Errors when using FlannBasedMatcher #37

Open dapicester opened 8 years ago

dapicester commented 8 years ago

Instantiating a new FlannBasedMatcher:

require 'ropencv'
include OpenCV

matcher = cv::FlannBasedMatcher.new

the following error occurs:

NameError: undefined local variable or method `flann' for OpenCV::Cv::FlannBasedMatcher:Class
from /home/paolo/.rvm/gems/ruby-2.0.0-p598/gems/ropencv-0.0.21/lib/ropencv/ropencv_types.rb:32672:in `new'

So the error is on the following line:

# overloaded method wrapper for cv::FlannBasedMatcher::FlannBasedMatcher(const cv::Ptr<cv::flann::IndexParams> indexParams = makePtr<flann::KDTreeIndexParams>(), const cv::Ptr<cv::flann::SearchParams> searchParams = makePtr<flann::SearchParams>())
@@cv_flann_based_matcher_flann_based_matcher_defaults0 ||= [cv::Ptr<flann::KDTreeIndexParams>(new flann::KDTreeIndexParams), cv::Ptr<flann::SearchParams>(new flann::SearchParams)]

It seems to me that the flann namespace does not exists or it is not correctly wrapped/exported. In fact I cannot find other references neither to flann nor to KDTreeIndexParams in the file.

Can you please check and tell me if I am missing anything?
