Low-Cost 3D workshop

Brescia, Italy: 12-13 December 2024

8th International ISPRS Workshop

Low-Cost 3D - Sensors, Algorithms, Applications

Low-Cost 3D (LC3D) is a series of international ISPRS workshops on low-cost three-dimensional sensor systems and tools, ranging from low-cost acquisition devices like handheld scanning systems over inexpensive photogrammetric algorithms to processing software and applications. Initiated by Prof. Frank Neitzel from Technical University Berlin and Prof. Ralf Reulke from Humboldt-University in Berlin, the workshops were initially organized and hosted in Berlin (2011, 2013, 2015). In 2017 the 5th workshop was hosted by the HafenCity University Hamburg, in 2019 the 6th edition of the workshop took place at INSA Strasbourg, France while in 2019 at the University of Würzburg, Germany.

The 8th edition of the ISPRS Low-Cost3D workshop will be organized in Brescia (Italy) on 12-13 December 2024 at the University of Brescia

The event will be held in conjunction with the Optical 3D Metrology (O3DM) workshop. These are two complementary ISPRS scientific events that will provide delegates with a wide range of topics centred on 3D reconstruction and optical 3D measurement systems and applications. Participants could join both events with just one registration fee.

The main focus of the ISPRS LC3D workshop is to discuss new developments in low-cost 3D sensor technology, algorithms, and applications. 

Topics include:

Real-time visual localisation framework for satellite-based navigation

Reliable operation of global navigation satellite systems (GNSS) for positioning, navigation, and timing (PNT) is essential for applications, e.g., in communication and transport. Disruptions to GNSS threaten safety and security. The EU-funded Egeniouss project aims to enhance European GNSS services by creating an accurate, cost-effective cloud service. This service incorporates innovative multi-sensor navigation with visual localization to address GNSS challenges. Initially, it will feature an application programming interface for smartphones and drones, showcased in three case studies. Following successful validation, the service will expand for broader applications.

State-of-the-art in forensic photogrammetry

Geosurveying has been used in police investigations for several years, mostly to survey traffic collisions. In recent years, optical 3D metrology has replaced typical accident surveying and has found its way into several other areas of forensic work, including forensic pathology. Specifically, low-cost sensors enable smaller police units to perform state-of-the-art incident documentation. However, optical 3D metrological data is not only acquired to document scenes and traces but also to perform advanced reconstructions of incidents. The aim is to provide deeper insight for the court and enable more adequate judgment.

Traditional to AI-based 3D scene capture and modeling

Artificial intelligence (AI) has been demonstrated to offer breakthrough potential for numerous applications. This presentation will delve into how AI has revolutionized the field of 3D scene capture, creating more realistic and accurate 3D models. For this purpose, the presentation will review major developments in 3D scene capture from traditional methods to recent state-of-the-art techniques in terms of neural radiance fields (NeRF) and 3D Gaussian Splatting, as well as respective variants to further increase robustness and handle complex scenarios. Finally, the remaining limitations of current methods, as well as potential directions for future work, will be discussed.
