| 总结: | Lines plan drawings play a very important role in the fields of naval architecture and ship design. The drawings can be used for generating a three-dimensional (3D) surface model for ship hull and in performing many useful calculations such as ship hydrostatics, stability and powering. The survey process becomes very useful when dealing with ships or boats do not have proper lines plan drawings or in the absence of hull drawings. Various methods can be used to achieve the survey process such as laser and photogrammetry methods. Photogrammetry is used in case of inaccessibility or in which photogrammetry is the only possible way to be used. In this study, close range photogrammetry was used to survey the hull form of two boat models. The overall length of the first model is 0.71 m, while the length of the other one is 2.5 m. Commercial photogrammetry software was used for image processing to predict the lines of the two models. Moreover, the photogrammetry results of the large model have been exported into commercial naval architecture software to produce a fair hull surface model and to get the hydrostatic particulars for this model. Results obtained indicated that method developed was able to obtain good lines plans for the boat models. |
