Camera Calibration Considerations using Bullabulling’s Golden Pipeline Water section

Ainslea Kipling

Located 526km East of Perth in the Goldfields-Esperance region is the old town site of Bullabulling. Access to water in the Bullabulling area was stumbled upon by prospector John Aspinall on his way to seek his fortune in the Eastern Goldfields in March 1895.

Bullabulling is  very close to the Golden Pipeline Water Supply Scheme. The Scheme is historically significant as it has delivered water to Western Australia’s eastern goldfields from Mundaring Weir since 1903. The pipeline was commissioned in 1896 and the Engineer commissioned to carry out this significant project was C.Y. O’Connor. The "Golden Pipeline" is ranked as one of Australia’s greatest engineering achievements.

This project will conduct an Unmanned Aerial Vehicle (UAV) survey of the Bullabulling’s Golden Pipeline Water section. Capturing long objects using photogrammetry can  lead to systematic errors (doming effects) making the survey of pipelines using drones challenging. The aim of the project is to photograph the pipeline using different flight paths and heights. In addition, different types and location of control points as well as camera calibration will be investigated. The root mean square (RMS) of independent check points will be analysed and used to verify the results of the field trials to determine the most accurate method in  mapping long linear features using UAV technology.
