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.
