How do I properly convert the pixel rgb values in a picture I have taken to th XY values needed to to send to the Phillips Hue device? My current code does the following: 1:Take a picture, find the most common colors. 2:Cycle throw them and then take another picture. 3:Send the value to a Phillips Hue Bulbs. If you need more of the code, do tell, I can share everything if it helps. I am particularly confused here as the conversion in colormath gives me an xyz and not just an xy. And if I give the converstion of rbg(0,0,0) it gives a while color on the hue bulb.
from beautifulhue.api import Bridge
from colormath.color_objects import RGBColor
from time import sleep
while True:
from pprint import pprint
color_set = colors_from_cam()
pprint(color_set)
for item in color_set:
print "Getting the color"
pprint(item)
time_length = item[0] # prominence
red, green, blue = item[1] # colors
#Set a lights attributes based on RGB colors.
rgb_color = RGBColor(red,green,blue)
xyz_color = rgb_color.convert_to('xyz', target_rgb='cie_rgb')
xyz_x = xyz_color.xyz_x
xyz_y = xyz_color.xyz_y
xyz_z = xyz_color.xyz_z
resource = {
'which':3,
'data':{
'state':{'on':True,
'xy':[xyz_x, xyz_y],
'transitiontime': 1,
'bri': 255}
}
}
bridge.light.update(resource)
print "sleeping"
sleep(1)
sleep(2)
print "taking another picture."
