The iNPUT-ACE Metrologist Certification gives students the foundational knowledge needed to get accurate measurements of distance and time from video evidence.

The certification track is $995 and includes both modules of Metrology: Calculating Speed From Video and Reverse Projection: Camera Match Overlay. Payment for this class you will automatically enroll you in both modules. Contact us with any questions or to change your schedule.

If you simply want to purchase a voucher for both classes and choose a date at a later time, please do so here. If you already have a voucher and want to schedule for this specific class, add this event to your cart and you select “redeem voucher” as payment method.


Event Details

This module is designed to advance the student’s knowledge of 3D rendering and re-construction through use of the iNPUT-ACE Camera Match Overlay Tool. Students will learn to use the Overlay Tool to overlay video evidence on top of point cloud data, allowing for accurate measurements and calculations within a documented margin of error. Additionally, students will gain the ability to measure object locations through Reverse Projection and 3D laser scan geometry.

The content for this class is delivered in two parts: First, students must watch a 2-hour, pre-recorded video that focuses on theory. Second, students will attend a 3-hour live, hands-on session with the instructor.
