General / Can I use Lidar data with gcp?

Hello Everyone



Can I use Lidar data with gcp for more accuracy?

point cloud with georeferencing

General / Interval Cross section
« on: December 22, 2022, 01:49:44 PM »
Hello

I usually use profile with polyline

but civil engineering use a cross-sectional view. and I draw polyline one by one

So I want to use cross section at interval.

Can i use that?

General / Re: Aerial Lidar data merge Terrestrial laser scan data

Hello TJ Jeong,

In Metashape 2.0 you can place markers on the point clouds directly (without images) and use them for laser scans alignment.

Hello Alexey

I converted laser scan and place marker las and e57 too. but they didnt merge correctly(they placed different location)

i attached images.

so what can i do this problem?

Hi TJ Jeong,

I havn't done this myself (because we don't have aerial Lidar), but I think that both should be in the same coordinate system. Doesn't you have GCPs in the same system for both?


Best regards

Kiesel

Hello Kiesel

When i place marker(GCP) las and e57 too, and try to merge

but didnt merge same point. like attachment photo

Hi TJ Jeong,

you might have a look here for Metashape 2.0 beta:

Hello Kiesel

I try this. but TLS doesnt have location. so when i input las and e57, their location isnt match.

so i cannot merge these files

Can you explain specific process procedure?

General / cross profile
« on: November 28, 2022, 11:16:25 AM »
Hello Agisoft Team

I use civil engineering, so i often use measure profile

but I want to use cross profile only one click.

Can I use this profile measurement?

General / Aerial Lidar data merge Terrestrial laser scan data
« on: November 28, 2022, 11:02:10 AM »
Hello Agisoft Team

I want to merge Aerial Lidar data(.las) with Terrestrial Laser scan data(ex. pts, ptx, e57...etc)

Las data has coordinate. but TLS data does not have coordinate(no georeference)

So how can i do this?

General / Metashape Point Cloud size bigger
« on: November 17, 2022, 08:53:08 AM »
Hello Agisoft Team

I use Polyline vectorization in Metashape

i want to draw polyline in point cloud (like lidar...) but if i do zoom, point size is small, so draw polyline is hard.

So i want to view point cloud size bigger(no density)

how can i do in metashape?
