Exploring Photogrammetry and LiDAR Scanning: A Comprehensive Guide for New Users

Photogrammetry and LiDAR (Light Detection and Ranging) scanning are powerful technologies that have revolutionized the way we capture and create 3D models of the real world. These techniques find applications in fields ranging from architecture and construction to archaeology and gaming. In this educative blog post, we will explore different ways to create photogrammetry or LiDAR scans using technologies from Navvis, Leica, Matterport, and others. We'll also touch upon the process of optimizing and preparing your 3D models for use in applications like Twinzo, which consumes mesh models in .fbx or .obj format, each under 100 MB in size.

1. Understanding Photogrammetry and LiDAR Scanning

Before we delve into the specifics of different technologies, it's essential to understand the fundamentals of photogrammetry and LiDAR scanning.

  • Photogrammetry: This technique involves capturing 3D data from 2D images taken from various angles. The software processes these images to create a 3D model. Popular tools for photogrammetry include Autodesk ReCap, Agisoft Metashape, and RealityCapture.
  • LiDAR Scanning: LiDAR technology uses laser beams to measure distances and create a detailed 3D point cloud of the environment. LiDAR scanners like those from Leica Geosystems are widely used for mapping and surveying.

2. Choosing the Right Technology

When deciding which technology to use for your project, consider factors like the level of detail required, budget, and the type of environment you're scanning. Here are some options to explore:

  • Navvis: Navvis offers high-end indoor mapping and visualization solutions. Their M6 trolley system combines LiDAR and image data for precise indoor mapping.
  • Leica Geosystems: Leica's LiDAR scanners are known for their accuracy and reliability. Products like the Leica BLK360 are user-friendly and suitable for various applications.
  • Matterport: Matterport specializes in 3D scanning for real estate and property management. Their Pro2 camera simplifies the scanning process and is popular in the real estate industry.

3. Scanning Process

Each technology has its own scanning process. Generally, for photogrammetry, you'll capture a series of images, while LiDAR scanning involves setting up the scanner and collecting data. Follow the manufacturer's guidelines for your chosen technology to ensure the best results.

4. Optimizing 3D Models

Once you have your scans, it's crucial to optimize your 3D models, especially if you plan to use them with platforms like Twinzo, which have file size limitations. Manufacturers often provide software for cleaning and simplifying models. For example:

  • Leica Cyclone: Leica's software suite includes tools for cleaning and decimating point clouds to reduce file size.
  • Matterport Workshop: Matterport offers a web-based platform for processing and optimizing 3D scans.

5. Consulting and Model Processing Services

If you're not confident in optimizing your models or need assistance, consider reaching out to professional consulting and model processing services like Overhead. These experts can help you streamline your 3D models for your specific application.
