ColorImagePoint in openni

[Salvatore Russo]

hi, what is the equivalent funtion in openni to colorImagepoint of microsoft sdk? i saw that it return a X and Y value. but i don't understand how to obtain the same thing in openni. 

thanks in advance!!

You don't have that function in OpenNI. 

You can get metadata array from color image and get R, G and B value.

Please clarify.

You need a function that (given a RGB color) returns the coordinates

of the pixels of that color? Is it right?

yes, i have to obtain the xy coordinates of a single color image point. 

my aim is to reply the exact result that i would obtain using microsoft sdk  ColorImagePoint

here's the link to the specification of the function

i think the closest one is ConvertRealWorldToProjective (XnUInt32
nCount, const XnPoint3D aRealWorld[], XnPoint3D aProjective[])
it does it on the depthmap but if you are using the two images at the
same resolution it works.

You want to find the coordinates of a point with that color, right?

Well, I wonder why would you want to do that?

Normally, you already have the coordinates.

Besides, there will (surely) be other points with that color.

Anyway, you can easily iterate on every pixel and check its color.
