[SOLVED] how to convert the annotation.xml files into train.txt and val.txt for object detection?

how to convert the annotation.xml files into train.txt and val.txt for object detection?

I'm training custom image data sets for object detection using caffe. Here i have train and validation directory. By using LabelImg , the object annotation created in a .xml file for each image separately (image1.xml,image2.xml etc.). Now i want to convert all this xml files into train.txt and val.txt. How can i do it? I stuck in this step since 3 weeks

218.xml

`<annotation>
    <folder>train</folder>
    <filename>218</filename>
    <path>C:\kp\images\train\218.jpg</path>
    <source>
        <database>Unknown</database>
    </source>
    <size>
        <width>352</width>
        <height>288</height>
        <depth>3</depth>
    </size>
    <segmented>0</segmented>
    <object>
        <name>person</name>
        <pose>Unspecified</pose>
        <truncated>0</truncated>
        <difficult>0</difficult>
        <bndbox>
            <xmin>79</xmin>
            <ymin>56</ymin>
            <xmax>262</xmax>
            <ymax>283</ymax>
        </bndbox>
    </object>
</annotation>`

For each image i have created annotation.xml file (image_name.xml) by using the tool. Now i need to convert it into train.txt and val.txt for input to the create LMDB. I have already gone through Caffe LMDB train and val.txt , how to make train.txt file in caffe , A guide to convert_imageset.cpp , https://github.com/chuanqi305/MobileNet-SSD/issues/90

But everything is for object classification and and others didn't explain it too.. Any suggestions or help will be appreciated

Solution

train.txt

imagepath xmlpath

image/image1.jpg label/image1.xml
image/image2.jpg label/image2.xml
image/image3.jpg label/image3.xml
image/image4.jpg label/image4.xml
...

this is train.txt or test.txt
