The invention discloses a multi-frame superposition
point cloud super-resolution
system for three-dimensional reconstruction, particularly relates to the field of
structured light three-dimensional scanning, and is used for solving the problem that a thick shell and false details are formed due to the fact that abnormal points and geometric conflicts are mixed and fused during repeated scanning and superposition. The method comprises the following steps: collecting multi-frame
structured light point clouds of the same target to generate a multi-frame
point cloud set, synchronously generating a point-level
confidence set, registering the multi-frame
point cloud set to obtain a
pose transformation result, generating a unified coordinate point cloud set, and generating a point-level registration residual set; generating a complementary sampling
label on the unified coordinate point cloud set according to a fringe phase
reproduction degree parameter and a line-of-
sight interlayer separation parameter, outputting a complementary
point set, an abnormal
point set and a to-be-corrected
point set, and executing attachment merging and limited fusion according to the complementary sampling
label to obtain a super-resolution point cloud result. And the point-level
confidence set and the complementary sampling
label are updated through re-input consistency
verification, and a super-resolution point cloud result subjected to
verification constraint is output.
