  • Patent number: 9275458
    Abstract: A method and apparatus for providing a vehicle camera calibration includes choosing overlap images from among the image information captured by a camera mounted on a vehicle, and filtering images having the same vehicle attitude from among the chosen overlap images on a basis of a map coordinate system and status information of the vehicle, picking out objects in the filtered images, separating stationary objects from the picked out objects, and predicting an angular misalignment with respect to the separated stationary objects.

  • Publication number: 20120302419
    Abstract: The present invention relates to an automatic balance adjusting centrifuge which calculates the magnitude and the location of imbalance of itself based on the vibration generated in the dynamic state and automatically compensate for the imbalance based on the calculation, and the control method thereof. The method includes: (a) measuring the amount of vibration of a rotor of a centrifuge, supporting buckets that load samples, at a predetermined rotational velocity; (b) determining whether the amount of vibration measured in step (a) is greater than an allowed value; and (c) when the amplitude of the vibration is greater than the allowed value, compensating for a weight imbalance of the rotor by an amount calculated based on the vibration amount measured in step (a) and returning to step (a), otherwise, performing a centrifugal separation by accelerating the rotor to a working velocity.

  • Publication number: 20080133554
    Abstract: Provided is a method for storing multipurpose geographic information, capable of integrating, storing, managing and using vector data (numerical map) and image, digital elevation model (DEM), three-dimensional (3D) point cloud data, and facility texture information. The method for storing multipurpose geographic information in a computing system includes the steps of: dividing geographic information data to be stored into minimum units; classifying the divided geographic information data into geometric information (geographic position information) and attribute information; and storing the geometric information (geographic position information) in a vector format and storing the attribute information in an attribute information linked to a vector.
