volt-industrial-23cls

Volt industrial 23-class semantic segmentation

This repository contains the deployment artifacts for a Volt-S model fine-tuned on a custom industrial RGB-D point-cloud dataset.

The matching Docker/FastAPI service is the volt branch of mingqian0850/industrial_3d_sem_seg_server. It implements the same isaac-capture.v1 request and response contract as the project's DiTR and PTv3 deployments.

Files

• config.py: frozen training/evaluation configuration.
• volt-industrial-23cls.pth: inference-only checkpoint containing the EMA state_dict.
• sha256sums.txt and md5sums.txt: artifact integrity checks.

The inference checkpoint was extracted from model_best.pth at epoch 98. Its recorded best validation mIoU is 0.9250934182924747. Optimizer, scheduler, scaler, and the non-EMA training weights were intentionally omitted from this deployment artifact.

Input and preprocessing

The model consumes XYZ coordinates plus six input features:

• RGB scaled from [0, 255] to [0, 1]
• surface normals (nx, ny, nz)

Deployment uses the frozen test pipeline from config.py: 2 cm grid voxelization, inverse mapping to the original valid depth points, XY centering, color normalization, and Volt tokenization with a 5-voxel patch size. The service uses a fixed voxel representative seed for repeatable requests.

Intended use

This model is intended for the industrial scene domain represented by its training data. Performance under new sensors, layouts, materials, noise profiles, or class taxonomies should be validated before production use.
