Title: Apparatus and method for recognizing self-position in robort system
Inventor: KIM IN KWANG
IPC: G06T7/00
Filed: 2000-07-28
Abstract: PURPOSE: A self-localization apparatus and method in a robot system is provided to exactly and efficiently recognize the current location of a robot by comparing directional reflected distance information calculated for each direction an electronic compass points with directional reflected distance information at the locations of estimated candidate cells on a virtual map for a previously obtained building structure. CONSTITUTION: A self-localization apparatus consists of a 360 deg. rotation laser reflected distance detector(100), a controller(101), and a direction detection part(102). The 360 deg. rotation laser reflected distance detector(100) divides 360 deg. of a laser signal equally and outputs the signal to each of the equally divided directions. The detector(100) detects the distance between a laser point, a point that the laser signal reaches an object, and the object for each direction using the line image data inputted as the laser signal is reflected, and outputs directional laser reflected distance information. The controller(101) divides the area of a virtual map by the cell and stores directional laser reflected distance information with each cell in the center. The controller(101) selects estimated candidate cells, compares directional laser reflected distance information at the current location with the directional laser reflected distance information of the estimated candidate cells, extracts the nearest cell, and uses it as the information of the present location. The direction detection part(102) provides absolute directional information.
