Abstract
How to process the point cloud data is a research hotspot, among which point cloud registration directly affects synthesis results. The iterative closest point (ICP) algorithm is a common method. However, it requires initial distribution of the registration point cloud and usually falls into optimal solution trap. To address the problem, an optimised ICP algorithm based on a simulated annealing strategy is proposed, which divides the registration process into filtering, coarse registration and precise registration. In filtering process, denoising and down sampling are performed to reduce the data size and improve the subsequent iteration rate; then the point cloud with a closer initial distribution is obtained by coarse registration. Finally, in the precise registration, we introduce the simulated annealing strategy, avoiding the local optimum trap. Experiments show that our method has a higher accuracy rate and contributes to the generation of more accurate and complete models in 3D data reconstruction.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
