DOSOD
功能介绍
DOSOD (Decoupled Open-Set Object Detector)[https://github.com/D-Robotics-AI-Lab/DOSOD] 是地瓜自研的开放词汇目标检测方法，利用输入文本特征进行重参数化，可以实现以零样本的方式更改目标检测类别。此为与常规检测器最大的差别。
代码仓库： (https://github.com/D-Robotics/hobot_dosod)
应用场景：DOSOD强大的零样本检测能力使得其具有更强的泛化能力，可以应用在智能驾驶、智能家居、地质检测等领域。
支持平台
| 平台 | 运行方式 | 示例功能 |
|---|---|---|
| RDK X5 | Ubuntu 22.04 (Humble) | 启动MIPI/USB摄像头/本地回灌，并通过Web展示推理渲染结果 |
准备工作
RDK平台
-
RDK已烧录好Ubuntu 22.04系统镜像。
-
RDK已成功安装TogetheROS.Bot。
