The process begins with data acquisition and ends with a fully textured photo-realistic representation of a building. There are numerous image based modelling techniques that can generate visually rich models. However, certain applications or methods are only suitable for visualisation purposes and lack the accuracy to achieve a high level of detail. Furthermore, the achievement of accurate results can be a long process and requires a considerable amount of knowledge of photogrammetric techniques. Therefore, choosing the most appropriate technique is essential. This research presents a method for generating a building model to CityGML LoD3 standard using panoramic imagery captured with Trimble’s V10 Imaging Rover. The aim of this dissertation is to develop a workflow to produce or enhance an existing building model in Prime2 to CityGML LoD3 standard using the Trimble V10 Imaging Rover. This research presents a new approach for generating accurate 3D models. It is divided into four key sections, data acquisition, data processing, data visualisation and data integration and includes a full workflow and an analysis of the different stages and steps involved. The research method provided a fast and effective method to produce a 3D model resulting in a rich geospatial deliverable. It had a high level of geometric accuracy whilst producing a high quality photo realistic model. The approach adopted to integrate the model with existing Prime2 data was both easy to use and offered a high degree of accuracy. From these results, it can be concluded that this study provides an easy method for adding CityGML Level of Detail 3 geometry to the new Prime2 data storage model.
