 For comparison we also provide the `basalt_mapper_sim_naive` executable that has the same parameters. It runs a global bundle-adjustment on keyframe data and inserts pre-integrated IMU measurements between keyframes. This executable is included for comparison only.

-By default the system starts with `continue_fast` enabled. This option visualizes the latest processed frame until the end of the sequence. Alternatively, the `continue_btn` visualizes every frame without skipping. If both options are disabled the system shows the frame that is selected with the `show_frame` slider and the user can move forward and backward with `next_step` and `prev_step` buttons. The `follow` button changes between the static camera and the camera attached to the current frame.

It is located in the `state_groundtruth_estimate0` folder. Bag files have raw Mocap measurements that are not time aligned and should not be used for evaluations.**
