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)。
我是如何尝试解决的: 我将每个RGB像素值存储在一个二维数组中(a[][]
也称为大数组)。我在optionArrayButton[][]
中存储了按钮像素/较小的2D阵列。
然后对这些步骤进行编码:(在阅读时查看下面的数组)。
SmallerArray[0][0] = firstSmallerArray
号码FirstSmallerArray
至[0][0]
然后[0][end]
至[1][0]
检查Biger数组的[1][end]
号码,依此类推。firstSmallerArray
号码,请返回-1
或not Found
。smallerArray.length
)和宽度(smallerArray[0].length
)的高度。firstSmallerArray
号码,smallerArray.length
和smallerArray[0].length
存储。temp == smallerArray
并获取坐标。我需要帮助: 由于某些原因,即使较小的数组位于较大的数组中,也表示找不到按钮(foundButton返回false)。我花了两天时间才发现错误。
因为我使用的数组有200万+ RGB值,所以我只是给这些数组代替。 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]
较小的数组:
[5 6 2]
[2 7 3]
[8 7 6]
我在编码方面有点像菜鸟,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。

答案 0 :(得分:2)
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");
你的幻数300
是可疑的。也许您的按钮距离左侧或顶部超过300像素?还要确保使用无损图像。只有1位错误,这就失败了。
