Question

非常感谢您做的这份无私的工作！接下来我向您请教一些我在进行多目标追踪标注时遇到的问题：
我使用的最新的CPU版本来进行标注

我使用了自定义的模型成功对视频的每一帧进行了检测和追踪

并且在进行导出MOT标注时也显示没问题

但是最后生成了MOT文件夹里，gt和det文件都是空的

Hi @lyg-del, thanks so much for your kind words and for raising this issue! It's much appreciated. 😊

I've just run some tests on the MOT data export function, and it appears to be working correctly on our end. A key point to note is that currently, MOT data export only supports standard horizontal bounding box objects (where the shape_type is rectangle). It does not yet support rotated bounding box objects.

You can easily check the object types in your project by pressing Ctrl + G in the GUI – this will display your current object statistics, which should help you identify if you're using rotated boxes.

For a more detailed explanation and guidance on MOT labeling, please refer to the official user manual here

I hope this helps clarify why your gt and det files might be empty! Please let us know if you have any more questions. 🙏

感谢您的回复和解答，我确实是想导出旋转框的MOT文件。
