Vehicle measurement device and calibration method

A vehicle measurement device, comprising:

• a base module;
• a column module comprising a fixed column, a movable column assembly, and a drive assembly, wherein the fixed column is fixedly connected to the base module, the movable column assembly is movably mounted to the fixed column, the movable column assembly is connected to the drive assembly, and the drive assembly is configured for driving the movable column assembly to lift or lower relative to the fixed column;
• and
• a cross-beam module supported by the movable column assembly and configured for supporting a calibration element for calibrating an auxiliary driving system of a vehicle;
• wherein the drive assembly is further configured for driving the cross-beam module to lift or lower relative to the movable column while driving the movable column assembly to lift or lower relative to the fixed column;
• a camera assembly mounted to the cross-beam module for acquiring an image associated with the vehicle;
• and
• wherein the drive assembly is configured to drive the movable column assembly in both a same direction and an opposite direction of the cross beam module.
