3D Four-wheel aligner only takes 2 or 3 years popular in the country after it It was introduced by us.This kind of product with the advantages of measurement of high efficiency& low failure rate & high technology are widely recognized by users,automobile maintenance industry is adopted by more and more users in our country which trendwill replace the conventional laser and CCD wheel alignment .

First Generation ：3D Four-wheel aligner products
At present ,there is more than thirty or forty domestic 3D aligner manufacturers,although they have professed their products are the real 3D aligner, few factories canreally master the core technology,most of them just imitate the earlier product abroad , technology of which is relatively backward,there is a big gap to compared with foreign similar products in the developed countries ,
It can be said that the domestic product is still at the level of the first generation if dividing by the era of foreign products and technical progress.

The main symbol of generation is industrial camera products,such as the earlier product of  SNAPON USA being used 1.3MP camera,A lot of 3D four-wheel aligner in the current market have a problem:the latter image data will cut part of the data in the prior image before it finished transmittance,and that will cause a “mixture”data consists of the prior image and the latter image.If the vehicle is moving,the actual position of target in the prior image and latter image is not collapsed,and the image sended back is distorted,and can’t be used to calculate the space coordinates.If the vehicle is moving , then the actual position target of two front and back pictures is not overlapping,
Therefore,this first generation of 3D four-wheel aligner must shoot in the specified location .vechicle measurement process must be proceed as the following steps:

Under the vehicle still state, shooting once on the target for more than 3 seconds ,pushing the  vechicles back from some distance ;
Under the vehicle stationary state, shooting the second on the target for 3 seconds or more ,pushing the vechicle to let vehicles back to the start position

Compared with the first generation of products ,the basis of hardware on the second generation of 3D four wheel aligner is comprehensive upgrade ,But one of the most key is the great breakthrough in the software algorithm core,the breakthrough being finish independently by   researchers in Yan Tai GaoYi and they have applied for national invention patent. Not only proving that Chinese did not go the old way of imitate, copy ，crack, and the fake products abroad,  but also proving that lead the world in 3D Four-wheel aligner technology development trend.

So, what is the amazing performance on the second generation of 3D Four-Wheel aligner?
As we all know , 3D four-wheel aligner must push the vehicles when we are operating measurement ,However the second generation of D Four-wheel aligner ---  Unique Skill “Free Style Pushing”.However ,the second generation of 3D four-wheel aligner -  "Free Style Pushing", making the vechicle smooth, fast and convenient.
Describing the operation flow  the  first and second generation product,  you can clearly see the advantage and charm of "Free Style Pushing"as the following pictures:

The first generation

The second generation

Figure 2 Show:It is not a point but a area to reached the position , giving an optional choice space ,without waiting for a pause and smooth & natural operation process to the operator .
As you can see, the“Free Style Pushing” making the operation process  simple and increasing  the greatly efficiency of measurement ,this is the benefit of science and technology innovation to the people .

Some first generation of products also profess they are “Free Style Pushing”or they look like “Free Style Pushing”.But seeing is not necessarily believing,Although they have done some technology improvement, such as raising the camera pixels, selecting  the  faster operation computers, etc.By a pre-designed vechicles distance to make the vechicles demo process much faster this  way to confuse the consumers ,But in practical , the operator cannot be pre-set  distance,So the problem of the "accurate to reach " specify the location still exist when  pushing the vechicle , it won't be also able to reproduce the effect of presentation.

Using the 3D Four-wheel technology to replace the operation way on the screens, waiting of the first generation products is the  inevitable trend on 3D Four-wheel aligner,and any manufacturer of domestic and international are unable to avoid.No progress will  be eliminated eventually, only improving on the level of appearance, without  promoting   the core technology, even if you make the copperplate upgrade to platinum,  just the old wine in new bottles.What we called glory of  "big brands" will only hide outdated technology temporarily .
Something advanced will break through the traditional resistance and show  its vitality and strong vitality.
Of course, “Free Style Pushing” also has the greater  improvement space by itself .Recently ,
Much more "free" of “Free Style Pushing”technology will be available,the computer will not necessary to give the directions,Operator can choose the  forward or backward optionally  and can also push the vechicle repeatedly according according to their  personal wishes.
Computers will only tell you that  "I"  have finished the measurement , you can let it goes.
As we all know ,the core component of 3D four-wheel aligner is an industrial camera.
At that time the first generation products are restricted by industrial camera technology and choosing the only 1.3 MP camera.Because of low pixels of the image,the pictures of shooting is  not so clarity,it brought the difficulties for image calculation processing and guarantee the accuracy of measurement.

Due to the rapid development of industrial  camera technology in recent years,high pixel industrial camera is not no longer so expensive ,it provides an important condition to produce 3D Four-wheel aligner.
JPLY CEO ,Manager Pei , He began to do the research and development on industrial camera , with the professional technical ability of digital imaging and innovation & breakthrough boldly .Recently JPLY customized a few four-wheel aligner cameras when making the solutions of four-wheel aligner to the customers.G1GD05C with 5.0MP or more on the dedicated industrial camera and it also added 64MB buffer memory inside . The so-called "Buffer Memory" takes the shooting picture  stored in the specific camera area,This establish the buffer between the speed photograph and data transmission and guarantee complete of each image to transmitted the computer.
Our camera have also added the external synchronization function ,which can control the two camera taking pictures at the same time, this two cameras being mount on the two target images of  the front & back wheels on the left and right respectively,to guarantee the real images at one moment to reflect the position relation of four target.
