The iNPUT-ACE Metrologist Certification gives students the foundational knowledge needed to get accurate measurements of distance and time from video evidence. Instructors will use the iNPUT-ACE VFR Lightboard to diagnose common errors that can come from counting frames. In the second course, students will go in-depth with using the Camera Match Overlay Tool for overlaying the video evidence on top of point cloud data for accurate measurements and calculations within a documented margin of error.

The certification track includes one 4-hour and one 5-hour course including Calculating Speed From Video and Reverse Projection: Camera Match Overlay.

Event Details

Students will learn how to calculate accurate timing from video using the iNPUT-ACE VFR Lightboard instead of frame counting. This method will help students understand how to utilize recorded video while acknowledging the challenges that can complicate these calculations such as compression, rolling shutter and more. The introduction to HEX will help students understand the basic building blocks of video files and how different codecs read the metadata that can create inaccuracies in older methods of calculating speed.

Learning Objectives

  • Detailed Timing Metadata
  • Intro to HEX

  • VFR Lightboard Use

Recommended Prerequisite

  • iA Operator (or equivalent experience)
  • iA Examiner (or equivalent experience)

Who Should Attend?
