Abstract

The invention provides a mobile platform positioning device and method based on scene DNA. The mobile platform positioning device comprises a data acquisition unit, a calibration unit, an informationacquisition auxiliary unit and a data processing unit, the data acquisition unit comprises a forward-looking camera, a downward-looking camera and a satellite positioning module which are arranged ona fixed bracket; and the data processing unit is used for constructing a scene DNA-based map according to the information acquired by the data acquisition unit, and then performing initial positioning, image-level positioning and degree-level positioning based on a scene DNA map, so that the positioning precision of the mobile platform can be improved.

Description

technical field [0001] The invention relates to the field of vehicle positioning, in particular to a mobile platform positioning device and method based on scene DNA. Background technique [0002] In recent years, with the rise of unmanned vehicle technology, the demand for vehicle positioning, especially metrological vehicle positioning, has become increasingly urgent. Map-based vehicle positioning is achieved by matching the characteristics of the image to be positioned and the map. However, in the real environment, lighting, Weather changes and scene changes lead to changes in image features, thereby reducing the accuracy of vehicle positioning. [0003] At present, there have been some achievements in vehicle positioning, such as the authorized patent CN206960591B, the patent name is "vehicle high-precision positioning device and method based on road fingerprints", which discloses a vehicle positioning method based on road fingerprints. However, this method only uses de...
