The invention relates to a three-dimensional high-precision map drawing method based on vehicle-mounted laser inertial navigation data. The method comprises the following steps of Step 1, positioningthe transverse offset of running tracks in the running process of a collection vehicle; Step 2, correcting road plane running tracks; Step 3, building a three-dimensional high-precision map; and Step4, checking geographic information and road three-dimensional linear data by a terminal in real time through APP application software of a mobile phone, and performing three-dimensional high-precisionmap navigation. The method provided by the invention has the advantages that the high-speed high-efficiency road-network-level automatic collection of road geometric parameters can be realized; the data collection difficulty and manpower consumption are reduced; errors caused by vibration and deviation of a detection vehicle in road geometric detection are eliminated; and the measurement accuracyis improved.
Description
technical field [0001] The present invention relates to the research field of automatic road detection technology, automatic driving technology and three-dimensional scene reconstruction technology, in particular, a three-dimensional high-precision map drawing method based on vehicle-mounted laser inertial navigation data. Background technique [0002] Autonomous driving is the future development trend of smart transportation. Building a three-dimensional high-precision map based on big data and realizing map data sharing is an indispensable part of autonomous driving. However, traditional GIS maps cannot meet the needs of autonomous driving, mainly due to: 1) It is difficult to update locally, and high-frequency road renovation and expansion cannot be reflected in time; 2) The map accuracy is low and cannot meet the requirements of autonomous driving operations; 3) Two-dimensional maps cannot stereoscopically reflect the interaction and overlapping relationship of multi-lay...
