Image acquisition:	a digital camera
Signal Processing:	DSP
Measuring system:	2 group industrial camera, four goals reflex plate and special software
Measuring principle:	The camera takes a candid photograph of the dynamic car wheel, car body
	and level surface on the speed of 0.5 seconds/times. The geometrical image
	will be contrasted with a predetermined standard image, and then got the
	four-wheel location data through calculation formula.

Measurement methods:

1. got a complete measurement through lifting vehicles

2. All the measurements completed through moving vehicles

3. The static measurement (not open)

Help system:

1. Built-in help operation software, help users grasp and used correctly

2. Built-in 3d adjusts software, help users adjust and repair the chassis fault effectively and quickly.

3. Guide menu, easy to find the models data

Stable accuracy:

1. the stability of 3D product has been raised with his simple structure, advanced technologies,

non light, temperature disturbance and non hidden faults of electronic, circuit, batteries of

traditional four-wheel alignment.

2. Measurement precision of 3D is more stable and reliable with non requirements of the

accuracy for clamp, rims and lift platform

3. Non 0 points shift in 3D product, so only one calibration for forever use.
