Abstract
The invention relates to a small target 3D (three-dimensional) automobile four-wheel position finder, belonging to the technical field of automobile inspection and solving the defects that a target of a 3D four-wheel position finder in prior art is large in size and wide in automobile measuring width, so that the application range is narrower, and the practicability is poorer. The small target 3D automobile four-wheel position finder mainly comprises a photographing device and a target measuring filed, wherein the photographing device comprises a driving board; the driving board is arranged on a transverse beam; 5 mega-pixel cameras with fill-in lamps are arranged at the two ends of the transverse beam; a microcomputer is connected with the driving board and the cameras through data lines; the target measuring field comprises two light reflecting targets A and two light reflecting targets B, wherein the sizes of the light reflecting targets A range from 300cm2 to 350 cm2, and the sizes of the light reflecting targets B range from 130cm2 to 160 cm2; and elevating machine vertical columns are arranged around a track platform.
Description
Technical field
The present invention relates to a kind of small tenon target 3D vehicle four-wheel position finder, it belongs to the Vehicle inspection technical field.
Background technology
Theoretical according to automotive engineering, tire is installed to must meet certain angle requirement on the vehicle body, and wherein topmost angle has toe-in angle, camber angle, kingpin inclination, kingpin castor angle etc.Vehicle is after a period of time of going, and these parameters possibly change, and influences the usability of vehicle; This just need remeasure and adjust vehicle; And the instrument of measuring is exactly a vehicle four-wheel position finder, and the 3D four-wheel position finder is a brand-new measuring technique, and it utilizes computing machine to graphical analysis and calculating; Set up space coordinates, calculate the positional parameter of vehicle tyre.
During with 3D vehicle four-wheel position finder drawings parameter, require vehicle is placed on the lifting machine, then target is installed on the tire of vehicle.Like this, the width of measuring overall width and be exactly car body adds the width of two targets, usually between 2.4-2.7 rice.Width is mostly about 2.6 meters between four traditional post lifting columns, and a lot of cars are measured the intercolumniation width that width have just exceeded the lifting machine, and the camera at orientator two ends can't photograph complete target, also just can't be used for measuring the four-wheel locator data.Such user or buy ultra wide lifting machine again, or abandon measurement maintenance service to a great deal of vehicle.Use the 3D four-wheel position finder to cause very big restriction or waste to the user like this.
The way that addresses this problem is at present changed the lifting machine exactly, and a kind of is the shearing type lifter that does not have column, and a kind of is the special use four post lifting machines that are used for the 3D four-wheel position finder, and the intercolumniation width reaches 3 meters.But the price of these two kinds of lifting machines is all a lot of than the confidential height of traditional lifting, and the user need eliminate the traditional lifting machine that is using, and it is very big that the back floor area is installed, and has increased the difficulty of selecting for use in a lot of tyre repairs shop.
Summary of the invention
It is big that the target size that the present invention is directed to 3D four-wheel position finder in the prior art is big, vehicle is measured width, and cause the deficiency that usable range is less, practicality is relatively poor, and a kind of small tenon target 3D vehicle four-wheel position finder is provided.
The technical scheme that the present invention solves the problems of the technologies described above is following:
A kind of small tenon target 3D vehicle four-wheel position finder; Comprise photographic means and target measuring field; Said photographic means comprises drive plate; Said drive plate is installed on the crossbeam, and said crossbeam two ends are provided with the camera that has the light filling lamp of 5,000,000 pixels, and microcomputer links to each other with camera with drive plate through data line; In the said microcomputer computer software is installed, said computer software comprises the software such as calculating and man-machine interaction of the resolving of foundation, volume coordinate point, the four wheel locating parameter of Flame Image Process, space coordinates; Said target measuring field comprises that two are of a size of 300 ~ 350cm
2Reflective target first and two are of a size of 130 ~ 160cm
2Reflective target second; Be provided with lifting machine column around the said track platform.
Compared with prior art; The invention has the beneficial effects as follows: the present invention adopts novel software algorithm; Employing is lacked a lot of amount of image information than traditional technology and is accomplished measurement; Adopt 5,000,000 high pixel camera simultaneously, reduce the loss of significance that causes in order to remedy small tenon target image information, thereby can the target size be decreased to 1/3rd of traditional product.When vehicle is carried out the tire positioning parameter measuring, reduced the measurement width of vehicle, make the user of a lot of original traditional four post lifting machines can accessible use 3D four-wheel position finder, avoided user's eliminating too early and waste to existing equipment.All cars can be realized normal measurement on four traditional post lifting machines like this, and the user of original lifting machine is brought great convenience, greatly reduce cost of investment.

Embodiment
Below in conjunction with accompanying drawing principle of the present invention and characteristic are described, institute gives an actual example and only is used to explain the present invention, is not to be used to limit scope of the present invention.
A kind of small tenon target 3D vehicle four-wheel position finder; Comprise photographic means and target measuring field; Said photographic means comprises drive plate 3; Said drive plate 3 is installed on the crossbeam 5, and said crossbeam 5 two ends are provided with the camera that has light filling lamp 21 of 5,000,000 pixels, and microcomputer 4 links to each other with camera 1 with drive plate 3 through data line; Said target measuring field comprises that two are of a size of 300 ~ 350cm
2Reflective target first 7 and two are of a size of 130 ~ 160cm
2 Reflective target second 10; Be provided with lifting machine column 6 around the said track platform 8.
The present invention in use; At first vehicle 9 is positioned on the track platform 8; Then two reflective target first 7 and two reflective target second 10 are respectively installed on the front and back tire of vehicle 9, lifting machine column 6 gives rise to proper height with vehicle 9 then, utilizes 1 pair of reflective target first 7 of camera to take pictures with reflective target second 10; And the image of taking is transferred to microcomputer 4, accomplish through the computer software analyzing and processing image information of microcomputer 4 and measure.
