Introduction
ANDROMEDE (ANalyse de Données et de Relevés Optiques pour la Mesure de Débit et l’Ecohydraulique) software is a platform for processing videos or images to measure the surface velocities of natural flows. It is based on methods developed at IMFT, for Tractrac or Opyflow software, or directly available in the OpenCV libraries.
The specificity of ANDROMEDE is to propose methods adapted to measurement by drone whether for stabilization, orthorectification from GPS data or the possibility of processing images acquired during movement.
ANDROMEDE is free software (licence GPL) whose development was funded by the French Office for Biodiversity through a project of the ecohydraulic pole OFB/IMFT/PPRIME. The development team is made up of people from the Toulouse Fluid Mechanics Institute and MFEED.
ANDROMEDE is based on image processing tools available in the OpenCV Librairy:
Some of the numerical methods included in ANDROMEDE are derived from existing image analysis tools. ANDROMEDE allows a graphical interface of these tools and a direct use. The original scripts of these methods are available on the following sites:
