A movement assisting device includes an imaging unit to take first and second images of an imaging unit from first and second viewpoints; a first calculator to calculate, using the first and second images, first position and orientation of the imaging unit at the first viewpoint and calculate second position and orientation of the imaging unit at the second viewpoint; a second calculator to calculate, using the first and second positions and the first and second orientations, and calculate a first angle between a first axis based on a first optical axis of the imaging unit at the first viewpoint, and a second axis based on a second optical axis at the second viewpoint; a third calculator to calculate the next viewpoint positioned in direction of increase of the first angle; and an output unit to output information prompting movement of the imaging unit in direction of the next viewpoint.

Movement assisting device, movement assisting method, and computer program product

According to an embodiment, a measuring device includes a projector, an image capturing unit, and a first calculator. The projector projects, onto a target, a first superimposed pattern which is obtained by superimposing a first pattern having a periodic change and a second pattern configured with a first design for specifying a period of the first pattern. The image capturing unit captures the target, onto which the first superimposed pattern is projected to obtain an image. The first calculator performs matching of the first design taken by the image capturing unit, which is included in the first superimposed pattern in the image, with the first design projected by the projecting unit, and calculates correspondence between a second superimposed pattern, which points to the first superimposed pattern captured in the image, and the first superimposed pattern.

Measuring device, measuring method, and computer program product

According to an embodiment, a feature calculation device includes an obtaining unit, a first calculator, and a second calculator. The obtaining unit is configured to obtain a point sequence group comprising a set of point sequences in which a sequence of a plurality of points is fixed. The first calculator is configured to, for each of the point sequences in the point sequence group, calculate a plurality of values related to a curvature of a shape of the point sequence, with a reference point of the point sequence as a reference, and calculate feature quantities based on the plurality of calculated values. The second calculator is configured to calculate a histogram representing a distribution of the feature quantities of each of the point sequences.
