Problems solved by technology

[0014] The purpose of the present invention is to provide a method for locating agricultural machinery, agricultural machinery vehicles and storage media, so that after the base station signal is interrupted, the inertial navigation unit is not added, and the problem of short-term interruption of the signal of the automatic driving system of agricultural machinery is only solved by an algorithm, which saves product costs. Under the premise, realize the positioning of the vehicle position with high precision

Abstract

The invention provides an agricultural machinery positioning method, an agricultural machinery vehicle and a storage medium. The method comprises the steps of judging whether receiving of a base station signal is interrupted or not; when it is determined that the base station signal is interrupted at the current moment, judging whether the heading is normal; and calculating the optimal position coordinate estimated value of the agricultural vehicle at the current moment according to the observed position coordinate at the current moment, the course judgment result, the real-time vehicle speed,the time interval and the course angle. According to the invention, low-cost and high-precision positioning is achieved.

Description

technical field [0001] The invention relates to the field of automatic driving control of agricultural machinery, in particular to an agricultural machinery positioning method, an agricultural machinery vehicle and a storage medium. Background technique [0002] The automatic driving system of agricultural machinery is composed of the vehicle-mounted part of agricultural machinery and the ground base station. Type base station, fixed base station or ground-based augmented network (CORS), etc. [0003] The rapid development of self-driving cars in recent years has become the focus of competition among OEMs and even IT companies. Accurate vehicle position and heading are critical to autonomous driving. Fusing multi-source information to estimate position, heading and position delay time has become an urgent problem to be solved. The automatic driving system of agricultural machinery guides the automatic driving operation of agricultural machinery. The vehicle-mounted satell...
