Introduction to Photogrammetry and Mobile LiDAR Scanning

March 2, 2021 @ 2:00 pm - 4:00 pm


Please REGISTER in advance here.

Workshop will be conducted in Zoom in PST time. Invites are sent out the day before the workshop.


3D models can be formed in a number of ways. Two common surveying methods that result in 3D models are photogrammetry and light detection and ranging or lidar for short.

A form of photogrammetry has been around since the beginnings of photography in the mid-19th century. The term usually refers to the method by which 2D images are compared and combined using optics, projective geometry, and computing to produce a 3D model. This method of image overlap to create a dimensional model is applied in many object-oriented disciplines such as archeology, topographic mapping, architecture, engineering, manufacturing, quality control, police investigation, cultural heritage, and geology.

Lidar is a method for measuring distances (ranging) by illuminating the target with laser light and measuring the reflection with a sensor. Differences in laser return times and wavelengths can then be used to make digital 3D representations of the target. While long used in the earth sciences, lidar is becoming increasingly available to all as these sensors are being added to cellular mobile devices, increasing its academic and commercial potential.

In this workshop, participants will learn about the hardware and software required for these methods. We will also cover the workflow that is involved in producing photogrammetric and lidar 3D models. All levels welcome.

If you have any further questions regarding the workshop, please contact the instructor, Dr. Francesca Albrezzi at falbrezzi@ucla.edu
