This module is designed to advance the student’s knowledge of 3D rendering and re-construction through use of the Axon Investigate 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.
