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

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?

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.
