Tesmec launches 3D digital twin integrated system

Published by
Global Mining Review,

Tesmec recently launched its brand new mobile mapping system (MMS) at bauma 2022 – an integrated radar mapping system of the underground and high-precision digital 3D survey system for the environment above.

The MMS is equipped with a detection system installed on the top of an Explorer 2.0 Georadar. The survey system is designed to perform a geo-referenced 3D reconstruction through the union of two types of data: the 3D point cloud obtained through the use of LIDAR technology; and the 3D point cloud obtained through stereoscopy algorithms, applied to the images acquired by high resolution matrix cameras. The resulting point cloud with the image superimposed is then subjected to a digital re-elaboration processing, carried out by sophisticated artificial intelligence networks in order to get geo-referenced and accurate mapping.

The MMS detection system has an accuracy of approximately 2 cm, and returns a cloud of points of the surrounding environment that can be consulted on the cloud platform, useful for proper planning of the construction site.

Explorer 2.0 is the Tesmec very high precision geo-radar equipped with 32 antennas that scan the ground up to a depth of 96 cm, and which is able to operate, towed by the vehicle, at a maximum speed of 17 km/hr. The output generated by Explorer 2.0 consists of the mapping of existing underground infrastructures, useful for preliminary excavation investigations. In fact, the use of the geo-radar allows for a reduction in the execution time of works, which helps guarantee the safety of construction sites and allows greater precision in excavation work, avoiding the possibility of damage to existing underground utilities.

The integration of the two surveys makes it possible to get a 3D digital mapping on a cloud platform, on which the as-built map, generated by SmartTracker Tesmec, can be superimposed.

An integrated dashboard with a GIS engine is available through a web platform for displaying the information from the surveys and processing, which allows the georeferenced and simultaneous display of data. The specially configured interfaces allow navigation within different types of data, such as visible images and high-resolution videos, thermal images, laser point clouds, and three-dimensional BIM models.

Marco Quarta, New Technology Manager at Tesmec, comments:

“The Mobile Mapping System is a solution that can be combined with excavation technology and is complementary to it. The digital transformation has naturally pushed us towards the creation of a new portfolio of technologies and business models.

“This is a further step towards the supply of integrated solutions for the underground laying of high-tech cables. The product is part of the group’s growth strategy, under the banner of digitalisation, sustainability and energy transition, with the aim to bring the advanced image processing and artificial intelligence skills acquired by the group in different verticals to markets that are still unexplored.”
