The methodology of the vehicle damage identification was presented in this article. Presented method used reverse engineering methodology for compare the shape of new vehicle, including CAD models of vehicle, and change of vehicle shape after damage. The method is based on three-dimensional scanning technology and photogrammetry. Identification of the defect is divided into two areas: the accurate reproduction of the vehicle surface damage and measure only changes of the base point’s position. In a first method, scanning large areas of vehicle requires connection of the consecutive scanning images of the surface to an object stuck in a random reference points. They form a grid of completing successive scanning images with very high accuracy of the surface point’s position. Measuring the angle and length between reference points, scanned surface is measured and digitized by software. However, do not always have to make as accurate measurements. In the second method there is measured only position of the vehicle base points. They may be dispersed very rare so if a damage is very small position of base points does not change. Sometimes it is reasonable to use the first and the second method together. For this purpose, the photogrammetric system is used in the first stage of the scanning surface. The vehicle specific places that are so-called base points are equipped with appropriate measuring adapters. Taking pictures of the object from these points programmatically determine the distance between reference points. This paper presents a method of surface scanning and processing on digital image scans of the vehicle for the calculation of standard deviations between the surface and the reference points. Presented adapters are used for measurement of base point’s position. Examples of calculations results of base point’s location in multi-wheeled AMV vehicle are described and illustrated in the paper.
