Forensic 3D Laser Scanning of Footwear Impression Evidence Thesis Proposal

Forensic 3D Laser Scanning of Footwear Impression Evidence - Thesis Proposal Example However, getting a 3D physical cast of an impression on a crime scene can in the process destroy the evidence. The use of 3D imaging device is proving to be beneficial to crime scene investigators (CSI) as an additional toolkit since it can obtain details of such impression. Footwear impression recovery in crime scene is considered to have a critical role in the investigations to narrow down the number of suspects or refute or corroborate information (Gamage et al., 2013). Three dimension foot ware impressions casting is seen to be a long standing standard where, it results to the generation of three dimensional footprints. This is progressively being replaced by a three dimensional scanning that is a less invasive method. In the study proposed, an alternative method that entails a 3D laser scanning of footwear impression evidence with the use of a FARO "Freestyle" 3D Scanner will be present, and it will be based on the multi-view stereo where, an accurate three dimensional model can be generated. The results on the reconstructed three dimensional models will be evaluated and then compared with other results obtained by three dimensional scanning. Also, the drawbacks and the advantages of this method will be explored over other methods that exist. Freestyle hand held scanner was recently released by FARO, and this is considered as a step up in structured light technology because it includes two cameras infrared in nature which are used in creating a stereo pair of images Three dimensional foot ware impression casting is progressively being replaced by a three dimensional scanning that is less invasive method. In the study to be undertaken, an alternative method that entails a 3D laser scanning of footwear impression evidence with the use of FARO "Freestyle" 3D Scanner will be present and it will be based on the multi-view stereo.
