V880 3d wheel aligner The measurement principle: Forming the basis plane and position of the quadrilateral by the four wheel centers, constituting the angle of the wheel aligner by the geometric relationship between the wheel plane and wheel plane with the basic plane together. Calculating the axis of kingpin by the wheel rotation axis during the wheel steering. Constituting run-out compensation by the wheel rotation axis while vehicle moving and angle changes of the wheel plane geometry. Four target reflectors are mounted above the vehicles four rims then scrolling wheel and continuous shooting the geometry of the reflective target board by the camera, analyzing the changes of the geometry by computer then to get the corresponding positional parameters of the wheels and chassis and so on. The technology is the use of machine vision technology and computer information processing technology. Product features: Two industrial ccd digital camera, four target goals The carts dynamic measurement. Can realize the automatic compensation of the positioning data, so that get more accurate measurement data Simple operating. Four target plates hanging on the rim then push the car to complete the traditional positioning kingpin measurement except the kingpin No need periodic calibration. Calibration is completed before leaving the factory. Measurement and the tilt are independent of impact of level of platform No electronic components on the target reflector board, very low failure rate. Lifting measuring range up to 1 meter.
