English(EN) XM4D: 4D Reconstruction through Certifiable Geometric Optimization

新框架通过先进的优化和级联模型解决4D重建问题 · 已追踪2个来源

两篇新研究论文XM4D和SM4RT介绍了从RGB视频进行4D重建的新框架。XM4D通过将相机运动和非刚性变形估计分离为结构化QCQP问题,利用可验证的全局最优几何优化。SM4RT采用级联前馈模型,在估计运动之前依次重建3D几何,通过在每个相机帧内表达像素运动来减少歧义。这两种方法都旨在提高动态场景重建的准确性和效率。 AI

影响 这些新框架在动态场景重建方面提供了进步,有可能改善机器人、自动驾驶和增强现实等领域的应用。

    XM4D:通过可验证的几何优化实现四维重建

    arXiv:2611.07902v1 Announce Type: new Abstract: Accurate 4D reconstruction remains challenging: jointly estimating camera motion, scene geometry, and non-rigid deformation entails highly nonconvex optimization, making global optimality difficult to guarantee. We present XM4D, a f…

    SM4RT: 用于四维重建的级联前馈模型

    arXiv:2611.08436v1 Announce Type: new Abstract: We introduce SM4RT, a multi-task cascade feed-forward model for dynamic scene reconstruction from RGB videos. While existing feed-forward approaches typically address geometry reconstruction and motion estimation separately--and oft…
