The second module in this series will be offered for live viewing on April 29, 2025, beginning and 10:00 am PT. The duration is expected to be two hours, including Q&A. A recording will be made available for those who cannot attend live within 24 hours.
The first module in this series was offered on November 13th, 2024. If you missed the live session, you can still register to view the recording here.
Future sessions will be announced as they become available.
Module One: The first segment of the series covered the basics of frame timing and the primary vehicle positioning methods, including:
- Reverse projection
- Surface Drawing
- Line of sight
- Passing points
- Pixel tracking
Attendees will learn the fundamentals of each approach, be exposed to the available software packages, and evaluate the suitability of each method for specific scenarios.
By attending, you'll gain valuable insights and practical skills to enhance your speed analysis capabilities.
Module Two: The second installment in the series will focus on utilizing passing points and line of sight methodologies for determining speed from video. There will be step-by-step instruction showing how to complete the process, as well as a review of available software to complete the analyses, both paid and free. Attendees will also be provided with exclusive batch files for FFmpeg and raw materials to complete their own analysis, if they choose to do so.
Future modules will cover additional methods in detail, teaching the attendee how to fully complete the photogrammetric processes.
Will the modules be eligible for ACTAR CEUs?
The first module has been approved for 2 CEUs and we expect future modules to be approved for 2 CEUs, as well. We will submit the CEUs on your behalf (through 5/6/24 for the second module). Both attendees of the live webinar and those who watch the recording will be eligible to receive ACTAR CEUs.
Can I attend future modules without attending the first?
Yes! Each module can be viewed independently of the others.
Will the sessions be recorded?
Yes! Registered participants will receive login information to watch the recorded webinar at a time that's convenient to them.

Series Modules

Given the current ubiquity of cameras, reconstructionists are consistently challenged with calculating a vehicle’s speed from video. To address this, Lightpoint’s upcoming webinar series, hosted by Lou Peck (Professional Engineer and ACTAR-accredited reconstructionist), will explore the primary techniques used to determine speed, and provide a detailed look into the most popular software programs utilized by the community. Please see below for specific topics covered in the available modules.

Module Two - Passing Points and Line of Sight Methodologies

The second module in the series will be presented on April 29th, 2025 from approximately 10:00 am - 12:00 pm PT, including Q&A.

This module will provide an in-depth look at the passing points and line of sight methodologies and the software available for completing these analyses, both paid and free. Attendees will be provided with exclusive FFmpeg batch files that facilitate lossless frame extraction and detailed analysis of metadata. Raw materials (video and point clouds) will also be provided for those who wish to perform the processes themselves.

Attendees will learn how to:

Capture the necessary site measurements using various methods (from laser scanners to Nearmap)
Export lossless frames with various programs, both paid and free
Analyze frame metadata with Amped FIVE and FFmpeg
Determine travel distance via passing points using CloudCompare, Google Earth, and 3D CAD
Determine travel distance via line of sight method using 3D CAD
Calculate speed and acceleration using Excel
