示例1: read_from_yaml
void read_from_yaml(FileNode node, cv::Vec2f& v)
{
CvMat* c_m;
c_m = (CvMat*)node.readObj();
ntk_throw_exception_if(!c_m, std::string("Could not read field ") + node.name() + " from yml file.");
cv::Mat1f m (c_m);
ntk_assert(m.cols == 2, "Bad vector.");
std::copy(m.ptr<float>(), m.ptr<float>()+2, &v[0]);
}示例2: read
void Object::read(const FileNode& node) {
if (node.isNamed())
name_ = node.name();
else
cout << "Warning : no name for this object." << endl;
node["number_views"] >> number_views_;
node["features_type"] >> features_type_;
views_.resize(number_views_);
for ( int i = 0; i < number_views_; ++i ) {
ostringstream view_stream;
view_stream << "view_" << i;
node[view_stream.str()] >> views_[i];
}
