Special Issue Information

Dear Colleagues,

Recently, the importance of 3D surface measurement has been increasing, not only in industrial quality management but also in underwater applications. Every year, more and more 3D measurements are utilized in applications such as the exploration of shipwrecks or archaeological sites; the quantification of fish sizes or coral reef growth; and the inspection of industrial facilities such as offshore platforms, pipelines, and underwater structures. The variety of 3D surface measurement principles is wide. Laser scanners, ultrasound methods, and structured light techniques all have their advantages and disadvantages and have each become preferred in different fields of application. However, the expectations of the users concerning the observed space, measurement time, robustness and accuracy, and the ability to perform the observations during movement are by far not yet satisfied.

This Special Issue aims to collect new developments and research results concerning underwater 3D surface measurement. Authors are encouraged to submit novel research results concerning considerable improvements, new surface measurement techniques, and exciting applications in this fascinating field of research.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

A new underwater 3D scanning device based on structured illumination and designed for continuous capture of object data in motion for deep sea inspection applications is introduced. The sensor permanently captures 3D data of the inspected surface and generates a 3D surface model in real time. Sensor velocities up to 0.7 m/s are directly compensated while capturing camera images for the 3D reconstruction pipeline. The accuracy results of static measurements of special specimens in a water basin with clear water show the high accuracy potential of the scanner in the sub-millimeter range. Measurement examples with a moving sensor show the significance of the proposed motion compensation and the ability to generate a 3D model by merging individual scans. Future application tests in offshore environments will show the practical potential of the sensor for the desired inspection tasks. Full article
