点云标注数据集文件说明

OCTOPUS格式文件基本要求（点云标注）

上传的OCTOPUS格式数据集需包含以下文件。

.
├─ 时间戳
    ├─ 时间戳.pcd         #该时间戳对应的已标注点云图像
    ├─ cam0-时间戳.jpg    #该时间戳点云图像对应的已标注图片
    ├─ 时间戳.json        #该时间戳内该标注图像的所有标注信息

标注数据.json文件说明

数据集中必含“.json”文件，用以集合该时间戳已标注图片的所有标注数据信息，包括该图片所在的项目id、数据包id、图片上所有标注框信息等。上传数据集前请保证“.json”文件内容正确。您可参考以下样例编写“.json”文件。
