  9. # === 思路 ===
  10. # 核心:每次落稳之后截图,根据截图算出棋子的坐标和下一个块顶面的中点坐标,
  11. # 根据两个点的距离乘以一个时间系数获得长按的时间
  12. # 识别棋子:靠棋子的颜色来识别位置,通过截图发现最下面一行大概是一条直线,就从上往下一行一行遍历,
  13. # 比较颜色(颜色用了一个区间来比较)找到最下面的那一行的所有点,然后求个中点,
  14. # 求好之后再让 Y 轴坐标减小棋子底盘的一半高度从而得到中心点的坐标
  15. # 识别棋盘:靠底色和方块的色差来做,从分数之下的位置开始,一行一行扫描,由于圆形的块最顶上是一条线,
  16. # 方形的上面大概是一个点,所以就用类似识别棋子的做法多识别了几个点求中点,
  17. # 这时候得到了块中点的 X 轴坐标,这时候假设现在棋子在当前块的中心,
  18. # 根据一个通过截图获取的固定的角度来推出中点的 Y 坐标
  19. # 最后:根据两点的坐标算距离乘以系数来获取长按时间(似乎可以直接用 X 轴距离)
  20. # TODO: 解决定位偏移的问题
  21. # TODO: 看看两个块中心到中轴距离是否相同,如果是的话靠这个来判断一下当前超前还是落后,便于矫正
  22. # TODO: 一些固定值根据截图的具体大小计算
  23. # TODO: 直接用 X 轴距离简化逻辑
