Shield Tunnel Convergence Diameter Detection Based on Self-Driven Mobile Laser Scanning
The convergence diameter of shield tunnels is detected by ellipse fitting or local curve fitting to cross-section points. However, the tunnel section, which is extruded by an external force, has an irregular elliptical shape, and the waist of the tunnel is often blocked by accessories, resulting in...
