Abstract: A method for object recognition recognizing an object included in an image comprises extracting image features from the image; extracting a first candidate object matched to each of the image features with the highest similarity score from among objects within an object database which previously stores information about a target object for recognition; extracting a second candidate object based on a first matching score of the first candidate object; and based on a second matching score of the second candidate object calculated by matching features of the second candidate object and the image features, recognizing whether the second candidate object is the target object included in the image.

Abstract: Provided are an urban digital twin platform system and a moving object information analysis and management method therefor. Through the urban digital twin platform system and the moving object information analysis and management method, a moving object such as a vehicle or a pedestrian may be detected from multimodal sensor data, data on the moving object may be generated, and a situation may be quickly determined by deriving complex actions of the moving object. The urban digital twin platform system includes a multimodal sensor data input and objectification module configured to detect a moving object and to generate objectification data, a multimodal sensor data analysis module configured to classify basic actions of the moving object, to classify complex actions of the moving object, and to generate moving object information, and an urban space data server configured to store the objectification data and the moving object information.

Abstract: Provided are a system and a method for tracking a position based on multi sensors. The system according to the present invention includes: a space management server which divides a predetermined space into a predetermined number of spaces to generate a plurality of zones and manages information of each zone; and a zone management server which manages the information of the zone generated by the space management server and provides the space management server with zone session information of an object positioned in each zone and positional information of the corresponding object sensed by a position tracking sensor every time slot.
