A kind of fleet vehicles outline data acquisition method based on laser scanner technique, comprising:
The width and height of the fleet vehicles of bicycle road or multilane are acquired, the high data of width are formed；
It is acquiring width and is acquiring the length of the fleet vehicles, formation length data while height or later；
The high data of current width are judged, if the current high data of width are continuously detected, merge length, width and height data；If current
The high data of width are not detected, then judge whether there is the high data of width, length, width and height data are merged if having, if continuing to examine without returning
It surveys.
Further, the merging length, width and height data, specifically:
The high data of the width that will test and length data are merged with same coordinate system, are formed vehicle's contour data, are obtained vehicle
Length, width and height data.
Preferably, the width and height of fleet vehicles are acquired, and the length of acquisition fleet vehicles uses laser fan-shaped
Scanning sensor.
Preferably, the speed of the driving vehicle is 1~100km.
A kind of fleet vehicles outline data acquisition based on laser scanner technique, comprising:
The high scanning laser sensor of at least one width on each lane, the high scanning laser sensor of the width, for adopting are set
Collect the width and height of driving vehicle, forms the high data of width；
At least one length scanning laser sensor on each lane is set, and the length scanning laser sensor is for acquiring
The length of driving vehicle, formation length data；And
Data analysis control, the data analysis control generate vehicle's contour for merging the high data of width and length data
Data.
Preferably, the lane is bicycle road or multilane.
From the above technical scheme, the present invention acquires number by the different scanning angle of scanning laser sensor simultaneously
According to realization is not parking to carry out profile scan to multiple vehicles, and carries out conversion merging to data, generates vehicle's contour data, mentions
Rise whole efficiency.
Detailed description of the invention
Fig. 1 is the method flow diagram of the preferred embodiment of the present invention；
Fig. 2 is system block diagram of the invention.
Specific embodiment
The preferred embodiment of the present invention is described in detail with reference to the accompanying drawing.
The present invention acquires the width and height of fleet vehicles, and the length of acquisition fleet vehicles is swept using laser sector
Sensor is retouched, the speed for the driving vehicle that can detecte is 1~100km.
The lane of vehicle driving is bicycle road or multilane, and multilane is scanned simultaneously, can increase laser appropriate
The quantity of scanning sensor, but each lane should at least have a length scanning laser sensor and one high wide laser to sweep
Sensor is retouched, more accurate outline data can be improved in multiple high scanning laser sensors of width.
Embodiment 1
2 wide high sensor is individually positioned in the upper left corner and the upper right corner (6-7 meters of the height) of each lane scanning area, 1 long
Degree sensor is placed on the centre (6-7 meters of height) of 18 meters of position in front of each lane scanning area.When vehicle enters each
When the scanning area of lane, the not parking high data of width and length data for recording certain moment eventually form the number of contours of entire vehicle
According to.
Embodiment 2
2 wide high sensor is individually positioned in the upper left corner and the upper right corner (6-7 meters of the height) of each lane scanning area, 1 long
Degree sensor is placed on the position among each lane scanning area (6-7 meters of height).It is swept when vehicle enters each lane of width
When retouching region, the not parking high data of width and length data for recording certain moment eventually form the outline data of entire vehicle.
Embodiment 3
1 wide high sensor is placed on the middle (6-7 meters of height) of each lane scanning area vertically downward, and vertical road is long
Direction scanning is spent, 1 linear transducer is placed on middle position (6-7 meters of height), and vertically downward, road length direction is swept on the way
It retouches, when vehicle passes through, records different scanning data, vehicle's contour data are converted to by 3D.
As shown in Figure 1, the present invention is based on the fleet vehicles outline data acquisition methods of laser scanner technique, comprising:
S1, initializing sensor；
The width and height of the fleet vehicles of S2, acquisition bicycle road or multilane form the high data of width；
S3, the high data of current width are judged, if the current high data of width are continuously detected, thens follow the steps S4；If current
The high data of width are not detected, and then follow the steps S6；
The length of the fleet vehicles of S4, acquisition bicycle road or multilane, formation length data；
S5, the high data of the width that will test and length data are merged with same coordinate system, are formed vehicle's contour data, are obtained vehicle
Length, width and height data, and back to continuing to test after S1；
S6, the high data of width are judged whether there is, if thening follow the steps S5, if without continuing to test later back to S1.
It is using No. 1 sensor ground vertical point as origin, by two groups that same coordinate system is established in the present invention, in merging data
Data reduction is denoised at identical coordinate system, and to data, forms vehicle's contour, calculates vehicle length, width and height.In more vehicles
By when, the high sensor of multiple width and multiple linear transducers can be used, the data of these sensors can be switched to same
In coordinate system, each linear transducer can identify the presence or absence of vehicle, finally by after all Data Integrations, to outline data
Grouping, if having gap between outline data group and being greater than 30cm, it is believed that be the outline data of a vehicle.
As shown in Fig. 2, the present invention also provides a kind of fleet vehicles outline data acquisition system based on laser scanner technique,
Include:
The wide high scanning laser sensor 1 of at least one being arranged on each lane, the high scanning laser sensor of the width, for adopting
Collect the width and height of driving vehicle, forms the high data of width；
