Spatial misalignment after rendering the mesh

[mario0718]

Hi,The handlebar space of electric vehicles is misaligned，How to optimize and solve this problem？

At present, after continuously modifying the configuration item parameters, it has been normal, as summarized below:

1. Some potential improvements: more iterations;

• larger model.geometry.xyz_encoding_config.update_steps;
• larger model.geometry.xyz_encoding_config.n_features_per_level;
• larger model.geometry.xyz_encoding_config.log2_hashmap_size; adopting curvature loss. cat instant-nsr-pl/configs/neuralangelo-ortho-wmask.yaml xyz_encoding_config: otype: ProgressiveBandHashGrid n_levels: 10 # 12 modify n_features_per_level: 8 log2_hashmap_size: 30 base_resolution: 16 per_level_scale: 1.3195079107728942 include_xyz: true start_level: 4 start_step: 0 update_steps: 3000
  2. Complex cases require long training In the given config files, the number of training steps is set to 20000 by default. This works well for objects of simple geometries, like the chair scene in the NeRF-Synthetic dataset. However, for more complicated cases where many thin structures occur, more training iterations are needed to get high quality results. This could simply be done by setting trainer.max_steps to a higher value, like 50000 or 100000.

cat instant-nsr-pl/configs/neuralangelo-ortho-wmask.yaml

trainer: max_steps: 20000 log_every_n_steps: 100 num_sanity_val_steps: 0 val_check_interval: 5000 limit_train_batches: 1.0 limit_val_batches: 12 enable_progress_bar: true precision: 32
