如何从多维数组中挑选出一些值,然后计算平均选定值?因此,当我点击一些图像时,它应该不仅在鼠标指针所在的位置显示深度数据(来自Microsoft Kinect),还应该计算环境中的值(这是多维数组)。Sum多维数组C#
这是我的代码:
protected void imageIR_MouseClick(object sender, System.Windows.Input.MouseEventArgs e)
{
// Get the x and y coordinates of the mouse pointer.
System.Windows.Point mousePoint = e.GetPosition(imageIR);
double xpos_IR = mousePoint.X;
double ypos_IR = mousePoint.Y;
int x = (int)xpos_IR;
int y = (int)ypos_IR;
lbCoord.Content = "x- & y- Koordinate [pixel]: " + x + " ; " + y;
int d = (ushort)pixelData[x + y * this.depthFrame.Width];
d = d >> 3;
int xpos_Content = (int)((x - 320) * 0.03501/2 * d/10);
int ypos_Content = (int)((240 - y) * 0.03501/2 * d/10);
xpos.Content = "x- Koordinate [mm]: " + xpos_Content;
ypos.Content = "y- Koordinate [mm]: " + ypos_Content;
zpos.Content = "z- Koordinate [mm]: " + (d);
// Allocating array size
int i = 10;
int[] x_array = new int[i];
int[] y_array = new int[i];
int[,] d_array = new int[i,i];
for (int m = 0; m < 10; m++)
{
for (int n = 0; n < 10; n++)
{
x_array[m] = x + m;
y_array[n] = y + n;
d_array[m, n] = (ushort)pixelData[x_array[m] + y_array[n] * this.depthFrame.Width];
d_array[m, n] = d_array[m, n] >> 3;
}
}
}
所以,第一:我怎么总结从d_array所有值[M,N]?是否可以计算每一行的总和( - >一维数组/矢量),然后再次计算列的总和( - >零维数组/标量)?
你可以使用这个帖子中的答案扁平化多维数组http://stackoverflow.com/questions/1590723/flatten-list-in-linq。你可以使用linq来计算平均值以及http://csharp.net-tutorials.org/linq-to-objects/linq-average/csharp-c-linq-average-example/。 –
您可以在锯齿阵列上选择“SelectMany”,而不是多维阵列。 –
