Description

This invention relates to the field of forensics.

The purpose of the invention is to improve the accuracy of the method.

PRI me R. Mr R., 194A of birth left home and did not return. After 5 months, a skeletal “corpse of an unknown person was found in the forest. With the aim of establishing the identity of the deceased, the investigator delivered the bone remains and lifetime photograph of Mr. R.

By photo-matching images of the skull of an unknown person and photograph c. R. the expert concluded that the cranium could be a part of the R. gr. Calibration examination using the specified objects was carried out using the proposed method.

The anatomical-topographic points taken in forensic medicine are marked on the studied skull.

A black iridial test (IT with a diameter of a circle imitating the iris of 12.1 mm) is made on a flexible tape (a strip of Whatman paper).

An IT equal to 12.1 mm is set in the hole of the left orbits so that it protrudes 3 mm beyond the frontal plane of the orbit, and its longitudinal diameter passes along the incision line of the left eye (the line connecting the middle of the dimple lumen). of the sac and orbital tubercle of the orbital process of the zygomatic bone. TCA and native

the skull

matches that

indicates "correct IT installation.

From an in vivo photograph of R. R., on which the contours are well distinguished, and the right eye's envelope, negatives of various densities and their contour images are made on tracing paper with an iris diameter of 4.0 mm.

ten . A skull is installed with the presence of IT equal to 12.1 mm in the left orbit on a tripod in the perspective of the head in the photograph c. R.; On the frosted glass of the FK-1 camera, the contour is strengthened.

15 image (on tracing paper) with anatomical topographical landmarks of the head in the photograph c. R., the diameter of the image of the iris of the right eye is adjusted to 4.0 mm. By repositioning the skull, the diameters of the iris, the contours and the anatomical and topographical landmarks of the face and the skull on the camera's opaque glass are combined.

25 Photograph in the specified position and scale of the skull.

Negatives of the face and skull, captured on the film in the same perspective and scale, are combined by imposing

30 at each other on the negatoscope, paying attention to the coincidence of contours and anatomical and topographical landmarks.

Using the iridial test (IT

35 12.1 mm), combined images of the face and skull are enlarged to the full size and projected print transferred onto photo paper.

There is an optimal correspondence between the contours and anatomical and topographical landmarks of the face and the skull, which allows us to speak about the belonging of an intravital photograph c. R. and the detected skull to one person.

METHOD FOR PERSONAL IDENTIFICATION, including photographing the skull in a position corresponding to the position of the head of the identifiable person in his intravital photograph, bringing the images of the skull and head to the same scale, photo-matching of images and comparative research, from. In this case, in order to increase the accuracy of the method, the horizontal diameter of the iris of the eye is used as a scale reference when enlarging the image. C e ate
