使用opencv使用type_id opencv-image读取xml文件 [英] Read xml file with type_id opencv-image using opencv

问题描述

嘿，我在尝试使用type_id"opencv-image"读取xml文件时尝试了很多搜索，我在这里看到的只是"opencv-matrix"，所有可用的帮助对我来说都是无用的. 请帮助我从xml文件读取图像矩阵.

Hey i have tried a lot search in reading xml file with type_id "opencv-image", all i am looking here is "opencv-matrix" and all help available is useless for me. Please help me out in reading an image matrix from xml file.

出于某些想法，我在这里粘贴了xml文件的上半部分.

I am pasting here an upper portion of my xml file for some idea.

</depthImg190>
</opencv_storage>

我已经使用了代码

FileStorage f;
Mat m;
f.open("temp.xml", FileStorage::READ);
f["depthImg190"] >> m;
f.release();

但是我正面临一个异常"Opencv错误:错误的参数<未知数组类型>在cv :: read中，文件........ \ opencv \ modules \ core \ persistence.cpp，第5535行"

but i am facing an exception "Opencv Errorr: Bad argument < Unknown array type > in cv::read, file ........\opencv\modules\core\persistence.cpp, line 5535".

任何帮助都会被申请

推荐答案

实际上，您可以使用一些文档，例如:

Actually there is some documentation that you could use like: http://docs.opencv.org/modules/core/doc/xml_yaml_persistence.html

无论如何，解决问题的方法都很简单:

In any case the answer to your problem is easy:

FileStorage fs("file.xml", FileStorage::READ);
Mat image;

fs["depthImg190"] >> image;

(...)

fs.release();

应该可以！
