Application Introduction of 3D Forensic Injury Measurement and Reconstruction System in Criminal Investigation Technology and Forensic Identification — A Digital Solution for Human Injury Identification
The 3D Forensic Injury Measurement and Reconstruction System (Non-contact 3D Scanning Measuring Instrument) is a specialized digital identification equipment for human injury in the fields of criminal investigation technology and forensic identification. Based on binocular structured light 3D reconstruction technology, it integrates scanning and collection, data processing and electronic file management functions. It solves the pain points of traditional manual measurement, such as high subjectivity, invasiveness and difficulty in data traceability, and provides non-contact, high-precision and quantifiable technical support for forensic identification of personal injury cases in criminal investigation, ensuring that the conclusions of injury identification are scientific, fair and traceable.
The core functions of the system are accurately adapted to the needs of criminal investigation and forensic identification: non-contact optical scanning can avoid secondary injury to sensitive injuries such as burns and open wounds, eliminate cross-infection, and is suitable for emergency injury identification scenarios at criminal investigation sites; high-precision measurement of 0.045-0.1mm, combined with authoritative calibration parts, ensures the accuracy of data such as injury area and length, and resolves disputes over critical value identification; digital modeling and comparison functions can clearly present injury morphology, compare wound healing or scar changes, and provide quantitative basis for injury mechanism analysis and injury degree assessment; full-process electronic archiving retains scanning models, measurement data and operation logs, forming a complete electronic identification file, which helps in the review of criminal case identification and the fixation of evidence.
Combined with criminal investigation practical cases, its application value is prominent: Case 1, in an intentional injury case, the victim had irregular open wounds on the body surface, and traditional measurement had large errors. With the non-contact scanning of this system, a 3D model was quickly generated, the wound area and maximum diameter were automatically calculated, and the injury degree was accurately defined. The data was verified by calibration, providing solid support for the forensic identification conclusion and effectively resolving disputes between the two parties. Case 2, in a domestic violence injury case, the system scanned the victim's injury site multiple times, quantitatively displayed wound healing and scar changes through 3D superposition comparison, and combined with electronic files, provided traceable digital evidence for criminal investigation filing, dynamic assessment of forensic injuries and case trial.
In summary, the system is suitable for scenarios such as injury identification, injury degree assessment and injury mechanism analysis of personal injury cases in criminal investigation. It can significantly improve the efficiency and accuracy of identification, realize the digitization of the identification process and traceability of evidence, standardize the forensic identification process, and provide scientific and fair technical support for the detection of criminal cases and judicial trial. It is an indispensable professional human injury analysis equipment in the fields of criminal investigation technology and forensic identification.
