  • Publication number: 20180101963
    Abstract: To provide a shape measuring device capable of quickly and accurately acquiring a measurement value of a desired part of a measuring object. A specifying section 32 sets, on the basis of a relative positional relation between the first region in the measurement luminance image and a second region in the reference luminance image, a measurement target region corresponding to the reference target region in the measurement height image. A calculating section 33 calculates, on the basis of measurement height image data, a measurement value concerning height of the measuring object in the measurement target region.

  • Patent number: 8854398
    Abstract: There are provided a waveform observing apparatus and waveform observing system that solve a problem of displacement of a handwritten comment which occurs with enlargement/reduction in display in such a manner that, when a determination is NO in a process step, namely when a current compression ratio differs from a compression ratio at the time of writing a handwritten comment in displaying the handwritten comment to such a degree as to cause occurrence of non-allowable displacement, a process proceeds to a next process step, and a simple indication indicating the presence of the handwritten comment is displayed in a position associated with a portion of a waveform corresponding to a measured data number.

  • Patent number: 8332171
    Abstract: There is provided a waveform observing apparatus, which facilitates management of compressed data and measured data that were created for a reduced display, reduces a calculating amount in making the reduced display, and displays a boundary between stoppage and start of collection of measured data in a visually observable manner, in such a manner that, when a compression ratio is set to the number of pieces of data per display dot, a plurality of compressed data of a compressed-data file for display with a smaller compression ratio than the above used to calculate compressed data, to make a reduced display at the compression ratio after the setting change, final compressed data is created based upon measured data of a fraction at the time of stoppage of sampling, top compressed data is created based upon measured data of a fraction immediately after resuming of the sampling at the time of the resuming.
