Abstract
Methods of route planning for a moveable device and associated systems are disclosed herein. In representative embodiments, the method includes (1) downsampling a 3-D point cloud generated by a distance-measurement component of the movable device to obtain a downsampled point cloud; (2) extracting ground points from the downsampled point cloud; (3) analyzing the ground points in a surface-detecting direction; and (4) identifying an object based at least in part on the downsampled point cloud and the ground points. The identified object and the ground points can be used for planning a route for the moveable device.
Claims27
A method for identifying an object located relative to a movable device having a distance-measurement component, the distance-measurement component being configured to generate a 3-D point cloud, the method comprising:
- downsampling a 3-D point cloud generated by the distance-measurement component to obtain a downsampled point cloud;
- extracting ground points from the downsampled point cloud;
- analyzing the ground points in a surface-detecting direction;
- and
- identifying the object based at least in part on the downsampled point cloud and the ground points.
9-31. (canceled)
A system for identifying an object located relative to a movable device, the system comprising:
- a distance-measurement component configured to generate a 3-D point cloud;
- a computer-readable medium coupled to the distance-measurement component and configured to:
- downsample the 3-D point cloud generated by the distance-measurement component using voxel grids to obtain a downsampled point cloud;
- extract ground points from the downsampled point cloud;
- analyze the ground points in a surface-detecting direction;
- and
- identify the object based at least in part on the downsampled point cloud and the ground points.
