Abstract: PURPOSE: An object detecting device using a 3D image and a method thereof are provided to shorten object detection time by detecting an object according to a size change of the object by using distance information of the object. CONSTITUTION: An image processing unit(120) generates an image pyramid about a 2D image of an object obtained from an image obtaining unit(110), divides a 3D image obtained from the image obtaining unit into one or more object candidate areas by using distance information, and estimates an object size of each object candidate area.

Abstract: PURPOSE: An altitude measuring device and using a barometric altimeter and GNSS(Global Navigation Satellite System) and a method thereof are provided to precisely measure an altitude for a location by using a barometric altitude variation received from a barometric altimeter along with a satellite altitude value. CONSTITUTION: An altitude measuring device(200) includes an interface(201), a processor(203), and a database(205). The interface receives a satellite altitude value from GNSS and a barometric altitude variation for a barometric altitude value from a barometric altimeter respectively at pre-set time intervals, in relation to a specific location, and stores in the database. The interface additionally receives VDOP(Vertical Dilution of Precision) corresponding to the satellite altitude value from GNSS, and stores in the database. If a satellite altitude variation for the satellite altitude value exceeds a pre-set variation, or a confidence value for the satellite altitude value does not satisfy a pre-set confidence value, the processor measures the altitude for the specific location by using the satellite altitude value and the barometric altitude variation. The processor acquires the satellite altitude value and the barometric altitude variation from the database. The database stores the satellite altitude value and the barometric altitude variation for the barometric altitude value. [Reference numerals] (201) Interface; (203) Processor; (205) Database

Abstract: A scheduling method for processing data of mobile Internet communication is provided to reduce overhead of a MAP such that users cannot recognize the map. The total number of users is recognized by using a pilot signal(S1). It is checked whether it is an overload state according to the recognized number of users(S2). In case of an overload state, it is checked whether a user to be currently processed is an existing connector or a newly connected user(S4). If the user is a newly connected user, the corresponding user is preferentially processed(S3). If the user is an existing user, the user is on standby in a buffer and gives a priority level to the user according to a priority contention algorithm(S5). It is checked whether or not a user coming from the buffer has a high priority level(S6).
