Background technique

When an injured person is injured or dies due to an accident, the forensic doctor needs to examine and measure facial or body surface scars or scars and pigment changes of the injured and/or deceased, especially facial scars or scars and pigment changes The measurement of area is critical to the correct application of the standard clauses. It needs to be accurate to the millimeter level, and it is clearly required that photos should be kept, and a lifetime responsibility system for appraisal should be implemented. For those with a small area and a relatively flat area, at present, computer software is mostly used to measure the area after film tracing, and two-dimensional images of the measurement area can also be obtained by drawing, photography, etc., and the area measured by the two-dimensional image is used to calculate the plane. area. However, for those with a wide range of uneven facial parts that may reach the critical value specified in the standard clauses, the aforementioned method obviously does not meet the requirements due to the single measurement data obtained and the simple calculation method, and scars and/or pigment changes will cause Changes occur due to the extension of time, and it is difficult to judge whether the measured data of the original identification is accurate. Although it is possible to obtain 3D images through 3D CT imaging, 3D MRI imaging, 3D laser scanning, stereo photography, Moiré method, acoustic 3D imaging, etc., it is more accurate to obtain 3D parameter information of human body structure, but it has not yet been seen. To related devices specifically for the measurement of maxillofacial scars or pigment changes. To this end, we propose a device for measuring maxillofacial scars or pigment changes.
