Several national research institutes and companies have studied differently, and there are several approaches in general: 1) measurement mode based on correlation formula photoelectric switch and ccd sensor: the method adopts a correlation type photoelectric switch to measure the length and the height of the vehicle, and uses the ccd arranged on the top of the vehicle to image and measure the width of the vehicle. 2) Measurement mode of the sensor based on full ccd: the method adopts the ccd sensors which separately detect the two sides of the lane to measure the height of the vehicle, and adopts the ccd mounted on the top of the vehicle to measure the length and the width of the vehicle. 3) The method comprises the following steps of (1) positioning the length direction of a vehicle and measuring the length of the vehicle by adopting an infrared light curtain and a line of infrared correlation type photoelectric switches: and (3) carrying out line scanning on the surface of the vehicle by using laser ranging scanners above two sides of the separated driveway to acquire the width and height measurement data of the vehicle.
In order to ensure the accurate and reliable measurement of the vehicle dimension measurement instrument, the sensors of the measurement instruments need to be calibrated. The existing method for tracing the source of the measurement value of the vehicle overall dimension measuring instrument mainly measures the vehicle length, the vehicle width and the vehicle height of a measured vehicle by manually using a steel tape or a laser range finder, takes the measured data as a standard value, measures the vehicle length, the vehicle width and the vehicle height of the same measured vehicle by using the vehicle overall dimension measuring instrument as measured values, and takes the difference between the measured values and the standard value as a measurement error; therefore, a calibration device and a calibration method for a vehicle dimension measurement instrument are needed.
