Hotel & Travel Information

Photographs and video recordings of vehicle crashes and accident sites are more prevalent than ever, with dash mounted cameras, surveillance footage, and personal cell phones now ubiquitous. The information contained in these pictures and video provide critical information to understanding how crashes occurred, and in analyzing physical evidence. This course teaches the theory and techniques for getting the most out of digital media, including correctly processing raw video and photographs, correcting for lens distortion, and using photogrammetric techniques to convert the information in digital media to usable scaled three-dimensional data. Hands-on training using actual case studies and a variety of software titles such as 3D Max, Photomelder and PTLens, will introduce the students to the latest techniques.

Learning Objectives
By attending this seminar, attendees will be able to:

  • Remove lens distortion from photographs and video
  • Utilize the latest techniques in photogrammetry software
  • Accurately locate roadway evidence using photogrammetry
  • Determine crush measurements from photogrammetry
  • Create photogrammetry-based point clouds
  • Analyze video footage for object positioning and timing
  • Effectively present your findings in court

Who Should Attend
This course is geared toward individuals interested in video and photographic analysis, including engineers, accident reconstructionists and investigators, and law enforcement. Individuals working in the field of autonomous vehicles and remote sensing will also find the concepts presented relevant since the photogrammetry principles taught in the course are the same used in the cameras and sensors installed on vehicles.
