Abstract: An autonomous mobile apparatus includes a controller, an image acquirer, an inertia measurer, a distance measurer, and a storage. The controller updates environment map information stored in the storage. The controller estimates a height from a reference surface, based on an image obtained by the image acquirer. The inertia measurer detects an amount of fluctuation of the height. The distance measurer detects whether or not the bottom portion of the autonomous mobile apparatus is in contact with an object. The controller, if having detected a change in height equal to or larger than a reference from information obtained from the image acquirer, the inertia measurer, or the distance measurer, stops updating the environment map information or deletes the environment map information.

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.

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. In another aspect, 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 and a search range setting means that utilizes an already extracted boundary line extracted by the boundary line extraction means to dynamically set a search range for another 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.
