Question

因此对于我正在研究的这个项目，我有2张照片。这两张照片需要拼接在一起，一张在顶部，一张在底部，然后你就可以看到整个画面了。关于我应该用什么模块来做这个的任何想法？

Answer 1

请参阅tutorial特别是“剪切，粘贴和合并图像”部分以获取相关帮助。

对于粗略轮廓，使用Image.open加载两个图像，使用size属性找出输出图像的大小，并添加一些，使用Image.new创建输出图像，然后使用paste方法过去两个原始图像。

Answer 2

这是使用Pillow的代码示例。希望它可以帮助别人！

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

Answer 3

这是Jan Erik Solems计算机视觉与python书的一些代码;您可以编辑它以满足您的最高/最低需求

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)

Answer 4

根据要图像彼此相邻还是位于顶部，使用numpy.hstack（）或numpy.vstack（）。如果图像是numpy不接受的某种奇怪格式，则可以将其转换为numpy数组。如果使用np.asarray（）方法将图像解释为数组，请确保设置dtype = np.uint8。

我像这样进行垂直缝合-这与@ 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

19-22行-仅高度会改变以进行缝合

在第28行上粘贴第二张图片box=(width1, 0)更改为box=(0, height1)

一起拼接照片
