摘要： A method for verifying the accuracy of a CNC machine or a CMM. The methodology segregates the measured error into an assignable cause portion and a common cause (or random error) portion. The methodology may be employed to affect the calibration of the machine tool to factor out the mean value of the assignable cause portion. Inherent in this methodology is the ability to diagnose mechanical problems with the CNC machine or CMM that affects the repeatability and accuracy of such machine tools; identify degradation in the performance of such machine tools that is indicative of mechanical failure; and improve the accuracy and repeatability of such machine tools in certain situations.

The simulator has a radiation source (8) arranged so as to emit a beam along a simulation axis, and adjusting means (10) for adjusting the simulation axis so that it is aligned with the weapon sight. The system is characterized in that it includes a sighting mark at which the weapon sight is to be aimed during alignment, and means arranged in connection with the sighting mark to emit a beam along an axis representing an aligned simulation axis. The system further includes an aligning unit (14) that is deployable at the simulator and in which at least a first part of the beam from the element (8) is reflected along an axis representing the current position of the simulation axis. Position-indicating means (18) are arranged so that the beam alone the axis representing the aligned beam strikes the position-indicating means (18) at a point representing a set-point value for the simulation axis, and so that the beam along the axis representing the current simulation axis strikes the position-indicating means at a point representing an actual value for the simulation axis.

摘要： The invention is a method of calibrating the sensor system of a wideband direction finder using a noise source. The sensor system includes at least two wideband tuners, and an analog/digital (A/D) converter connected to each wideband tuner. The calibration method involves selecting a common set of center frequencies for each of the wideband tuners. The wideband tuners receive a signal from the noise source on a per data frame basis. The passband of the received signal is then divided into a number of time-sampled data frames. For each time-sampled data frame, both a gain variation and a phase variation are calculated for the noise received at each wideband tuner. Gain and phase differences between the signal received by each wideband tuner within the same frame are compared. Based on the time-sampled data collected, the phase and gain differences for the signals received at the tuners which have not been previously mapped can be determined. As a result, this calibration method determines a series of calibration factors for each frame, and for a wide range of frequencies.

摘要： An apparatus and method for calibrating machine vision measuring systems that have more than one camera are disclosed. A first calibration target is mounted in a fixed relationship to a first camera of the machine vision measuring system. A third camera mounted in a fixed relationship to a second camera of the machine vision measuring system. Second and third calibration targets are mounted in a fixed relationship to one another and viewable by the first camera and by the third camera. A data processor is programmed to compute calibration of the first camera and the second camera, based on a position of the second calibration target relative to the third calibration target and based on a position of the first camera with respect to the third camera. The apparatus and method provide a way to continuously measure the positions of two or more cameras used in the measuring system, and to use such measurements to calibrate the system. If the cameras move with respect to each other, their respective positions are calculated and used in subsequent measurements. The apparatus and method enable a machine vision measuring system to be used without field calibration at the time of installation.

摘要： First A.C. output signal sin(nulltnullnull) having an electric phase angle shifted in a positive direction in accordance with a position-to-be-detected is produced along with a second A.C. output signal sin(nulltnullnull) having an electric phase angle shifted in a negative direction. First and second detection data are generated by detecting respective phase differences (nullnull and nullnull) of the first and second A.C. output signals from a predetermined reference phase. First predicted value is provided on the basis of at least two successive samples of the first detection data, and a second predicted value is provided on the basis of at least two successive samples of the second detection data. The first and second predicted values are modified to provide a standard predicted value for correcting a nonlinear error resulting from the Doppler effect. Using this standard predicted value, predictive interpolation is performed on the first and second detection data sequentially with the passage of time, so as to provide first and second interpolated detection data. With this arrangement, it is possible to achieve improved response and detection performance with respect to dynamic characteristics. Error due to a temperature change or the like may be eliminated by performing an arithmetic operation on the first and second interpolated detection data, so that temperature drift characteristics can be improved.

摘要： A view transformation matrix that represents the position/attitude of an HMD is generated based on a signal that represents the position/attitude of the HMD (S602). On the other hand, landmarks and their locations are detected based on a captured picture (S604) and a calibration matrix nullMc is generated using the detected locations of the landmarks (S605). The position/attitude of the HMD is calibrated using the view transformation matrix and calibration matrix nullMc generated by the above processes (S606), a picture of a virtual object is generated based on external parameters that represent the position/attitude of the calibrated HMD, and a mixed reality picture is generated (S607). The generated mixed reality picture is displayed in the display section (S609).

摘要： The invention relates to a method for increasing the positioning accuracy of an element (13) which is movably arranged relative to a stator (10). At least two sensors (11, 12) are provided in the stator (10), a first sensor (11) and a second sensor (12), which are arranged at a distance (a) from one another in the stator (10), with respect to the movement direction (P) of the movably arranged element (13). The element (13) which is arranged such that it can move relative to the stator (10) is provided with encoders (130) which can move together with the movable element (13) and, when the element (13) carries out a movement relative to the stator (10), firstly produce a sensor signal (S11) in the first sensor (11) and then, as the movement of the element progresses, produce a sensor signal (S12) in the second sensor (12). First of all, in a calibration run, the movable element (13) is moved over the entire possible range of movement. During this movement, the sensor signals (S11, S12) of the first sensor (11) and of the second sensor (12) as well as the associated nominal positions of the movable element (13) are detected. The spatial distance (A) is then determined which corresponds to two sensor signals (S11, S12), which are of equal magnitude, follow one another and are caused by the same encoder, of the first sensor (11) and of the second sensor (12). The error (F) of the nominal position of the movable element is then determined from the spatial distance (A) determined in this way, from the actual distance (a) between the sensors and from the associated nominal positions, and is taken into account in the positioning of the movable element (13).

摘要： There is described a method for controlling a navigation device, such as a satellite navigation device like a GPS, GLONASS, GALILEO or other receiver, and a navigation device allowing this control method to be implemented. According to the invention, the operation of the navigation device is adjusted as a function of a measurement of the velocity (v) of the navigation device for the purpose of saving energy. In particular, the operating frequency (fck) of the processing unit (18) with which the navigation device is fitted is adjusted to a plurality of so-called reduced operating frequencies (fck2, fck3, fck4, fck5) lower than said normal operating frequency (fck1) as a function of the value of said velocity measurement (v). The invention is intended in particular to allow a navigation device to be integrated in a portable object of small volume powered by a battery or a rechargeable accumulator, such as a timepiece.

摘要： Method and system for efficiently checking and verifying the positions of components on an object such as a circuit board using a probe apparatus. A component of the object, positioned at a particular location on the object, is selected by the user using the probe apparatus. Reference information about a correct component positioned at the location of the selected component is displayed or otherwise provided, and the displayed reference information is compared with the selected component to determine if the selected component is of the correct type and value. Preferably, the selecting is accomplished by moving a probe tip of the probe apparatus within a predetermined distance of the selected component and activating a control, such as a button. The user can initiate a verify signal or a failure signal depending on whether the selected component matches the reference information.

摘要： A method for measuring a directional of a body in a three-dimensional space defined by an X-axis (magnetic north), a Y-axis, and a Z-axis is proposed. An x-axis tilt angle, which is an angle between a horizontal plane and an x-axis, which is the direction towards which the body points, and a y-axis tilt angle, which is an angle between a y-axis orthogonal to the x-axis and the horizontal plane, are detected. The x-axis and the y-axis are converted so as to be in the horizontal plane using the x-axis tilt angle and the y-axis tilt angle. A primary azimuth between the X-axis and the x-axis converted is calculated. An azimuth error angle included in the primary azimuth is extracted based on the x-axis tilt angle, the y-axis tilt angle, and the primary azimuth.
