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 full-automatic device that obtains image measurement vehicle contour dimension according to vehicle in the motion.
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 obtain the full-automatic device of image measurement vehicle contour dimension according to vehicle in the motion.
For reaching the purpose of foregoing invention, the technical scheme that is adopted is: a kind of full-automatic device that obtains image measurement vehicle contour dimension according to vehicle in the motion, comprise computing machine and the measurement mechanism that is connected with this computing machine by data cable or radio transmission apparatus, described measurement mechanism is mainly by measurement bracket, two groups or more width measure camera and highly measure camera, and two groups of optoelectronic switches constitute, wherein measurement bracket is placed on measuring table or the ground, described width measure camera is installed on the crossbeam of measurement bracket upper end, highly measure on the vertical pillar that camera is installed on the measurement bracket both sides, two groups of optoelectronic switches are installed on the both sides of vertical pillar respectively.
Described each group width measure camera and highly to measure camera all be to be made of two or more cameras.
Described measurement bracket is an arch support, or is oppositely arranged formation by " L " shape support of two handstand.
Also comprise the lighting device that is arranged at both sides, measurement bracket upper end.
Described radio transmission apparatus is any one among GPRS, CDMA or the WiFi.。
Basic functional principle of the present utility model is: when vehicle enters measurement range through measurement bay, trigger the signal of optoelectronic switch, this moment, camera began to take measurement, the camera that is distributed in vehicle periphery is successively taken pictures to the vehicle cross section, captured photo, seamless spliced one-tenth three sub-pictures, form three sides of vehicle, Flame Image Process, analysis and measurement are carried out in three measurements, survey wide camera according to the surface mark situation that is blocked, analyze the width value of the right and left, draw real-time vehicle section width then; Survey high camera according to the facade sign situation that is blocked, analyze height value, draw real-time vehicle profile height; Surveying appearance machine (also can survey wheelbase) takes and the storage sequence image; Thereby comprehensively finish length height, width, length coordinate calculating; When vehicle rolls measurement range away from, provide the wideest, the mxm. of vehicle, the image of appearance machine is surveyed in splicing simultaneously, and analyzes longest dimension.
In sum, the utlity model has following advantage: 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 precision＜0.5%; Applicability is strong, applicable to indoor and outdoors.
