The script allows users to align imagery and apply different gradual selection filters to reduce errors in sparse point clouds. Legacy versions of this script which implement a previous version (version 1.0) of the workflow are available in the legacy_scripts directory within this repository. The error reduction technique and sparse point cloud gradual selection filter values were developed with the goal of maintaining the accuracies of traditional photogrammetric processes with newer techniques supported by structure from motion (SfM) based software. The workflow involves the application of gradual selection filters to reduce errors in sparse point clouds, and improve camera lens models and camera position estimates. Geological Survey Open-File Report 2021-1039 (Over et al., 2021). The current version of the script (version 2.0) approximates the workflow described in U.S. Yet, all the processing is performed locally, without transmitting the data outside the company, making it an ideal solution for processing sensitive data.This repository contains python scripts which automate image alignment and sparse point cloud error reduction in the Agisoft Metashape/Photoscan structure from motion photogrammetry software package using the Agisoft Metashape Python API. This program is a stand-alone photogrammetric software solution for automatically generating dense point clouds, textured polygonal models, georeferenced true orthomosaics, and DSMs/DTMs from still images.īased on the state-of-the-art technology developed by Agisoft, Metashape Professional allows for high-speed processing (typically within a couple of hours), providing at the same time highly accurate results (up to 3cm for aerial and up to 1mm for close-range photography).Īgisoft Metashape Professional is capable of processing thousands of photos. Overview of Agisoft Metashape Professional This program can be used for photogrammetric processing of digital images and 3D spatial data generation.
