COMEX EXPERIENCE AT THE HEART OF INNOVATION

COMEX EXPERIENCE AT THE HEART OF INNOVATION

With the experience of Comex in underwater shooting, marinisation and the integration of equipment for implementation in extreme environments, the Innovation department develops and realizes solutions for underwater shooting. marine complex. From integrated systems such as ORUS 3D® (very high resolution three-dimensional modeling system for remote-controlled machines) to specific systems made on demand, the Innovation department meets the requirements of underwater vision systems for science, defense or even industry.

THE AWARD OF EXCELLENCE

THE AWARD OF EXCELLENCE

From the beginning, Comex has been at the top of the rankings for patent filings and regularly offers new products and services from its R & D. Recently, the company has developed a new contactless submarine metrology system to reproduce 3D metric models of all types of submarine structures or landscapes with submillimeter definitions.

PROJECTS

DESIGN AND INTEGRATION OF A HIGH SPEED UNDERWATER VISUALIZATION SYSTEM

 Projet d’intégration d’un système de visualisation sous-marine multi-caméras, à haute définition et à haute vitesse.

GROPLAN Project

At the confluence of Human Sciences and Computer Science, the GROPLAN project, whose fields of action are in submarine and naval archeology, brings together researchers, academics and industrialists working in France, Malta and to USA.


The central proposal of this project is the construction of an information system based on ontologies. This information system will provide a formal framework and application tools to express and manage digital content and expert knowledge in a consistent manner.

The second proposal of the project is the implementation of methods for the collection of field data and their integration within the information system during the acquisition phase. It is in this phase that COMEX will implement its very high resolution three-dimensional survey facilities for the acquisition of data on selected test sites.

In 2014, a survey was carried out on the Xlendi wreck in Malta.

Partners: National Center for Scientific Research, Aix Marseille University, SETP, University of Malta, University of Texas, COMEX SA.

LORI Project – Location and Recognition of Submerged Objects

• The high-resolution photogrammetric survey in an underwater environment has taken an operational turn with the automation of treatments and their integration into a remote-controlled machine. This new type of data, the production of which is now generalizable, opens up numerous prospects for exploitation in multiple sectors of activity, ranging from ecology to civil engineering, including oil services applications and, of course, the needs of mine warfare.

It is in this context that the LORI project proposes to exploit the high-resolution photogrammetric 3D readings to approach in an innovative angle the problems related to the identification of targets or objects and the guiding of an autonomous machine in the scene surrounding this object.

The purpose of the LORI project is to optimize photogrammetric survey techniques and to develop new approaches to object recognition. The adaptation of these techniques to their integration on an autonomous machine remains an objective to achieve. This last component implies a miniaturization of embedded electronics and the optimization of embedded computing resources.

ORUS 3D ® : OPTIMUM RECONSTRUCTION OF SUBMARINE SITES

ORUS 3D ® : OPTIMUM RECONSTRUCTION OF SUBMARINE SITES

ORUS 3D ® is a non-contact underwater measuring device for the three-dimensional and very high resolution survey of submerged sites or structures. This new tool, based on a trifocal sensor and an automatic photogrammetric processing method allows to produce digital models of high precision, scale and directly on site. The major innovations of this system are related to underwater shooting in sometimes extreme conditions and the automated processing for the production of results in real time to obtain a quality control on site. The work carried out by mixed teams of engineers from CNRS and Comex has made it possible to draw on more than 20 years of experience in underwater shooting, operational know-how and photogrammetric treatments. result in an integrated system whose performance has so far been unmatched. The speed of acquisition, the methodological advances and the automation of the processing steps make it possible to optimize the occupation time of the operational means. The ORUS 3D ® system provides data independently of any source of external positioning information. The precision of the results is thus independent of the precision of inertial units, DVL or acoustic positioning system. All the acquired data can however be georeferenced in order to reposition the model produced in an absolute reference.

The fields of application are multiple :

›› OFFSHORE OIL & GAS : metrology, chain inspection

›› EXPERTISE / CIVIL ENGINEERING : inspection of works, inspection of hulls, dams, bridge piers, mapping of debris in case of accidents at sea.

›› DEFENSEmine war

›› ARCHEOLOGYtool for digital preservation of material discovered during excavations, heritage management

›› ECOLOGY : management tool, time tracking… 

The ORUS 3D ® tool integrates easily with your ROV, bypassing traditional connections with other measurement and navigation sensors (INS / DVL / LBL), reducing installation time, measurement bias offsets, the need for a fine calibration. The interface on the ROV is done via standard connections. The system is calibrated at the factory but a control operation can be performed quickly on site using a certified calibration test pattern.
