Description
Technical field
The utility model relates to and a kind ofly obtains the measurement mechanism of contour of the vehicle overall size based on Flame Image Process, particularly a kind of vehicle dimension is carried out the device that automatic gauging is measured.
Background technology
Along with social economy develops rapidly, the rapid growth of driving automobile industry becomes one of requisite vehicles of present society as motor vehicles such as automobiles.Yet part is used for the vehicle user of goods/passenger traffic purposes in order to obtain bigger economic interests, by reequiping vehicle dimension to increase the vehicle volume, reach the purpose that increases the disposable freight volume of vehicle, reduce transportation cost, yet the safety standard that vehicle uses has seriously been violated in this behave.The annual traffic hazard act that takes place because of overload of vehicle is unequal to number, the especially vehicle of widening.So the security for support vehicles, vehicle all must carry out annual test every year, but carry out in the manual measurement mode often when detecting the size of vehicle at present, this metering system efficient is extremely low, the personnel cost height, because of being subjected to the restriction of survey instrument, very inconvenient during to the measuring vehicle height, accuracy of measurement and violation operation were difficult to control when oversize vehicle was carried out vehicle.
In order to address the above problem, the device that has also occurred some measuring vehicle sizes in recent years, as laser 3 d scanner, the laser scanning instrument of this employing laser triangulation principle has very big advantage owing to can directly obtain the three-dimensional space data of measured target and obtain image information simultaneously in the application of obtaining complex-curved data; But there is following shortcoming in it: 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 the limit and the angle information of subject, also is inaccurate if having, and it is bigger 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 has to have again such as instruments such as laser range finder, infrared ambulators that influenced by weather, light bigger the unsettled defective of acquired signal.
Moreover above-mentioned vehicle arrangement can't be applied to indoor measurement, because that measured target is in is indoor, and the size span scope is very big, vehicle length especially, and buggy is about 4 meters, and general lorry is about 10-16 rice, and truck is about 21 meters.If can not testee all be in the formed measurement field of camera reasonable disposition measurement camera, just can not intactly measure the length and width high parameter of tested vehicle.
The utility model content
The purpose of this utility model is to overcome the problems referred to above, and a kind of indoor and outdoors that is applicable to is provided, and detection efficiency, precision height, the measuring process all automatic measurement vehicle dimension is carried out the device that automatic gauging is measured.
For reaching the purpose of foregoing invention, the technical scheme that is adopted is: a kind of device that vehicle dimension is carried out the automatic gauging measurement, comprise computing machine and the measurement mechanism that is connected with this computing machine by data cable or radio transmission apparatus, described measurement mechanism comprises that described imaging device is arranged on the column of support in order to two groups of two dimensional laser scanning instrument of measuring vehicle height and subsidiary vehicle length and width and imaging device; Wherein two dimensional laser scanning instrument symmetry week schedules on the crossbeam or is directly fixed on the indoor roof of buildings, or be symmetrically fixed on junction between crossbeam and the column, or directly symmetry is mounted on corner between indoor roof of buildings and the side wall.Support during practical operation can be any one in portal frame or the L type support, also can workshop wall column etc. do be equal to alternative.
One end of described column is fixed on measuring table or the ground.
Described imaging device mainly by casing, case lid, be arranged at guide rail in the casing and two or more camera or video camera and connect and compose, one side of described casing offers the imaging window, and described camera or video camera are connected and fixed on the guide rail by pedestal.
The pedestal that is positioned at camera or video camera both sides is provided with two arc regulating tanks of adjusting base angle, regulates clamping screw and penetrates this arc regulating tank and place the interior grip block of guide rail to be connected, and pedestal is locked on guide rail.
Also comprise the lighting device that is arranged on support, roof or the body of wall.
Described radio transmission apparatus is any one among GPRS, CDMA or the WiFi.
Basic functional principle of the present utility model is: adopt the virtual coil technology, promptly in the camera imaging scope, by software virtual one measured zone, when large-scale dynamic object (vehicle) enters this zone, measuring system starts automatically, this moment, camera began to take measurement, and the imaging device that is distributed in vehicle roof and side successively obtains the photo of vehicle.Survey wide mechanism according to the surface mark situation that is blocked, obtain the marginal date of vehicle one side (left side or right any side) from the headstock to the tailstock; The marginal date of the other side of vehicle from the headstock to the tailstock obtained in two groups of two dimensional laser scanning instrument scannings, and two groups of data are obtained vehicle width by computational analysis; The height of car data are obtained in the scanning of two dimensional laser scanning instrument scanning simultaneously, analyze height value, draw real-time vehicle profile height; When vehicle rolls measurement range away from, provide the wideest, the mxm. of vehicle; Gauging machine structure (also can survey wheelbase) was preserved the continuous side synthetic complete vehicle side of photo intelligence and was resembled this moment, calculated headstock to tailstock longest dimension; Thereby comprehensively finish length height, width, length coordinate calculating.When not having large-scale dynamic object in the measured zone, system thinks that vehicle has sailed out of measurement range fully, measures and finishes.Software system analysis calculates the size of vehicle length.
In sum, the utlity model has following advantage: vehicle can not stop, and can finish measurement automatically by measured zone; Do not contact tested vehicle, detection efficiency height, tested vehicle do not need to stop to be measured, and whole testing process is no more than 1 minute; The accuracy of detection height, its measuring error＜1%; Applicability is strong, applicable to indoor and outdoors.The utility model utilizes common laser scanner measurement height of car, and auxiliary simultaneously imaging device calculates the length and the width of vehicle, reduces the hardware input of part imaging device, reduces cost.
