全景影像与全景球面的关系

代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace CoordinateTransform
{
    /// <summary>
    /// 像素（影像）坐标转换
    /// </summary>
    public class PixelCoordinateTransform
    {
        /// <summary>
        /// 全景图像像素坐标转为空间直角坐标（半径为1的基础上推算）
        /// </summary>
        /// <param name="W"></param>
        /// <param name="H"></param>
        /// <param name="x"></param>
        /// <param name="y"></param>
        /// <returns></returns>
        public static Point3D PixelToSpaceRectangularCoordinate_r1(double W, double H, double x, double y)
        {
            double r = 1;
            double fai_h = (Math.PI * (W - 2 * x)) / W;
            double fai_gama = (Math.PI * (H - 2 * y)) / (2 * H);

            double fai_h_ = fai_h * 180 / Math.PI;
            double fai_gama_ = fai_gama * 180 / Math.PI;

            double x1 = r * Math.Cos(fai_gama) * Math.Cos(fai_h);
            double y1 = r * Math.Cos(fai_gama) * Math.Sin(fai_h);
            double z1 = r * Math.Sin(fai_gama);

            return new Point3D(x1, y1, z1);
        }



    }
}
