Calibrating device and method of vehicle profile dimension automatic measuring apparatus

Abstract

The invention relates to a calibrating device and method of a vehicle profile dimension automatic measuring apparatus, and belongs to the vehicle measuring technical field; the calibration method comprises the following steps: allowing the calibrating device to use an industrial control computer to control a mobile dolly to travel, wherein the mobile dolly is configured with a calibrating plate rotating device; using a laser radar of the vehicle profile dimension automatic measuring apparatus to measure the horizontal distance between the radar and the calibrating plate; using a computer calibrating program to verify the distance measured by the laser radar and the mobile dolly travel displacement; and evaluating the vehicle profile dimension automatic measuring apparatus accuracy. The calibrating device comprises the mobile dolly configured with the calibrating plate rotating device, a customization guide rail, a drive unit, a slave unit, a telescopic scale and the industrial control computer; the calibrating device and method can accurately evaluate the measuring precision of the vehicle profile dimension automatic measuring apparatus measuring the vehicle length, width and height, and can evaluate a laser radar mounting position deviation and angle deviation, thus correcting the whole measuring apparatus. The calibrating method and device are high in detection precision, strong in practicality, and have very well practical values and promotion prospects.

Description

technical field [0001] The device of the invention belongs to detection equipment in the technical field of vehicle measurement, and in particular relates to a calibration device and method for an automatic measurement device for vehicle outline dimensions. Use the industrial control computer to control the movement of the mobile trolley equipped with the calibration plate rotation device. The laser radar measures the horizontal distance between it and the calibration plate of the mobile trolley. The computer calibration device verifies the distance measured by the laser radar and the movement of the calibration plate rotation device. The traveling displacement of the trolley is used to evaluate the accuracy of the non-contact automatic measuring device for the outer dimension of the vehicle. The device has the characteristics of high detection accuracy and strong repeatability, fast verification speed, novel and unique design concept, and provides a reliable basis for the cor...
