Problems solved by technology

It often cannot reflect the real and objective color change, thus affecting the accuracy of identification
Therefore, it is very necessary to standardize, standardize and digitize the color judgment involved in the forensic identification process; at the same time, the environment of forensic identification often changes, sometimes indoors, sometimes outdoors, and the light, temperature, and surrounding environment cannot be controlled. At the same time, it is affected by the difference in the equipment used for image acquisition and the difference in the method of use
Therefore, it is difficult to control the formation of uniform shooting conditions

Embodiment 1

[0037] Such as figure 1 shown

[0038] A color recognition method in forensic identification, comprising the following steps:

[0039] S1: Use the standard color card as a reference to shoot in the same frame as the target recognition area in forensic identification; the standard color card refers to the difference caused by the reference calibration environment and equipment, and the standard color card can be accompanied by corresponding changes in the environment and photographic equipment ; The standard color card and the target recognition area are photographed in the same frame to obtain at least three groups of photographed images in the same frame;

[0040] S2: Restore the numerical parameters of the standard color card in the image shot in the same frame; the numerical parameters of the standard color card in the image shot in the same frame are restored by the standard color card.

[0041] S3: Based on the numerical parameters of the standard color card, analyze th...

Embodiment 2

[0048] Color-related forensic information analysis system in forensic identification;

[0049] The color-related forensic information analysis system includes:

[0050] Data collection module: used to obtain the image information of the target recognition area in the standard color card and forensic identification;

[0051] Color correction module: used to calibrate the numerical parameters of the standard color card in the image taken in the same frame and restore the numerical parameters of the standard color card;

[0052] Color recognition module: Use the obtained standard color card numerical parameters to compare and identify the image of the target recognition area to determine the real color data; accurately identify the color of the target area to achieve the purpose of standardization and standardization;

[0053] Cloud database module: build relevant forensic parameters calculation models and databases based on known, standard, and traceable research data; build in...

Embodiment 3

[0063] Application of color recognition method in forensic identification and color-related forensic information analysis system in forensic identification color identification and information analysis;

[0064] Take corpse spots as an example:

[0065] Corpse plaque is an important corpse phenomenon in forensic pathology, which is of great significance for inferring the time of death and the cause of death. Corpse plaque refers to the phenomenon that the blood of the dead body falls and accumulates in the uncompressed blood vessels in the lower part due to gravity, and the skin presents colored plaques there, and the skin appears purple or dark red through the skin. After death, due to the absence of blood pressure, blood gradually accumulates, and corpse plaques gradually appear in the lower unpressed parts of the body, and the color of corpse plaques will deepen with time in the early stage. Moreover, different colors of corpse spots reflect different causes of death, for ...

Abstract

The invention discloses a color identification method in forensic identification. The method comprises: taking a standard color card as a reference to carry out same-frame shooting with a target area in forensic identification; identifying the parameter change of the standard color card image shot in the same frame and sampling the effective area of the target area image; restoring and correcting the color parameters of the standard color card through the attribute change of the image parameters of the standard color card to obtain color change parameters of the standard color card; and analyzing the color of the target area in the commonly shot image, defining the color of the target area by using the standard color card numerical value parameter, and accurately restoring and describing the real color of the target area. A standard color card is utilized to correspondingly change along with the environment and camera equipment, then an intelligent color identification system is utilized to analyze an image and restore a color card value, image color value restoration is performed by taking the standard color card value as a reference, color identification is performed on a target area, and the color of the target area is accurately described; and meanwhile, the target area is analyzed, and important forensic medicine information is extracted.

Description

technical field [0001] The invention relates to the technical field of forensic identification, in particular to a color recognition method in forensic medicine and an intelligent analysis system for color-related forensic information, so as to realize the standardization and intelligence of forensic identification. Background technique [0002] Forensic identification is the inspection and identification of living bodies, corpses and biological evidence related to the person by using the knowledge of medicine, biology, anthropology, physics, chemistry, etc., so as to determine the time of injury, time of death, cause of death, degree of injury, etc. Make judgments and issue concluding opinions. The forensic identification conclusion is an important type of evidence in the three major litigation laws. Because it is closely related to the person, the forensic identification is of great significance in litigation and non-litigation activities. It is an important basis for asc...
