Utility model content
The utility model is for the deficiency existed in above-mentioned existing apparatus, and provide a kind of structure simple, easy for installation, stable performance, rate accuracy is high and the vehicle length, width and height pick-up unit that the life-span is permanent.
To achieve these goals, the utility model provides a kind of vehicle length, width and height pick-up unit, and this device comprises: the vertical rod of the first rotary scanning type range laser instrument and power supply, the second rotary scanning type range laser instrument and power supply, the 3rd rotary scanning type range laser instrument and power supply, data processing equipment and power supply, fixed laser instrument.
The first described rotary scanning type range laser instrument, the second rotary scanning type range laser instrument are installed on above the vertical rod of road both sides, and range sweep track certain altitude, formed the plane of scanning motion perpendicular to track and vehicle heading, for obtaining width and the altitude information of described vehicle to be measured.
The 3rd described rotary scanning type range laser instrument is installed in the vertical rod of side, track, and the plane of scanning motion is parallel to form an angle with track, for obtaining the length data of vehicle to be measured with vehicle heading.
Optionally, described rotary scanning type range laser instrument is the infrared light sending 905nm, and sweep frequency is 50Hz, and angular resolution is the laser of 0.25 degree;
The scanning distance of described rotary scanning type range laser instrument is 40m, and scanning angle is 0-180 degree.
Described rotary scanning type range laser instrument is connected by network with data processing equipment.
The utility model beneficial effect is as follows:
Pass through the utility model, the wide high data of vehicle at different parts are recorded owing to adopting scanning, and by calculating the displacement information of a certain position of vehicle, obtain the length data of vehicle, technique scheme tool of the present utility model has the following advantages: this system stability is not by the impact of weather; Be easy to installation and maintenance; Vehicle dimension Detection accuracy is high.
Accompanying drawing explanation
The structural representation of a kind of vehicle length, width and height measurement mechanism that Fig. 1 provides for the utility model one embodiment;
Wherein, 1 is the first rotary scanning type range laser instrument, and 2 is the second rotary scanning type range laser instrument, and 3 is the 3rd rotary scanning type range laser instrument, and 4 is data processing equipment.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
Be illustrated in figure 1 a kind of vehicle length, width and height pick-up unit shown in the utility model, the first rotary scanning type range laser instrument 1, first rotary scanning type range laser instrument 2, first rotary scanning type range laser instrument 3 described in the utility model, data processing equipment 4.Described rotary scanning type range laser instrument is fixed in described vertical rod, and the plane of scanning motion of described rotary scanning type range laser instrument is vertical with track, parallel with vehicle heading.
Shown in composition graphs 1, the principle that the vehicle length, width and height that describing the utility model provides detect, when the first rotary scanning type range laser instrument and the second rotary scanning type range laser instrument form vertical scanning face, when detecting that vehicle sails vertical scanning face into, the 3rd rotary scanning type range laser instrument gathers the squiggle in the first moment; When detecting that vehicle rolls vertical scanning face away from, the 3rd rotary scanning type range laser instrument gathers the squiggle in the second moment; Choose in the first squiggle there is step point as unique point, find and the unique point of described first squiggle Corresponding matching in the second squiggle.Described unique point be headstock, the tailstock, compartment concavo-convex, and/or, the delivery position of compartment and headstock.According to the displacement information of the described unique point in described first shape information and described second shape information, obtain the length data of described vehicle to be measured.
Wherein, the time interval in described first moment and described second moment reflects the scan period quantity by first plane of scanning motion of vehicle to be measured.In scan period number, gather the multi-group data in vertical scanning face, calculate the wide high data group of vehicle, leniently select the wide high data of suitable value as vehicle in high data group.
The utility model adopts rotation sweep laser to detect vehicle length, width and height, simple installation, for scanning the waveform obtained, only need the key point displacement finding scanning plane, obtain the length of vehicle, the distance value calculating measurement obtains the wide high data of many groups, and selects the wide height of suitable wide high level as vehicle.In addition, adopt laser range finder, range error is little; For high-frequency rotating laser, within the scope of certain scanning distance, the distance between adjacent analyzing spot is very little, and this just makes the precision recording the speed of a motor vehicle very high.
The above is only the utility model preferred implementation; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
