我想将我现有的 coco 格式转换为 labelme 格式:

可可:

{"info":{"description":"my-project-name"},"images":[{"id":1,"width":3296,"height":2472,"file_name":"test.png"}],"annotations":[{"id":0,"iscrowd":0,"image_id":1,"category_id":1,"segmentation":[[1281.1870967741934,626.5437788018434,1235.6202764976958,726.7907834101383,1383.7124423963132,745.0175115207373,1547.752995391705,726.7907834101383,1595.5981566820276,624.2654377880185]],"bbox":[1235.6202764976958,624.2654377880185,359.97788018433175,120.75207373271883],"area":34552.81165112869},{"id":1,"iscrowd":0,"image_id":1,"category_id":1,"segmentation":[[474.6543778801842,776.9142857142858,460.98433179723486,895.3880184331798,823.2405529953916,870.3262672811061,807.2921658986174,758.6875576036867]],"bbox":[460.98433179723486,758.6875576036867,362.2562211981567,136.70046082949307],"area":40000.595896281506}],"categories":[{"id":1,"name":"leaf"}]}

我不清楚为什么 labelme 将多边形存储为点。如何将我的 coco 多边形列表转换为 labelme 的点多边形列表?

我和我的同学创建了一个名为PyLabel的 python 包来帮助其他人完成此类任务和其他标记任务。您可以在此笔记本中看到一个示例:https ://github.com/pylabel-project/samples/blob/main/coco2voc.ipynb

虽然这可能不会直接转为 labelme 格式,但您应该能够使用包的导入器工具将数据导入数据框,然后您可以使用该数据框将其转换为所需的格式。

如果您有兴趣在其他格式之间进行转换,可以在此处找到该包的代码:https ://github.com/pylabel-project/
