The use of digital image for volume determination using digital close range photogrammetric method

Abstract

Calculation of excavation and filling volumes is an important issue in engineering works especially in earthwork project. Various surveying methods can be used in the determination of volume in civil engineering field. At present practice, volume estimation is based on measurement carried out by land surveyor. Close range photogrammetry offers comprehensive approach in various fields such as engineering surveying, architecture and archaeology. The need of the estimated location of target point information has been carried out in previous research for volume calculation where it consumed time for field data acquisition. In this study, attention is given to the coordinate and relative orientation method that is available in Australis software for volume determination. For relative orientation module, the estimated coordinate of the target point is not required. The test of this study is based on physical model and actual object. The result of the computed volume from close range photogrammetry data is compared with the conventional method to determine the accuracy of volume. In this study, the volume accuracy achieved is greater than 90%. This study proved that close range photogrammetry is successfully used for the application of volume computation.
