Abstract

Disclosed is an apparatus for dynamic measurement of vehicle outer contour dimension and weight, comprising a computer and measuring apparatuses connected with the computer via transmission devices, wherein the measuring apparatuses comprise a support and an imaging apparatus. The measuring apparatuses further comprise an axle loading instrument installed upon a measuring platform or ground and a length-measuring laser scanner which is arranged at the middle position of the cross beam of the support or directly fixed to the internal roof of the building and used for measuring the length of the vehicles, and a height-measuring laser scanner which is installed at the joint section of the cross beam and the column. The imaging apparatus is arranged at the other end of the cross beam which is provided with the height-measuring laser scanner. The apparatus of the utility model employs two laser scanners and an imaging apparatus to jointly complete the outer contour dimensional measurement of a vehicle moving at low speed. The apparatus features high detecting precision, with the detecting error no greater than 0.5% and the calculating time no longer than 5s. The axle loading instrument installed to the apparatus allows the detection of the vehicle weight while the laser scanners measure the outer contour of the vehicles, thereby raising the detecting precision.

Description

The device of a kind of kinetic measurement vehicle outer profile size and weight

Technical field

The utility model relates to the vehicle field of measuring technique, relates in particular to the measurement mechanism that the departments such as a kind of motor vehicle inspection station and road vehicle overrun and overload measuring station are used for measuring vehicle contour dimension and weight.

Background technology

The motor vehicle overrun and overload has become and has had a strong impact on the country and people's security of the lives and property, jeopardizes a stable outstanding problem of social economic order.For reaching the overload transportation purpose, must carry out various repackings to motor vehicle, as motor vehicle is added steel plate, strengthen compartment size etc.So forbid the motor vehicle that transfinites from the source, it is very necessary in departments such as motor vehicle inspection station and highway overload overload measuring stations superelevation, super wide, overlength, overweight motor vehicle to be carried out detection of dynamic.According to standard GB/T 1589-2004 " road automobile contour dimension, axle load and quality limit value ", GB7258-2004 " motor vehicle safe and technical specification ", each motor vehicle inspection station must carry out compulsory test to the new registration motor vehicle with in the contour dimension with motor vehicle; Highway department also needs various motor vehicle contour dimensions are detected in overload control transfinites administrative law enforcement.In present testing process, there is not preferably kinetic measurement motor vehicle contour dimension device, basically still adopt over the manual measurement mode, because manual measurement uncertain and waste time and energy dangerous, in the urgent need to a kind of surveying instrument motor vehicle contour dimension is measured automatically, to reduce the interference of surveying work intensity and human factor.

Many devices that are used for measuring vehicle contour dimension have also appearred in recent years, although it has very large advantage when obtaining complicated overall size, but have following shortcoming: 1, hardware cost is very high, and middle general 30 ~ 400,000 apart from camera, the price of low coverage camera is higher; 2, the some cloud can't show limit and the angle information of subject, also is inaccurate if having, and it is larger to run into on-right angle and non-straight flange error; 3, subject the darkest and highlights branch cloud disappearance can't obtain complete image.Also have instruments such as laser range finder, infrared ambulator to exist again affected by weather, light larger, the unsettled defective of collection signal.4, when measuring outline, can not finish simultaneously the measurement of vehicle weight, need survey and sail weight-measuring device into after the contour dimension weight is measured, increase detection time.

The utility model content

For above-mentioned deficiency of the prior art, the utility model provides a kind of contour dimension of low speed (5-10Km/h) moving vehicle and measurement mechanism of weight measured simultaneously, and it has, and production cost is low, the measuring accuracy advantages of higher.

In order to reach the foregoing invention purpose, the technical solution adopted in the utility model is for providing the device of a kind of kinetic measurement vehicle outer profile size and weight, comprise computing machine and the measurement mechanism that is connected with computing machine by transmission equipment, described measurement mechanism comprises support and imaging device, and described measurement mechanism comprises that also being installed in measuring table or ground axle load meter and one is arranged on the crossbeam centre position of support or is directly fixed on the long laser scanner of survey that is used for measuring vehicle length on the Indoor environment roof; The high laser scanner of survey that is installed in crossbeam and column junction; Described imaging device is arranged on the other end that root crossbeam of surveying high laser scanner is installed.

Further, described imaging device is camera or video camera.

Further, be equipped with on the support of surveying high laser scanner and also be provided with lighting device.

The beneficial effects of the utility model are: the device of this kinetic measurement vehicle outer profile size and weight adopts two laser scanners and imaging device jointly to finish the measurement of the outer profile size of low-speed motion vehicle, its accuracy of detection is high, detection error≤1%, meter evaluation time≤5s; The axle load meter that this device arranges can be measured the weight of vehicle simultaneously at the outline of laser scanner measurement vehicle, has improved detection efficiency.
