mapry LA03 Android App Manual

mapry LA03

This is a user manual that describes how to use the hardware device "LA03" that works in conjunction with the Android app mapry.


Although there is no limit to the continuous operation time per measurement for the mapry LA03, we recommend up to 30 minutes. *One measurement refers to the time from the start to the end of one scan.


When storing the mobile battery, do not leave it in an environment below 0 degrees.

If the mobile battery is cold, it may not be able to provide enough power to your device and it may not work.

Do not leave the mobile battery in an environment below 0 degrees.

If the mobile battery is cold, it may not be able to provide enough power to your device and it may not work.

The included battery may change depending on the shipping time. Even if the terminal shape is the same, it may not be able to output the power required to drive the LA series, so please do not use the terminals listed below.


Anker included battery - can be used with either Type A connector.
The included cheero battery - cannot be used with the Type C terminal marked PD18wOUT.
The included veektomx battery cannot be used with the Type C terminal marked -OUT only.
Included battery made by CIO - can be used with either Type-C terminal.

When using spare batteries or other accessories other than those provided by our company, please be aware of the following points.

Type C terminal - The terminal must be capable of outputting PD20V1.5A or more.
Type A terminal must be capable of outputting -5V 2.4A or more.
You will also need a mobile battery that can output approximately 60W simultaneously across all terminals.

2.2.5. Start Scan

When starting measurement, make sure the LA03 and smartphone are in a straight line.

Also, when displaying the route measured by the IMU, adjust the position of your smartphone so that the red arrow on the map points in the direction of travel.

 

  • If measurement starts normally

    "Scanning" will be displayed in the center of the screen. Once "Scanning" is displayed, point cloud acquisition will begin.

 

  • If a problem occurs during measurement

    An error dialog will appear stating "A problem has occurred" and the scan will automatically stop.
    Please note that this may occur when scanning at close range (up to 2m) or in places with extremely few distinctive features.

  • If a problem occurs when starting a measurement

    The following dialog appears.

    • If the temperature of the LA03 body exceeds 70°C, you can start scanning by pressing "Yes".
      However, please note that the device may suddenly stop working if the temperature exceeds 80°C.

    • When the capacity of the USB memory exceeds 95%
      Please organize the contents of the USB memory.

     

2.2.6. Autosave

 

Once scanning begins, scan data (point cloud, video, markers, coordinates, and self-position) will be automatically saved once per minute.
When ① and ② are displayed, auto-save is complete.

Also, the application may freeze during the scan.
If the screen freezes, please end the app task, restart the app, and then display the LiDAR screen.
Once you hear the message "Scanning," you can continue scanning.

 

2.2.7. Automatic marker placement

Only one point (the starting point) is automatically obtained as a marker.
You can then convert the point cloud to public coordinates by manually placing markers.
In addition, the location information used to acquire markers is the value from a smartphone or GNSS receiver.
If a GNSS receiver is connected, the position information from the GNSS receiver will be used preferentially.

 

2.2.8. Marker placement

There are two types of markers that can be used during scanning:

  • Green Marker
    • Obtain the location and image of LA03.
      If the GNSS receiver is connected, it will obtain coordinates at the same time.
  • Photo marker
    • Tap the orange icon and then tap the "+" button to launch the camera.
      After launching the camera, take a photo and tap the ✓ button.
      The acquired markers will be automatically linked to the GIS as points with photos.

 

2.2.9. Stop Scanning

Tap the stop scan button in the center of the screen.
The following dialog will appear, so tap the "OK" button.
