摘要:

在自动驾驶场景中生成高保真、时间一致的视频面临重大挑战,例如在极端情况下的问题性操作。尽管最近提出的视频生成工作旨在解决上述问题,即基于扩散Transformer(DiT)构建的模型,但仍缺少针对多视角视频生成场景潜力探索的工作。值得注意的是,我们提出了首个基于DiT的框架,专门用于生成时间一致且多视角一致的视频,能够精确匹配给定的鸟瞰图布局控制。具体而言,所提出的框架利用无参数的空间视角膨胀注意力机制来保证跨视角一致性,并集成了联合交叉注意力模块和ControlNet-Transformer以进一步提高控制精度。为了展示我们的优势,我们在nuScenes数据集上广泛进行了定性比较研究,特别是在一些最具挑战性的极端情况中。总之,我们提出的方法在困难条件下生成长时、可控且高度一致的视频的有效性得到了证明。

英文摘要:

Generating high-fidelity, temporally consistent videos in autonomous driving scenarios faces a significant challenge, e.g. problematic maneuvers in corner cases. Despite recent video generation works are proposed to tackcle the mentioned problem, i.e. models built on top of Diffusion Transformers (DiT), works are still missing which are targeted on exploring the potential for multi-view videos generation scenarios. Noticeably, we propose the first DiT-based framework specifically designed for generating temporally and multi-view consistent videos which precisely match the given bird's-eye view layouts control. Specifically, the proposed framework leverages a parameter-free spatial view-inflated attention mechanism to guarantee the cross-view consistency, where joint cross-attention modules and ControlNet-Transformer are integrated to further improve the precision of control. To demonstrate our advantages, we extensively investigate the qualitative comparisons on nuScenes dataset, particularly in some most challenging corner cases. In summary, the effectiveness of our proposed method in producing long, controllable, and highly consistent videos under difficult conditions is proven to be effective.
