Application of Close Range Photogrammetry to Deck Measurement in Recreational Ships

Abstract

In this article, we present results that demonstrate the utility of close range photogrammetry in the measurement of decks in recreational craft as an alternate measurement system to the one based on direct acquisition of coordinates. The areas of deck covered with teakwood for aesthetic or security reasons were measured. Both methods were compared in terms of precision of measurements, time consumption, equipment cost, and ease of manipulation and equipment transportation. Based on the results, we conclude that photogrammetry has advantages in almost every aspect with respect to the direct method. Consequently, photogrammetry is suggested as a suitable method for coordinate measurement of decks in recreational ships. However, in some special circumstances, where ships have wide corridors with few obstacles the direct method can be more appropriate than the photogrammetric method.

Automated as-built 3D reconstruction of civil infrastructure using computer vision: Achievements, opportunities, and challenges

“…Ref. [107] surveyed the perimeters and areas in pieces of boat decks with assistance of coded targets for photogrammetric auto recognition and reconstruction. This type of output is of particular usefulness to engineering applications requiring high reliability such as deflection monitoring of structural members, length measurement for quality assurance, geometric profile preservation, and reversemodeling of structural parts.…”

Use of photomodeler as a measuring and management tool in construction projects

“…Construction process is a process during which construction products are being made and includes several subprocesses, which recursively include other sub processes. Construction projects during their accomplishment in the field require much time and expense, and close management control of them is required if they are to be completed within the established time, cost limitations and within prescribed quality [1][2][3][4][5][6][7][8][9].…”

Combined Close Range Photogrammetry and Terrestrial Laser Scanning for Ship Hull Modelling

“…The research [21] suggested photogrammetry as a suitable method for coordinate measurement of decks in recreational ships. The research involves the photogrammetry modelling process, noting that, in the cases of wide corridors for the ships, with few obstacles, the direct method is relevant, when compared to the photogrammetric method.…”

“…The maritime and shipyard industries clearly demand the new 3D modelling technique for the construction process control of ships, control during operation, and model deformation in the rebuilding process. The research [21] shows that, in selected cases, the photogrammetry technique is sufficient for ship modelling, which sometimes needs additional, supportive measurements.…”
