Summary

Laser scanning, characterized by the great minuteness of data and the high precision as well as a relatively short surveying time, has already been applied in the majority of industry branches. However, various researches are still conducted in order to expand the rangę of its usefulness, even in such areas of life as medicine, archaeology, safety and forensic science. Taking into consideration its possibilities, special attention deserves the idea of implementing the technology of the terrestrial laser scanning to the work in the police, thereby enabling the increase of the studies’ accuracy, the enrichment of the techniques applied so far, and also the acceleration of activities executed on the scene.

Thanks to the cooperation with the institutions, the survey of three various events was performed, i.e. the deadly accident with a motorcyclist, the two-vehicle road collision and the murder scene. Field works consisted of carrying out local vision, the placement of signals, and also defining the approximate location of the scanner positions. In order to do the proper survey for the given event, suitable parameters of scanning ought to be marked. Point clouds, collected from laser scanning, were subject to the preliminary Processing in order to form the spatial model of the event place. In the next stage, the data was processed in specialist software used for generating projections and sections, and also creating superficial models. On the basis of the conducted research, the advantages of the use of the terrestrial laser scanning technology in the process of documenting the places of events were proved.
