Abstract

Some practical applications require surveyors to perform dimensional measurement and generate three dimensional (3D) computer models of the measured objects. The measurement tasks could be carried out using close range measuring instrument such as total stations, cameras, or scanners. The accuracies of measurement vary from micron to cm levels. Currently, majority of the measurement systems employ digital technology, and provide the data in digital form, which could be used for 3D modeling. This research involves the collaboration between the Faculty of Geoinformation Science & Engineering, UTM and the Faculty of Mechanical Engineering, UTM. In this research, several measurement systems (photogrammetric, total station, Coordinate Measurement Machine, and laser scanning) were tested for measurement and modeling of several objects. The results indicate the practicality of photogrammetric system, in terms of speed, reliability, flexibility, and accuracy.
