Description:
 
Video evidence of an event or accident can often lead to more questions than answers. Challenges may arise when an event is captured from a single vantage point, at a distance, or only partially. Photogrammetry is the science of extracting reliable measurements from photographs and videos by using known dimensions. With the adoption of laser scanning to digitally document accurate three-dimensional representations of real-world sites and objects, photogrammetry has become an even more powerful tool.

In this webinar, members of Exponent’s Biomechanics, Vehicle Engineering, and Visual Communication practices will discuss the key principles behind camera-matching and present three case examples where these techniques were applied not only to create effective visual demonstratives but also as powerful analytical tools.

KEY TAKEAWAYS

1. Evidence preservation is critically important. If an event is captured by a video recording device, care must be taken to properly preserve the original recorded data as completely and as soon after the event as possible.
2. Photogrammetry can be difficult for a jury to understand. Understanding how to present this scientific analysis in a clear and concise manner is critical.
3. Using technical knowledge of physical principles and applying engineering analysis to evaluate recorded events allows for probing of event details not otherwise possible and may even allow for analysis of portions of an event not captured on camera.
4. Understanding the tolerance of these methods can prove critical for assessing what a recording may or may not actually show.
