WebCIE has also introduced normalized coordinates x, y and z, obtained by dividing the X, Y and Z values by (X + Y + Z). One can then take x and y as chromaticity coordinates, determining color tones for a certain luminance. That system is called CIE xyY, because a color value is defined by the chromaticity coordinates x and y in addition to the ... WebNov 7, 2015 · I have a robot that's effectively able to locate a ball and get x,y coordinates in terms of pixels using a simple RGB camera from the Kinect. I also have a point cloud generated from the same Kinect, where I hope to find the depth perception of the ball using the X,Y coords sent from the circle recognition from my RGB camera.

WebJun 24, 2024 · The derivation of this ultimately comes from knowing that Xr + Xg + Xb = Xw, (meaning the sum of the primaries must equal the white point), and the same for Y and Z. I see you know how to get the tristimulus XYZ from CIE 1931 Yxy values, but for those who don't: xyz from XYZ: x = X / (X + Y + Z) y = Y / (X + Y + Z) z = Z / (X + Y + Z) = 1 - x - y WebMar 27, 2016 · X, Y and Z can be normalized by dividing by their sum (at the expense of losing information about the brightness of the light): x = X X + Y + Z, y = Y X + Y + Z, z = Z X + Y + Z = 1 − x − y. In this way, only two parameters, x and y are needed to describe the colour (more accurately, the chromaticity) of the light.
