摘要：Engineering deformation monitoring requires techniques which can produce high precision and accuracy, reliable measurements at good temporal resolution and fast processing speed. Moreover, monitoring in civil engineering is generally considered to be labour- intensive and financially expensive, and it can take significant effort to arrange the necessary human resources, transportation and equipment maintenance. Such requirements are especially true for monitoring non-rigid membrane structures (defined in this paper as covers or enclosures in which a fabric surface is pre-shaped and pre-tensioned to provide a shape that is stable under environmental loads). Low cost, automated, photogrammetric techniques therefore have the potential to become routinely viable for the structural monitoring of non-rigid membrane structures in the future. This research is investigating the use of close range photogrammetry to be applied at all stages of membrane structure engineering, from materials testing, through dimensional control in construction to in-situ, as-built monitoring of the finished construct. In order to establish a low cost, generic structural monitoring system, a comprehensive understanding of the capability of close range photogrammetry is necessary. Unlike general commercial integrated monitoring systems, the components of the low-cost monitoring system being developed are not especially designed for structural monitoring purposes. This paper therefore reports on experiments conducted to test the capability and reliability of the various components which are utilised in this system to ensure this combination can be applied for high-precision measurement tasks
