如何使用python cv2打开16位1通道灰度图像

Question

如何使用cv2打开16位1通道灰度图像？我不想转换文件。该文件已经是我需要它的形式。

class Diet < ApplicationRecord
    belongs_to :coach

    has_many :user_eat_diets
    has_many :user, through: :user_eat_diets
    accepts_nested_attributes_for :user_eat_diets

    has_many :diet_composes
    has_many :foods, through: :diet_composes
    accepts_nested_attributes_for :diet_composes
end

我期待1个uint16频道，文件大小应该是2457600
