C# 图像检测优化

我正在写一个脚本来自动化游戏中无聊的部分。基本上，我有一个多玩家可以使用的游戏不同部分的复选框。如果勾选了复选框，则脚本将截图，如果位置可用，则我的角色可以单击该位置并在其他玩家之前跳到该特定位置，如图1所示

现在，我的角色最多可以访问18个可能的位置（只要另一个角色不在那里）。如果我选中了所有18个框，那么我的脚本将开始运行所有18个位置，直到找到一个打开的位置。它基本上由图1的复制/粘贴表示，但在图2中进行了调整

我有一个计时器，每5秒启动一次，检查屏幕是否已更改，以检查是否需要采取行动。然而，它没有使用大量的CPU/内存，有时它会停止响应，这是不好的。此外，每5秒（即执行屏幕检查时），电源使用量就会跳到非常高的水平。我如何优化它，使其更有效？是否有更好的方法检查屏幕更改

尝试使用后台工作程序。当您在与UI相同的线程上运行计算时，会产生瓶颈，导致UI冻结，有时还会执行其他奇怪的操作。这里有一个可能有用的链接。

您认为使用后台工作程序（1个用于UI，1个用于执行图像检测和if语句）可以防止UI锁定吗？它对系统资源有什么作用？不，用户界面不需要后台工作程序。我建议通过后台工作程序执行图像检测代码。UI已经在线程上运行。通过使用后台工作程序，您可以在单独的线程上执行图像检测代码。这将有望解决滞后问题。
