摘要： A first device includes: a first reference signal source; a first transmitting/receiving unit which transmits two or more first carrier signals and receives two or more second carrier signals using an output of the first reference signal source; and a calculating unit. A second device includes: a second reference signal source configured to be operated independently from the first reference signal source; and a second transmitting/receiving unit configured to transmit two or more second carrier signals and receive two or more first carrier signals using an output of the second reference signal source. A frequency group of two or more first carrier signals and a frequency group of two or more second carrier signals differ from each other. The calculating unit calculates a distance between the first device and the second device based on a phase detection result obtained by receiving the first and second carrier signals.

摘要： According to an arrangement, an estimation device (20, 20-2) includes a storage unit (20B), an acquisition unit (21), and an estimation unit (22), and the estimation unit (22). The storage unit (20B) stores therein first position information indicating at least a position or a pose of a first landmark in a map. The acquisition unit (21) acquires second position information indicating at least a position or a pose of a second landmark in a neighborhood of a moving object. The estimation unit (22) estimates third position information and correspondence between the first landmark and the second landmark, based on the first and second position information, where the third position information indicates at least a position or a pose of the moving object in the map. The third position information and the matching are estimated such that an observation error of the second landmark in at least the position or the pose specified by the third position information and a matching error are reduced.

摘要： A distance measuring device according to an embodiment is a distance measuring device that performs processing on a time-series luminance signal generated on the basis of a sensor output corresponding to reflected light of laser light. The distance measuring device includes a storage circuit and a determination circuit. The storage circuit stores a first time-series luminance signal based on reflected light from a first measurement target of laser light and a second time-series luminance signal based on reflected light from a second measurement target of laser light. The determination circuit determines, on the basis of correlation between the first time-series luminance signal and the second time-series luminance signal, whether the first measurement target and the second measurement target are the same measurement target.

摘要： A distance measuring device according to an embodiment that processes a first time-series luminance signal generated on the basis of a sensor output corresponding to reflected light of laser light, includes a measurement signal generation circuit, and a measurement processing circuit. The measurement signal generation circuit generates a third time-series luminance signal obtained by subtracting, from the first time-series luminance signal, a second time-series luminance signal corresponding to reflected light from outside a measurement target object based on the laser lightl. The measurement processing circuit generates a distance value to the measurement target object on the basis of the third time-series luminance signal.

摘要： According to one arrangement, a gradient estimation device (20, 20-2) includes an acquisition unit (201), an extraction unit (203, 203-2), a calculation unit (204). The acquisition unit (20, 20-2) acquires a first image and a second image obtained by photographing a surface of an object. The extraction unit (203, 203-2) extracts, from the first image, a first pixel indicating a boundary of an object in a direction different from a gradient direction of the surface, and extract a second pixel corresponding to the first pixel from the second image. The calculation unit (204) calculates gradient magnitude of the surface by transforming at least one of the first image and the second image such that a matching degree between the first pixel and the second pixel is increased.
