Abstract:
PURPOSE: A method for removing a line of an internal structure for a ceiling vision-based SLAM(Simultaneous Localization And Mapping) algorithm is provided to distinguish the line of the internal structure from walls and ceiling areas when the ceiling vision-based SLAM(Simultaneous Localization And Mapping) algorithm is implemented, thereby removing the distinguished line. CONSTITUTION: First and second motion vectors are obtained. The first motion vector shows movement of a ceiling area feature point. The second motion vector shows movement of a boundary line feature point. The first motion vector is compared with the second motion vector. When the first motion vector is different from the second motion vector(e), a boundary line is determined as a boundary line by an internal structure and is removed(f).
Abstract:
PURPOSE: An accident detecting system based on the sensor network and method thereof are provided to minimize needed information for workforce by having sensor nodes autonomically recognize and determine accidents. CONSTITUTION: A plurality of sensor node(100) collects a limited range of images and extracts object information of specific objects. At least a master node(200) generates integrated information by integrating each object information. A server(300) receives integrated information from the master node and infers whether an accident happens or not based on the integrated information.
Abstract:
PURPOSE: A robot designing apparatus and a method thereof using a pop-up primitive mode are provided to easily design a joint part which connects each component of a robot. CONSTITUTION: An input unit(10) inputs a selection signal of a user. A component design unit(41) designs a first component of a robot according to the selection signal of the user through the input unit. The component design unit designs a second component in a pop-up mode. A joint design unit(43) selects a connection mode of a joint, an operation range, or an eccentricity range according to the selection signal of the user.
