Background
The forensic medicine is one of national judicial appraisers, and is a set of legal medical appraisal which is carried out by utilizing various technologies or means in important time nodes according to legal rules and industrial operation specifications and carrying out on-site medical investigation, medical tracking evidence obtaining, biopsy observation of injury, autopsy, symptom analysis, test comparison, observation and interrogation, remains appraisal, calling and monitoring and special physical examination. Compared with the way that the clinician only focuses on the living medicine, the modern Chinese medicolegal have both the living medicine and the death medicine as research objects. Forensic science is a scientific and technical person who applies basic medicine, clinical medicine and related criminal science and judicial identification technology to carry out investigation and identification on human bodies (living bodies, corpses and spirits) and crime scenes related to law and make identification. Ancient forensic science is called crash study, which is mainly a simple cadaver form test (does not relate to the content of modern western scientific technology, especially pathology). In modern china, forensic medicine has become a complex open system, actively absorbing knowledge from mathematics, physics, chemistry, biology, psychology and computer science and engineering, integrating modern scientific and technical systems into large-scale, and advancing towards a scientific, normalized, institutional and standardized way. Just like the legal system of the country is divided into the judicial authority, the legal authority and the administrative authority, the legal medical identification is gradually moving to the three fields of the judicial identification, the legal identification and the administrative identification. For the forensic, the human body (living body, corpse) is not the purpose, the forensic spirit and the rights of the human mind are the ultimate purposes, and the medical science is the means for realizing the purpose;
the measurement is to describe the observed phenomenon by data according to a certain rule, namely, to make quantitative description on things, the measurement is to quantify the non-quantitative object, the ruler is a tool for measuring length, and the ruler is usually provided with scales for measuring length.
The legal medical expert needs to measure some basic heights, shoulder widths, chest circumferences, waistlines, hip circumferences, arm lengths and the like before corpse examination, the legal medical expert needs to frequently move the human body in the measurement process, huge physical strength is consumed, two persons are needed to cooperate, and the device and the method for automatically measuring the human body size for legal medical expert detection need to be provided for solving the problems.
