Using Stereo Images from an Imaging Total Station to Autonomously Produce 3D Real World Coordinates

Biviano, Jordan James (2017) Using Stereo Images from an Imaging Total Station to Autonomously Produce 3D Real World Coordinates. [USQ Project]


Detail surveys of buildings and structures is a common task for a surveyor, improving the efficiency on these tasks is fundamental requirement for the industries growth. Investigation into the ‘Vision Technology’ of Trimble’s S7 Imaging Total Station was found to be considerably limited. Utilising the photogrammetry function in the instrument by taking a photo with the camera requires surveyed points attached with the images. If no surveyed points exist, the images would not have a georeferenced position. Therefore, when imported into Trimble Business Centre to select objects in the images for a three dimensional coordinate, the software cannot reference or scale the image to its position. By taking surveyed points in the field reduces the requirement and efficiency of the photogrammetry method. The fact photogrammetry software packages are expensive, and not tailored to provide a quick output of coordinates from an Imaging Total Station provided further importance of this research. This research focused on depicting how to reconstruct images from the instrument without needing any surveyed points. Through successfully completing this, it was fundamental to automate the process through developing an algorithm code in MATLAB. The program needed to produce three dimensional coordinates in a CSV file format from any two images taken with the S7 Imaging Total Station. A methodology was developed through selecting a building facade to base the testing off. A survey accurate model of points spread throughout the total image overlap space with accurate X,Y,Z were captured to compare against points selected in the MATLAB program. The analysis identified the coordinates generated through the MATLAB program to be at a similar level of accuracy to traditional survey methodology. However, variation in accuracy depends on the projection distance. In conclusion, a successful program was developed to generate three dimensional coordinates from an S7 Imaging Total Station without control points in the images. This program can now be implemented into any practical survey situation, and can save time, costs and increase safety.
