摘要:
A method and an apparatus for controlling a convergence distance for observation of a 3-D image are provided. The apparatus includes an object image storage, a guide image storage, an image synthesizer, and a controller. The object image storage stores object image data generated by photographing 3-dimensionally an object positioned at an object image point. The guide image storage stores guide image data generated by sequentially moving back and forth of the object image point and photographing 3-dimensionally a guide object. The image synthesizer receives the object image data and the guide image data to generate a synthesized image. The controller controls to sequentially output the guide image data and if a photographing distance of the guide image data coincides with an object image point, controls to stop the outputting of the guide image data so that a convergence distance of an observer may coincide with the object image point.

Technology for creating a feature map for localizing a mobile robot and extracting feature information of surroundings is provided. According to one aspect, feature information including a reflection function is extracted from information acquired using a 3D distance sensor and used as a basis for creating a feature map. Thus, a feature map that is less sensitive to change in the surrounding environment can be created, and a success rate of feature matching can be increased.

An obstacle detecting apparatus and a method thereof, which are usable in an autonomous moving robot, are provided. The obstacle detecting apparatus extracts at least one plane from measured range data, extracts at least one intersection point and at least one intersection line using at least one plane, and extracts matching data neighboring at least one intersection point and at least one intersection line from the range data. The matching data is extracted by reflecting uncertainties of the intersection point and the intersection line extracted from the measured range data. Matching is performed between the extracted matching data and model data, and an obstruction is detected by using the matching result.
