Libcbdetect
---
- Unofficial implemention of [libcbdetect](http://www.cvlibs.net/software/libcbdetect/) in C++.  
- Deltille detector.  

Libdetect is a fully automatic sub-pixel checkerboard / chessboard / deltille pattern detection. The algorithm autmatically extracts corners to sub-pixel accuracy and combines them to (rectangular) checkerboards / chessboard-like / deltille patterns.  
  
My calibration tool: [Libcalib](https://github.com/ftdlyc/libcalib)
  
#### Require
- C++ 14  
- Opencv >= 3.0  
  
#### Example
> using namespace cbdetect;  
> cv::Mat img = cv::imread("image.bmp", cv::IMREAD_COLOR);  
> Params params;  
> find_corners(img, corners, params);  
> plot_corners(img, corners);  
> boards_from_corners(corners, boards);  
> plot_boards(img, corners, boards);
