Photogrammetry and Analysis of Digital Media C1712

Topics: Accident Reconstruction

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 Studio Max, PTLens, Photoshop, and PFTrack will introduce the students to the latest techniques.

Please note, this course is scheduled to end at 2:00 p.m. on Day 3 to allow attendees to make afternoon flights.

This course has been approved by the Accreditation Commission for Traffic Accident Reconstruction (ACTAR) for 21 Continuing Education Units (CEUs). Upon completion of this seminar, accredited reconstructionists should mail a copy of their course certificate and the $5 student CEU fee to ACTAR, PO Box 1493, North Platte, NE 69103.

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.

You must complete all course contact hours and successfully pass the learning assessment to obtain CEUs.
