摘要:

自治系统需要理解其周围环境的语义和几何,以便理解和安全地执行对象级任务规范。本文提出了一种表达而紧凑的模型,用于联合对象姿态和形状优化,以及一种相关的优化算法,用于从多视图RGB-D相机观察中推断对象级地图。该模型具有表现力,因为它捕捉了环境中对象的身份、位置、方向和形状。它是紧凑的,因为它依赖于隐式对象形状的低维潜在表示,允许板载存储大型多类别对象映射。不同于其他作品,依赖于一个单一的对象表示格式,我们的方法有一个双层次的对象模型,捕捉粗级别的规模以及精细的形状细节。我们的方法进行了评估的大规模现实世界的ScanNet数据集,并与国家的最先进的方法进行比较。

英文摘要:

Autonomous systems need to understand the semantics and geometry of their surroundings in order to comprehend and safely execute object-level task specifications. This paper proposes an expressive yet compact model for joint object pose and shape optimization, and an associated optimization algorithm to infer an object-level map from multi-view RGB-D camera observations. The model is expressive because it captures the identities, positions, orientations, and shapes of objects in the environment. It is compact because it relies on a low-dimensional latent representation of implicit object shape, allowing onboard storage of large multi-category object maps. Different from other works that rely on a single object representation format, our approach has a bi-level object model that captures both the coarse level scale as well as the fine level shape details. Our approach is evaluated on the large-scale real-world ScanNet dataset and compared against state-of-the-art methods.
