Row axially, i.e. move by upward and downward displacement；Due to adjusting rod I 4 and the hand of spiral of connecting rod 6 on the contrary, passing through rotation adjusting lever II
5, mounting bracket can be achieved in above-below direction, i.e., the fine setting in short transverse.Adjusting rod I 4 can also by with the lower end of montant 3
The cooperation in different installation and adjustment holes 31 carrys out further mounting bracket in above-below direction, i.e., the fine setting in short transverse.
As shown in figure 8, multiple installation and adjustment holes at equal intervals are machined with video camera mounting rod 7.On video camera mounting rod 7
The installation and adjustment hole in portion coordinates with the mounting hole 12 on cross bar 1, can adjust the height spacing on video camera and ground.Video camera is installed
Graduated scale mounting rod 8 is installed to aid in installing graduated scale in the bottom of bar 7.Graduated scale is used for sentencing for wheel and ground object relative position
It is disconnected.As shown in figure 9, graduated scale mounting rod 8 is made up of square tube, its middle part be machined with mounting hole with the bottom of video camera mounting rod 7
Connection.Video camera mounting rod 7 is made up of pipe in the present embodiment.
During test, first, make, assemble above-mentioned mounting bracket, this mounting bracket is located at the front portion of headstock, front hatch cover
Surface, cross bar 1, by the way that the cushion block 2 with certain angle is fixedly mounted, ensure this support parallel to the horizontal vertical plane of vehicle
Levelness.Ensure support and left and right vehicle wheel direction and above-below direction by adjusting the relative position on montant 3 and cross bar 1
Limit, realize mounting bracket in above-below direction, i.e., the fine setting in short transverse by adjusting rod I 4 and adjusting rod II 5.Secondly, will
External camera is installed in this mounting bracket, for shooting the change for the relative position for catching vehicle and lane line；Video camera
Above the side of tested wheel of vehicle, while recording wheel running orbit, the normal steering operation of vehicle is not influenceed.
The position of outside vehicle camera installation：Horizontal direction is located at vehicle outside, and has certain spacing, and this spacing can pass through shooting
The relative position of machine mounting rod 7 and cross bar 1 adjusts；Vertical direction has certain spacing with ground, and this spacing can be by taking the photograph
The relative position of camera mounting rod 7 and cross bar 1 and by select different mounting holes of the video camera on video camera mounting rod 7 come
Adjustment., can be by the graduated scale on graduated scale mounting rod 8, to aid in determining vehicle and ground in camera coverage
The relative position of the objects such as lane line.Then, by interior video cameras installation in the car, track change early warning system is caught for shooting
The unlatching of system and mask information.Finally, using the video camera synchronous acquisition relevant information in the inside and outside portion of vehicle, i.e. track changes pre-
When alert function is opened/shielded, deviation speed, the positional information of vehicle, and the information of inside and outside camera acquisition is carried out to score
Analysis, thus evaluate and test the quality that the track changes warning function.
Specifically, interior video cameras collection test vehicle speed, warning system start, at the end of mark；Outside is taken the photograph
Camera gathers the distance of wheel and lane line, and due to there is time shaft inside the video of shooting, therefore wheel can be calculated
To the speed of track line skew.The video time axle of inside and outside camera acquisition is synchronous, therefore can analyze and alarm
System starts/end of identification when, wheel is now apart from the position of lane line, and calculates migration velocity now.Contrasted with this
As a result, evaluation system function admirable is required according to exploitation.
The present invention has made the Simple installation support outside a car, for the camera head of outside vehicle to be fixedly mounted.This
Support is located at the front portion of headstock, and the surface of front hatch cover, parallel to the horizontal vertical plane of vehicle, video camera is arranged on institute's test carriage
Above the side of wheel, while recording wheel running orbit, the normal steering operation of vehicle is not influenceed.Positioned at headstock front deck table
The holder part in face, by the way that the cushion block with certain angle is fixedly mounted, ensure the levelness of this holder part.Support relative to
Vehicle around and above-below direction displacement restriction, installation is relatively fixed by vehicle body position above support and wheel
Realized.The position of outside vehicle camera installation：Horizontal direction is located at vehicle outside, and has certain spacing, and this spacing is simultaneously
And it can adjust；Vertical direction has certain spacing with ground, and this spacing can adjust.In camera coverage, one can be installed
Graduated scale, for aiding in the relative position of the object such as vehicle and ground lane line.Simple in construction, use is easy to adjust, versatility
It is good, it can be used for a variety of vehicles.
The present invention carries out vehicle and lane line relative position information, car by installing high-speed camera in the inside and outside portion of vehicle
Deviate the synchronization catch of early warning system job information in road.The test of lane departure warning function is realized, method is simple, operation letter
Single, cost is low.
Mounting bracket of the present invention can realize the adjustment with lateral direction of car position relative position, the adjustment of vertical direction；Pass through
Installation with vehicle is fixed, and the displacement of support and rotary freedom can all realize control.Support can be adjusted symmetrically.Present invention system
Make simple processing, low manufacture cost, installation operation process is simple, does not destroy body construction.
Exemplary description is carried out to the present invention above in conjunction with accompanying drawing, it is clear that realization of the invention is not by aforesaid way
