AI Technical Summary

Technical Problem

Traditional underground pipeline route planning algorithms are computationally intensive in complex 3D spaces, generate uneven paths, lack generalization ability, and struggle to meet multiple design objectives simultaneously, as well as adapt to environmental changes.

Method used

A virtual scene-based visual navigation method is adopted. Offline supervised learning is performed through policy network and value network to generate an initial policy model with obstacle avoidance and target approach capabilities. The model is then iteratively optimized under the DDPG learning system to generate a smooth and continuous 3D pipeline path.

Benefits of technology

The generated pipeline paths are smoother and more natural in three-dimensional space, have strong generalization ability, can adapt to local terrain changes, meet actual engineering needs, reduce construction difficulty and pipe breakage rate, and achieve multi-objective optimization.
