Patent application number | Description | Published |
20100004861 | Obstacle detecting apparatus and method - 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. | 01-07-2010 |
20100114374 | Apparatus and method for extracting feature information of object and apparatus and method for creating feature map - 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. | 05-06-2010 |
20110193859 | Apparatus and method for generating octree based 3D map - A method of generating a 3D complex octree map. A plurality of points each having 3D location information are detected from a range image. A space having the detected plurality of points is represented using grids. If points in a grid forms a plane, the grid is not subdivided and planar information about the plane is stored. A space not forming a plane is subdivided, thereby enhancing the storage efficiency. | 08-11-2011 |
20120302883 | METHOD AND SYSTEM FOR TREATMENT AND DIAGNOSIS USING ULTRASOUND - A method and system for treatment and diagnosis using ultrasound includes irradiating ultrasound for treatment into a treatment site, inducing a shear wave around the treatment site, irradiating ultrasound for diagnosis into the treatment site, and determining a degree of treatment or necrosis of a tissue of the treatment site by using a measured displacement of the shear wave. | 11-29-2012 |
20130317520 | SURGICAL IMPLEMENT AND MANIPULATION SYSTEM INCLUDING THE SAME - A surgical implement and a manipulation system including the surgical implement may include at least one instrument including at least one joint portion. The joint portion may include a first part, a second part connected to the first part, and a force applying element for applying a force for bending (or rotating) the second part. A distance between a joint point and a force application point where a force is applied may be greater than a diameter of at least one of the first part and the second part. The instrument may further include a second joint portion spaced apart from the joint portion, and a surgical tool connected to an end portion of the second joint portion. The manipulation system may include a supporting structure, at least one instrument supported by the supporting structure, and an operating device for operating the instrument. | 11-28-2013 |
20130317521 | SUPPORTER DEVICE AND SURGICAL ROBOT SYSTEM INCLUDING THE SAME - A supporter device supports an instrument which is inserted in an object. The supporter device includes a base member having an insertion region through which the instrument passes, a movable member installed on the base member so as to move around the insertion region, and a pivot member installed to be pivotable based on a pivot axis that passes through the insertion region, wherein the instrument may be mounted on the pivot member. A movable central axis of the movable member and an extension axis of the instrument may cross at a single crossed point. | 11-28-2013 |
20140012082 | ENDOSCOPE AND ENDOSCOPE SYSTEM - An endoscope includes a first lens unit that collects light corresponding to an object image which is an image including depth information of an object; a second lens unit that collects light corresponding to a surrounding tissue image which is an image of a surrounding tissue of the object; a switching unit that alternately applies light received from the first lens unit and the second lens unit to a photographing unit; and a photographing unit that alternately captures the light from the switching unit. | 01-09-2014 |
20160022440 | MOTION ASSISTANCE APPARATUS AND METHOD OF CONTROLLING THE SAME - A motion assistance apparatus may include a first fixing member to be fixed to a portion of a user, a second fixing member to be fixed to another portion of the user, a driving source provided in the first fixing member, a power transmitting member connected between the driving source and the second fixing member, a sensing portion configured to sense a fixing state of the first fixing member or the second fixing member, and a controller configured to control the driving source based on information received from the sensing portion. | 01-28-2016 |
