The process of creating a 3D model from a batch of stereo satellite images, also known as "stereophotogrammetry", usually involves several steps and may involve the use of various software. Here is a general overview of the process:
Image Acquisition: Acquiring high-resolution stereo satellite imagery of the area of interest.
Image preprocessing: Perform image corrections (e.g., radiometric and geometric corrections) to improve image quality.
Stereo Matching: Performs stereo matching algorithms to generate dense digital surface models (DSMs) and digital terrain models (DTMs) from stereo images.
Ortho-Correction: Ortho-corrects the image using the DTM to correct for terrain distortion.
3D Feature Extraction: Extracts 3D features such as buildings, roads, and vegetation from the DSM.
3D Modeling: Use the extracted data to create 3D models of features.
The specific software that may be used in each step of the process will depend on the data source and the specific requirements of the project. However, frequently used software includes:
Image acquisition software: WorldView, Pleiades, GeoEye, and others.
Image preprocessing software: ENVI, PCI Geomatica, etc.
Stereo matching software: Agisoft Photocan, Pix4D, etc.
Orthographic correction software: ERDAS Imagine, ArcGIS, etc.
Software for 3D feature extraction: ArcGIS, Global Mapper, etc.
Software for 3D modeling: SketchUp, Rhino, AutoCAD, and so on.
