Question

我有一个立体图像的深度图女巫被保存为xml文件，我想从这个文件中提取2D浮点数并将其保存为浮动图像，我解决了我的请求的第二部分女巫正在保存2D数组作为浮动图像成功，我搜索了相关的答案，但我没有找到，所以有人会帮我吗？我的XML文件看起来与此类似：


?xml version="1.0"?

opencv_storage

depth type_id="opencv-matrix"

   rows 480 /rows

   cols 640 /cols

   dt f /dt

   data

我已解决了以下问题：

from PIL import Image
import cv2

cv_file = cv2.FileStorage("test.xml", cv2.FILE_STORAGE_READ)       % reading my xml file as a storage file
             matrix = cv_file.getNode("depth").mat()               % getting the node of the 2D array named "depth" as shown in the  above xml file.
             img1 = Image.fromarray(matrix)                        % reading the 2D array as an image
             img1.save(dest, "tiff")                               % saving the image with a tiff format

使用python从XML文件中提取2D数组数据
