VGI3D: an Interactive and Low-Cost Solution for 3D Building Modelling from Street-Level VGI Images [PDF]
Journal of Geovisualization and Spatial Analysis, 2021 Applications in smart cities are inseparable from the usage of three-dimensional (3D) building models. However, the cost of generating and constructing 3D building models with semantic information is high both in time and in labour. To solve this problem,
