A situation identification method includes acquiring a plurality of images; identifying, for each of the plurality of images, a first area including a bed area where a place to sleep appears in an image, and a second area where an area in a predetermined range around the place to sleep appears in the image; detecting a state of a subject to be monitored for each of the plurality of images based on a result of detection of a head area indicating an area of a head of the subject in the first area and a result of detection of a living object in the second area; when the state of the subject changes from a first state to a second state, identifying a situation of the subject based on a combination of the first state and the second state; and outputting information that indicates the identified situation.

Localization and map building apparatus and method applicable to a mobile robot are provided. In an exemplary embodiment, a map building apparatus extracts a pattern of landmarks of the same kind and adjusts a landmark map using the extracted pattern when generating the landmark map for localization. Accordingly, since the landmark map is adjusted based on the pattern extracted on the basis of location information of each landmark, accuracy of localization and map building of the mobile robot can be improved.

A feature value extraction apparatus, a method, and a program capable of extracting local feature values whose positions are unchanged, and a place estimation apparatus, a method, and a program equipped with them are provided. A place estimation apparatus (10) performs a place estimation process by using position-invariant feature values extracted by a feature value extraction unit (11). The feature value extraction unit (11) includes local feature value extraction means (21) for extracting local feature values from each of input images formed from successively-shot successive images, feature value matching means (22) for obtaining matching between successive input images based on the extracted local feature values, corresponding feature value selection means (23) for selecting matched feature values as corresponding feature values, and position-invariant feature value extraction means (24) for obtaining position-invariant feature values based on the corresponding feature values. The position-invariant feature value extraction means (24) extracts, from among the corresponding feature values, corresponding feature values whose position change is equal to or less than a predetermined threshold as the position-invariant feature values.

Provided are an image capturing unit (10) that captures an image of a predetermined space; an image acquiring unit (11) that acquires the image captured by the image capturing unit (10); a mask region deriving unit (24) that derives, by using the image acquired by the image acquiring unit (11), a mask region not to be sensed from the image; a detection region deriving unit (26) that derives, by using the image acquired by the image acquiring unit (11), a detection region of each type as a sensing target from the image; a retaining unit (12, 13) that retains the mask region and the detection region as setting information; and a sensing unit (14) that senses a state of the space from the image acquired by the acquiring unit based on the setting information retained in the retaining unit (12, 13).
摘要:
To carry out satisfactory object recognition in a short time. An object recognition method in accordance with an exemplary aspect of the present invention is an object recognition method for recognizing a target object by using a preliminarily-created object model. The object recognition method generates a range image of an observed scene, detects interest points from the range image, extracts first features, the first features being features of an area containing the interest points, carries out a matching process between the first features and second features, the second features being features of an area in the range image of the object model, calculates a transformation matrix based on a result of the matching process, the transformation matrix being for projecting the second features on a coordinate system of the observed scene, and recognizes the target object with respect to the object model based on the transformation matrix.
