non authorised data type #296

Closed MalcolmMielle closed 5 months ago

MalcolmMielle commented 6 years ago

Hej,

Against the latest version of opencv3, processor.h uses non authorised data type for the Mat, line180

  mutable cv::Mat_<uint32_t> wavefront_;
  mutable cv::Mat_<uint8_t> region_types_;
  // scratch buffer for dense point cloud

I have this error on compile

/usr/local/include/opencv2/core/mat.hpp:2150:50: error: no type named ‘channel_type’ in ‘class cv::DataType<unsigned int>’
     typedef typename DataType<_Tp>::channel_type channel_type;

See here. I'm not exactly sure which type I should replace them by

MalcolmMielle commented 6 years ago

I replaced the three offending lines by 


  mutable cv::Mat_<int> labels_;
  mutable cv::Mat_<int> wavefront_;
  mutable cv::Mat_<char> region_types_;
  // scratch buffer for dense point cloud

If it is indeed the good type fix, let me know and I'll push the changes in a merge request

PR welcome

Jammy is opencv 4.5 - so I presume we've fixed these issues at this point
