Description
Technical field
This utility model relates to a kind of photograph auxiliary device, the particularly a kind of demarcating instrument for deflecting angle of cranium face that can demarcate skull and face X deflection angle when the skull of taking the people and face photo.
Background technology
Skull surface and face the people have corresponding Forensic Anthropology index point, and the corresponding Forensic Anthropology index point of skull surface and face has dependency relation, and according to this dependency relation, the someone proposes to identify the photographic superimposition method of cranium body source.
The photographic superimposition method is to allow the two dimensional image of skull and missing person's photo coincide identify the method for cranium body source by the dependency relation of the Forensic Anthropology index point on the 2-dimentional photo of skull and face.
Identify cranium body source with the photographic superimposition method, study, obtain the dependency relation of Forensic Anthropology index point of the 2-dimentional photo of skull and face.Research, when obtaining the dependency relation of Forensic Anthropology index point of 2-dimentional photo of skull and face, gather the 2-dimentional photo of the skull surface and the face of certain statistical mathematics quantity, on photo, indicate the Forensic Anthropology index point then, measure the data of correlating markings point again, obtain dependency relation after handling by statistics.
Because missing person's photo has different X deflection angles, when identifying cranium body source, to be adjusted to the angle identical to the X deflection angle of skull with the horizontal shooting angle of photo with the photographic superimposition method, again because the Forensic Anthropology index point of skull surface and face is not on same plane, but on people's skull and the male and female face on the face, at different X deflection angles, the dependency relation of the Forensic Anthropology index point of the 2-dimentional photo of skull and face differs greatly, and can only identify with the dependency relation of the Forensic Anthropology index point of the skull surface of this angle and face, so need the dependency relation of Forensic Anthropology index point of the 2-dimentional photo of the skull of a series of varying level deflection angles and face when identifying cranium body source with the photographic superimposition method for the photo of varying level deflection angle.
In order to study, obtain the dependency relation of Forensic Anthropology index point of the 2-dimentional photo of the skull of different X deflection angles and face, will absorb at the skull of different X deflection angles and the 2-dimentional photo of face, when the 2-dimentional photo of skull that absorbs different level angle degree and face, to be placed in camera site before the photographing unit to skull and face by different X deflection angles exactly, Forensic Anthropology index point at the 2-dimentional photo of the skull of the certain statistical mathematics quantity of each X deflection angle collection and face, measure the data of correlating markings point, obtain the dependency relation of Forensic Anthropology index point of the 2-dimentional photo of the skull of this X deflection angle and face after learn handling by statistics, repeat the method, can obtain the dependency relation of Forensic Anthropology index point of the 2-dimentional photo of the skull of a series of varying level deflection angles and face.
When taking people's skull and face photo, can will greatly influence the accuracy of statistical data to people's skull and face by the camera site that X deflection angle is placed in before the photographing unit exactly for above-mentioned purpose.For the correct dependency relation of the Forensic Anthropology index point of the 2-dimentional photo of the skull of studying, obtain the varying level deflection angle and face, will take people's the skull and the 2-dimentional photo of face at X deflection angle accurately.In the prior art, when the 2-dimentional photo of the skull of taking the people and face, can not demarcate people's the skull and the device of face X deflection angle exactly.
