A novel approach for constructing a 3D model based on registering a mono image on a 3D model, applicable in Digital Earth

Abstract

The effect of Digital Earth on our life is vital. Developing and updating Geospatial data in Digital Earth is also essential. This paper presents the application of a new approach of image registration in Digital Earth. The approach was developed based on registering a mono photograph on a master 3D model. The result is a 3D vector model, which can be broadly applied in visualisation, mapping, geographic information system (GIS), planning, change detection, as well as Digital Earth. The approach does not require parameters of correction for transformation. The accuracy of the output depends on the accuracy of the master data. This approach is very versatile and able to register any image on the digital elevation model, digital surface model and topographic 3D model.

New Approach for Object Detection and Extraction from Digital Images for Providing a 3D Model Applicable in 3D GIS

“…In this step the extracted data from the aerial image is transferred and registered on the preliminary 3D model. The aim of this step is to convert all pixels to points whose attributes are X, Y, Z coordinates that are taken from point the cloud data, and colour information that is inherited from aerial image as explained by (Homainejad 2012, Homainejad 2011. Basically, the output in this step is new point cloud data.…”
