Abstract
There has been increasing interest in low-cost close range photogrammetry techniques for use in a variety of applications. The use of these techniques in medicine, forensic science, architecture, engineering, archaeology and anthropology to record, measure and monitor objects and sites has been growing in recent years. Close range photogrammetry has been particularly investigated and preferred for human body mapping due to being non-contact, non-invasive, accurate, and inexpensive and data is re-measurable.
Skulls have been traditionally measured using callipers and tape in anthropological study, which is subject to observer error. Close range photogrammetry can be used to perform more accurate measurements and retain a digital copy of the skull, which can be re-used for a number of purposes. Using low cost software (Photomodeler), and low cost cameras, the aim of this project is to detail the camera calibration techniques and image capture of a skull. The process for 3D modelling using close range photogrammetry includes camera calibration to determine the camera’s internal parameters, photographing the object within a control target frame, and processing the data with photogrammetry software.
Achieving a high precision camera calibration and producing a high-accuracy 3D model were more difficult than anticipated. There are a number of factors which can result in a poor quality models. However, the results show that photogrammetry can be utilised in the capture of accurate 3D skull model using low-cost cameras efficiently. The research was successful, the project objectives were satisfied and the accuracy across the project was approximately 0.4mm.
