I was trying to convert the camera info from a yaml file to sensor_msgs/CameraInfo. The yaml file was loaded successfully. And the error occurs when trying to get the distortion coefficient value :
YAML::Node conf = YAML::LoadFile(yaml_file);
std::vector<double> dd;
dd = conf["distortion_coefficients"]["data"].as<std::vector<double> >();
And the error is like: " terminat called after throwing an instance of
'YAML::TypedBadConversion' what(): yaml-cpp: error at line 0, column 0: bad conversion "
My YAML file for distortion_coefficients is like
distortion_coefficients:
rows: 1
cols: 5
data: [0.013750 -0.162804 0.008105 0.002423 0.000000]
Any idea how to solve it?
Your data doesn't have any commas separating the values, so it can't be read as a sequence of numbers.
If you change it to
distortion_coefficients:
rows: 1
cols: 5
data: [0.013750, -0.162804, 0.008105, 0.002423, 0.000000]
then it should work as expected.
