Video Analysis
The examination and utilization of video for reconstruction
Our forensic experts use a methodology called matchmoving for analyzing objects (vehicles, pedestrians, etc.) visible in video captured by moving and/or zooming cameras.
Matchmoving (also referred to as “camera tracking”) is a photogrammetric technique used to solve for or “match” the movement and optic properties (i.e. Field of View (FOV), focal length, lens distortion, optical center, etc.) of the real-word camera that captured the video, in order to “calibrate” an identical virtual camera. Once a virtual camera is calibrated, vehicles, pedestrians, and other objects depicted in the video can be accurately tracked to determine and analyze the translation, orientation, velocity and acceleration of those objects.
In addition to video analysis, the matchmoving process also allows computer generated, 3D virtual objects to be accurately composited into the video footage with correct position, scale, and orientation, which results in very compelling, photorealistic animations.
