Accurate 3-D Modelling from DSLR Images for Residential Design Purposes

Burgess, Liam P. (2018) Accurate 3-D Modelling from DSLR Images for Residential Design Purposes. [USQ Project]


This research project aimed to create a 3D model of an average suburban backyard suitable for an architect to design additions and alterations to an existing property using close range photogrammetry survey methods and analyse it for accuracy, time and cost efficiency.

It has been identified that an alternative method for capturing and modelling data to reconstruct a 3D model suitable for designs is required since conventional and state of the art survey methods for this data capturing is seen as overly expensive by the general consumer and is not profitable to the surveyor which can lead to incomplete surveys and loss of professional confidence by the general public.

In researching this project, it has become evident that there is very little research about an entire scene. However, significant papers and journals have completed research using close range photogrammetry survey methods to capture archaeological artefacts, monuments and building facades.

This research project has identified the key to image registrations is the use of targets that are captured in multiple images. The other important research findings were the key three rules of photogrammetry, overlap, sharpness, and consistency, and the exposure triangle which consists of aperture, ISO setting, and shutter speed, and these ensure the best quality images are captured and will ensure the scene is captured adequately for modelling.

Three close range photogrammetry surveys were conducted to compare the outcomes with varying numbers of images using one and two different capturing techniques, parallel axis and convergent axis capturing against the conventional and state of the art surveys. The final close range photogrammetry models would be compared for accuracy regarding point position and feature dimensions and for time and cost efficiency with the known survey methods.

The major findings this research has achieved is that a 3D model can be created using close range photogrammetry survey methods that can compete with the accuracies achieved by conventional and state of the art survey methods and can reduce the cost to the consumer whilst making the survey more profitable to the surveyor, ensuring professional confidence is maintained with accurate data whilst being cost and time efficient.
