Problems solved by technology

[0003] The technical solution of measuring the appearance of vehicles through imaging technology is expensive and will be affected by light, such as fog and haze, which will affect the imaging effect
The technical solution using all light curtain sensors can only be used for the measurement of vehicles with regular appearance, and for vehicles with irregular appearance similar to large construction machinery, the technical solution using all light curtain sensors cannot meet the measurement requirements
The vehicle size measurement technical solutions in the prior art are mainly aimed at passenger cars or trucks, and the measured parameters are not consistent with the requirements of special measurement. Therefore, it is necessary to develop a technical solution for measuring the size of special vehicles

Embodiment Construction

[0025] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0026] In order to detect the size of the vehicle, such as the length, width, height, wheelbase and the like of the vehicle, the present invention mainly adopts a light curtain sensor and a displacement sensor (such as a laser displacement sensor or an ultrasonic displacement sensor, and the laser displacement sensor or for illustration) as a signal sensing device. Two light curtain sensors can form a group of light curtain sensors, one light curtain sensor acts as a transmitter, and the other light curtain sensor acts as a receiver. Each group of light curtain sensors has multiple sensing points. The sensing points that emit infrared rays and the sensing point...

Abstract

The invention discloses a vehicle size detection method and device. The vehicle size detection device comprises a signal collection system, a signal processing system and at least one selected from a height measuring system, a width measuring system, a length measuring system and a wheelbase measuring system, wherein signal collection system collects signals output by at least one of the height measuring system, the width measuring system, the length measuring system and the wheelbase measuring system, and sends the signals to the signal processing system; the signal processing system outputs height, width, length or wheelbase signals according to the received signals; and the height measuring system comprises at least one pair of induction points which is arranged at preset height of at least one group of light screen sensors, and the height signals are analog signals. The cost of the size detection device for special vehicles is reduced, and parameters including the height, width, length and wheelbase of the vehicle can be accurately detected.

Description

technical field [0001] The invention relates to the field of vehicle detection, in particular to a vehicle size detection method and equipment. Background technique [0002] The measurement of vehicle size is an important operation to verify whether the vehicle meets the design goals, and it is also an important operation for the traffic management department to detect whether the size of vehicles driving on the road meets the requirements of relevant laws and regulations. For assembly line operation, it is not suitable to manually measure each vehicle, so different vehicle detection systems have also been developed in the prior art. For example, the appearance of the vehicle is imaged by a two-dimensional laser scanner, and then the size of the vehicle is obtained according to the technical means of image processing, or a large number of light curtain sensors are arranged to measure the length, height, width, pose and other parameters of the vehicle. [0003] The technical...
