RF-DETR OC-SORT 多目标跟踪实战遮挡场景下的轨迹稳定性优化这篇教程根据我复现 OC-SORT 多目标跟踪流程时整理重点演示快速跟踪、Python 回调处理和复杂运动场景下的轨迹增强。本文整理自我的学习和项目复现过程尽量按实操顺序保留 notebook 的关键步骤同时把数据集获取方式调整为适合中文教程发布的写法。本文会重点跑通以下流程安装跟踪依赖准备示例视频或自己的视频使用 CLI 运行 OC-SORT 跟踪用 Python 组合检测器和 OCSORTTracker结合运动补偿处理镜头运动场景如果你正在系统学习目标检测、实例分割、OCR、多目标跟踪或视觉大模型建议收藏本文配套 notebook、示例图片和运行环境说明后续会继续整理。如果环境配置卡住可以在评论区说明具体报错。 文章目录RF-DETR OC-SORT 多目标跟踪实战遮挡场景下的轨迹稳定性优化⚙️ 环境准备
