LM-O

홈페이지 · 논문 1편

The LM-O (Linemod-Occluded) dataset, introduced by Brachmann et al. in their work on 6D object pose estimation, provides additional ground-truth annotations for all modeled objects in one of the test sets from the Linemod (LM) dataset. This extension introduces challenging test cases with various levels of occlusion ¹²³. Here are the key details about the LM-O dataset: - Objective: The primary goal of the LM-O dataset is to evaluate the performance of 6D object pose estimation methods under occlusion conditions. - Source: The dataset builds upon the Linemod dataset, which was originally proposed by Hinterstoisser et al. in their work on model-based training, detection, and pose estimation of texture-less 3D objects in heavily cluttered scenes ¹. - Annotations: LM-O provides additional ground-truth annotations for all other instances of the modeled objects in one of the Linemod test sets. These annotations include information related to occlusion, making it a valuable resource for assessing pose estimation algorithms in challenging scenarios ¹. - Test Cases: The LM-O dataset includes test images showing one annotated object instance with significant clutter but only mild occlusion. By incorporating occluded instances, it simulates real-world scenarios where objects may be partially hidden or obscured ¹. - License: The dataset is available under the CC BY-SA 4.0 license, allowing researchers to use and build upon it for their own investigations ¹. Researchers and practitioners can leverage the LM-O dataset to develop and evaluate robust 6D object pose estimation methods that can handle occluded objects effectively. It serves as a valuable benchmark for advancing the field of computer vision and robotics. (1) Datasets - BOP: Benchmark for 6D Object Pose Estimation. https://bop.felk.cvut.cz/datasets/.
