feat: added deviation_estimator unit_tool #149

Closed SakodaShintaro closed 10 months ago

SakodaShintaro commented 10 months ago

Description

I created a unit tool of deviation_estimator that loads rosbag and performs calibration.

Context

The current deviation_estimator is implemented as a ros2 node, so it takes the same amount of time as the rosbag used for calibration.

Also, since it is a ros2 node, there is a problem that slight variations occur depending on the execution, making it impossible to reproduce same results.

By implementing it as a unit tool that directly loads rosbag, it runs in seconds and deterministically.

I think migration (removal of ros2 node version and rewriting of README) will be done in another PR in the future.

Tests performed

I ran deviation_estimator on several rosbags and confirmed that results close to conventional ones were obtained.

Example

as a ros2 node

# Estimated by deviation_estimator
/**:
  ros__parameters:
    angular_velocity_offset_x: -0.00030
    angular_velocity_offset_y: -0.00238

    angular_velocity_stddev_xx: 0.00596
    angular_velocity_stddev_yy: 0.00596
    angular_velocity_stddev_zz: 0.00596
