This study aims to meet requirement of rapid detection of the TBM (tunnel boring machine) tool's wear state. To this end, the local region-growing method based on normalized cross-correlation was proposed to detect the block slag on belt conveyor and the least-square method for ellipse fitting was employed to measure the size. Firstly, the monocular color image was decomposed into two gray-scale images...
The exact value iteration for POMDP planning is so complex that we use approximation to solve the problems in practice. In recent years, point-based algorithm has become a research hotspot. PBVI algorithm selects successors that improve the worst case density as rapidly as possible. The smaller the gaps between all belief points, the faster the value function converges to the optimal solutions. PBVI...
