SYSTEM AND METHOD FOR MONITERING RADIATION BASED ON IMAGING

摘要

The present invention relates to imaging based radiation monitoring systems and methods. An imaging-based radiation monitoring system according to the present invention comprises a camera module for photographing an optical image; A radiation detection module for detecting radiation; A motion extraction unit for extracting a motion of the object from the optical image photographed by the camera module and extracting the position of the object in a predetermined reference frame unit; A radiation signal acquiring unit for acquiring a radiation signal at a position corresponding to a position of the object at the photographing time, the radiation signal being synchronized with a photographing time of each of the reference frames in a radiation signal detected by the radiation detecting module; And a controller for accumulating the radiation signals acquired for each of the reference frames by the radiation signal acquisition unit and calculating the cumulative radiation for the object. Accordingly, it is possible to track the movement of a moving object such as a vehicle through an optical image, extract radiation from a position corresponding to the position of the object in each frame of the optical image in the radiation signal, and accumulate the radiation, The signal-to-noise ratio can be improved and the monitoring can be performed without restriction of movement of the object.
