Embodiment Construction

[0031] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0032] An embodiment of the present invention provides a vehicle size measuring device, and the vehicle size measuring device provided by the embodiment of the present invention will be introduced below.

[0033] figure 1 is a structural block diagram of a vehicle size measuring device according to an embodiment of the present invention.

[0034] Such as figure 1 As shown, the vehicle size measuring device includes a first measuring unit 11 and a second measuring unit 12 .

[0035] The first measuring unit 11 is used to scan a plane perpendicular to the driving direction of the vehicle by laser radar to measure the width and height of the vehicle.

[0036] The second measuring unit 12 is us...

Abstract

The invention discloses a vehicle size measurement method and a device. The vehicle size measurement method comprises scanning a plane vertical to the running direction of a vehicle by a laser radar to measure the width and the height of the vehicle; and scanning a plane parallel to running direction of the vehicle and vertical to the horizontal plane by the laser radar to measure the length of the vehicle. According to the vehicle size measurement method and device provided by the invention, the critical positions in the three dimensions of length, width and height of the vehicle can be measured by the laser radar, and the vehicle size can be calculated by reducing the critical positions on both ends in each dimension. Accordingly, the problem in quickly and accurately measuring the vehicle size is solved, thereby realizing quick and accurate measurement.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a method and device for measuring vehicle dimensions. Background technique [0002] In the prior art, the dynamic overload and limit detection equipment of each toll station can only detect the axle load quality, but cannot identify some geometric parameters of the vehicle, such as the size of the vehicle. These geometric parameters are important for traffic safety and effective control of overrun operations. has important meaning. Some toll stations directly use a tape measure to carry out contact measurement of the vehicle. This method of measurement has low measurement accuracy, poor measurement efficiency and increases the workload and labor hours of the operator. [0003] It is particularly important in today's transportation industry to realize fast and accurate measurement of road vehicle overrun detection. But there is currently no universally accepted easy method. [0004] ...
