The Role of Photogrammetry for Forensic Analysis

Device:Canon camera EOS R6 Full Spectrum
Targets:6 3DF Zephyr coded markers
Lighting:Torches with standard, infrared and ultraviolet lighting
Tags:Photogrammetry, Forensics, Documentation
Over the last few years, photogrammetry has proven to be a very effective tool for digital data collection in the vast field of forensic investigations, going way beyond the “simple” photo acquisition.

In this case study, we will show you how this method can be truly helpful with some 3D projects that we of 3Dflow made together with Canon Italy and forensic experts, using Canon’s EOS R6 Full Spectrum camera for the photo acquisition and 3DF Zephyr photogrammetry software for the data processing, with the aim to replicate some of the most common forensic scenarios.

The Cheongnaru Pavilion in Cheongna Lake Park, Incheon, South Korea

Aerial Photogrammetry, Drone Survey, RTK, UAV, Mapping

Cheongna Lake Park, South Korea

Many thanks to our Korean reseller Koseco for kindly providing us with the data for this case study focused on the so-called “Cheongnaru Pavilion” (“청라루”), a Korean traditional building located on the north side of Cheongna Lake Park, a public park located in Incheon, South Korea.

Their main goal was to retrieve and reconstruct the building using aerial drone photogrammetry, in order to extract a high-resolution 3D model to use for promo purposes while also delivering for their customers a perfect reference of those ancient vibes steeped in Korean history.

Photogrammetry + LiDAR with the DJI Zenmuse L1

Aerial Photogrammetry, LiDAR module, Mapping, Drone Survey

San Lorenzo Guazzone, Province of Cremona, Italy

Many thanks to Simone Dall’Asta of DL Droni for sharing with us the data for this case study, showcasing an aerial survey made over a small town in the province of Cremona (Lombardy, Italy) with the drone DJI Matrice 300 RTK equipped with Zenmuse L1 technology.

This new solution that integrates RGB data from pictures and LiDAR aims at the best accuracy possible of the final output, both in terms of geometry and texture. Besides, in this case study, you will see the specific step-by-step workflow to follow in 3DF Zephyr.

3D Photogrammetry for Projectile Deformation Analysis

Photogrammetry, Forensics, Ballistics, Projectiles, Project Analysis

Foz do Iguaçu, Brasile

Many thanks to Forensic expert Rafael Rodrigues Cunha for providing us with all the data for this case study, focused on a photogrammetry technique tested to assess projectile deformation using 3DF Zephyr. The study showed how photogrammetry can significantly help forensic applications and ballistic studies.

The project has been fully presented during InterForensics 2021, considered the most important Forensic Science event in Latin America that took place on November 2nd to 5th, 2021 in Foz do Iguaçu/pr, Brazil.

Worldwide Award to the discovery of the Faida rock reliefs

Duhok, Kurdistan Region, Iraq

Two years ago, the team of the “Kurdish-Italian Faida Archaeological Project” (KIFAP) found ten Assyrian rock reliefs in Faida, northern Iraqi Kurdistan. The archaeological mission was conducted by Professor Daniele Morandi Bonacossi from the Department of Humanities and Cultural Heritage (DIUM) of the University of Udine together with the Directorate of Antiquities of Duhok.

We are incredibly proud of having contributed with 3DF Zephyr to this wonderful finding, awarded as the most important archaeological discovery of 2019 and winning the International Archaeological Discovery Award “Khaled al-Asaad”.

The Verruca Fortress

Architecture Survey, Aerial Photogrammetry, UAV Systems, Cultural Heritage, Laser Scanning

Pisa, Tuscany region, Italy

Professor Giovanni Pancani from the Architectural Department DIDA of University of Florence, Italy, carried out a surveying project affecting the so-called “Verruca” Fortress together with Ph.D. Matteo Bigongiari and a group of his students.

This ancient fortress, located upon the homonymous Mount Verruca in the Province of Pisa (Tuscany, Italy), is in an advanced state of decay; for this reason, the goal of this project was its 3D reconstruction, using both photogrammetry and laser scanning, to extract further outputs, essential to perform instrumental analysis through the study of the morphological profile of the rock and identify the degree of damage and deformation.

Photogrammetry for hull design and boat modeling

Marine Engineering, CAD Drawing, Reverse Engineering

Cancun, Mexico

Marine Engineer Edgar Tovar of A.T. Suministros S.A. de C.V. showcased a workflow in which he combined photogrammetry, CAD drawing, and reverse engineering to hull and boat 3D reconstruction using 3DF Zephyr Lite, Rhinoceros 7, and Orca3D.

Qingyang, Gansu, China

Christiane Zhao from Weiss AG kindly provided us with the data for the following case study, which showcases all the workflow steps for the 3D reconstruction of the Qingyang Bei shi ku si (referred to as “North Grotto Temple” in this article), one of the four major cave temples in Gansu province, Northwest China.

Over time, it has been facing several physical threats, and to properly ensure its conservation, a multidisciplinary team digitalized the temple by using a 360° HDR camera.

The Zerveilla Dam – Photogrammetry for TV Show’s VFX

Vals, Grisons Canton, Switzerland

Digital artist Chris Blaser of VFX Swiss company g3D art-e-motion has recently been scanning the Zerveilla dam located in a reservoir near Vals, Switzerland, by means of drone photogrammetry combined with Lidar scans. The 3D models of the dam were used as part of references and digital props for the VFX shots of season 4 of a Swiss TV show called “Wilder”, directed by Claudio Fäh and produced by c-films.

Archeologia Invisibile Egyptian Museum Turin

The exhibition “Archeologia Invisibile” at Museo Egizio of Turin

Temporary Exhibition, Archaeology, Archaeometry

Turin, Piemonte, Italy

All the data collected for this case study have been kindly provided by the Photography Department of the Museo Egizio of Turin, which set up a truly innovative temporary exhibition named “Archeologia Invisible” back in March 2019. Archaeometry played a key role for this exhibition along with photogrammetry, whose aim was that of unveiling the unique hidden stories of several archaeological findings through their 3D models and the usage of disciplines such as chemistry, physics and radiology that went beyond their exterior appearance.
