PURPOSE: A method and device for mapping an artificial mark and a method and device for measuring the position of a moving body using the same are provided to measure the position of the moving body by using a coordinate value of an artificial mark stored in a map information DB and the relative position information of the artificial mark. CONSTITUTION: An environment information obtaining unit measures the position information of surrounding objects with an artificial mark and the position information of the moving body. An artificial mark detector(106) obtains the image of the artificial mark. An artificial mark detecting block(110) calculates the relative position information of the artificial mark by analyzing the obtained image, the position information of the surrounding objects, and the position information of the moving body. A mapping unit(114) calculates the coordinate of the artificial mark by using the relative position information and stores the coordinate and the ID of the artificial mark in a database(116) as map information.

CONSTITUTION: A communication module(102) implements the wireless telecommunication with a parking management apparatus. A driver(106) moves an image capturing unit(108) with a rail installed inside the parking lot. The capturing unit photographs the inside of the parking lot inside. The photographed image is transferred. A distance sensor(110) senses a distance with respect to the inside of the parking lot.

PURPOSE: A method and a device for generating a safe route of a mobile robot are provided to minimize a collision with obstacles by assuring a safe distance. CONSTITUTION: A method for generating a safe route of a mobile robot is as follows. A route from a starting place to a destination is searched in the map information input in a robot(200). When the robot is moved along the searched route, estimated distance information between the robot and obstacles is extracted(202). The route is regionally corrected using the extracted estimated distance information(204).

PURPOSE: A remote monitoring system and a method are provided to monitor a monitoring area at remote control in real time by visualizing a failure in three dimensional. CONSTITUTION: At least one monitoring units(110a,110b,110c) are installed at the inside or the outside same monitoring area or different monitoring area. The monitor is classified as an identifier. The identifier comprises the name and the type information of the monitor. The monitor transmits the monitoring information of the monitoring target area. A remote monitoring server(120) receives a three-dimensional model of the monitoring target area in advance. The remote monitoring server receives the monitoring information from the monitor.

본 발명은 자율이동로봇의 자율주행을 위한 지도 생성에 관한 것이다. 즉, 본 발명에서는 실내 환경에 대한 물리적 치수가 도시되어 있는 도면을 통해 자율이동로봇에 주행기술에 사용하기에 적합한 격자지도를 저비용으로 정확하게 획득함으로써, 종래에 사람이 직접 물리적 수치를 측정하여 지도를 작성하는 것 보다 소요되는 시간을 줄여 저비용으로 격자지도 작성이 가능하다. 또한, 종래에 자율이동로봇에 장착되어 있는 거리측정 센서와 인코더 정보를 활용하여 지도를 작성하는 방법은 실내구조가 복잡할수록 지도를 작성하지 못 하거나 잘못된 지도를 획득할 가능성이 높았으나, 본 발명에서는 도면을 기반으로 격자지도를 작성하기에 복잡한 실내 환경에서도 정확한 지도를 획득할 수 있다. 자율이동, 로봇, 격자, 지도, 벡터, 이미지

Abstract:
An optical vision chip and an image recognition method using the same are provided to perform an image recognition operation while not requiring complex mathematical equations or calculation by directly comparing an object image with a standard model image. An optical vision chip includes the first display element(10), the second display element(14), and an optical sensor(18). A size and a shape of the first pixel(12) of the first display element and the second pixel(16) of the second display element are overlapped with those of a sensor pixel of the optical sensor. The first display element displays an object image, and the second display element displays a standard model image stored at an external memory. When the second display element displays the standard model image, the brightness of the standard model image is a complement to the brightness of the object image. The optical sensor outputs an electric signal, which expresses an optical difference between the object image and the standard model image, via an electrode line. If the electric signal outputted by the optical sensor is sent to an external display unit, an optical difference of the image can be displayed.
