title: Mat to vector<Point3f>
body: <p>I have a vector of vector and I want to take values from matrix type MAT and assign these values to it.
  I am using eclipse and I am trying to push back on the vector like that</p>
  
  <pre><code>vector&lt;Point3f&gt; output;
  output.push_back(Point3f(Transformed_world_coordinates.at&lt;Point3f&gt;(0, 0)));
  output.push_back(Point3f(Transformed_world_coordinates.at&lt;Point3f&gt;(1, 0)));
  
  </code></pre>
  
  <p>the problem is when I run , I get really high values in most of the vector, sth like 7.47385e+027 which is totally not what I am trying to assign 
  I checked the output of the matrix right before I use the previous code and the numbers are in the way I want(ex:0.02345458)</p>
