  • Patent number: 9060658
    Abstract: Disclosed are a mobile robot with a single camera capable of performing a cleaning process with respect to surroundings, and capable of more precisely making a 3D map of the surroundings including a plurality of feature points, and a method for recognizing 3D surroundings of the same. According to the method, images of the surroundings are captured, and a preset number of particles with respect to feature points of a first image are projected to a second image based on matching information of feature points extracted from the two images sequentially captured, thereby extracting 3D information of the surroundings.

  • Patent number: 8954191
    Abstract: Disclosed is a mobile robot and a controlling method of the same. An entire movement region is divided into a plurality of regions, and a partial map is gradually made by using feature points of a plurality of images of the divided regions. Then, the map is compensated into a closed curved line, thereby making an entire map. Furthermore, when the mobile robot is positioned at a boundary of neighboring regions of the cleaning region, the boundary where a closed curved line is formed, the mobile robot compensates for its position based on a matching result between feature points included in the map, and feature points extracted from images captured during a cleaning process.

  • Patent number: 8798792
    Abstract: A method for controlling a robot cleaner includes: detecting a cleaning target space, setting a cleaning region within the detected cleaning space and cleaning the set cleaning region; if the set cleaning region is completely cleaned, moving to a not-yet-cleaned region adjacent to a cleaning completion spot of the cleaning region; and setting a new cleaning region in the not-yet-cleaned region and performing cleaning. Without repeating a cleaning region in the cleaning target space, the robot cleaner can extend its cleaning region, so the cleaning efficiency of the robot cleaner can be improved. Also, the robot cleaner can be smoothly enter a new cleaning target space or released therefrom. In particular, even when the entrance of the new cleaning target space is narrow, the robot cleaner can smoothly enter the new cleaning target space and gets out thereof.

  • Patent number: 8676380
    Abstract: There are provided a moving robot and a method of operating the same. A bottom surface is photographed to sense a moving distance and a moving direction based on input image data. The amount of light radiated to photograph the bottom surface is sensed to feedback control the light emission degree of a light source unit. The light source unit is controlled when errors are generated in sensing the image data. Therefore, the sensing ratio of the photographed image is improved so that correctness of calculating the position of the moving robot is improved.

  • Patent number: 7362882
    Abstract: The invention relates to a method for generating a computed digital image of a scene, which can be illuminated with different luminous intensities at a first illumination angle by a first light source. An image sensor records a number of individual images of the scene under different lighting conditions, and these images are set against one another in a pixel-by-pixel manner in a data processing device in order to generate a resulting image. The invention is characterized in that at least one additional light source is provided by means of which the scene can be illuminated at an illumination angle that is different from the illumination angle of the first light source. The different lighting conditions when recording the individual images are obtained by various combinations of luminous intensities of the first and of the at least one other additional light source. The invention also relates to a device for carrying out the inventive method.
