Embodiment Construction
[0054] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
[0055] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance.
[0056] As mentioned in the related background technology, in the current technology, due to the closedness of the underground garage and the instability of the light source, many equipment involved in positioning cannot improve a large amount of data, resulting in equipment failure, high navigation cost and unstable navigation effect.

The invention provides a navigation information processing method and device, electronic equipment and a storage medium. The method comprises the steps of acquiring motion state information of an automobile based on an inertial device, and acquiring vehicle information of the automobile based on a controller local area network; carrying out strapdown calculation on the motion state information to obtain navigation information; fusing the navigation information and the vehicle information by using a preset Kalman filter to obtain target navigation information, wherein an input vector of the Kalman filter is a two-dimensional vector; and navigating the automobile based on the target navigation information. The method does not need to depend on the environment to collect data, solves the problem of unstable navigation effect caused by insufficient data acquisition, fuses navigation information and vehicle information by using the Kalman filter, improves the accuracy of the navigation information, improves the positioning precision, and adopts the two-dimensional vector as the input vector of the Kalman filter, the filtering mode is simple, he hardware resource consumption is low, and the navigation cost is reduced.
Description
technical field [0001] The present application relates to the field of computer technology, in particular, to a navigation information processing method, device, electronic equipment and storage medium. Background technique [0002] At present, with the rapid development of the modern automobile industry, intelligent driving has become the development trend of the automobile industry. Intelligent driving is an important starting point for the combination of industrial revolution and informatization. It will be able to change the flow of people, resource elements and products, and subversively change human life. Intelligent driving refers to the technology that the machine helps people to drive, and completely replaces human driving under special circumstances. [0003] In related technologies, technologies such as machine vision, satellite positioning and lidar positioning are widely used in intelligent driving. However, in order to improve the accuracy, the above technolo...
