This is an implementation of Sea-Thru. The original paper by Derya Akkaynak and Tali Treibitz can be found here. Data can be found here.
You will need python3 as well as all the packages in the requirements.txt file, as well as tkinter (on Ubuntu, sudo apt install python3-tk).
I extended their method to use a CNN-based monocular depth estimation technique called monodepth2, which can be found here. Check out the report for more information!
Example:
# install the requirements
pip3 install -r requirements.txt
# download the dataset
wget "https://www.dropbox.com/sh/xtimf7qwfak4wwc/AAAGqn2JMe98II9lYeBTVBE2a/D3?dl=1"
unzip D3.zip
# generate the image
python3 seathru.py --image Raw/T_S04858.ARW --depth-map depthMaps/depthT_S04858.tif
## If you want to run the monocular depth estimation pipeline
# install deps
git submodule update --init --recursive
python3 seathru-mono-e2e.py --monodepth-add-depth 1.0 --monodepth-multiply-depth 3.0 --image Raw/T_S04858.ARW --raw --output output-monodepth.png
Input:
Output:
Output with estimated depths (ranging from 1.0-4.0 meters):
The monodepth pipeline can also be used with PNG/JPEG images by omitting the --raw option. For each image, the --monodepth-add-depth parameter controls the minimum depth
that the estimation will output, and the --monodepth-multiply-depth controls the range of depths as follows:
output_depths = monodepth_multiply_depth + (monodepth_multiply_depth * monodepth_depths)
where monodepth_depths range from 0 to 1.
