Just Now In this article we describe a new convolutional neural network (CNN) to classify 3D point clouds of urban scenes. Solutions are given to the problems encountered working on scene point clouds, and a network is described that allows for point classification using only the position of points in a multi-scale neighborhood. This network enables the classification of 3D point

Frequently Asked Questions

What is pointpoint cloud classification?

Point cloud classification is a task where each point in the point cloud is assigned a label, representing a real-world entity as described above. It is different from point cloud categorization where the complete point cloud dataset is given one label.

What are the applications of 3d point clouds in civil engineering?

Today, the analysis of 3D point clouds acquired with topographic Lidar or photogrammetric systems has become an operational task for mapping and monitoring of infrastructure and environmental processes. Numerous applications require the identification and delineation of landscape objects and their properties.

What is 3d point cloud semantic segmentation for agricultural scenes?

Introduction In the field of computer vision, the three-dimensional (3D) point cloud semantic segmentation of large-scale unstructured agricultural scenes is important for perceiving the surrounding environment, autonomous navigation and positioning, and autonomous scene understanding ( Guo et al., 2020a, Guo et al., 2020b ).

What is the large scale point cloud classification benchmark?

A more recent benchmark is the “Large-Scale Point Cloud Classification Benchmark” (www.semantic3d.net) that provides labelled terrestrial 3D point cloud data on which people can test and validate their algorithms (Fig. 1). Figure 1: Example of a segmented and classified point cloud (www.semantic3d.net).
