Embodiment 1

[0028] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 In the shown embodiment, this vehicle outline dimension measuring device includes a distance measuring instrument 1 connected to a controller 11, a height measuring light curtain and a width measuring light curtain, and the distance measuring instrument 1 is installed on the vehicle 4 to be checked. In the direction of travel, opposite to the reflective plate provided on the inspected vehicle 4, the height measurement light curtain includes a height measurement light curtain transmitter and a height measurement light curtain receiver 2 erected on the measurement channel, and the width measurement light curtain includes a width Measure the light curtain receiver 3 and the width measurement light curtain transmitter 7-1, the width measurement light curtain receiver 3 is arranged above the measurement channel, and the width measurement light curtain transmitter 7-1 is arranged below the road surface of th...

Embodiment 2

[0033] A vehicle profile measurement device, the bearing surface is provided with a cover plate 5, and the cover plate 5 is provided with a gap 6 for the light curtain to pass through. In this embodiment, the width of the gap 6 along the direction of passage is 90 mm; other Features are the same as in Example 1.

[0034] The following is the length measurement data of the Wuling van measured by the rangefinder: the measurement data shows that the maximum error of the length is -20 mm, and the error range is -0.54%~0.28%; the maximum error of the width is 10 mm, and the error range is -0.67% ~0.67%; the maximum error of height is 0 mm, and the error range is -0%~0%.

Abstract

The invention discloses a device and a method for measuring vehicle exterior dimension, which relate to the technical field of measuring. The device comprises a distance measuring device, a height measuring light curtain and a width measuring light curtain which are connected with a controller; the distance measuring device is installed in the travel direction of a vehicle to be inspected, and is opposite to the vehicle to be inspected. The height measuring light curtain comprises an emitter and a receiver, both in vertical arrangement; the width measuring light curtain comprises a width measuring light curtain receiver and a width measuring light curtain emitter, wherein the width measuring light curtain receiver is arranged above the measuring channel while the width measuring light curtain emitter arranged below the road surface of the measuring channel. The light curtain formed by the width measuring light curtain receiver and the width measuring light curtain emitter forms an acute angle with the road surface of the measuring channel. The measuring method measures the exterior dimension of a vehicle such as width, length and height through the use of light curtain and the distance measuring device. Compared with the prior art, the device and the method have small measuring error and save time and labor; free of limitations of the traveling speed of a vehicle, the device and the method achieve high accuracy in measuring the exterior dimension of a vehicle.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a vehicle external dimension measuring device and method for jointly measuring the vehicle external dimension by using a range finder and a light curtain. Background technique [0002] According to the national standard GB7258-2012 "Motor Vehicle Operation Safety Technical Conditions", GB21861-2014 "Motor Vehicle Safety Technical Inspection Items and Methods", GB 1589-2004 "Road Vehicle Outline Dimensions, Axle Load and Quality Limits", in order to Check at the source, all public security vehicle management offices and motor vehicle inspection stations must conduct mandatory inspections on the outer dimensions of newly registered vehicles and in-use motor vehicles that exceed the limit; It is necessary to detect various vehicle outline dimensions that exceed the limit. [0003] At present, the detection of vehicle outline dimensions basically still uses manual measurement me...
