A Python script for preforming refraction correction on Structure from Motion datasets.

pyBathySfM

Updates to the original py_sfm_depth with a new fancy name and a shiny new GUI interface

Update History

• V.4 - 2019 June 26 - GUI bug fixes

Tutorial - https://geojames.github.io/pyBathySfM/

Updates from the original py_sfm_depth

1. Shiny new GUI interface (QT)
2. More options
   • Angle and distance filters
   • Debugging outputs (raw processing outputs)
   • added small angle refraction calculation option

This script is SfM software indifferent (Agisoft, Pix4D, etc)

• you just need to be able to export a CSV point cloud and get camera parameters (x,y,z,pitch,roll,yaw)
• see the tutorial for more info.

Running the script

Download and unzip the Github Repository to a In your command line program of choice (i.e. Windows command prompt, Anaconda prompt)

• Change the direcotry cd c:\... to the unzipped repository
• Run the script with python pyBathySfM.py
  • do not run pyBathySfM_gui.py this is the source code, but it will not display the GUI

Requirements

• Python v3.x (written in 3.6 & 3.7)
• Required Libraries: PyQT5, numpy, pandas, sympy, matplotlib

** I use Anaconda Python that has all the required libraries

pybathysfm's Issues

Calculation of Visibility Not Working

Good afternoon, Dr. Dietrich.
I am wondering if you could give some enlightenment on this issue I have been facing when using the script for refraction correction.
When I run it for my dataset, the function for visibility calculation returns a empty array, but regardless that, I still can get the calculation of corrected depth.
For another dataset, the output corrected point cloud show some points without the correction calculation. I am trying to figure out why is that, but not success so far. I did check the target points' coordinates and camera coordinates, as well, and they seem ok.
Would you possibly have some idea of the cause for it?

Thank you.

Output Error, missing corElev_avg

Hello, At first thanks for your software.

When I try to use your software, in the output csv the only data I get is h_a, the other columns are empty

Tried your sample data but got the same result.

What could be the problem?
