FMCW Augmented reality military training system based on position recognition using FMCW radar equipped on ship

摘要

The present invention relates to an augmented reality military training system based on location recognition using an FMCW radar on a ship, and more particularly, by utilizing radar and sensors to identify the internal path of the space to be trained and the location of each crew. It relates to an augmented reality military training system based on location recognition using an FMCW radar in a ship that can escape to the outside through an emergency situation in the ship. Using the optical flow of image data input through the camera facing the user's line of sight, an optical flow processing unit, an ultrasonic sensor, and an IMU sensor that obtain the first displacement value according to the position change and rotation change of the camera's central axis facing the front. A sensor processing unit capable of obtaining a second movement displacement value according to a rotation change of the central axis of the camera facing the front of the user using a sensor value input through the first movement displacement value, and the first movement displacement value of the optical flow processing unit and the sensor processing unit. 2 A movement displacement correction unit that compares movement displacement values and corrects the position movement displacement of the central axis of the camera, and a PDR that understands movement information such as a person’s movement speed, acceleration, direction, and distance through the PDR and calculates the position movement of the object to be positioned. By controlling the components below the FMCW radar unit and FMCW radar unit, which detects the space by detecting the space through space detection scanning by the positioning unit and the FMCW radar, check the internal path in the training space using the FMCW radar and people It stores the user's movement information and training space data through the control unit, movement displacement correction unit, PDR positioning unit and FMCW radar unit, which perform a series of processing related to the training system to identify the location of the vehicle and escape to the outside. Training information according to the user's movement information and a database storing design data or electronic maps for the internal structure of the training space, and the position movement displacement corrected through the movement displacement correction unit are provided through the network and can be monitored. It includes a display unit that matches the training space data provided through the positioning unit and the FMCW radar unit and outputs an image of the internal path of the training space and the location of a person. When the beams of the FMCW radar are radiated in the training space, a plurality of beams are installed so that all of the beams are included in the space, and the FMCW radar operates from a direction close to the user's location, so that the training space path according to the user's movement can be identified. .
