Embodiment Construction
[0031] Embodiments of the present invention use high accuracy to maintain a high definition (HD) map containing the latest information. HD maps can be used by autonomous vehicles to safely navigate to their destinations without or with limited manual input. An autonomous vehicle is a vehicle that can sense its environment and navigate without human input. Autonomous vehicles may also be referred to as "unmanned vehicles", "self-driving cars" or "robot cars" in this article. HD maps are maps that store data with very high accuracy (usually 5-10cm). The embodiment generates an HD map containing spatial geometric information about roads on which autonomous vehicles can travel. Therefore, the generated HD map includes information necessary for the autonomous vehicle to safely navigate without human intervention. The embodiment generates and maintains a high definition (HD) map that is accurate and includes the latest road conditions for safe navigation.
