Low-Shot Wall Defect Detection for Autonomous Decoration Robots Using Deep Reinforcement Learning

Abstract EN

Wall defect detection is an important function for autonomous decoration robots.

Object detection methods based on deep neural networks require a large number of images with the handcrafted bounding box for training.

Nonetheless, building large datasets manually is impractical, which is time-consuming and labor-intensive.

In this work, we solve this issue to propose the low-shot wall defect detection algorithm using deep reinforcement learning (DRL) for autonomous decoration robots.

Our algorithm first utilizes the attention proposal network (APN) to generate attention regions and applies AlexNet to extract the features of attention patches to further reduce computation.

Finally, we train our method with deep reinforcement learning to learn the optimal detection policy.

The experiments are implemented on a low-shot dataset in which images are collected from real decoration environments, and the experimental results show the proposed method can achieve fast convergence and learn the optimal detection policy for wall defect images.
