Description

technical field [0001] The present application relates to the technical field of intelligent vehicles, and in particular, to a high-precision map testing method, device, electronic device and storage medium. Background technique [0002] Autonomous driving technology is the frontier of current vehicle intelligence technology. Autonomous driving can reduce traffic accidents, reduce fuel use and energy consumption, and can fundamentally change road traffic of people and goods, benefiting the entire society. Development and verification of autonomous driving Work is highly valued by the industry. [0003] It is difficult to achieve advanced autonomous driving solely by local perception. Usually, advanced autonomous driving needs to be combined with high-precision maps. High-precision maps can allow autonomous vehicles to perceive abnormal scenes ahead and achieve safer driving. [0004] Among them, verifying the application of high-precision maps in autonomous driving is an im...

Problems solved by technology

[0006] In the existing scheme, the real vehicle test method is adopted, and test scenarios need to be built. However, some test scenarios are more complicated and the construction cost is higher

[0007] In addition, at the stage when the autonomous driving algorithm is still immature, if the algorithm is directly deployed on a real vehicle to run autonomous driving for high-precision map testing, it is easy to cause traffic accidents and pose a safety hazard
