  • Patent number: 10636158
    Abstract: A mobile computing device used for measuring the height of an object, such as a human user, may be positioned on a reference surface, such as the ground plane. The reference surface is detected and a position guide is generated in an augmented reality (AR) plane on a display of the mobile computing device. The AR plane enables the object being measured to be positioned at a measurement position located at a predefined distance along the reference surface from the mobile computing device. The top and bottom of the object are detected in an image taken by the mobile computing device. The height of the object is measured based on the predefined distance and a distance between the top and bottom of the object in the image. The height of the object can also be measured with assistance from software development kits (SDKs) included in the mobile computing device.

  • Patent number: 10360315
    Abstract: The object is to enable easy acquisition of an element that is not design data. The technique is characterized in that when generating construction field management information used to manage a construction field, a construction field management device acquires measurement data that is three-dimensional shape data measured by a measurement device, and compares design data created by a designer with the acquired measurement data, thus extracting non-design data that is not the design data, from the measurement data. Also, as the non-design data, data of a scaffolding/tool and a component of the design data in a temporarily placed state are extracted, and the status of these is analyzed and displayed on a display unit.

  • Publication number: 20150051862
    Abstract: Methods are described for measuring series of nominally identical production workpieces on a dimensional measuring apparatus such as a coordinate measuring machine. One master workpiece of the series is calibrated, to provide correction values which are used to build an error map of the measuring apparatus. This map is used to correct measurements not only of subsequent nominally identical workpieces of the same series, but also of multiple different subsequent series of different workpieces. Each subsequent series also has a master workpiece which is calibrated and used to further build the error map. As this process is repeated over time, the error map becomes more and more densely populated. In due course, it becomes possible to dispense with the use of a calibrated master workpiece, because measurements can be corrected using error values which already exist in the error map.

    Abstract: A calibrating method of calibrating a measured distance of a measured object measured by a distance-measuring device according to an ambient temperature includes providing a temperature sensor for measuring the ambient temperature of the distance-measuring device, calculating a calibrated imaging location of the measured object according to the ambient temperature and an imaging location of the measured object, and calibrating the measured distance according to the calibrated imaging location. In this way, when the distance-measuring device measures the measured object, the error due to the variation of the ambient temperature is avoided according to the calibrating method.

  • Patent number: 8712720
    Abstract: A tire measurement system includes a computer with various memory/media elements for storing raw and transformed tire measurement data (e.g., a data set of measured radial or lateral run-out values) as well as software in the form of computer-executable instructions, which are executed by a processor to filter selected run-out values within the obtained data set that spike above adjacent measurements, identify selected ones of the filtered run-out values that lie on a convex hull surrounding the entire set of values, and perform interpolation of the identified selected ones of the run-out values that lie on the convex hull to obtain a final data set of filtered run-out measurements. Similar steps can be performed on an inverted data set to better detect sidewall deformation features such as sidewall depressions.

  • Patent number: 8712713
    Abstract: A method and apparatus for combining pressure information from pressure sensors, motion information from dead reckoning or other motion sensors, such as accelerometers, gyroscopes, and geomagnetic sensors, and temperature information from temperature sensors, to separate a change in altitude from a change in environmental pressure or temperature. A change in measured pressure without any motion or change in temperature must be a weather-related barometric pressure change. If there is an associated temperature change, but no motion, and the rate of change is too fast for a normal weather change, the measured change represents a change in sensitivity of the pressure sensor with temperature, and the sensor calibration can be adjusted. A rapid change in pressure, associated with horizontal motion, but no measurable vertical motion represents a movement into a different pressure environment. Only changes in pressure that are associated with measurable vertical motion are true changes in altitude.

  • Patent number: 8673641
    Abstract: A measuring method of chromium-free coating film thickness on surface of strip steel comprising selecting two water-soluble chemical substances containing elements P, Ca, Ti, Ba or Sr and not reacting with a chromium-free coating liquid; adding the chemical substances into the chromium-free coating liquid and agitating them to be homogeneous, thereafter, fabricating a reference sample of coating film; using a ray emitted by an off-line film thickness instrument to excite the two water-soluble chemical substances so as to obtain characteristic spectrums to obtain a correction function expression between the measured film thickness and the thickness correction value by fitting; adding the water-soluble chemical substance which has a weak characteristic spectrum into a chromium-free coating liquid, and using the expression to obtain the actual coating film thickness. The method is capable to monitor film thickness with no adverse effect on adhesiveness and corrosion-proof of the coating film.

  • Publication number: 20140074419
    Abstract: A method includes irradiating a surface of a sample, which is made-up of multiple types of materials, with a beam of primary electrons. Emitted electrons emitted from the irradiated sample are detected using multiple detectors that are positioned at respective different positions relative to the sample, so as to produce respective detector outputs. Calibration factors are computed to compensate for variations in emitted electron yield among the types of the materials, by identifying, for each material type, one or more horizontal regions on the surface that are made-up of the material type, and computing a calibration factor for the material type based on at least one of the detector outputs at the identified horizontal regions. The calibration factors are applied to the detector outputs. A three-dimensional topographical model of the surface is calculated based on the detector outputs to which the calibration factors are applied.

  • Publication number: 20130289918
    Abstract: A method includes measuring a caliper of a sheet of material using a caliper sensor having first and second sensor modules. The method also includes adjusting the caliper measurement based on a transverse displacement between a first sensor component in the first sensor module and a second sensor component in the second sensor module to generate a corrected caliper measurement. Adjusting the caliper measurement can include applying a corrector function that adjusts the caliper measurement based on the measured transverse displacement. The corrector function can be identified by repeatedly creating misalignment between the first and second sensor components, measuring a known distance using the caliper sensor, and identifying an error between the measurement of the known distance and the known distance.
