GeoSpark: Sparking up Point Cloud Segmentation with Geometry Clue

no code implementations14 Mar 2023 Zhening Huang, Xiaoyang Wu, Hengshuang Zhao, Lei Zhu, Shujun Wang, Georgios Hadjidemetriou, Ioannis Brilakis

For feature aggregation, it improves feature modeling by allowing the network to learn from both local points and neighboring geometry partitions, resulting in an enlarged data-tailored receptive field.

NHA12D: A New Pavement Crack Dataset and a Comparison Study Of Crack Detection Algorithms

1 code implementation2 May 2022 Zhening Huang, Weiwei Chen, Abir Al-Tabbaa, Ioannis Brilakis

In the comparison study, crack detection algorithms were trained equally on the largest public crack dataset collected and evaluated on the proposed dataset (NHA12D).

Geometric Digital Twinning of Industrial Facilities: Retrieval of Industrial Shapes

no code implementations10 Feb 2022 Eva Agapaki, Ioannis Brilakis

This paper devises, implements and benchmarks a novel shape retrieval method that can accurately match individual labelled point clusters (instances) of existing industrial facilities with their respective CAD models.

CLOI: An Automated Benchmark Framework For Generating Geometric Digital Twins Of Industrial Facilities

no code implementations5 Jan 2021 Eva Agapaki, Ioannis Brilakis

This paper devises, implements and benchmarks a novel framework, named CLOI, that can accurately generate individual labelled point clusters of the most important shapes of existing industrial facilities with minimal manual effort in a generic point-level format.

Instance Segmentation of Industrial Point Cloud Data

no code implementations24 Dec 2020 Eva Agapaki, Ioannis Brilakis

The challenge that this paper addresses is how to efficiently minimize the cost and manual labour for automatically generating object oriented geometric Digital Twins (gDTs) of industrial facilities, so that the benefits provide even more value compared to the initial investment to generate these models.

3D Semantic Parsing of Large-Scale Indoor Spaces

no code implementations CVPR 2016 Iro Armeni, Ozan Sener, Amir R. Zamir, Helen Jiang, Ioannis Brilakis, Martin Fischer, Silvio Savarese

In this paper, we propose a method for semantic parsing the 3D point cloud of an entire building using a hierarchical approach: first, the raw data is parsed into semantically meaningful spaces (e. g. rooms, etc) that are aligned into a canonical reference coordinate system.
