A test was devised to measure the distortion of a ship section during and after a crane lift. As the shipbuilders expend significant man hours and costs in carrying out adjustments to fit ship sections together after lifting, it was hoped that information gained from the test could be used to make design adjustments to ensure a better fit. The test was carried out by BKS Surveys Ltd. and Harland and Wolff Ltd., the Belfast shipbuilders. 相似文献

As part of the measurements of desert terrain characteristics in the United Arab Emirates, made in support of a study of airborne radar, close range vertical stereophotographs of various natural surfaces were taken with a pair of Hasselblad MK70 metric cameras. The technique is described and the constraints imposed by the ground conditions and the need for rapid measurements are explained. Various terrain types are illustrated and the method is described whereby variables summarising surface roughness and surface slope were generated from profiles of the microrelief. From a more general discussion of current equipment and geomorphological applications of close range photogrammetry, it is concluded that this flexible technique is presently under utilised by field scientists. 相似文献

A review of some recent activities undertaken by the Institut Géographique National, France (IGN) in photogrammetry is given in this paper, especially with regard to digital and space data processing, assessment of SPOT images and the development of new instruments and experimental map products. The main topics considered can be divided into three groups: aerial surveying, digital photogrammetry and space photogrammetry (including the possibility of further planetary missions). 相似文献
