Abstract

The invention discloses an integrated navigation antenna offset measurement device and method of an intelligent driving vehicle. The measurement device comprises a base provided with a base coordinatesystem matching an integrated navigation coordinate system. A mounting base is arranged at the origin of the base coordinate system, three feeler levers distributed in the circumferential direction are rotationally mounted on the mounting base, and a distance measuring instrument is rotationally mounted at the top end of each feeler lever. The measurement method comprises the following steps: installing an integrated navigator and an antenna; enabling a base coordinate system to be parallel to a coordinate system of the integrated navigator; adjusting three feeler levers to enable three a distance measuring instruments to be not on the same straight line; if the position of the feeler lever is not changed, adjusting the angle of the each distance measuring instrument, and respectively measuring the vertical distances of coordinate axes in the base coordinate system to obtain the coordinate position of each distance measuring instrument; respectively measuring a linear distance to an integrated navigator origin and a linear distance to an antenna center point; and acquiring an offset of the antenna to the integrated navigator based on the measurement value. The device is simple instructure, convenient to operate and high in measurement 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...
