Embodiment

[0066] like picture 1 As shown, the system of the embodiment of the present invention is composed of six parts: the measuring host 7, the triggering and starting units 1 and 2, the height measuring laser light curtain 3, the height measuring diffuse reflection target plate 5, the height measuring camera assembly 6, and the gantry 4. The trigger start unit described above is composed of a measurement trigger transmitting unit 1 and a trigger receiving unit 2 . The height measurement unit of the vehicle is composed of a height measurement laser light curtain 3 , a height measurement diffuse reflection target plate 5 and a height measurement camera assembly 6 .

[0067] The laser light curtain 3 and the height-measuring diffuse reflection target plate 5 are installed on both sides of the gantry 4 respectively, and the distance between them is Y1=5m. The laser light curtain 3 is Z2=1m away from the ground, and the laser wavelength used is 780nm. A band-pass narrow-band filter...

Abstract

The invention discloses a vehicle height measurement system and method. The system comprises a portal frame (4). The vehicle height measurement system also comprises a laser light screen (3), a diffuse reflection target (5), a shooting assembly (6) and an information processing unit. The laser light screen (3) and the diffuse reflection target (5) are arranged to vertical rods at the two sides of the portal frame (4) respectively. The laser light screen (3) is used for emitting a line of laser beams to the height measurement diffuse reflection target (5), and thus a line of laser spots are formed on the diffuse reflection target (5); the shooting assembly is used for recording laser spots on the diffuse reflection target (5) under two conditions that a vehicle passes through the portal frame or no vehicle passes through the portal frame respectively; and the information processing unit is used for calculating the height of the passing vehicle according to the stored laser spot data obtained when no vehicle passes through the portal frame and the laser spot data obtained when the vehicle passes through the portal frame.

Description

technical field [0001] The invention relates to a vehicle height measurement device, in particular to a vehicle height measurement system and method. Background technique [0002] In recent years, the overloading of vehicles has seriously affected nation The safety of property and people's lives endangers the social and economic order and has become a prominent social problem. At present, the detection of the size of the vehicle is often carried out by manual measurement, which has the following problems: 1. The measurement accuracy and illegal operations are difficult to control. 2. The degree of automation is low, which cannot meet the development needs of the motor vehicle management department for information management of motorized vehicles. [0003] The publication number of the patent application is CN102620662, which provides "automatic vehicle size measurement system and its measurement method based on light curtain". and other shortcomings. Contents of the inv...
