use*_*079 5 java multidimensional-array
代码的目的:识别屏幕上的按钮/自动获取其坐标,无需人工干预。(该代码应该在更大的 2D 数组中找到一个 2D 数组)。
我如何尝试解决这个问题:我将每个 RGB 像素值存储在一个 2D 数组(a[][]也称为大数组)中。我将按钮像素/较小的 2Darray 存储在optionArrayButton[][]. 然后编写这些步骤:(在阅读本文时查看下面的数组)。
SmallerArray[0][0] = firstSmallerArray号码的号码FirstSmallerArray通过遍历[0][0]到[0][end]然后[1][0]到[1][end]等等来检查更大的数组中的数字。firstSmallerArray未找到号码,则返回-1或not Found。smallerArray.length) 和宽度 ( smallerArray[0].length)。firstSmallerArraynumbersmallerArray.length和smallerArray[0].length存储在临时数组中。temp == smallerArray并获取坐标。我需要帮助:出于某种原因,即使较小的数组位于较大的数组内,它也会说找不到按钮(foundButton 返回 false)。我花了两天时间也没发现问题所在。
因为我使用的数组有超过 200 万个 RGB 值,所以我将直接给出这些数组。更大的数组:
[3 3 1 0 9]
[4 1 5 4 5]
[7 5 6 2 8]
[8 2 7 3 5]
[1 8 7 6 4]

我在编码方面有点菜鸟,所以我可能不会理解 java/编码术语。再次感谢任何可以提供帮助的人。

使用这种方法:
int[][] matrix = ...;
int[][] submatrix = ...;
loopX: for (int x = 0; x < matrix.length - submatrix.length + 1; ++x)
loopY: for (int y = 0; y < matrix[x].length - submatrix[0].length + 1; ++y)
{
for (int xx = 0; xx < submatrix.length; ++xx)
for (int yy = 0; yy < submatrix[0].length; ++yy)
{
if (matrix[x + xx][y + yy] != submatrix[xx][yy])
{
continue loopY;
}
}
// Found the submatrix!
System.out.println("Found at: " + x + " " + y);
break loopX;
}
System.out.println("Done");

你的魔法数字300很可疑。也许您的按钮距离左侧或顶部超过 300 像素?还要确保您使用无损图像。只有 1 位错误,此操作失败。
