What are the processes and related software for creating 3D white models in batches from stereoscopic satellite images?

The process of creating a 3D model from a batch of stereoscopic satellite images, also known as "stereophotogrammetry", usually includes several steps and may involve the use of various software. The following is an overview of this process:

Image acquisition: obtain high-resolution stereo satellite images of the region of interest.

Image preprocessing: image correction (such as radiation correction and geometric correction) is carried out to improve image quality.

Stereo matching: Realize stereo matching algorithm, and generate dense digital surface model (DSM) and digital terrain model (DTM) from stereo images.

Ortho-rectification: Ortho-rectification is carried out on the image by using DTM to correct the terrain deformation.

3D feature extraction: 3D features such as buildings, roads and vegetation are extracted from DSM.

3D modeling: Use the extracted data to create a 3D model of the feature.

The specific software that may be used in each step of the process will depend on the specific requirements of the data source and the project. However, frequently used software includes:

Image acquisition software: WorldView, Pleiades, GeoEye, etc.

Image preprocessing software: ENVI, PCI Geomatica, etc.

Stereo matching software: Agisoft Photocan, Pix4D, etc.

Orthophoto correction software: ERDAS Imagine, ArcGIS, etc.

3D feature extraction software: ArcGIS, global mapper, etc.

3 d modeling software: SketchUp, Rhino, AutoCAD, etc.
