Document Type and Number:
Japanese Patent JP6888559
Kind Code:
B2
Abstract:
To provide a shape estimation device that realizes shape estimation of an object using a plurality of directional distance sensors moving.SOLUTION: A shape estimation device comprises: acquisition means 101 that acquires a sensing result for a plurality of directional distance sensors 20 linearly moving at a predetermined speed in a predetermined area to individually sense an object existing in the area; extraction means 102 that extracts a feature parameter representing a segment interval satisfying a predetermined condition among the segment intervals included in a sensing result acquired by the acquisition means or the intervals which is like a segment as a result normalized by the speed; first estimation means 111 that estimates a segment length of the segment included in a contour of the object and a vertex angle of the contour of the object on the basis of a feature parameter extracted by the extraction means; and second estimation means 112 that estimates a connection relation between the segment of the segment length estimated by the first estimation means and a vertex of the vertex angle.SELECTED DRAWING: Figure 4
