Description
Technical field
It measures and tries the present invention relates to tyre skidding, and in particular to a kind of tyre skidding based on edge enhancing identification measures examination
System and test method.
Background technology
The abrasion condition of tire in actual use is one of factor that vehicle safety is concerned about the most.Indoor abnormal tyre mill
Damage test and analysis technology is widely used in the production test link of tire enterprise, but how quick and precisely effectively analysis is taken turns
Tire inordinate wear is still the important directions of domestic and international tire wear measuring technology exploitation.
Currently available technology method is such as：Patent publication No. is CN206496732U, and patent name is a kind of rolling tire tire
Face slides measuring system, refers to that the displacement method wear test system of the tire friction energy testing machine of view-based access control model is main in the patent
Be by tire pre-define mark point, rear drive tire rolled on transparent glass platen so that tire and platen
Rolling and sliding friction occurs, journey is moved by the cameras capture tire being placed under glass table plate, passes through computer vision
Method confirms and tracks and records the mark point on tire, so as to calculate tyre surface mark enumeration slippage, can further calculate
Go out the abrasion condition of tire.
Due to tire because the deformation of friction generation itself is smaller, the vision collecting system of testing machine is proposed
Very high requirement.The shortcomings that current displacement method wear test system both domestic and external, mainly includes following aspect：
Tire interface boundary judges inaccurate.The side that current illumination scheme is mostly illuminated using single light source or double light sources
Method since algorithm only needs to track the mark point being in contact with tyre surface, needs the dry of the mark point for avoiding having been moved off contact
It disturbs.During entire creeping of tyre, tire and ground contact phase, due to mark point with during ground friction variation compared with
To be slow, and the angle of contact surface and light source is smaller, and uniform illumination larger by the part of light source irradiation, and therefore tracks
Difficulty is relatively low.But when tire has just contacted ground or in the case of just leaving ground, leave the tyre surface of above ground portion with
The angle consecutive variations of light source lead to the brightness irregularities of the sectors of tread, and are currently according to tire and ground contact surface
Brightness and the brightness of tire rest part are distinguished to determine tire interface boundary, in the case where illumination condition is fabulous, contact site
The brightness for dividing the brightness of tyre surface and disengaging sectors of tread has larger contrast, can preferably determine that tire connects with ground
Tactile boundary.And in the case of general illumination condition, contact portion tyre surface is approached with disengaging the brightness of sectors of tread, because
This is difficult to accurately distinguish the boundary that tire is contacted with ground.
The tracking accuracy of special tire is inadequate.In terms of accurately capturing mark point contact ground and leaving ground motion, no
It is also different with the tire effect of decorative pattern shape.For common tire in moving process, each section variation is more uniform, is less prone to
Mutation, therefore the 30Hz sampling systems that can be used at present track.And in rectangular rib tire moving process, square
Decorative pattern can generate larger deformation in ground is contacted, and the deformation is released in tire and the moment that ground disengages,
A larger displacement is generated, and is measured with the sampling system of current 30Hz, since sampling number is very few, the position of acquisition
The situation of tire wear can hardly be reflected by moving Dependence Results.
On the other hand, dynamic sliding measures and the measurement of quiescent ground footprint shape is often deployed in different system respectively
On, patent publication No. CN106626994A, the method for detection wheel movement of the foetus state vertical load during a kind of vehicle of patent name travels
And system, it refers to using displacement sensor in the patent, displacement below the spring of every axle both ends loading carriage is installed and is passed
Sensor by the variation of measurement sensor mounting plane distance to the ground, and integrates the shadow of air pressure and environment temperature to tire size
Ring, so at calculating on vehicle tire real-time deflection.This method has the function of single-measurement tyre load, and cannot measure
Tire frictional behaviour, and consider influence of the vehicle self structure characteristic to tyre load over the ground, measurement accuracy is limited.

Data are automatically imported in the mechanical hard disk of massive store, data acquisition.
Image is passed through at the enhancing edge that tire and ground Contact Boundary are formed according to the laser that laser projects first
Noise reduction, binaryzation obtain characteristic point, least square fitting characteristic point are recycled, so as to calculate image boundary position and shape
Shape.For the image data stored in hard disk is virtualized, we are according to edge determination mark point during tire motion
It is no to be contacted with glass table plate.The identification of mark point uses ROI, and a significant notation point is only included in each ROI, and corresponding one has
Imitate coordinate, at the same using automatic discrimination with manually adjust be combined by the way of realize detection to mark point ROI region.It should be noted
Be mark point spacing to be controlled, interfered to avoid ROI is caused.To the mark point in ROI using the method for calculating barycenter, pass through
Binaryzation and Blob analyses, mark point centroid position coordinate is obtained using position Weighted Average Algorithm.It obtains per every in frame image
Behind the position of a mark point barycenter, shift value of each mark point in adjacent moment can be not only calculated, but also can obtain
Each slip value of the mark point between this moment and time of contact, it is final to calculate mark point history sliding curve.
For static state pressurization rear tyre edge detection, tire interface boundary changes, and laser irradiation range reduces, so as to
Difference obtains characteristic point by image noise reduction, binaryzation, and the method for recycling least square fitting characteristic point obtains new boundary
Position and shape.By the calculating of different boundary characteristics, we can realize the detection of quiescent ground footprint shape.
The software that workstation controller carries is respectively that video acquisition and image processing software and DDA analysis are soft
Part.Wherein, the function of video acquisition and image processing software mainly includes：System parameter setting, video image acquisition, storage and
Playback, camera calibration automatically determine ROI region, and can realize and manually adjust, the parameter setting of ROI region, and mark point is known
Not, position calculates and data export, and calculates and describe the ground connection mark boundary of any time.The function of DDA analysis software
