所以对于我正在进行的这个项目，我有 2 张照片。这两张照片需要拼接在一起，一张在上面，一张在下面，然后你就可以看到整个画面了。关于我应该使用哪个模块来执行此操作的任何想法？

这是使用Pillow的代码示例。希望它可以帮助某人！

from PIL import Image

def merge_images(file1, file2):
    """Merge two images into one, displayed side by side
    :param file1: path to first image file
    :param file2: path to second image file
    :return: the merged Image object
    """
    image1 = Image.open(file1)
    image2 = Image.open(file2)

    (width1, height1) = image1.size
    (width2, height2) = image2.size

    result_width = width1 + width2
    result_height = max(height1, height2)

    result = Image.new('RGB', (result_width, result_height))
    result.paste(im=image1, box=(0, 0))
    result.paste(im=image2, box=(width1, 0))
    return result

python 成像库（更新的链接）将在早餐时吃掉该任务。

请参阅教程，特别是“剪切、粘贴和合并图像”部分以获得一些相关帮助。

对于粗略的轮廓，使用 加载两个图像，通过使用属性和一些添加Image.open找出输出图像的大小，创建输出图像，然后使用方法将两个原始图像过去。sizeImage.newpaste

这是来自 Jan Erik Solems 计算机视觉与 Python 书籍的一些代码；您可能可以对其进行编辑以适合您的顶部/底部需求

def stitchImages(im1,im2):
    '''Takes 2 PIL Images and returns a new image that 
    appends the two images side-by-side. '''

    # select the image with the fewest rows and fill in enough empty rows
    rows1 = im1.shape[0]    
    rows2 = im2.shape[0]

    if rows1 < rows2:
        im1 = concatenate((im1,zeros((rows2-rows1,im1.shape[1]))), axis=0)
    elif rows1 > rows2:
        im2 = concatenate((im2,zeros((rows1-rows2,im2.shape[1]))), axis=0)
    # if none of these cases they are equal, no filling needed.

    return concatenate((im1,im2), axis=1)

使用numpy.hstack()或numpy.vstack()基于您是否希望图像彼此相邻或彼此重叠。如果图像是 numpy 不接受的奇怪格式，您可以将它们转换为 numpy 数组。确保设置dtype=np.uint8是否使用该np.asarray()方法将图像解释为数组。

我做了这样的垂直拼接 - 它与@d3ming 的代码相同

07: def merge_images(file1, file2):
08:     """Merge two images into one vertical image
09:     :param file1: path to first image file
10:     :param file2: path to second image file
11:     :return: the merged Image object
12:     """
13:     image1 = Image.open(file1)
14:     image2 = Image.open(file2)
15: 
16:     (width1, height1) = image1.size
17:     (width2, height2) = image2.size
18: 
19:     # result_width = width1 + width2
20:     result_width = width1
21:     # result_height = max(height1, height2)
22:     result_height = height1 + height2
23: 
24:     print (height2)
25: 
26:     result = Image.new('RGB', (result_width, result_height))
27:     result.paste(im=image1, box=(0, 0))
28:     result.paste(im=image2, box=(0, height1))
29:     return result

第 19-22 行 - 只有高度会改变拼接

box=(width1, 0)将第 28 行更改为的第二张图片粘贴到box=(0, height1)
