  • Patent number: 11087145
    Abstract: According to one embodiment, a gradient estimation device includes one or more processors. The processors acquire a first image and a second image obtained by photographing a surface of an object. The processors extract, 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 processors calculate 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.

  • Patent number: 10976438
    Abstract: According to an embodiment, a device includes processing circuitry. The processing circuitry performs three-dimensional measurement of surroundings of a mobile object to obtain a three-dimensional point group. The processing circuitry calculates movement information. The processing circuitry makes a threshold value based on time series differences in the movement information. The processing circuitry extracts, from the three-dimensional group, three-dimensional points having distance to the mobile object in a moving direction of the mobile object to be equal to or smaller than the threshold value. The processing circuitry divides space, in which the three-dimensional points are present, into divided spaces in the moving direction. The processing circuitry selects a representative point for the divided space from among three-dimensional points included in the divided space.
