    摘要: Disclosed is a system and method for calculation a location in a real-time manner using a combination of odometry and artificial landmarks. The system for calculating a location comprising a landmark detection unit detecting an image coordinates value of the artificial landmark corresponding to a location in a two-dimensional image coordinate system with respect to a mobile robot from an image obtained by photographing a specific space where the artificial landmarks are provided; a landmark identification unit comparing a predicted image value of the artificial landmark, obtained by converting a location coordinates value of the artificial landmark into an image coordinates value corresponding to the location in the two-dimensional image coordinate system with respect to a location coordinates value corresponding to a location in an actual three-dimensional spatial coordinate system of the mobile robot, with an image coordinates value detected by the landmark detection unit to detect the location coordinates value of the artificial landmark; a first location calculation unit calculating a current location coordinates value of the mobile robot using a predetermined location calculation algorithm based on the image coordinates value detected by the landmark detection unit and the location coordinates value detected by the landmark identification unit; a second location calculation unit calculating a current location coordinates value of the mobile robot using a predetermined location calculation algorithm based on odometry information of the mobile robot; and a main control unit updating the current location coordinates value of the mobile robot, using the location coordinates value calculated by the first location calculation unit when the location coordinates value calculated by the first location calculation unit exists, or using the location coordinate value obtained from the second location calculation unit when the location coordinates value calculated by the first location calculation unit does not exist.

    摘要: A path search method of a mobile object in a grid map having a plurality of cells, each having an identical size, is provided. The path search method includes: generating a block map having a plurality of blocks by merging a specific number of cells in the grid map; obtaining a block path by finding a path from a starting position to a destination position in the block map; and obtaining a final path of the mobile object by performing a cell-based path search on cells in the blocks on the block path.

    摘要: A method of navigating a robot includes creating a robot navigation map using a map database required for navigation of the robot; and creating a path on which no obstacle is located in the map database using the created robot navigation map. Further, the method of navigating the robot includes primarily controlling the robot so that the robot travels along the created path; and secondarily controlling the robot so that the robot avoids an obstacle on the path.
