Using XGrids innovative devices for spatial data acquisition for Mega

This section introduces how to use the laser scanning equipment from XGrids Innovation XGrids to capture environments, then reconstruct using LCC Studio and export the data required for EasyAR Mega.

전체 프로세스

Using XGrids Innovation XGrids devices for Mega typically involves the following steps:

• Acquisition path planning. Plan the acquisition route in advance based on the area to be captured, especially when capturing large-scale scenes.
• On-site data acquisition. Use supported laser devices to capture environmental data on-site.
• Process raw data using LCC Studio. Import on-site captured data into LCC Studio on a computer to reconstruct the scene's 3D data.
• Upload data to Mega cloud to generate localization maps. Select the files required by Mega from the LCC Studio results and upload them to the server.
• AR content placement and remote testing. View the reconstructed scene in 3D engines like Unity, design AR content, perform remote debugging, and package the application.
• On-site testing and experience.

Mega에서 지원하는 XGrids 장비 유형

Currently, Mega supports the following XGrids devices:

• PortalCam P1 (PortalCam)
• Lingguang series

참고

EasyAR Mega currently does not support direct upload of raw data scanned by XGrids Innovation devices. Instead, it needs to be processed in LCC Studio first and exported to the required format. To check the devices supported by the current version of LCC Studio, refer to the corresponding user manual.

경로 계획 및 현장 데이터 수집

How to use XGrids Innovation devices to capture high-quality data can be found in the guides and tutorials provided on the XGrids Innovation Developer website.

We recommend reading the LCC Acquisition Tutorial to master high-quality scanning techniques.

• Read the official XGrids LCC Acquisition Guide to understand important considerations during acquisition.

• PortalCam P1 Acquisition Guide to learn how to operate and use PortalCam P1 for acquisition.

LCC Studio를 사용하여 스캔 데이터 처리

For how to use LCC Studio to process on-site scanned data, refer to the official LCC Studio tutorial for detailed operational guides.

• Download LCC Studio, user manuals, and release notes from the LCC Studio official website.

• Watch the LCC Studio tutorial series to learn about scene generation and editing.

LCC Studio 결과에서 Mega에 필요한 파일 찾기

After completing scene generation in LCC Studio, you can find the files needed for Mega development on your computer. The specific method is as follows:

• Under My Scenes in LCC Studio, click the ... in the upper right corner of your environment.

• Select Open File Location to open the relevant files on disk. In this directory, you can find the files required by Mega.

  • In the ply-result\point_cloud\iteration_100 directory, the 3D-GS file in point_cloud.ply format is stored.
  • In the render directory, the 3D-GS file in lcc format (*.lcc) is stored.
  • In the render\assets directory, the poses.json file recording the acquisition trajectory is stored.

참고

You can also use the File -> Export function in LCC Studio and select the 3D-GS file in ply format to export to a custom directory for Mega.

다음 단계

You need to upload the above LCC Studio reconstruction result files to the EasyAR server. For specific methods, see Uploading XGrids Data to Mega Server.
