Recent years have witnessed enormous progress in AI-related fields such as computer
vision, machine learning, and autonomous vehicles. As with any rapidly growing field, it …

3D modeling from images and LiDAR (Light Detection And Ranging) has been an active
research area in the photogrammetry, computer vision, and computer graphics communities …

We study the problem of shape generation in 3D mesh representation from a few color
images with known camera poses. While many previous works learn to hallucinate the …

The level of detail (LOD) concept of the OGC standard CityGML 2.0 is intended to
differentiate multi-scale representations of semantic 3D city models. The concept is in …

Local density of point clouds is crucial for representing local details, but has been
overlooked by existing point cloud compression methods. To address this, we propose a …

This paper provides a comprehensive overview of urban reconstruction. While there exists a
considerable body of literature, this topic is still under active research. The work reviewed in …

The lack of floor plans is a critical reason behind the current sporadic availability of indoor
localization service. Service providers have to go through effort-intensive and time …

Virtual exploration tools for large indoor environments (eg museums) have so far been
limited to either blueprint-style 2D maps that lack photo-realistic views of scenes, or ground …

Piecewise planar models for stereo have recently become popular for modeling indoor and
urban outdoor scenes. The strong planarity assumption overcomes the challenges …

We introduce an interactive tool which enables a user to quickly assemble an architectural
model directly over a 3D point cloud acquired from large-scale scanning of an urban scene …
