摘要： In a non-contact discharge test performed in a poor electromagnetic noise environment, the energy of discharge is evaluated by detecting weak light emission and processing the intensity waveform of light emission of the discharge. A database is created by measuring the intensity waveform of light emission of discharge generated as a result of application of a voltage or current to a measurement object through use of a light emission measuring device, simultaneously measuring the current waveform of the discharge through use of a current measuring device, and storing in the database the relation between analysis data sets obtained through analysis of the waveforms on the basis of information of the voltage or current applied to the measurement object. The intensity waveform of the light emission of the discharge or spark generated from the measurement object is measured while an electromagnetic wave generated as a result of the discharge of the measurement object is used as a reference. The magnitude of the discharge is estimated as a value by comparing light emission data obtained through analysis of the intensity waveform with the data recorded in the database.

摘要： In an object detecting method according to an embodiment, external reference points are set in external space of a model of an object and an internal reference point is set in internal space of the model. A table is stored in which feature quantities on a local surface of the model are associated with positions of the external reference points and the internal reference point. The feature quantity on the local surface of the model is calculated, and the position of the reference point whose feature quantity is identical to the calculated feature quantity is acquired from the table and is converted into a position in a real space. When the converted position is outside the object, the position is excluded from information for estimation and the position and the attitude of the object are estimated.

摘要： A tracking device includes full-spherical cameras arranged on the right and left. The tracking device pastes a left full-spherical camera image captured with the full-spherical camera on a spherical object, and is installed with a virtual camera inside the spherical object. The virtual camera may freely rotate in a virtual image capturing space formed inside the spherical object, and acquire an external left camera image. Similarly, the tracking device is also installed with a virtual camera that acquires a right camera image, and forms a convergence stereo camera by means of the virtual cameras. The tracking device tracks a location of a subject by means of a particle filter by using the convergence stereo camera formed in this way. In a second embodiment, the full-spherical cameras are vertically arranged and the virtual cameras are vertically installed.

摘要： According to one implementation, an inflammable spark estimation system includes: a photodetector for measuring intensity of discharge light arising from a spark arising from a structural object made of a plurality of materials; and a data processing system configured to determine whether the spark has inflammability, based on the intensity of the discharge light measured by the photodetector, with referring to determination information. The determination information has been determined based on features of waveforms of wavelength spectra of possible discharge light arising from possible inflammable sparks respectively arising from possible materials of which the structural object may be made. The data processing system is configured to further determine which of the plurality of the materials the spark has arisen from, based on the intensity of the discharge light measured by the photodetector, with referring to the determination information, when the spark has been determined to have the inflammability.

摘要： A state estimation system for a power conversion semiconductor apparatus in an embodiment includes an analysis processing unit and an estimation processing unit. The analysis processing unit projects points indicating a combination of a voltage detection value in first time history data of a voltage between the pair of main terminals detected when the pair of main terminals are forward-biased and when the pair of main terminals are reverse-biased and a current detection value in second time history data of detection values of both a forward current and a reverse current between the pair of main terminals onto a coordinate plane including a voltage axis and a current axis on the basis of the first time history data and the second time history data in the power conversion semiconductor apparatus including the pair of main terminals and derives a distribution of the projected points on the coordinate plane. An estimation processing unit estimates a state of the power conversion semiconductor apparatus on the basis of a distribution of the projected points.
