    • PURPOSE: A robot cleaner and a controlling method thereof are provided to recognize a position of the robot cleaner by utilizing position information of the robot cleaner and correcting a predetermined map. CONSTITUTION: A robot cleaner comprises an image input unit (50), an image processing unit (60), a position detection unit (40), a storage (70), and a control unit (80). The image input unit inputs images in a cleaning area in which is a target of the robot cleaner. The image processing unit extracts a feature point from the image which the image input unit inputs. The position detection unit detects a position of the robot cleaner by considering a transfer amount of the robot cleaner. The feature point and a predetermined map which the image processing unit extracts are stored in the storage. The control unit compares a position of the robot cleaner calculated by matching the feature point which the image processing unit extracts from a current image which the image input unit inputs and a feature point in the predetermined map, and a current position of the robot cleaner which the position detection unit detects. The control unit controls a movement of the robot cleaner based on the predetermined map when both sides are matched or corrects the predetermined map when both sides are different.

    • 目的:提供机器人清洁器及其控制方法,通过利用机器人清洁器的位置信息和校正预定的地图来识别机器人清洁器的位置。 构成:机器人清洁器包括图像输入单元(50),图像处理单元(60),位置检测单元(40),存储器(70)和控制单元(80)。 图像输入单元在作为机器人清洁器的目标的清洁区域中输入图像。 图像处理单元从图像输入单元输入的图像中提取特征点。 位置检测单元通过考虑机器人清洁器的传送量来检测机器人清洁器的位置。 特征点和图像处理单元提取的预定地图被存储在存储器中。 控制单元通过将图像处理单元提取的特征点与图像输入单元输入的当前图像和预定图中的特征点进行匹配而计算的机器人清洁器的位置与机器人清洁器的当前位置进行比较, 位置检测单元检测。 当两侧匹配时,控制单元基于预定映射来控制机器人清洁器的移动,或者当两侧不同时,校正预定映射。 (附图标记)(20)驱动单元; (21,22)第一和第二驱动马达; (23,24)第一和第二驱动轮; (30)抽油机; (31)吸油马达; (33)吸风机; (35)集尘部件; (40)位置检测单元; (50)图像输入单元; (60)图像处理单元; (70)储存; (80)控制单元
