Abstract: Disclosed is an image-based cooperative simultaneous localization and mapping system and method by using rendezvous. An embodiment of the present invention provides an image-based cooperative simultaneous localization and mapping method in a multi-platform system, the method comprising the steps of: estimating a camera posture on the basis of an image input through a camera in a single SLAM scheme and manufacturing an local map by each of multiple platforms; extracting a non-static feature from the image and managing same; transmitting, to a ground station, the camera posture, the local map, and the non-static feature as platform data; determining, by the ground station, whether a rendezvous situation has occurred between one of the multiple platforms and the remaining platforms, on the basis of the platform data; and when the rendezvous situation occurs, fusing the local map received from two or more rendezvoused platforms into a global map.

Abstract: Provided is a flight vehicle and in particular a flight vehicle in which a main module equipped with a device capable of carrying cargo, photographing, etc. may freely switch directions during flight while applying a posture independent of a thrust module because the thrust module is configured to freely perform roll and pitch motions with respect to the main module.

Abstract: A processor-implemented method of detecting a moving object includes: estimating a depth image of a current frame; determining an occlusion image of the current frame by calculating a depth difference value between the estimated depth image of the current frame and an estimated depth image of a previous frame; determining an occlusion accumulation image of the current frame by adding a depth difference value of the occlusion image of the current frame to a depth difference accumulation value of an occlusion accumulation image of the previous frame; and outputting an area of a moving object based on the occlusion accumulation image.

Abstract: The present invention relates to an apparatus and a method for steering a vehicle, and more particularly to an apparatus and a method for steering an autonomous vehicle. One aspect of the present invention provides a method of steering a vehicle in an apparatus for steering the vehicle, the method comprising: (a) determining a first path by using a starting point and a destination of the vehicle; (b) generating an obstacle position signal when a plurality of obstacle sensors mounted on the vehicle detect an obstacle during an operation of the vehicle; (c) generating a parallax information using the obstacle position signal received from the plurality of the obstacle sensors; and (d) determining a second path avoiding the obstacle by using the parallax information. According to the method and the apparatus for steering a vehicle of the present invention, a vehicle may avoid obstacles in real-time in complex environments.

Abstract: The present invention relates to a drawer-type washing machine and a locking method thereof. The washing machine includes a housing having one open side and partitioned into a plurality of compartments; cabinets which can be drawn out forward through the open side of the housing, each of the cabinets being positioned in each of the compartments; washing baths for washing the laundry, each of the washing baths being positioned within each of the cabinets; and locking mechanism provided between the housing and the cabinets for restraining the cabinet from being drawn out forward from the housing. The cabinets are automatically drawn out by only operating a switch installed in an outside wall of the housing.

Abstract: A drawer-type washing machine and process of washing laundry using the washing machine is disclosed. The washing machine has a housing opened at its front to form a cavity. A cabinet, opened at its top, is received in the cavity of the housing such that the cabinet is movable forward or backward relative to the housing. A washing tub unit, consisting of an outer tub and an inner tub, is set within the cabinet. This washing tub unit contains washing water therein, and carries out both a washing operation and a spin-drying operation for laundry contained therein. A drive unit is installed at a position under the outer tub of the washing tub unit, and rotates the inner tub of the washing tub unit. A suspension unit supports the washing tub unit within the cabinet while performing a damping function of attenuating operational vibrations of the washing tub unit.
