Embodiment Construction

[0026] One aspect of the present technology relates to a method for identifying an object positioned relative to a movable device. In a representative embodiment, a movable device has a distance measurement component configured to generate a 3-D point cloud. The method includes (1) downsampling the 3-D point cloud generated by the distance measurement component to obtain a downsampled point cloud; (2) extracting ground points from the downsampled point cloud; (3) analyzing ground points along a surface detection direction; and (4) identifying the object based at least in part on the downsampled point cloud and the ground points.

[0027] Another aspect of the technology relates to a system for identifying an object positioned relative to a movable device. In some embodiments, the system includes (i) a distance measurement component configured to generate a 3-D point cloud, and (ii) a computer readable medium coupled to the distance measurement component. The computer readabl...

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 forthe moveable device.

Description

technical field [0001] The present technology generally relates to methods and related systems for planning a route of a movable device, such as a ground vehicle or an unmanned aerial vehicle (UAV). More specifically, the present technology relates to methods for analyzing point clouds generated by distance measurement components using voxel grids or three-dimensional (3D) grids. Background technique [0002] Range finding and distance measurement techniques are important to the task of route planning for vehicles. After the odometry or distance measurement process, the user can collect raw data associated with objects in the surrounding environment. The raw data collected often includes a large amount of information that requires further analysis. Analyzing the collected raw data can be time-consuming and sometimes challenging due to time constraints or other constraints such as limited computing resources. Accordingly, an improved system that can effectively and efficie...
