摘要:

6D位姿估计在增强现实、虚拟现实、机器人操作和视觉导航等领域都有着重要的应用。然而,由于现实世界中的各种对象,该问题具有挑战性。它们具有不同的3D形状,并且它们在捕获图像中的外观受到传感器噪声,不断变化的照明条件和对象之间的遮挡的影响。不同的姿态估计方法具有不同的优点和缺点,这取决于特征表示和场景内容。同时,用于数据驱动方法以估计6D姿态的现有3D数据集具有有限的视角和低分辨率。为了解决这些问题,我们组织了关于6D姿态估计的形状检索挑战基准,并创建了一个物理上精确的模拟器,该模拟器能够生成具有相应地面真实6D姿态的照片级逼真的颜色和深度图像对。从捕获的彩色和深度图像中,我们使用该模拟器生成一个3D数据集,该数据集具有400个照片级逼真的合成彩色和深度图像对,具有各种视角用于训练,另外100个捕获和合成图像用于测试。五个研究小组在这个轨道上注册,其中两个提交了他们的结果。数据驱动的方法是目前的趋势,在6D对象的姿态估计和我们的评估结果表明,充分利用的颜色和几何特征的方法是更强大的反射和无纹理的对象和遮挡的6D姿态估计。该基准和比较评估结果有可能进一步丰富和推动6D目标位姿估计及其应用的研究。

英文摘要:

6D pose estimation is crucial for augmented reality, virtual reality, robotic manipulation and visual navigation. However, the problem is challenging due to the variety of objects in the real world. They have varying 3D shape and their appearances in captured images are affected by sensor noise, changing lighting conditions and occlusions between objects. Different pose estimation methods have different strengths and weaknesses, depending on feature representations and scene contents. At the same time, existing 3D datasets that are used for data-driven methods to estimate 6D poses have limited view angles and low resolution. To address these issues, we organize the Shape Retrieval Challenge benchmark on 6D pose estimation and create a physically accurate simulator that is able to generate photo-realistic color-and-depth image pairs with corresponding ground truth 6D poses. From captured color and depth images, we use this simulator to generate a 3D dataset which has 400 photo-realistic synthesized color-and-depth image pairs with various view angles for training, and another 100 captured and synthetic images for testing. Five research groups register in this track and two of them submitted their results. Data-driven methods are the current trend in 6D object pose estimation and our evaluation results show that approaches which fully exploit the color and geometric features are more robust for 6D pose estimation of reflective and texture-less objects and occlusion. This benchmark and comparative evaluation results have the potential to further enrich and boost the research of 6D object pose estimation and its applications.
