Abstract: Provided are road object recognition method and apparatus using a stereo camera, and the road object recognition method using a stereo camera includes a road image acquisition step of acquiring a road image by using the stereo camera, a road surface recognition and separation step of recognizing a road surface from the acquired road image and separating the road surface, and a road object recognition step of recognizing a road object from the separated road surface. According to the road object recognition method and apparatus using the stereo camera, in a state in which a front traveling vehicle is included, a road surface is recognized from a road image acquired using the stereo camera and is separated, so that it is possible to effectively recognize objects on the recognized road surface.

Abstract: A calibration and rectification method includes arranging a monitor vertically relative to the optical axis of the stereo camera; displaying 3D patterns, similar to patterns obtained by projecting pattern images of various postures produced by a panel virtually located in front of the stereo camera, onto the monitor through a 3D graphical technique; and the stereo camera acquiring the 3D patterns displayed on the monitor to perform calibration and rectification, thereby correcting images of the stereo camera.

Abstract: Disclosed is a method and device for collecting particulate contaminants removed using a CO2 decontamination medium from an early step of a decontamination process. The device removes particulate contaminants from a contaminated subject by a decontamination stream, and simultaneously forms another stream for collecting such contaminants into a collecting filter, thus preventing such contaminants from diffusing into the atmosphere. The device forms streams between the nozzles and the surface of the contaminated subject to readily move the nozzles along the surface of the subject without frictional resistance, to reduce the sense of fatigue of the operator.

Abstract: The present invention relates to a radioactive electron emitting microchannel plate. More particularly, to a radioactive electron generating microchannel plate comprising (a) a pair of parallel substrates; (b) at least one radioactive material layer deposited on an inner surface of the substrates; and (c) at least one electron ray-amplifying layer deposited on the surface of the radioactive material layer. The emitted electron ray is amplified by penetrating into the cavity formed by a pair of parallel substrates and is further amplified by reflecting from the electron ray-amplifying layer. As the substrate in the microchannel plate, use can be made of a capillary tube or a thin plate. The microchannel plate of the present invention can be applied as an electron ray source in an electron ray-generating device, an image display device, and electron ray-etching device.

Abstract: Disclosed is a fiber bundle contactor in which fibers are packed in high density within a column. When two liquid phases flowing in parallel, one of which contains the desired components, are contacted with the entryway of the highly packed fiber bundle, the two liquid phases are very thinly dispersed among gaps around the respective fibers by capillary action induced by the clearance between the fibers. By means of this capillary action, the two liquid phases are maintained as a continuous stream, and the two phases are brought into very intimate contact, thereby ensuring a very large surface area for liquid-liquid extraction to proceed.
