论文摘要
6D姿势估计是指3D旋转和3D翻译的对象识别和估计。估计6D姿势的关键技术是通过提取足够的功能在任何环境中找到姿势来估算姿势。以前的方法在改进过程中使用了深度信息,或者是为每个数据空间提取功能的异质体系结构设计的。但是,这些方法受到限制,因为它们无法提取足够的功能。因此,本文提出了一个可以从RGB-D中有效提取强大功能的点注意模块。在我们的模块中,注意图是通过几何注意路径(GAP)和通道注意路径(CAP)形成的。在GAP中,它旨在关注几何信息中的重要信息,而CAP旨在注意渠道信息中的重要信息。我们表明,注意模块有效地创建特征表示,而不会显着提高计算复杂性。实验结果表明,所提出的方法在基准,YCB视频和lineMod中优于现有方法。此外,将注意模块应用于分类任务,并确认与现有模型相比,性能显着提高。
6D pose estimation refers to object recognition and estimation of 3D rotation and 3D translation. The key technology for estimating 6D pose is to estimate pose by extracting enough features to find pose in any environment. Previous methods utilized depth information in the refinement process or were designed as a heterogeneous architecture for each data space to extract feature. However, these methods are limited in that they cannot extract sufficient feature. Therefore, this paper proposes a Point Attention Module that can efficiently extract powerful feature from RGB-D. In our Module, attention map is formed through a Geometric Attention Path(GAP) and Channel Attention Path(CAP). In GAP, it is designed to pay attention to important information in geometric information, and CAP is designed to pay attention to important information in Channel information. We show that the attention module efficiently creates feature representations without significantly increasing computational complexity. Experimental results show that the proposed method outperforms the existing methods in benchmarks, YCB Video and LineMod. In addition, the attention module was applied to the classification task, and it was confirmed that the performance significantly improved compared to the existing model.
