pub fn read_trajectory(
    traj: &mut dyn ToOutputArray, 
    files_format: &str, 
    start: i32, 
    end: i32, 
    tag: &str
) -> Result<()>

takes vector<Affine3> with T = float/dobule and loads poses from sequence of files

Parameters

• traj: Output array containing a lists of poses. It can be - std::vectorcv::Affine3f, std::vectorcv::Affine3d - cv::Mat
• files_format: Format specifier string for constructing filenames. The only placeholder in the string should support int.
• start: The initial counter for files_format. It must be greater than or equal to 0.
• end: The final counter for files_format.
• tag: Name of the matrix in the file.

C++ default parameters

• files_format: "pose%05d.xml"
• start: 0
• end: INT_MAX
• tag: "pose"
