As one of the main assumptions for the accident analysis has been detailed information about vehicle deformation. The precise deformation depth allows to quantify deformation energy and related impact speed. The aim of this paper has been the comparison of two selected methods used for the determination of deformation depth. For the purpose of this paper were selected top-view photography as basic and cheap method and 3D scanning as modern and advanced method. Different vehicles and 2 basic types of damagefrontal and side impact-were chosen for the analysis. Also, the different range of vehicle deformation depth were selected. On the basis of obtained results is possible to determine the applicability of these methods, their advantages and limitations.

“…Traditionally, a measuring tape has been used with a variety of instruments, including another measuring tape, plumb bob, string, plywood, plastic sheet or PVC pipe, to obtain vehicle measurements [1]. This time-consuming method required a reconstructionist to take separate elevation measurements, as well as risk transposing errors when recording the data or entering the data into an electronic format.…”

Three-dimensional digitization (3DD) is the technique of recording position data in an electronic format. This process is performed through the use of coordinate measuring machines (CMMs), a broad classification of instruments whose purpose is to record position data. This paper will introduce 3DD and describe the operational theory behind a variety of CMMs. Applications for 3DD in the field of traffic accident reconstruction will be discussed, as well as the advantages and disadvantages of 3DD over traditional methods. The process of measuring a vehicle with CMMs will be presented along with special survey techniques to more effectively use electronic surveying equipment. Lastly, the means of converting recorded data to usable form will be described and a partial list of manufacturers for CMMs and modeling software will be provided.
