The implementation of the methodology and the access datasets are mentioned below:
- A refined CityGML LoD3 model is used. The modelling are done in SketchUP using plugin CityEditor.
- The CityGML LoD2 models are available from LDBV Bavaria.
- Data integration, transformation and visualization are done in FME
- Programming and computation is performed using MATLAB
- Mobile laserscanner pointcloud datasets are recorded by Fraunhofer IOSB in 2016.
- Data pre-processing is mostly performed in FME. Building models and point clouds are accurately georeferenced and reprojected to standard coordinate systems, wherever necessary. Heavy point clouds are downsampled to reduce the size. Point cloud filetypes are changed using CloudCompare/FME. Some clipping of point clouds are done in MATLAB/FME.
- Mask extraction and applying texture image to facade is done in SketchUp.
- MATLAB is used for:
- Thermal mapping algorithm
- Post-processing the generated texture image: Brighten and apply heat map to the image and then blended with the mask.
- Special acknowledgements to Jingwei Zhu for providing the thermal point clouds.
