Abstract: A method and apparatus of generating a path for autonomous navigation of a mobile computing apparatus is provided. The mobile computing apparatus includes one or more processors configured to map a set global path, which connects a current position of the mobile computing apparatus with a future destination of the mobile computing apparatus based on a topology map, to a real-time generated occupancy grid map that represents, based on sensor data of a surrounding environment of the mobile computing apparatus, an un-drivable area and a drivable area in the surrounding environment, and generate a local path, for a traveling of the mobile computing apparatus, connecting the current position with a sub-waypoint that corresponds to the drivable area in response to a next waypoint, to which the mobile computing apparatus is set to travel based on the global path, being determined to correspond to the un-drivable area.

Abstract: In an electronic nose apparatus and method based on spectrum analysis, 1) a gaseous sample is dissolved into a solvent in an impinger, and the sample dissolved into the solvent is introduced into an RF resonator, and 2) RF having various absorption spectra according to materials are generated in the RF resonator, and the type of gas is determined through spectrum analysis so that an electronic nose is implemented. In this way, it is possible to overcome the resolution of gas chromatography (GC) and a sensor array and a limited number of multi-channel sensors (the number of channels).

Abstract: There are provided a stereo matching method capable of increasing a resolution and precision of an object and a device for performing the method. The method includes investigating a pattern according to a predetermined period; obtaining left and right stereo images in which the investigated pattern is included or not included; determining whether each of the stereo image obtained according to the predetermined period and a buffering image that is a previous frame image of the stereo image includes the pattern; and generating a final cost volume by performing different image processing according to whether each of the stereo image and the buffering image includes the pattern. Therefore, it is possible to increase precision of a disparity of a thin object and increase accuracy and precision of an object at a long distance.

Abstract: Disclosed is an apparatus and method for calculating a raw-cost necessary for combining images into one image by matching of stereo images. The raw-cost calculation apparatus includes an image acquirer, a window generator, a window mask generator, a window masker, and a raw-cost calculator. In the raw-cost calculation apparatus and method, a raw cost may be calculated by using an adaptive window mask so that accurate 3D information may be obtained on the boundary of thin structures even when stereo images are matched and combined.
