Lidar Only Approach

Lidar-only approaches focus on utilizing LiDAR sensor data exclusively for tasks like 3D mapping, object detection, and odometry, aiming to reduce reliance on other sensors like cameras or GPS. Current research emphasizes improving the accuracy and robustness of these methods, exploring techniques such as continuous-time trajectory estimation, novel point cloud representations (e.g., Gaussian voxel maps), and adaptive sampling strategies to optimize data acquisition. These advancements are significant for applications in autonomous driving and robotics, particularly in GPS-denied environments, by offering cost-effective and potentially more reliable solutions for perception and localization.
