The intelligent driving industry has reached a consensus. For L3 / L4 or even higher-level autonomous vehicles, high-precision maps are an important support, and the rigid demand for high-precision maps is rapid updates. The traditional way of deploying collection vehicles cannot meet the requirements of high-precision maps. update frequency
Moreover, the current high-precision map construction method has low accuracy and robustness, and the application scenarios also have certain limitations.

The invention provides a map construction method, which comprises the following steps: obtaining crowdsourcing image data collected by each crowdsourcing source, the crowdsourcing image data of each crowdsourcing source comprising at least two crowdsourcing images; for the crowdsourcing image data collected by each crowdsourcing source, carrying out local map construction based on a first preset algorithm, and obtaining a local map corresponding to the crowdsourcing image data of the crowdsourcing source; for the crowdsourcing image data collected by any two crowdsourcing sources, carrying outsimilar frame detection based on a second preset algorithm, and determining at least one group of similar crowdsourcing images between the crowdsourcing image data of any two crowdsourcing sources; for each group of similar crowdsourcing images, calculating a relative pose between the group of similar crowdsourcing images; and based on the relative pose between each group of similar crowdsourcingimages and the local map corresponding to the crowdsourcing image data of each crowdsourcing source, carrying out map construction by adopting a third preset algorithm. The invention also provides amap construction system, a server and a computer readable medium.
Description
technical field [0001] The embodiments of the present disclosure relate to the technical field of map construction, and in particular, to a map construction method and system, a server, and a computer-readable medium. Background technique [0002] The intelligent driving industry has formed a consensus. For L3 / L4 or even higher-level autonomous vehicles, high-precision maps are an important support, and high-precision maps just need to be updated quickly. The traditional method of deploying acquisition vehicles cannot meet the needs of high-precision maps. Update frequency. Moreover, the current construction methods of high-precision maps have low accuracy and robustness, and the application scenarios also have certain limitations. SUMMARY OF THE INVENTION [0003] Embodiments of the present disclosure provide a map construction method and system, a server, and a computer-readable medium. [0004] In a first aspect, an embodiment of the present disclosure provides a map ...
