Installation

Complete bob’s installation instructions. Then, to install this package, run:

$ conda install bob.ip.stereo

Example

Here is an example of how to use the package to load data recorded with 3 different cameras, build a depth map using 2 of them and use it to project the third camera’s data.

# Import Stream and StreamFile classes
# Generic processing filters are available through the Stream class
from bob.io.stream import StreamFile, Stream

# Import bob.ip.stereo: this updates the Stream class with the stereo filters
# It also upates the StreamFile class to allow to set camera configuration information.

f = StreamFile(
   resource_path("test/data/input_example.h5", "bob.io.stream"),
   resource_path("config/idiap_face_streams.json", "bob.io.stream"),
)
f.set_camera_configs(resource_path("config/idiap_face_calibration.json"))

# stream for stereo and projection tests
color = Stream("color", f)
nir_left = Stream("nir_left_stereo", f).adjust(color)
nir_right = Stream("nir_right_stereo", f).adjust(color)

# reproject operations
map_3d = nir_left.stereo(nir_right)
depth = map_3d.select(channel=2).colormap(colormap="jet")
rep_color = color.reproject(nir_left, nir_right, map_3d)

# Use the stereo data:
rep_color[0:2]  # ...
