AR ColorMapping

This project is an easy-to-apply AR Coloring Library for Unity.
This project can be applied to AR Engines of MaxstAR, EasyAR, Vuforia, ARFoundation(ARkit, ARcore).
To use it for business projects, you need to purchase a separate license for the AR Engine.

Release

Future Release

• We will add a method for creating coloring 3D content in the near future.

Trouble Shooting

• If an error such as "Undefined symbols for architecture arm64" occurs.
  　　example:
  

 Undefined symbols for architecture arm64:
 "cv::getPerspectiveTransform(cv::Point_<float> const*, cv::Point_<float> const*)", referenced from:
 _ImageProc in libAirarColorMap.a(AirarColorMap.o)
 (maybe you meant: cv::getPerspectiveTransform(cv::Point_<float> const*, cv::Point_<float> const*, int))
 ld: symbol(s) not found for architecture arm64
 clang: error: linker command failed with exit code 1 (use -v to see invocation) 

　　solutions:

　　Be sure to use version 3.4.11 of the opencv framework.

Known issues

• The coloring is not very accurate when used with the MaxstAR engine.
