and horizontal direction angles. Therefore, heights and widths of objects distributed throughout a wide area may be precisely measured regardless of positions of the objects by using a reference scale for comparatively measuring sizes of the objects.

  • Patent number: 9138790
    Abstract: A method for measuring flatness of a sheet material in which a light and dark pattern composed by a light portion and a dark portion is projected onto a surface of the sheet material running in a longitudinal direction, a pattern image is acquired by photographing the light and dark pattern by an image pickup device having an image pickup visual field larger than a width of the sheet material, and the flatness of the sheet material is measured by analyzing the acquired pattern image. A staggered pattern is used for the projecting step and for light to be specularly reflected for receipt by the image pickup device. Calculating the flatness also includes steps of setting a shape measurement line, averaging picture element concentrations, calculating a distribution of the concentrations, and calculating the flatness based on surface shape using the distribution.

  • Publication number: 20150138348
    Abstract: A tiltmeter-integrated two element relative alignment optical monitor relative alignment and contact sensing and can provide precise information regarding the nature of physical contact experienced by the objects being monitored. A computer monitor can display the information in real time, in an intuitive manner. This system can provide all the information with good resolution in a low-cost, easily installable package for both high energy physics applications and industrial uses. The system includes a projector unit mounted on one component, with a diffuse light source, a coded mask, and a lens, the projector aligned with a camera to receive the focused image. Shifts in the image of the mask indicate relative motion between the camera and the projector unit. A tiltmeter is affixed to either the camera or projector, to distinguish between image shifts due to translational movement and image shifts due to rotation or tilting.
