aprilgrid 0.3.0
Aprilgrid
Pure python version of aprilgrid
Inspired by Apriltag and Kalibr. There's lot of existing python binding of apriltag. But as everyone knows, python binding causes a lot of issues. So I rewrite a pure python version of apriltag and it's also able to detect aprilgrid.
Install from PyPI
pip install aprilgrid
Usage
Some examples of usage can be seen in the example/main.py file.
from aprilgrid import Detector
detector = Detector("t36h11")
detector.detect(img)
Kalibr uses 2 bit black border while apriltag3 uses 1 bit black border for each tag. The default of aprilgrid follows Kalibr. Please use t36h11b1 if you're using tags with 1 bit black border.
Development
git clone https://github.com/powei-lin/aprilgrid.git
cd aprilgrid
pip install -e .
TODO
Add output for opencv calibrate camera.
Provide pregenerated pdf and easy way to customize.
Support all tag families.
Accelerate and multi-threading.
Robustness.
