Abstract

The invention discloses an indoor positioning method based on V2X technology, which belongs to the field of parking lot vehicle positioning, and comprises the following steps: receiving and analyzinga basic safety message sent by a vehicle; according to the basic safety message sent by the vehicle, obtaining vehicle characteristics, and carrying out vehicle identification and matching; preliminarily positioning the matched vehicle position to obtain the relative position of the vehicle in the detection area; acquiring a reference position of the detection area, and performing coordinate conversion on the reference position of the detection area and the relative position of the vehicle to obtain an absolute position of the vehicle; receiving and analyzing the roadside safety message, and analyzing the position information of the vehicle; updating the position information of the vehicle to realize the final positioning of the vehicle; the method depends on V2X roadside equipment data exchange, can be applied to underground and indoor parking lots, is accurate in positioning, and is low in vehicle side requirement and accurate and comprehensive in information compared with other methods.

Description

technical field [0001] The present invention relates to parking lot vehicle positioning, in particular to an indoor positioning method based on V2X technology. Background technique [0002] When the vehicle enters the parking lot, the GNSS signal is weak, resulting in inaccurate positioning information. The necessary condition of the time-based measurement and positioning method is that the time of the equipment in the positioning system is accurate and synchronized, and the time of the positioned vehicle is usually determined by its own position. Information (GNSS) calculated, the two are contradictory. [0003] Surrounding devices that use the same method to obtain positioning will transmit positioning errors to the positioned vehicle, resulting in error accumulation. Contents of the invention [0004] According to the problems existing in the prior art, the present invention discloses an indoor positioning method based on V2X technology, which includes the following st...
