METHOD AND SYSTEM FOR IDENTIFYING MOVING OBJECT, AND METHOD AND SYSTEM FOR INSPECTING MOVING OBJECT BY RADIATION IMAGING

摘要

DISCLOSED IS A METHOD FOR INSPECTING A MOVING OBJECT BY RADIATION IMAGING (1A), COMPRISING: A DRIVING-IN STEP OF MOVING A MOVING OBJECT (1A) INTO A PASSAGE (14), A RUNNING DIRECTION JUDGING STEP OF JUDGING A RUNNING DIRECTION OF THE MOVING OBJECT (1A), A VELOCITY MEASURING STEP OF MEASURING A MOVING VELOCITY OF THE MOVING OBJECT (1A), A LIGHT BEAM EMITTING STEP OF EMITTING LIGHT BEAMS FROM ONE SIDE OF THE PASSAGE (14), A LIGHT BEAM RECEIVING STEP OF RECEIVING THE LIGHT BEAMS NOT SHIELDED BY THE MOVING OBJECT (1A) AT OTHER SIDE OF THE PASSAGE (14), A PROFILE DETERMINING STEP OF DETERMINING A PROFILE OF AT LEAST ONE PORTION OF THE MOVING OBJECT (1A) BASED ON THE RECEIVED LIGHT BEAMS AND THE MEASURED MOVING VELOCITY OF THE MOVING OBJECT (1A), AN IDENTIFYING STEP OF DETERMINING TYPE OF THE MOVING OBJECT (1A) BY COMPARING THE PROFILE OF THE AT LEAST ONE PORTION OF THE MOVING OBJECT (1A) WITH INFORMATION OF MOVING OBJECTS STORED PREVIOUSLY, AND AN INSPECTING STEP OF DETERMINING WHETHER OR NOT THE MOVING OBJECT IS TO BE INSPECTED BY RADIATION IMAGING AND DETERMINING A METHOD IN WHICH THE MOVING OBJECT (1A) IS TO BE INSPECTED BY THE RADIATION IMAGING BASED ON THE IDENTIFIED TYPE OF THE MOVING OBJECT (1A). THE METHOD AND THE SYSTEM ACCORDING TO THE PRESENT INVENTION CAN ADOPT CORRESPONDING SCANNING CONTROLLING MANNERS FOR DIFFERENT VEHICLES, SO THAT INSPECTION INFORMATION OF INSPECTED VEHICLES IS COMPLETE, INSPECTION IMAGES ARE OF HIGH QUALITY, AND RADIATION DOSE RECEIVED BY DRIVERS ARE MINIMAL.
