Impact of Transformer Cross Encoder (Ablation Study)
Problem: Without the Transformer Cross Encoder, the CART model's performance significantly degrades in point cloud registration.
Solution: The Transformer Cross Encoder module captures complex relationships between points and integrates information from source and target PCDs.
Impact: Removing this module led to rotation errors increasing by 42% to 336% and translation errors by 119% to 389%, underscoring its critical role in reducing both rotation and translation errors, especially at larger rotation angles.
