Patent number: 10902610Abstract: The position of a moving object is estimated with high accuracy using landmark information, and highly accurate state estimation is performed appropriately at high speed. A landmark detection unit obtains a distance between the moving object and each of two or more landmarks as landmark distance information based on observation data obtained by an observation obtaining unit. A candidate area obtaining unit determines a candidate area for a position of the moving object based on the landmark distance information obtained by the landmark detection unit, and obtains candidate area information indicating the determined candidate area. A state estimation unit estimates an internal state of the moving object based on the observation data, the landmark distance information, and the candidate area information to obtain moving object internal state estimation data, and estimates the environmental map based on the candidate area information and the landmark distance information to obtain environmental map data.Type: GrantFiled: December 19, 2018Date of Patent: January 26, 2021Assignees: MEGACHIPS CORPORATION, KYUSHU INSTITUTE OF TECHNOLOGYInventors: Kenta Nagamine, Norikazu Ikoma, Fumiya Shingu, Hiromu Hasegawa

Patent number: 9792697Abstract: A state estimation apparatus appropriately estimates the internal state of an observation target by calculating a likelihood from observation data, and tracks, for example, multiple objects in a moving image and detects a new object and adds the object as a tracking target in an appropriate manner. A labeling unit detects a closed area from an observation image, and adds a label number to the closed area to generate a label image. A likelihood obtaining unit generates an object-erased image for new object detection by erasing image areas corresponding to all the currently-tracked objects. The apparatus performs the process for detecting a new object using the object-erased image for new object detection based on label numbers. The apparatus is appropriately prevented from erroneously determining that an area of the object-erased image for new object detection corresponding to the currently-tracked object and remaining after the erasure corresponds to a new object.Type: GrantFiled: February 5, 2015Date of Patent: October 17, 2017Assignee: MegaChips CorporationInventors: Kenta Nagamine, Hiromu Hasegawa
