AI总结:

提出WildBox数据集,含23.7万3D框标注,评估两种开放词汇单目3D架构,发现零样本3D检测失败,微调后恢复性能,深度估计是主要瓶颈。

摘要:

我们介绍了WildBox,一个用于从无人机视频中进行野生动物单目3D检测的数据集和基准,包含237,505个3D边界框标注,涵盖七种非洲稀树草原物种,分为六个基准类别。标注采用KITTI/Omni3D兼容格式,位于每个片段尺度归一化的相机坐标系中,并在每个片段内保持实例身份。我们在零样本、真实2D框提示和监督微调协议下评估了两种开放词汇单目3D架构:OVMono3D-LIFT和DetAny3D。开放词汇2D基础模型提供了可用的零样本野生动物定位(50.55 AP@50),但零样本3D检测在所有测试的2D输入条件下(包括真实2D框提示)均崩溃为0.00 AP,从而将失败隔离到3D阶段。在WildBox上微调将性能恢复到8.68 +/- 0.47 AP-BEV@0.50和13.17 +/- 0.69 AP3D宏平均。微调后深度贡献了归一化Hausdorff距离的84%,在零样本中超过99%,将单目航拍深度识别为该场景下的主要开放问题。一种由粗到精的课程学习(即在合并的斑马类别上预训练,然后在细纹斑马/平原斑马分类上微调)以更少的总计算量提高了宏平均3D性能,在两个斑马子类上增益最大。WildBox随视频级划分、评估代码和基线检查点一起发布,以推动无人机视频中3D野生动物感知的进展。

英文摘要:

We introduce WildBox, a dataset and benchmark for monocular 3D detection of wildlife from drone video, comprising 237,505 3D bounding box annotations across seven African savanna species grouped into six benchmark classes. Annotations follow a KITTI/Omni3D-compatible format in a per-segment scale-normalised camera frame, with instance identities maintained across each segment. We evaluate two open-vocabulary monocular 3D architectures, OVMono3D-LIFT and DetAny3D, under zero-shot, ground-truth 2D box prompt, and supervised fine-tuning protocols. Open-vocabulary 2D foundation models provide usable zero-shot wildlife localisation (50.55 AP@50), but zero-shot 3D detection collapses to 0.00 AP across both architectures and every 2D-input condition tested, including ground-truth 2D box prompts, thus isolating the failure to the 3D stage. Fine-tuning on WildBox recovers performance to 8.68 +/- 0.47 AP-BEV@0.50 and 13.17 +/- 0.69 AP3D macro. Depth contributes 84% of normalised Hausdorff distance after fine-tuning and over 99% in zero-shot, identifying monocular aerial depth as the dominant open problem in this regime. A coarse-to-fine curriculum, i.e. pretraining on a merged zebra class before fine-tuning on the Grevy's/plains split, improves macro 3D performance with less total compute, with the largest gains on the two zebra subclasses. WildBox is released with video-level splits, evaluation code, and baseline checkpoints to enable progress in 3D wildlife perception from drone video.
