Adapt Depth Anything V3 Small to an 8 GB Jetson Orin Nano Super for incremental multi-view point-cloud reconstruction with overlapping windows.

Research question

How effectively can Depth Anything V3 Small be adapted for incremental, spatially coherent point-cloud reconstruction on an 8 GB edge device?

Architecture

calibrated RGB camera
    → slow, overlapping frame selection
    → 4-frame DA3 window with 2 retained overlap frames
    → relative depth + confidence + intrinsics + camera poses
    → confidence-filtered window point cloud
    → overlap-based Sim(3) alignment
    → bounded global point cloud
    → live viewer and export

Locked defaults

  • Model: depth-anything/DA3-SMALL
  • Runtime: official Python API with PyTorch FP16
  • Primary configuration: 4 frames, 2-frame overlap, 336 px
  • Fallback: 3 frames, 2-frame overlap, 280 px
  • Memory gate: peak used memory below 7.0 GB
  • Confidence filter: discard the lowest 40% per frame
  • Map bounds: 30 accepted windows and 1,000,000 points
  • Live target: one accepted viewer update every five seconds
  • Scale: arbitrary internal units until an independent 1.0 m reference is applied

Evaluation

  • Evaluation Plan — evaluation questions, locked test configuration, and acceptance summary
  • Test Protocols — step-by-step resource, geometry, alignment, performance, and stability tests
  • Results Templates — tables, required figures, and reporting guidance

Milestones

  • Freeze the Jetson software stack and camera mode
  • Calibrate the camera below 0.5 px mean reprojection error
  • Pass the DA3 Small resource-feasibility gate
  • Validate DA3 output shapes and coordinate conventions
  • Export a confidence-filtered point cloud from one window
  • Align two recorded windows with Sim(3)
  • Accumulate a bounded recorded room sweep
  • Integrate live capture and continual viewer updates
  • Apply independent scale normalization and measure the doorway
  • Complete the five-minute performance test
  • Complete the 15-minute stability run
