Exclusive feature on ScanSap

Post by yankoch »

Hi,

Here are some news about ScanSap, the point cloud software developed by TagLabs.

We just completed a feature that should interest many point clouds users. First of all, have a look at these screenshots and try to guess what it is.

A: Tomography/volume rendering for point clouds ? --or at least a rough analogy...

Some sort of export function that creates new/virtual scan stations equal distance apart through out the point cloud?

@Scott : I know you've been waiting for the tomograph feature for a long time :-) This feature will help us building what you need.

@Steve: you're really close to the answer. Indeed we build virtual scans, boxes of pointclouds to be precise. The icons you see on the screenshots are the center of the boxes.

The feature is a gridded pointcloud extraction that cuts the pointcloud into multi-clipping boxes. For now, these boxes are cubes, but we will do custom parallelepipeds soon.

So, why doing this? We've been working on point clouds for years, and CAD / BIM softwares aren't really good at displaying massive pointclouds. The key is to load the required area only.

Our partner, Sona Architecture, regularly creates models from hundreds of scans and this helps them a lot.

This feature allows splitting your data into e57 cubes. You define a global bounding box with an origin, a direction, and a grid size, then you add all your original e57 files. As a result, you get new e57 files renamed with an identifier, and a csv file that contains all boxes positions.

Sona did a Revit plugin that allows activating the required boxes. This package could already be proposed as a standalone solution. We did a realistic test on a 470 scans survey splitted into 5 meter cubes.

In future, we'll try to do a direct fls to rcs cubes. This feature is the first part of a work on advanced clipping.

Small demo of the result:

Hi,

Here's an article about our scan to grid feature I just published on Linkedin. I hope your automatic translator will keep it understandable.
