Image Quality Assurance

Camera Settings

  • Take a sample recording while driving the Amiga to the field (at the speed you hope to drive the Amiga through the field).
  • View the recording in the file manager app to observe any issues with blur, exposure, occlusion, shadows, or camera position / perspective.
    • Use the dropdown in the top left to toggle which Oak camera's recording is shown.
  • Before beginning recording for the day, use the settings icon in the Camera App to show each camera's output on the display.
    • Use the Auto Exposure and Auto Focus buttons to recalibrate each camera if there appears to be an issue.
  • Once you have verified that the image quality looks correct, recording can begin once the GPS RTK connection has been made.

GPS Quality Assurance

  • Connect GPS Base Station to WiFi and ensure that the attena is connected to the base station.
  • It is recommended that the attena is placed outside with a clear view of the sky.
  • Connect the Amiga to WiFi as well and go to the settings GPS NTRIP tab.
  • NOTE: The Amiga and Base Station DO NOT need to be on the same WiFi network, but they do need to be connected to the internet.
  • Ensure that a green notification appears in the top right corner of the screen indicating that the GPS is connected to the base station.

Data Collection

  • Please go through the Pre-Data Collection steps before proceding.
  • We assume your field experiment is split into columns and rows.
  • Drive your Amiga to the start of the first column and press the Record button in the Camera Recorder App.
  • The Amiga will begin recording the camera data and GPS data.
  • At the end of the first column, press the Stop button in the Camera Recorder App.
  • If you have different experiments in the same column, you may stop recording at any point and start a new recording.
  • However, it is difficult to track recordings if you stop and start recording multiple times in the same column.
