Sau khi kiểm tra chạy lại thì kết quả chạy trả lại kết quả lỗi tại 

var Point = KAutoHelper.ImageScanOpenCV.FindOutPoint(manhinh, anh);
                if (Point != null)
                {
                    KAutoHelper.ADBHelper.Tap(deviceID, Point.Value.X, Point.Value.Y);
                    chay = 11;
                    manhinh.Dispose();
                    Point = null;
                    if (IsStop)
                        break;
                }

......

Và chương trình thông báo lỗi như sau:

emgu.cv.util.cvexception 'opencv u != 0'

Theo mình nghĩ do bộ nhớ đã chiếm quá nhiều tài nguyên, còn nguyên nhân cụ thể thì mình không biết, có lẽ là liên quan đến kiến thức của môn kiến trúc máy tính, bạn nên tìm hiểu lại môn này để biết nguyên nhân cụ thể là gì nha! Chúc bạn thành công!
