Stats
Autonomous vehicles require accurate positioning and mapping solutions, especially in situations involving automatic lane changes and environmental awareness. GPS suffers from measurement errors up to a dozen meters, unsuitable for precise navigation in complex urban or tunnel scenarios. SLAM can estimate vehicle attitude in real-time while mapping the surrounding environment, with LIDAR SLAM and Visual SLAM as the two main categories. Visual SLAM offers advantages like informativeness, ease of installation, and cost-effectiveness, contributing to its popularity in autonomous driving systems.
