Ray's SketchUp modeling with 3D Scanner

Hi Ray,

Thanks for your sharing :+1:โ€ฆ Are you still using real works for your post process and/or are you using other tools for cleaning before importing into SU?

Thanks again
David

Hi djoseph,

Since we use the Trimble Scanner, we have no choice but to use realworks.
However, we also use handheld scanners, so we use Cloud Compare to remove pointcloud noise.

To sum up, realwoks registers data from multiple scanners, exports them in las format, and removes noise from Cloud Compare to import into SketchUp.

I hope your question is answered.
Ray

Hi Ray,

Thanks for your answer โ€ฆ i will have a look at Cloud compare :wink:

The project featured in this post was featured on the SketchUp Blog as the first study case in the APAC region. :kissing_smiling_eyes:

Wonderful / beautifull / just wow.
Dare I ask how much time this effort tookโ€ฆ?

It took about 3 months. Because the drawings used for remodeling need to be created in the sketchup, it took a long time to model accurately.

Very nice model !

All this is pretty wonderful looking, and you seem to be doing this quickly. Does the process entail completely modeling in SketchUp from scratch? Canโ€™t say I understand how the cloud model relates to SketchUp, other than a visual reference. Impressive body of work and scope!

Thanks for your comment.

Since this project is to reverse engineer a baseball stadium without drawings, everything was modeled from the point cloud acquired with 3D Scanner and Drone.

Point cloud is only a set of points that have coordinates consisting of x,y,z and color information expressed in r,g,b, but it becomes raw data that can be easily modeled by using Undet for SketchUp Extension.

I hope this is the answer to your question.

hello,

I recently tried trimble scan essentials to build up a model from point cloud. Have you tried it ? how would you compare it to undet ?

hello,

Yes, of course I tested it.

Trimble Scan Essentials (TSE) is a big step forward over Trimble Scan Explorer Extension for SketchUp.

However, for our project, we will choose Undet for SketchUp for the following reasons.

-Real-time Point Cloud Density change function (Undet)
-Feature extraction function (Undet)
-Point Cloud storage function in Section Box area (Undet)
-Use of TSEโ€™s rwp file format (convenient only for Trimble Scanner, increased memory occupancy)

I hope this is the answer to your question.
