Download address: link: https://pan.baidu.com/s/1ZVRpMIbkN2HryCtwfOvdMw extraction code: 6666

The downloaded file is a compiled, executable labelImg.exe file. Directly put the file in the windows environment, double-click to execute.

2. How to use labelImg tools:

1. Double-click the labelImg execution file icon, and the operation interface will appear:

The appearance of such a window interface indicates that labelImg has been opened normally, and the window with a black background is the terminal interface, ignore it.

On the left side of the labelImg window, there are some operational functions, among which: "Open" opens a single image, "Open Dir" opens a folder, and "Change Save Dir"

The path where the image is saved, "Next Image" switches to the next image, "Prev Image" switches to the previous image, "Verify Image" check image, "Save"

Save the image, one "Create RectBox" label box, "Duplicate RectBox" repeat label box, "Delete RectBox" delete callout box, "Zoom In"

Enlarge the image, "Zoom Out" reduces the image, "Fit Window" image applies to the window, and "Fit Width" image adapts to the width.

Of course, it is not very convenient to use the operation button, here are some fast shortcut keys to save some time for boring labeling work.

Hotkeys:

Finally, the .xml file is generated under the path where the file is saved. The name of the .xml file is the same as the name of the marked photo. If you want to modify it, it has already been marked.

The information in the .xml will also change accordingly. The format used by xml and PASCAL VOC is the same!
