Mesh Reconstruction Algorithm Based on Modulation Intensity

A region-growing algorithm based on modulation intensity is proposed to reconstruct triangular mesh from point cloud.The algorithm first quantizes the values of modulation intensity, and constructs an initial seed triangle in the region of high modulation.Then the active edge with highest modulation is chosen to grow, the best point is selected by weighted minimal length criterion.Finally, the algorithm refines the boundary of the hole according to the geometry of triangle before filling the hole with radial basis function.Experimental results show that the algorithm is effective to reconstruct uniformly triangular mesh and can preserve the detail features of the object.
