Google Tango: Aligning Depth and Color Frames

Question

I would like to align a (synchronous) depth/color frame pair, using the Google Tango tablet, such that, assuming that both frames have the same resolution, each pixel in the

Answer 1

Generating simple crude UV coordinates to map tango point cloud points back onto source image (texture coordinates) - see comments above for more details, we've messed this thread up but good :-( (Language is C#, classes are .Net) Field of view calculate FOV horizontal (true) or vertical (false)

public PointF PictureUV(Vector3D imagePlaneLocation)
        {
            // u is a function of x where y is 0
            double u = Math.Atan2(imagePlaneLocation.X, imagePlaneLocation.Z);
            u += (FieldOfView(true) / 2.0);
            u = u/FieldOfView(true);
            double v = Math.Atan2(imagePlaneLocation.Y, imagePlaneLocation.Z);
            v += (FieldOfView() / 2.0);
            v = v / FieldOfView();

            return new PointF((float)u, (float)(1.0 - v));
        }
