Background:

Accurate 6D pose estimation is crucial for robot grasping, especially for weakly textured objects.
Existing methods like DOPE struggle with real-time performance and recognition efficiency for such objects.

Purpose of the Study:

To develop an improved 6D pose estimation algorithm (DOPE++) for weakly textured objects using RGB-D images.
To enhance the real-time capabilities and recognition accuracy of existing deep learning models for robot grasping.

Main Methods:

Introduced depthwise separable convolution to lighten the DOPE network structure for faster processing.
Incorporated an attention mechanism to boost network accuracy.
Developed a random mask local processing method and a multiscale fusion module to handle occlusions and scale variations.

Main Results:

DOPE++ significantly improves the real-time performance of 6D pose estimation.
Enhanced recognition of parts across different scales without compromising accuracy.
A hybrid dataset, including a virtual dataset, was constructed to address background representation limitations.

Conclusions:

The proposed DOPE++ algorithm offers a robust solution for 6D pose estimation of weakly textured objects.
The enhancements enable more efficient and accurate robot grasping in complex scenarios.
Data augmentation using virtual datasets improves model generalization.
