  • Patent number: 10296002
    Abstract: The movement direction-and-speed determiner of an autonomous movement device determines the direction and speed for an autonomous movement based on information on the plurality of picked-up images by an image picker. A feature point obtainer obtains a feature point from the picked-up image by the image picker. A map memory stores the position of the obtained feature point by the feature point obtainer. A corresponding feature-point number obtainer obtains the number of correspondences between the obtained feature point by the feature point obtainer and the feature point having the position stored in the map memory. When the obtained number of corresponding feature points by the corresponding feature-point number obtainer is equal to or smaller than a threshold, in order to increase the number of corresponding feature points, a moving direction-and-speed changer changes the moving direction and speed to those determined by the movement direction-and-speed determiner.

  • Publication number: 20190011929
    Abstract: An autonomous mobile apparatus includes a driving unit, a memory including a map memory, and a processor. The processor is configured to estimate an apparatus location based on information from the driving unit and estimate the apparatus location based on information from other than the driving unit. The processor is configured to acquire a location of an object around the autonomous mobile apparatus, create an environment map based on the estimated apparatus location and the acquired object location, and store the environment map in the map memory. The processor is configured to use, at a time of tracking when the estimation of the apparatus location based on the information from other than the driving unit is enabled, the environment map that is in the map memory at a time of reference determined by a time of loss when the estimation of the apparatus location is not enabled.

  • Publication number: 20190004520
    Abstract: An autonomous movement device includes an obstacle detector, a map creator, an obstacle canceller, and a router. The obstacle detector detects an obstacle. The map creator records information about the obstacle detected by the obstacle detector on an environment map. The obstacle canceller cancels the information about the obstacle recorded by the map creator from the environment map. The router sets a moving route based on the information recorded on the environment map.

  • Publication number: 20180240240
    Abstract: The image processing apparatus includes a boundary line extraction means that extracts a boundary line of a layer from an input image obtained by capturing an image of a target object composed of a plurality of layers. The boundary line extraction means is configured to first extract boundary lines at upper and lower ends of the target object, limit a search range using the extracted boundary lines at the upper and lower ends to extract another boundary line, limit the search range using an extraction result of the other boundary line to extract still another boundary line, and then sequentially repeat similar processes to extract subsequent boundary lines.

  • Publication number: 20180232886
    Abstract: Edges of layers are detected from an input image to create a boundary line candidate image that represents the detected edges. A luminance value of the input image is differentiated to create a luminance value-differentiated image that represents luminance gradient of the layers. An evaluation score image is created which is obtained by weighting calculation at an optimum ratio between a boundary line position probability image and the luminance value-differentiated image. The boundary line position probability image is obtained from the boundary line candidate image and an existence probability image that represents existence of a boundary line to be extracted. A route having the highest total evaluation score is extracted as the boundary line. According to such an image processing apparatus and image processing method, boundary lines of layers can be extracted with a high degree of accuracy from a captured image of a target object composed of a plurality of layers.
