POTENTIAL OF CONSUMER-GRADE CAMERAS AND PHOTOGRAMMETRIC GUIDELINES FOR SUBSURFACE UTILITY MAPPING

Abstract. The poor documentation of subsurface utility data is a common problem in many cities, exposing field engineers to risks of utility strike. This paper investigates the use of consumer-grade cameras to improve operational efficiency on construction sites and explores different imaging networks to optimize photogrammetric processing for low-cost subsurface utility surveys. Results from the first part of the study demonstrated the potential of consumer-grade cameras as a photogrammetric utility data acquisition tool. However, statistical insights from the photogrammetric calibration show that caution needs to be taken about the camera types particularly for lens calibration. Results from the second part of the study were recommended as easy-to-understand guidelines for image acquisition at trenches and supported the planning of photogrammetric measurements in the field.
