“…The term photogrammetry encompasses any technique used to obtain reliable measurements from photographs. Photogrammetric techniques include single-photograph and multiplephotograph techniques and consist of both graphical and analytical methods (Gillen 1986, Tumbas 1994). The last three decades have witnessed increasing application of photogrammetric techniques within motor vehicle accident reconstruction.…”

This paper presents an image analysis of a laboratory-based rollover crash test using camera-matching photogrammetry. The procedures pertaining to setup, analysis and data process used in this method are outlined. Vehicle roll angle and rate calculated using the method are presented and compared to the measured values obtained using a vehicle mounted angular rate sensor. Areas for improvement, accuracy determination, and vehicle kinematics analysis are discussed. This paper concludes that the photogrammetric method presented is a useful tool to extract vehicle roll angle data from test video. However, development of a robust post-processing tool for general application to crash safety analysis requires further exploration.

“…CRPP is a technique utilized by accident reconstructionists to locate information from photographs through the use of computer software. Though the mathematical theory behind the process of photogrammetry is beyond the scope of this paper, the foundation for photogrammetry and its use in accident reconstruction has previously been established in a variety of papers [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

“…In one sense, the receipt of surveillance video can simply be considered a set of "photographs" for the reconstructionist to utilize during their analysis. As such, photogrammetric techniques can be utilized to take measurements of the objects observed in the surveillance video [1,2,3]. The aforementioned relative permanence of the surveillance camera location, however, eliminates one workflow that needs to be accounted for as part of a photogrammetric analysis of post-incident photographs -the physical location of the camera itself.…”

The frequency of video-capturing collision events from surveillance systems are increasing in reconstruction analyses. The video that has been provided to the investigator may not always include a clear perspective of the relevant area of interest. For example, surveillance video of an incident may have captured a pre-or post-incident perspective that, while failing to capture the precise moment when the pedestrian was struck by a vehicle, still contains valuable information that can be used to assist in reconstructing the incident. When surveillance video is received, a quick and efficient technique to place the subject object or objects into a three-dimensional environment with a known rate of error would add value to the investigation. In addition, once the objects have been placed into the three-dimensional environment, the investigator would then be able to observe the physical evidence and environment from any perspective, including viewing and measuring what cannot be seen in the video perspective. In this research, the proposed photogrammetric technique of visually placing objects within three-dimensional laser scans will be evaluated. This research aims to quantify the rate of error of taking measurements of these objects to known fixed reference points both in and out of view of the camera, and provide an efficient technique that can be employed by reconstructionists using only one software package. As a result of this research, the authors have developed an expedient, less time-intensive photogrammetric technique for the placement of threedimensionally scanned objects and environments. This technique can take less than half of the time of a conventional photogrammetric solution.
