Embodiment Construction

[0028] The technical solutions of the present invention will be apparent from the drawings of the present invention. Based on the embodiments in the present invention, all other embodiments obtained without creative labor are not made in the premise of creative labor.

[0029] Nowadays, it is true that the satellite signal is true, no interference or tampering, in the peace years, intentional interference or tampering civilian satellite signals, but if we have, we have no way to respond, then significant accident.

[0030] When the literature retrieval, several technical solutions to solve the problem were found, but the lack of programs that were able to completely solve this problem are to present a solution that can completely solve this technical problem. like figure 1 As shown, this embodiment provides an unmanned vehicle navigation positioning method, including the following steps:

[0031] S1, making a number of positioning flags with unique and fixed identification feature...

Abstract

The invention discloses a pilotless automobile navigation positioning method and system and a storage medium. The method comprises the steps: making a plurality of positioning marks with unique and fixed recognition features, and installing the positioning marks beside a road or at any place where a pilotless automobile passes; pre-storing the position information corresponding to each positioning mark in a vehicle-mounted PLC of the pilotless automobile; identifying and reading, by the pilotless automobile, the marks through a vehicle-mounted camera to obtain the accurate position information of the marks, and transmitting the position information to the vehicle-mounted PLC; and by the vehicle-mounted PLC, comparing the position information obtained by reading the positioning marks with the position information given by a vehicle-mounted satellite positioning system to judge whether the positioning of the vehicle-mounted satellite positioning system is correct or wrong. According to the method, a large number of entity and physical positioning marks are used, the position information can be accurately obtained, trivial comparison and position information correction are carried out, then the correct positioning of the satellite navigation positioning system of the pilotless automobile can be accurately judged, and meanwhile the accuracy of navigation positioning can be continuously corrected.

Description

Technical field [0001] The present invention relates to the field of driverless cars, and specific relates to an unmanned vehicle navigation positioning method, system, and storage medium. Background technique [0002] Now no driving car internal satellite system is low in transmit power, low anti-interference performance, and civil code is open, so the car GNSS receiver is very easy to interfere with it, satellite interference is divided into two types, one It is suppressed interference, one is deceived interference. After suppressing interference, the receiver signal on the vehicle is blocked, does not have the ability to receive satellite positioning information; the other is spoofing interference, at which time the receiver can receive the satellite signal, but the signal is artificially tampering, at this time Go to the wrong positioning signal. Therefore, if the driver has been deceived, the receiver can still receive the satellite signal, and the number of visible counts w...
