+## Introduction
+
+Accurate 6D pose estimation of complex objects in 3D environments is essential for effective robotic manipulation. Yet, existing benchmarks fall short in evaluating 6D pose estimation methods under realistic industrial conditions, as most datasets focus on household objects in domestic settings, while the few available industrial datasets are limited to artificial setups with objects placed on tables. To bridge this gap, we introduce CHIP, the first dataset designed for 6D pose estimation of chairs manipulated by a robotic arm in a real-world industrial environment. CHIP includes seven distinct chairs captured using three different RGBD sensing technologies and presents unique challenges, such as distractor objects with fine-grained differences and severe occlusions caused by the robotic arm and human operators. CHIP comprises 77,811 RGBD images annotated with ground-truth 6D poses automatically derived from the robot's kinematics, averaging 11,115 annotations per chair. We benchmark CHIP using three zero-shot 6D pose estimation methods, assessing performance across different sensor types, localization priors, and occlusion levels. Results show substantial room for improvement, highlighting the unique challenges posed by the dataset.

+### Data Fields
+```
+- scene_id: Unique identifier for each scene in the dataset (BOP format).
+- image_id: Unique identifier for each image within a scene and camera type (BOP format).
+- camera_type: Type of camera used to capture the image (e.g., 'zed', 'rs_l515', 'rs_d435').
+- image: RGB image captured by the specified camera.
+- depth: Depth image corresponding to the RGB image, captured by the specified camera.
+- width: Width of the image in pixels.
+- height: Height of the image in pixels.
+- split: Dataset split to which the image belongs (e.g., 'test_no_occlusions', 'test_moderate_occlusions').
+- source_image_id: Original image identifier from the CHIP dataset.
+- labels: JSON string containing object annotations, including 6D poses and visibility information.
+- camera_params: JSON string containing intrinsic and extrinsic camera parameters for the specified camera.
+```
+
+### Uses
+
+The CHIP dataset can be used for a wide range of research tasks, including:
+
+- Benchmarking 6D pose estimation in realistic industrial environments
+- Evaluating robustness to challenging conditions, such as occlusions, clutter, and visually similar distractor objects
+- Studying cross-sensor generalization across LiDAR-based, passive-stereo, and active-stereo RGB-D sensors
+- 6D pose tracking during robotic manipulation, including motion sequences with dynamic occlusions
