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.
Highlights
The recreational craft industry, which includes the building of crafts, motors and equipment, as well as the associated services sector, has an important economic impact on employment and turnover in Europe [1,2]
Before beginning the deck measurements, the Proliner was calibrated by the manufacturer, and several tests were performed in the laboratory to obtain the relative accuracy of both measurement systems
After proving that Proliner and the camera were well calibrated, and that the errors were inside the admissible margins for each piece of equipment, the deck measurement was started
Summary
The recreational craft industry, which includes the building of crafts, motors and equipment, as well as the associated services sector, has an important economic impact on employment and turnover in Europe [1,2]. The recreational craft industry is characterised by products with high added value and by the use of manufacturing techniques with fairly low technical level, where the skill and experience of workers is decisive in the quality of the final product. We have analyzed only a specific CMM, the Proliner 5.7, since it is the equipment used by the company that has partially supported this work. This is a small company that cannot afford great expenditures on equipment, so we are only interested in low cost systems
