opencv 自带标定程序中有一段代码看不懂，请问老兵是什么意思？

Question

" \nexample command line for calibration from a live feed.\n"
" calibration -w 4 -h 5 -s 0.025 -o camera.yml -op -oe\n"
" \n"
" example command line for calibration from a list of stored images:\n"
" imagelist_creator image_list.xml *.png\n"
" calibration -w 4 -h 5 -s 0.025 -o camera.yml -op -oe image_list.xml\n"
" where image_list.xml is the standard OpenCV XML/YAML\n"
" use imagelist_creator to create the xml or yaml list\n"
" file consisting of the list of strings, e.g.:\n"
" \n"
"<?xml version=\"1.0\"?>\n"
"\n"
"\n"
"view000.png\n"
"view001.png\n"
"<!-- view002.png -->\n"
"view003.png\n"
"view010.png\n"
"one_extra_view.jpg\n"
"\n"
"\n";
请问这些代码是什么意思，是需要准备xml吗？然后还有照片，另外这些照片放在什么位置，因为是标定，只需要这么少的照片吗

这个应该是个yml吧，就是标定程序的一些参数，你标定肯定得用棋盘图像么，按照文件中的命名放好就行了
