The Metrologist course Includes two, 4-hour courses (8 hours total). Operator and Examiner Certifications are required.
These modules are designed to enhance participants’ understanding of 3D rendering, reconstruction, and accurate timing calculation from videos.

By learning to utilize the AXON Investigate Camera Match Overlay Tool and the AXON Investigate Frame Rate (VFR) Lightboard, participants will develop the necessary skills to overlay video evidence onto point cloud data, ensuring precise measurements and calculations within a documented margin of error.

Moreover, participants will gain proficiency in utilizing recorded video while considering challenges like variable refresh rates, compression, rolling shutter, and more, which can complicate these calculations. Additionally, participants will acquire the ability to measure object locations through Reverse Projection and 3D laser scan geometry.

Furthermore, they will grasp the fundamental components of video files and how different codecs interpret metadata, which can introduce inaccuracies in older speed calculation methods, thanks to the introduction of HEX.

Course Prerequisites

Operator and Examiner Certification should be completed before beginning Metrologist training.
