Abstract

The invention discloses a method and system for verifying high-precision map data. The method includes loading high-precision map data and establishing a three-dimensional driving scene; establishing a display window at any monocular relative position of the simulated driver in the three-dimensional driving scene ; driving the display window to simulate the vehicle moving forward along the driving path; simulating the driver to observe the three-dimensional driving scene and mark wrong data on the interface of the display window. The present invention can perform simulated driving along the driving path in the three-dimensional driving scene established by high-precision map data from the perspective of the simulated driver, and find and record the error data of the high-precision map data in the simulated driving for engineering personnel to search and amendments.

Description

technical field [0001] The present invention relates to the technical field of geographic information, in particular to a device and method for verifying high-precision map data by simulating a driver's perspective. Background technique [0002] With the development of autonomous driving technology, unlike traditional digital maps, high-precision map technology for providing a large amount of road data information has become a must. [0003] The establishment of traditional high-precision maps is mainly to import basic geographic information or collected remote sensing images into the geographic information system in order to reduce errors as little as possible. It is necessary to verify the data of the high-precision map. [0004] The verification method of high-precision maps is generally based on six perspectives for data verification; during the verification process, considering the huge impact of different perspectives on the verification data, it is necessary to conti...
