The present situation in this field is now: the four-wheel positioning system that no matter whether needs go-cart, it is installed to all necessary centering installations on automobile fixture and destination disk in testing process, and target is demarcated, because the centering of fixture is installed and is made workman must, the fixture screw rod total travel of travelling, make every effort to reach the installation degree of accuracy of trying one's best high at work.Also extended thus the time of whole four-wheel positioning process.
Summary of the invention
The invention provides a kind of eight target four-wheel positioning systems.It allows testing staff to carry out relatively rough, easy target installation by the target fixture of quick-clamping, thereby accelerates detection speed and the labour intensity that alleviates survey crew.
The present invention includes target, target fixture, the horizontal Beam of camera and computing machine; The horizontal Beam of the camera left and right sides is all provided with digital camera, and four target fixture difference clampings are on the wheel rim of four wheels; It is characterized in that target has eight, on each target fixture, be fixed with two targets, one on each target fixture in two targets forms the first measurement subsystem with digital camera, and another on each target fixture in two targets and digital camera form the second measurement subsystem; Computing machine obtains the separate four-wheel locator data of two covers from the first measurement subsystem and the second measurement subsystem respectively; Computing machine generates four-wheel location verification result by the computing of two three dimension system compensating modules according to two cover four-wheel locator datas.
As a further improvement on the present invention, in eight targets, there are four to be that preposition target, four are rearmounted targets; Preposition target is tabular, has 24 circular marks to be arranged in 6 row 4 column matrix on it; Rearmounted target is tabular, has 36 circular marks to be arranged in 6 row 6 column matrix on it; On each target fixture, be fixed with a preposition target and a rearmounted target, all preposition targets belong to the first measurement subsystem, and all rearmounted targets belong to the second measurement subsystem.
Use two three-dimensional four-wheel positioning system of the present invention, can reach Fast Installation and can accurately measure, greatly reduced four-wheel positioning time, improve maintenance production efficiency.
The present invention has advantages of that operation is fast and convenient, and the suitable diaxon vehicle to various models detects.

Embodiment
The same with traditional four-wheel positioning system, the present invention includes target, target fixture, the horizontal Beam of camera and computing machine; The horizontal Beam of the camera left and right sides is all provided with digital camera; Digital camera is connected to computing machine.
Different from legacy system is that the present invention has configured eight targets, on each target fixture, be fixed with two targets, one on each target fixture in two targets forms the first measurement subsystem with digital camera, and another on each target fixture in two targets and digital camera form the second measurement subsystem; Computing machine obtains the separate four-wheel locator data of two covers from the first measurement subsystem and the second measurement subsystem respectively; Computing machine generates four-wheel location verification result by the computing of a dual system compensating module according to two cover four-wheel locator datas.
Below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.
Referring to Fig. 1 and Fig. 2.There is a horizontal Beam 2 of camera being arranged on column 3 in place, four-wheel location, and detected storing cycle is on lifting machine 7, and headstock is towards the horizontal Beam 2 of camera; The horizontal Beam 2 of camera is each side fixed with one or two digital camera 4.
Target fixture 1 is ready-package target fixture, has four to be that preposition target 5, four are rearmounted targets 6 in eight targets; On each target fixture 1, be fixed with a preposition target 5 and a rearmounted target 6, wherein preposition target 5 is fixed on comparatively forward position on target fixture 1, rearmounted target 6 is fixed on target fixture 1 comparatively by rear position, and front and back target mutually staggers in setting height(from bottom).
Referring to Fig. 3 and Fig. 4, the present invention has two measurement subsystems of working respectively.
The first measurement subsystem comprises: the preposition target in detected vehicle left side front-wheel, the preposition target in detected vehicle left side trailing wheel, the preposition target in detected vehicle right side front wheel, the each digital camera in preposition target, both sides and the computing machine in detected vehicle right side rear wheel; That is all preposition targets belong to the first measurement subsystem.
The second measurement subsystem comprises: the rearmounted target in detected vehicle left side front-wheel, the rearmounted target in detected vehicle left side trailing wheel, the rearmounted target in detected vehicle right side front wheel, the each digital camera in rearmounted target, both sides and the computing machine in detected vehicle right side rear wheel; That is all rearmounted targets belong to the second measurement subsystem.
Referring to Fig. 5, when native system work, control respectively the first measurement subsystem and the second measurement subsystem is once taken, obtain front two cover images, then in short distance, move forward and backward the position (go-cart) of detected vehicle, again the first measurement subsystem and the second measurement subsystem are once taken, two cover images after obtaining, computing machine overlaps image to front and back two to carry out image recognition and target three-dimensional coordinate and solves and just can obtain the separate four-wheel locator data of two covers.The computing module of computing machine necessity in operation legacy system, also need to call a two three dimension system compensating module, dual system compensating module can be eliminated according to the feature separately of two cover four-wheel locator datas and eliminate because the next deviation of the fast rough mounting strap of target fixture generates four-wheel location verification result accurately.Four-wheel location verification process can show on display, printer printable go out four-wheel location probation redport.
Referring to Fig. 6 and Fig. 7, as the optimal design of native system, preposition target is tabular, has 24 circular marks (circular pattern) to be arranged in 6 row 4 column matrix on it; Rearmounted target is tabular, has 36 circular marks (circular pattern) to be arranged in 6 row 6 column matrix on it.Target pattern through optimal design can be accelerated arithmetic speed, improves accuracy of detection and accuracy.
Native system can arrange two digital cameras (each one of left and right), and at this moment two digital cameras all participate in the shooting work of the first measurement subsystem and the second measurement subsystem;
Native system also can arrange four digital cameras (each two of left and right), and four digital cameras are divided into two groups (every groups have left and right shooting first), and wherein one group of camera participates in the shooting work of the first measurement subsystem; Other one group of camera participates in the shooting work of the second measurement subsystem.
