## Overview
-Autoware expects to have multiple sensors attached to the vehicle as input to perception, localization, and planning stack. These sensors must be calibrated correctly, and their positions must be defined using either urdf files (as in [sample_sensor_kit](https://github.com/autowarefoundation/sample_sensor_kit_launch/tree/main/sample_sensor_kit_description)) or as tf launch files.
+Autoware expects to have multiple sensors attached to the vehicle as input to perception,

+and planning stack.
+These sensors must be calibrated correctly,

In order to do that, we will use TIER IV' [CalibrationTools](https://github.com/tier4/CalibrationTools) repository.

+
+In previous section (creating the vehicle and sensor model),

+So, our `sensors_calibration.yaml` file for our tutorial_vehicle should be like this:

+ roll: 0.0
+ pitch: 0.0
+ yaw: 0.0

+
+You need to update this transformation value according to the `sensor_kit_base_link` frame.

+## Intrinsic camera calibration
+
+Unlike other calibration packages in our tutorials,
+this package does not need to create an initialization file.
+So we can start with launching intrinsic calibrator package.
+
+```bash
+cd
+source install/setup.bash
+```
+
+After that, we will launch intrinsic calibrator:
+
+```bash
+ros2 launch intrinsic_camera_calibrator calibrator.launch.xml
+```
+
+Then, initial configuration and camera intrinsic calibration panels will show up.
+We set initial configurations for our calibration.
+
+
+ { width="200"}
+
+ Initial configuration panel
+
+
+
+We set our image source (it can be "ROS topic", "ROS bag" or "Image files")
+from the source options section.
+We will calibrate our camera with "ROS topic" source.
+After selecting an image source from this panel, we need to configure "Board options" as well.
+The calibration board can be "Chess board", "Dot board" or "Apriltag".
+Also, we need to select board parameters,
+to do that, click the "Board parameters" button and set row, column, and cell size.
+
+After the setting of image source and board parameters, we are ready for the calibration process.
+Please click the start button, you will see "Topic configuration" panel.
+Please select the appropriate camera raw topic for the calibration process.
+
+
+ { width="200"}
+
+ Topic configuration panel
+
+
+
+Then you are ready to calibration.
+Please collect data with different X-Y axis, sizes and skews.
+You can see your collected data statistics with the clicking view data collection statistics.
+For more information,
+please refer to [Intrinsic Camera Calibrator](https://github.com/tier4/CalibrationTools/blob/tier4/universe/sensor/docs/how_to_intrinsic_camera.md) page.

+
+ Intrinsic calibrator interface
+
+
+
+After the data collection is completed,
+you can click the "Calibrate" button to perform the calibration process.
+After the calibration is completed,
+you will see data visualization for the calibration result statistics.
+You can observe your calibration results with changing "Image view type "Source unrectified"
+to "Source rectified".
+If your calibration is successful (there should be no distortion in the rectified image),
+you can save your calibration results with "Save" button.
+The output will be named as `_info.yaml`.
+So, you use this file with your camera driver directly.
