Creation of a reference point | Download Scientific Diagram By using the loop closure optimization process, the LiDAR self-localization error is decreased by 29.4%, and the global environmental reconstruction precision is increased by 12%. Can a research paper follow a story arc? Explore how Freytag’s Pyramid can make scientific writing more engaging, structured, and impactful First, LiDAR sensors are used to scan the indoor scene vertically in all directions. The iterative closest point (ICP) algorithm is used to predict the spatial transformation matrices of the LiDAR sensor between the successive frames based on the retrieved virtual corners. Then, the random sample consensus (RANSAC) algorithm and the three-axis least-squares method (3A-LSM) are used to precisely determine the plane equation of the calibration object in the LiDAR point clouds.
