IMU Vehicle Calibration
Overview: IMU Vehicle Calibration App is a software tool that makes the process of calibrating an IMU sensor w.r.t Vehicle simple and quick.
1 Calibration List Page
This page contains the list of calibrations. You can launch an existing dataset, delete and even manage your access to these datasets.
2. IMU Vehicle Calibration Launch
You can select an existing IMU Vehicle calibration from the list page, or click on the “New Calibration” button on the top-right of the calibration list page and select the IMU Vehicle in the window that pops.
3.Start Page
The page lists the important instructions and requirements that you need to follow in order to complete the calibration process.
  • Start the app by clicking on the “Get Started” button
  • Input the name you wish to give this calibration. This name will be shown on the calibration-list page. And then click on “Set Details”
4. Fill in the intrinsic parameters of your IMU Sensor
The IMU sensor has some intrinsic parameters which are needed to interpret the measurements reported by the sensor. Accelerometer has a scale factor and an offset value and the gyroscope has an offset value. Fill the values on the screen where asked to set up the IMU sensor. You can use our IMU Intrinsic Calibration app to get the values for your sensor.
5. Upload the data files
Upload the data files to their section based on the vehicle state mentioned on the image.
6. Calibrate
Once you have uploaded all the files, you will get the “Run Calibration” button enabled for you. Click on it. Once the calibration results have been calculated, the results will appear on the right side of the screen.
7. Visualise
You can visualise the data that you uploaded for the calibration process.
Also, you can visualise the orientation of the imu w.r.t vehicle.
8. Export
You can export the results of the calibration using the “Export” button on the top-right of the page. Fill in the name of the output file and click on Export.
9. Calibration Results:
The Calibration results consist of the roll, pitch and yaw angles of the IMU w.r.t the vehicle.
