realsense-align

pre-commit License: BSD 3-Clause-Clear PyPI - Version

Porting librealsense C++ align code to Python C++ extension. Align depth and color image from numpy array without librealsense SDK and rs:frame infrastructure.

Prerequisites

  • uv
  • OpenMP

Build

uv build

Install

Install from PyPI

python -m pip install realsense-align

How to use

See tests/test_align.py for detail.

Run the test code by pytest tests.

Example

mmwave-capture-std RGB+Depth Video Player

Set up the virtual environment using uv

uv sync
source .venv/bin/activate

Then, run the code to show the RGB+Depth video

python examples/play_depth_video.py path/to/capture_00001

[IPorting

  • struct Intrinsic
  • Depth to color align
  • Color to depth align

Trade-off

  1. Don't care distortion: See librealsense#1430 for more information.

  2. Don't care extrinsic: Assume the following:

Rotation: [[1, 0, 0], [0, 1, 0], [0, 0, 1]]
Translation: [0, 0, 0]

See src/proc/align.cpp for original implementation, and rs2_extrinsicsStruct Reference for rs2_extrinsics structure.
