Robust Object 6D Pose Estimation Under High Dynamic Ambient Light

This paper addresses the challenges in object 6D pose estimation caused by illumination changes, proposing an improved Gen6D method for robust operation under high dynamic ambient light conditions. Our approach first utilizes a convolutional neural network (CNN) for 2D object detection. A channel attention mechanism is then integrated to promote inter-channel information exchange and reduce noise, leading to more robust feature representations. We employ a fast image-matching algorithm for initial pose estimation, followed by a 3D CNN to refine the pose.

In the broader publication record, this work sits in Computer-Aided Design and Applications, 23(4):411-427 and connects to practical problems in 3D sensing, computational geometry, and industrial machine vision.
