how to use

How to Use sizeless

To begin using sizeless, users typically record a short video of the desired area with a smartphone, which is then processed by the platform's AI to generate 3D models and other outputs.

  • 1Record a short video of the target area (e.g., an open trench, a room) using a standard smartphone.
  • 2Upload the recorded video to the sizeless platform.
  • 3sizeless's AI-assisted algorithms process the video to generate 3D models, 2D floor plans, and BIM-ready outputs.
  • 4Receive high-fidelity 3D models and accurate floor plans, typically within 48 hours per 1,000 m² recorded.
  • 5Integrate the generated data directly into GIS and CAD systems for further analysis and documentation.

Similar Tools

sizeless vs Competitors

sizeless differentiates itself in the AEC technology landscape by offering an AI-powered, smartphone-centric workflow for generating precise digital twins, specifically targeting civil engineering applications like trench and house connection documentation.

1
OpenDroneMap↗

It's a complete open-source toolkit for processing aerial drone imagery into point clouds, 3D models, orthophotos, and more.

While OpenDroneMap can generate 3D models and point clouds suitable for civil engineering, it lacks the specialized AI automation for identifying and modeling trenches and house connections that Sizeless offers, requiring more manual interpretation and processing of the raw data.

2
CloudCompare↗

A powerful 3D point cloud and mesh processing software, excellent for cleaning, editing, segmenting, and analyzing point cloud data from various sources.

CloudCompare is a post-processing tool for point clouds, not a reality capture or automated 3D reconstruction solution like Sizeless. Users would need to generate the point clouds elsewhere and then use CloudCompare for detailed analysis and preparation for GIS/CAD, without Sizeless's AI-driven feature extraction.

3
RealityCapture↗

Known for its speed and accuracy in creating high-quality 3D models from images and laser scans, supporting large datasets.

RealityCapture provides robust 3D reconstruction from reality capture data, but it's a general photogrammetry tool. It doesn't offer the specialized AI for automatically identifying and modeling civil engineering features like trenches and house connections that Sizeless provides, requiring more manual effort in feature extraction.

4
Agisoft Metashape↗

A widely used photogrammetry software that generates high-quality 3D models, orthomosaics, and DEMs from images, with robust georeferencing capabilities.

Agisoft Metashape is a powerful and versatile photogrammetry tool for generating 3D models from images. However, it lacks the specific AI-powered automation for identifying and creating '3D twins of open trenches and house connections' directly for GIS and CAD that Sizeless specializes in, requiring more manual work for feature extraction and classification.
