Virtual CRASH 6 includes a full set of tools for video and image analysis. Chapter 26 of the User's Guide covers the range of analyses you can perform with them. Camera matching, though, starts with reference points that are common to your survey data and to features visible on the image plane. What can you do when no such points exist, for example when all you have is the video and the vehicle year, make and model? Below we discuss the Projected Length Analysis approach, and how object tracking paired with our web-based PLA estimator can produce a speed estimate quickly.
