Introduction to Lidar
This module is currently in development
Lidar or LiDAR, which stands for Light Detection and Ranging, is a remote sensing method that uses laser pulses to measure distances and create high-resolution, three-dimensional representations of the scanned environment. It is an essential technology in the field of 3D scanning, offering precise and detailed data that is invaluable for various applications in games, visual effects, architecture, engineering, and more. In this introductory module on Lidar, we will cover the fundamental principles of how Lidar works, the different types of Lidar systems, and their specific applications. You’ll learn about the hardware and software tools used in Lidar scanning, as well as best practices for capturing and processing Lidar data to produce accurate and usable 3D models. By the end of this module, you will have a comprehensive understanding of Lidar technology and its applications, preparing you for more advanced topics and practical exercises in the 3D Scanning Masterclass.

Lidar Scanning with the Navvis MLX and VLX3
Scanning with the Navvis VLX and MLX systems offers a cutting-edge solution for capturing large-scale, detailed spatial data efficiently and accurately. These mobile mapping systems integrate LiDAR sensors, high-resolution cameras, and advanced inertial measurement units (IMUs) to produce high-quality 3D point clouds and panoramic imagery. The Navvis VLX, designed for indoor and outdoor environments, provides wearable scanning capabilities, allowing operators to navigate complex spaces like construction sites, factories, or campuses with ease. Similarly, the Navvis MLX system has similar functionality in a more budget friendly and compact system. Both systems leverage real-time localization technology, reducing post-processing time and ensuring precise alignment of scanned data.
Lidar Scanning with the Leica Geosystems BLK360
The Leica Geosystems BLK360 is revolutionizing the way professionals capture and process 3D spatial data through its advanced Lidar scanning technology. The BLK360 occupies a unique price-point without sacrificing data quality. Techniques for optimizing the use of the BLK360 include strategically positioning the scanner to minimize blind spots, ensuring sufficient overlap between scans for seamless stitching, and employing proper scanning resolution settings to balance detail and resolution.
