APPARATUS FOR MEASURING LENGTH OF QUEUED VEHICLES, METHOD FOR MEASURING LENGTH OF QUEUED VEHICLES, AND COMPUTER READABLE RECORDING MEDIUM HAVING COMPUTER PROGRAM FOR MEASURING LENGTH OF QUEUED VEHICLES

摘要

The present invention is not using the camera to take a special vehicle and the vehicle in the rear, rather, a vehicle heat shield to provide a length measuring device that can measure the length of the column for the purpose. Heat shield length measuring device (1), opposite to the front of the vehicle within the predetermined detection range of the vehicle based on the detection signal acquired from the sensor installed in the sensor (2), to obtain the position and speed of the vehicle is detected vehicle detection unit (21) and, of the vehicle is detected, the closest approach to the sensor jungyimyeo from a change in the position and speed of the first vehicle is driving, the first stop estimating a stop position of the vehicle position estimating section 24, the estimated stop position by estimating the inter-vehicle distance maze than last column as a vehicle to stop being a location close to the sensor, the heat shield to obtain the vehicle being stopped length of the string length includes the estimator (25). ;
