Recording data

Note

Internet connection is not required on this stage, as data is stored locally.

  1. Check the device and recording requirements.

  2. Go to the CityLens tab and select one of the recording modes:

    • Free roam mode: driving without a specified route. In this mode, you can take photos or record videos to collect data.
    • Task mode: completing a task from the Task planner. If the administrator assigns you a task to cover an area, you can select it in the mobile application and use the built-in navigator to move along the required route.
    Selecting modes on the CityLens tab

    Follow the instructions on working in the free roam mode or the task mode.

  1. Choose the recoding method: taking photos or recoding a video. The chosen recording method launches.

    Before starting the recording, you can see current recording parameters. You can configure them in settings.

    Recording configuration info
    • Frames: number of frames (images tied to geographic coordinates) captured by the application and not yet uploaded for processing. When you record a video, frames are captured automatically depending on the configured frequency.
    • Tracks: number of recorded and not yet uploaded tracks (time intervals and data collected during it).
    • Length: duration of the current track in minutes. You can configure the maximum track length in settings.
    • Frame rate: frequency of frame capturing. You can configure it to depend on speed, distance, or time intervals.
    • JPEG: image resolution. You can select the level of image compression in settings.
    • Thermal state: indicator of the processor heating state.
    • Free space: available amount of device memory.
    • Accuracy: accuracy of determining the device geolocation.
  3. Tap the capture button to start recording.

    Important

    Follow the recommended speed limit to ensure high quality of captured frames.

  4. Open the map by tapping the round map icon in the lower-left corner.

    You can also configure the map look to make it more convenient for your work: select a theme, enable tracking the traveled route, and more.

  5. To enable navigation mode, tap Route icon. Using the navigator is not required, however, it guides you along the most optimal route to complete the task.

    Task navigation mode

    In navigation mode, the following route data is displayed at the bottom of the screen:

    • expected route duration
    • expected time of arrival to the finish point
    • route length
    • number of tracks recorded by the current moment

    To zoom out and see the full route, tap Map icon.

    To stop navigation, tap Cross icon. You can resume navigation at any moment from any plane on the map: the application will recalculate the route based on new conditions.

  6. To finish or suspend working on the task, return to the recording mode and tap the recording button again.

Uploading in progress

Note

Uploading the tracks might take a while depending on the amount of data. You can continue taking photos or working with other application tabs.

The uploaded data becomes available in the administrator tools.

Once the data is uploaded, go to the Statistics tab to view the updates on the total traveled distance and the number of captured and uploaded frames. The data is relevant for the current day only.

Detected frames count in the Statistics tab

Once the frames are processed, the statistics are updated to display the number of detected objects.
