Abstract

The invention discloses a device and method for measuring the offset of an intelligent driving vehicle combined navigation antenna. The measuring device includes a base provided with a base coordinate system adapted to the coordinate system of the combined navigation, and a mounting seat is arranged at the origin of the base coordinate system , three probe rods distributed along the circumferential direction are rotated on the mounting base, and a range finder is installed on the top of each probe rod; the measurement method is: install the integrated navigation and antenna; make the coordinate system of the base and the coordinate system of the integrated navigation Parallel; adjust the three probe rods so that the three rangefinders are not on the same straight line; the position of the probe rod remains unchanged, adjust the angle of the rangefinder, and measure the vertical distance to the coordinate axis in the base coordinate system to obtain the rangefinder itself Coordinate position; measure the straight-line distance to the origin of the integrated navigation and the straight-line distance to the center point of the antenna respectively; obtain the offset of the antenna to the integrated navigation based on the measured value. The invention has the advantages of simple structure, convenient operation and high measuring precision.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a device and method for measuring the offset of an intelligent driving vehicle integrated navigation antenna. Background technique [0002] After the intelligent driving vehicle is installed with integrated navigation (a navigation system that combines two or more navigation devices), it is necessary to accurately measure the antenna (the device used for integrated navigation to receive satellite signals and calculate its own position and attitude) to the combined navigation system. The offset of navigation is used to calculate the position and attitude of the vehicle, etc., and the higher the accuracy of the measurement, the higher the accuracy of the calculation. Because integrated navigation is generally installed inside the vehicle, and the antenna is generally installed on the roof because it needs to receive satellite signals, there is a large error in direc...
