Abstract

The invention relates to the technical field of navigation, in particular to a multi-sensor fusion mapping system and a method thereof. The multi-sensor fusion mapping system comprises a path planningmodule, a data collecting module, a data fusion module and a mapping module. The sensors used by the multi-sensor fusion mapping system are laser radar and GPS; the multi-sensor fusion mapping is used. Compared with single-sensor mapping, the method using the multi-sensor mapping has the advantages that a more precise and more effective map can be obtained; the data collection is segmented collection; if data in a certain segment is wrong, the re-collection by a user can be realized; the error-tolerant rate and the data collection efficiency can be greatly improved. The system can consume less time, and the final result can be faster and more precisely obtained.

Description

technical field [0001] The present invention relates to the technical field of navigation, and more specifically, to a multi-sensor fusion mapping system and method thereof. Background technique [0002] With the development of the times, navigation has become a hot topic of research. Navigation brings us a lot of convenience. However, automatic navigation is also a relatively popular research. In navigation, the most important thing is the construction of maps. The relatively novel composition is lidar mapping or GPS mapping. However, these two methods have great defects. The error of lidar mapping may be relatively large, while GPS mapping is completely dependent on satellites. signal of. Contents of the invention [0003] In order to overcome at least one defect of the above-mentioned prior art, the present invention provides a multi-sensor fusion mapping system and its method, and obtains a brand new map by using data fusion of laser radar and GPS. [0004] Compare...
