虛擬實境應用於司法科學證據研究之初探

Preliminary Study on the Application of Virtual Reality in Forensic Science Evidence

"犯罪現場勘查，礙於傳統搜證工具的限制，目前仍以2D紀錄跡證與犯罪現場，與真實的3D證物或犯罪現場相較，可能丟失關鍵的證據資訊，如何彌補此一問題，是鑑識科學亟待解決的問題。掃描3D的犯罪現場，架構虛擬實境的立體現場，解決傳統2D影像難以呈現不同視角的複雜犯罪空間的真實情況，讓觀察者感受3D的空間真實感。本研究旨在介紹3D掃描、建模等技術整合虛擬實境（VR, Virtual Reality）運用於犯罪現場調查領域。透過說明傳統犯罪空間二維（2D, two dimensions）紀錄的問題，強調三維（3D, three dimensions）掃描技術的運用，可增強證物3D的比對效果；與傳統2D的犯罪現場空間呈現比較，毋需憑藉想像，快速建立的3D模型。另可搭配虛擬實境眼鏡（VR Glasses），即使不方便親臨犯罪現場，亦能觀察不同視角場景之犯罪現場空間的各種跡證。未來可參考搭配使用VR技術，將刑案現場重建從平面的文件或相片，轉為可隨使用者之需求放大、縮小或移動，且更符合實際狀況之虛擬實境，期能協助刑事偵查，進而提升案件偵辦效率。"

"Due to the limitations of traditional evidence search tools, crime scene investigations are still using 2D (two-dimensional) record evidence for crime scenes. Compared with real or virtual 3D (three-dimensional) evidence for crime scenes, critical 2D evidence information may be lost. How to remedy this problem is an urgent need to solve in forensics. Scanning 3D crime scenes, constructing 3D scenes of VR (virtual reality), and solving the difficulty of traditional 2D images to present the real situation of complex crime spaces with different perspectives allow observers to experience the realism of 3D spaces.This research aims to introduce 3D scanning, modeling and other technologies to integrate VR in the field of crime scene investigation. By explaining the problems of traditional 2D recording of crime spaces, and emphasizing the use of 3D scanning technology, the effect of 3D comparison of evidence can be enhanced; compared with traditional spatial presentation of 2D crime scenes. It is no need to rely on imagination to build a 3D model quickly. It can also be equipped with virtual reality glasses, even if it is not convenient to visit the crime scenes in person, investigators can observe various evidence of the crime scenes in different perspectives. In the future, they can refer to the use of VR technology to reconstruct the scene of a criminal case from a flat file or photos for a virtual reality that can be zoomed in, zoomed out or moved according to the user’s needs. It is more in line with the actual situations for criminal investigations in order to further improve the efficiency of case solutions."
