According to one embodiment, a reading system includes a calculator and a determiner. The calculator calculates a total value of luminances and fluctuation of the luminances in at least a portion of a second direction at each of a plurality of points in a first direction for at least a portion of an image subjected to a polar transformation. A meter is imaged in the image and includes a pointer, a display panel, and graduations. The pointer rotates around a rotation axis. The graduations are arranged along a circumferential direction around the rotation axis on the display panel. The polar transformation is referenced to a center of the meter. The first direction corresponds to the circumferential direction. The second direction corresponds to a diametrical direction from the center toward the graduations. The determiner uses the total value and the fluctuation to determine a position at which the pointer exists.

Reading system, reading method, and storage medium

According to one embodiment, a reading system includes an extractor, a generator, a corrector, and a reader. The extractor extracts a first candidate region from an input image. The first candidate region is of a candidate of a region in which a meter is imaged. The generator generates a rectangle around the first candidate region when an exterior form of the first candidate region is circular. The rectangle corresponds to the exterior form of the first candidate region. The corrector generates a second candidate region by using the generated rectangle to correct the exterior form of the first candidate region to approach a perfect circle. The reader reads, from the second candidate region, a numerical value indicated by the meter.

According to one embodiment, a reading support system includes a processing device. The processing device includes an extractor and a type determiner. The extractor extracts a plurality of regions from a candidate region. The candidate region is a candidate of a region in which a meter is imaged. The regions respectively include a plurality of characters of the meter. The type determiner determines a type of the meter based on positions of the regions.

Reading support system and moving body

According to an embodiment, a reading system includes a first extractor and a reader. The first extractor extracts, from an image in which a meter is imaged, a first region surrounded with a first contour, and a second region surrounded with a second contour positioned outward of the first contour. The reader calculates a first indication based on the first region, calculates a second indication based on the second region, calculates a first score relating to the first indication based on the first region, and calculates a second score relating to the second indication based on the second region.

Reading system, moving body, reading method, and storage medium

According to one embodiment, a winding device includes a supporting part, a pressing part, a movement part configured to move a positional relationship between the supporting part and the pressing part, a control part, a target movement speed calculation part configured to detect a target relative movement speed of the pressing part with respect to the supporting part, a wire feed speed detection part configured to detect a feed speed of the wire, a deviation amount calculation part configured to calculate a difference between a detection result of the target movement speed calculation part and a detection result of the wire feed speed detection part, and a determination part configured to determine that the wire has deviated from the movement path.

Winding device and winding method

According to one embodiment, winding apparatus includes a bobbin, a core, a pressing section, a moving unit, a first rotating unit, a second rotating unit and a control unit. The moving unit is configured to move the pressing section relatively to the core along each of first to third axes perpendicular to each other. The first rotating unit is configured to rotate the pressing section relatively to the core around fourth and fifth axes perpendicular to each other, and set on the core. The second rotating unit is configured to rotate the pressing section relatively to the core around a sixth axis which becomes parallel to, when the core is in an initial position at which the fourth and fifth axes become parallel to any two of the first to third axes, a remaining one of the first to third axes.
