How to Use MetaView, the LiDAR Viewer from Seyond (Intermediate Level)

MetaView is a point cloud viewer provided by Seyond specifically for their in-house LiDAR. No installation is required, and after a simple registration, you can download it from the website and start using it right away.
Operation is intuitive and GUI-based, and in addition to visualizing 3D point cloud data, it also supports recording, playback, and analysis functions.

Following on from the previous basics article, this intermediate article will clearly introduce some useful on-site features with examples to help first-time users get started more smoothly.
Please try out MetaView, which combines intuitive operability with multifunctionality.

*For details on each function, please refer to the provided manual.

1. Recording LiDAR acquired point cloud data

This article is a quick manual for those who own Seyond LiDAR, and it assumes that you have downloaded the software and manual from the website and have already set up an environment in which you can use it. If you have not done so, please first refer to the previous article, "How to use MetaView, the viewer for Seyond LiDAR (Basics)," and make the necessary preparations in advance, such as setting up the software and connecting the LiDAR.

How to use Seyond's LiDAR Viewer MetaView (Basics)

1. Point cloud data recording procedure (file creation)

MetaView can record the displayed LiDAR point cloud data and also play back the recorded data. It supports a variety of settings, but here we will introduce the basic usage.

1. Point cloud recording button

Click the Record button on the bottom right function key.

2. Recording time setting

The control menu has the following items: recording mode, save path, save format, recording unit, and file name, but basically everything except the recording unit is available by default.
The default recording unit is "1", which is the number of seconds of recording time, meaning 1 second of recording.
Therefore, we would like you to change the time to your liking, and we usually recommend 15, 30, or 60 seconds.
OTHERS, you can also change the save path etc.

3. Start recording

Recording can be started by clicking the "Start Recording" button at the bottom of the radar control menu.
When recording is complete, a file with a name based on the date and time, such as "20260110143555_MetaView.inno_pc", will be created on your PC's desktop (default) or in a directory of your choice.

*The above is a file created at 14:35:55 on January 10, 2026.

File name: yyyymmddhhmmss_MetaView.inno_pc

2. Playback of recorded point cloud data

Recorded point cloud files can be easily played back by following the steps. First, select the point cloud file you want to play and then run the playback function. During playback, you can check the status of the point cloud using basic operations such as moving the viewpoint and zooming in and out. Pause and resume as needed to efficiently view the desired scene.

The playback procedure is as follows:

1. How to play back recorded data

Click Local Point Cloud Player from the function keys at the bottom right.

Second circular iconClick to open the control window shown below.

Left folder iconSimply click and the system file selector will automatically pop up. Select the point cloud file you want to play and playback will begin.

Default file storage location = Desktop

■TIPS

Default point cloud file name = yyyymmddhhmmss_MetaView.inno_pc
Example: 20260210100407_MetaView.inno_pc

2. How to return to LiDAR point cloud display

Stop playing the recorded data and switch to viewing the LiDAR input.

Click the “Connect LiDAR” button to connect the LiDAR.
The display will switch to the LiDAR point cloud.

3. Grid line display

MetaView also allows you to adjust settings such as grid line visibility and display style. Here we will show you how to control grid line visibility as you wish.

1. Show/hide grid lines

Click the Radial Grid button from the function keys at the bottom right.
Click the second circular icon Radial Grid Icon to open the control window.

You can toggle the grid display on and off using the grid SWITCHES at the bottom.

2. Display settings

MetaView allows you to configure various settings related to grid display. You can change the grid spacing, line thickness, numerical display size, etc. to suit your needs. In this column, we will explain "grid spacing" and "display limit distance" as typical examples.

1. Grid spacing

You can choose the grid line spacing from the following four levels:
10m/25m/50m/100m

2. Setting the grid display distance limit

You can set the maximum distance (limit) at which the grid is displayed. For example, if you set the limit distance to 200m, the grid beyond that distance will not be displayed.

■TIPS

*The grid may be too noticeable if left at its default settings. As shown in the image above, adjusting the grid line width (thickness) and font size to make it more subtle will make the point cloud easier to see.

3. Point cloud confirmation (analysis)

1. Check the point cloud of any part

You can display point cloud information for the selected area by holding down the "z" key and dragging the left mouse button on the screen to specify the range of points you want to check. This is a convenient function for checking the number of points contained in an object and understanding distances.

1. Check detailed point cloud data

Total: Total number of point cloud data in the selected area
Dist: Measurement distance from LiDAR

Num: Serial number of each point group (example = 0 to 3804)
X/Y/Z: Coordinates of each point group (unit: m)
Ref: Reflection value (0 to 255)
Int: Reflection intensity (Intensity 0~255)
Fct: Flag/type code (discrete value)
Chl: Channel (laser/receiving channel number)
Line: Scan line (scanning column/line)
Idx: Internal index
Roi: ROI flag (Yes = 1 / No = 0)

2. Utilizing recorded point cloud data

1. Multifaceted analysis is possible using recorded data

Seyond allows you to effectively utilize recorded data acquired by LiDAR with MetaView. The various functions introduced so far can be used on recorded data as well as real-time data. Checks from various angles, which are difficult to do in real time, can be repeatedly verified and analyzed using the same data, greatly expanding the possibilities for LiDAR system development.

2. Analysis examples using video recordings

The example below shows the result of point cloud analysis performed on the car seen in the center in the previous section, viewed from directly above and then enlarged.

Data taken at an angle allows for more accurate confirmation of the total number of points, distance, etc.
In this way, the recorded data can be used for various analyses, allowing for time-consuming analysis.
