Abstract

The invention provides a vehicle profile dimensions measuring method, the method comprises the steps: 3D distance measuring data of a measurement area is obtained through a 3D laser distance measuring sensor; a 3D rectangular coordinate system is established to process the 3D distance measuring data of the measurement area, and 3D profile coordinate information of a to-be-measured vehicle in the measurement area is obtained; and according to the 3D profile coordinate information of the to-be-measured vehicle in the measurement area, profile dimensions information of the to-be-measured vehicle in the measurement area is obtained. The invention also provides a vehicle profile dimensions measuring system, the system comprises a distance measurement unit, a first processing unit and a second processing unit. The method can dynamically measure the profile dimensions of the vehicle, and the measurement precision is high; an enforce foundation can be provided for vehicle overloading driving detection, and the method and the system provided by the invention have advantages of real-time capability, reliability, no manual intervention and the like.

Description

technical field [0001] The invention relates to the field of traffic detection, in particular to a method and system for measuring vehicle outline dimensions. Background technique [0002] With the continuous development of the national economy, the construction of expressways and the scale of expressways have achieved unprecedented development, and the automobile industry has also rapidly heated up. At present, all kinds of motor vehicles have become an indispensable means of transportation in the social economy. However, in order to reduce transportation costs, some passenger and freight transport vehicles have been modified to lengthen and heighten the vehicles without authorization, and the phenomenon of overloading and overloading has become increasingly serious. The phenomenon of overloading seriously violates the safety standards for vehicle use, and also shortens the service life of roads and bridges. [0003] At present, most of the vehicle overrun detection, espec...
