Abstract
Aspects of the disclosure provide a method for processing point cloud data. A plurality of frames of the point cloud data collected from an environment surrounding a pathway are classified into categories based on distances between three-dimensional points of respective frames of the point cloud data and a reference plane of the respective frame of the point cloud data. The distances indicate heights of the three-dimensional points of the plurality of frames of the point cloud data. The frames of the point cloud data of a same one of the categories that matches a pathway object are merged. Candidate point cloud data of three-dimensional points having distances from the pathway that satisfy a predetermined condition is extracted from the merged frames of the point cloud data. Point cloud data conforming to a feature of the pathway object is extracted from the candidate point cloud data.
