Convert an image sequence to a PLY point cloud.
Using pip:
pip install img2ply
If you prefer to install from source code use:
cd img2ply/
python setup.py install
From the command line:
img2ply -h
img2ply [-h] -o PLY -bb BOUNDINGBOX BOUNDINGBOX BOUNDINGBOX
[--depthDirection DEPTHDIRECTION] [--depthInverse DEPTHINVERSE]
[--ignoreAlpha IGNOREALPHA] [--widthSamples WIDTHSAMPLES]
[--heightSamples HEIGHTSAMPLES]
[--maintainAspectRatio MAINTAINASPECTRATIO]
input
input: path to image sequence
-o: output file path
-bb: bounding box of object in x, y, z
--depthDirection: direction in which the slices are facing
--depthInverse: reverse the placement of the slices
--ignoreAlpha: ignore pixels with an alpha value below 25
--widthSamples: amount of width samples, if 0 every pixel is sampled
--heightSamples: amount of height samples, if 0 every pixel is sampled
--maintainAspectRatio: maintain aspect ratio of sample points
The package can also be used as a library:
import img2ply
img2ply.convert(
input,
ply,
bb,
direction="z",
inverse=False,
ignoreAlpha=True,
wSamples=0,
hSamples=0,
maintainAspectRatio=True
)Test conversion can be done by running the following code, it will loop over all of the images in the images directory and create a pumpkin.ply file.
cd img2ply/tests
