1.前言
大家常用labelimg标注物体,但当目标物体是倾斜角度时,labelimg标注时会把不属于物体的一大片区域也标注,这样标注效果不大好,那么有什么工具可以标注倾斜的矩形框呢,本篇通过介绍安装rolabelimg或者labelimg2(这两个除了UI界面不同,操作起来都一样),来解决该问题。
安装
2.安装
1.安装labelimg
要装rolabelimg要先装labelimg

2.安装rolabelimg或者labelimg2
去github下载项目
rolabelimg

4.操作快捷键
5.数据格式
labelimg2的格式

roLabelImg的格式

roLabelImg比labelimg2的数据也就多了一个参数。
经过测试,rolabelimg无法导入labelimg2和labelimg标注数据。
而labelimg2则可以正常导入其它2种标注工具的标注过的数据。
