High accuracy underwater inspections are getting more and more important in the underwater industry where time and cost optimization represent nowadays the main innovation drivers. The subsea industry is undergoing a digital transformation process and for this reason, methods that can provide real-time accurate 3D digital measurements are increasin...

Metrology is fundamental in all the applications that require to qualify, verify and validate measured data according to standards or, in other words, to assess their compliance with predefined tolerances. At sea, metrology is commonly associated with the process of measuring underwater structures, mainly pipeline elements widely used in offshore i...

This chapter introduces several state of the art techniques that could help to make deep underwater archaeological photogrammetric surveys easier, faster, more accurate, and to provide more visually appealing representations in 2D and 3D for both experts and public. We detail how the 3D captured data is analysed and then represented using ontologie...

In this paper we present a photogrammetry-based approach for deep-sea underwater surveys conducted from a submarine and guided by knowledge-representation combined with a logical approach (ontology). Two major issues are discussed in this paper. The first concerns deep-sea surveys using photogrammetry from a submarine. Here the goal was to obtain a...

In this article, we present an approach for a deep-sea survey based on photogrammetry using a remotely operated underwater vehicle (ROV). A hybrid technique gives us real-time results, sufficient for piloting the ROV from the surface vessel and ensuring a uniform coverage of the site, as well as recording high-definition images using an onboard com...

Nous présentons ici une approche du relevé sous-marin à grande profondeur, par ROV, fondée sur la photogrammétrie. Une technique hybride nous permet d’obtenir des résultats en temps réel, suffisants pour guider le ROV depuis le navire de surface, assurer une couverture homogène du site, et enregistrer sur un ordinateur embarqué les images à haute r...

Since a decade, we develop a photogrammetry tool dedicated to monitoring red coral populations. This tool is used to collect, effectively, accurate data for the study of population dynamics of red coral. In this article, we present new developments that automate the steps of calculating scale and orientation of images. This automation is made possi...

The new advance in photogrammetry using the automatic procedures such as the famous algorithm which was proposed by David Lowe (Lowe, 2004) features descriptors and matching (SIFT) and then the recent development of external orientation (Nister (Stewenius et alii, 2006) or Snavely (Snavely et alii, 2010)) have changed drastically the way of measuri...

We propose in this paper a broad-coverage approach for multimodal annotation of conversational data. Large annotation pro-jects addressing the question of multimo-dal annotation bring together many dif-ferent kinds of information from different domains, with different levels of granula-rity. We present in this paper the first re-sults of the OTIM p...

The multiplication of annotation schemes and coding formats is a severe limitation for interoperability. We propose in this pa-per an approach specifying the annotation scheme in terms of typed feature struc-tures, that are in a second step translated into XML schemas, from which data are encoded. This approach guarantees the fact that no informati...
