how can i do the following conversion
vector<vector> in c++ to numpy array in python
Thanks in advance for helping
How is this an OpenCV problem? General C++/Python questions should be directed to an appropriate forum.
because I need to operate with cv::Point2D and the chances of ppl struggling with the same problem could be higher here. Let me know if u want me to delete the post!
that conversion is done automatically by the OpenCV Python bindings.
which specific OpenCV function are you having trouble with?
actually my problem is a bit different.
I am trying to compute the largest rectangle inside a polygon. The polygon is represented by a contour. I want to use the LIR python package to solve this (as a c++ implementation doing the same has bugs while I have validated the python package works). This is the package
I need to pass a numpy nd array of points represnting contours… For example like this [[[1,1], [2,3], [4,5], [6,7]]]
Im am rying to call it through PyArrayObject, PyArrayObject and PyObject_CallFunctionObjArgs mechanishmes where I have coded the generation of numpay array from the contour data structure by defining it as std::vector<std::vector<std::vector > >
The PyArrayObject seems to work but when I pass it to the lir function using PyObject_CallFunctionObjArgs it returns a null object (but no seg faults).
So wanted to ask here if there is a direct option within opencv to generate the PyArrayObject for contour default data structures
std::vector<std::vector<cv::Point > >
