These programs generate and decode structured light.
Currently supports
- Numpy
pip install git+https://github.com/elerac/structuredlightimport structuredlight as sl
width = 640
height = 480
gray = sl.Gray()
imlist_pattern = gray.generate((width, height))
# Projecting patterns from a projector (or display) and capture images
imlist_captured = imlist_pattern
img_index = gray.decode(imlist_captured, thresh=127)
print(img_index)
# [[ 0 1 2 ... 637 638 639]
# [ 0 1 2 ... 637 638 639]

# [ 0 1 2 ... 637 638 639]]
binary = sl.Binary()
imlist = binary.generate((width, height))
img_index = binary.decode(imlist, thresh=127)
gray = sl.Gray()
imlist = gray.generate((width, height))
img_index = gray.decode(imlist, thresh=127)
xor = sl.XOR(index_last=-1)
imlist = xor.generate((width, height))
img_index = xor.decode(imlist, thresh=127)
ramp = sl.Ramp()
imlist = ramp.generate((width, height))
img_index = ramp.decode(imlist)
phaseshifting = sl.PhaseShifting(num=3)
imlist = phaseshifting.generate((width, height))
img_index = phaseshifting.decode(imlist)
stripe = sl.Stripe()
imlist = stripe.generate((width, height))
img_index = stripe.decode(imlist)Some of the code (Binary, Gray, XOR, ...) needs to binarize. This program provides three methods. See the wiki for details.
When you use structured light, you'll need a full screen display from a projector or display. Here is a program to display the image in full screen.
