Description
Technical field
The present invention relates to science and technology concerning criminal matters, specifically integrated trace bloodstains are imaged and leave time series analysis dress
Put.
Background technology
Blood stain leaves the time really surely for the deduction of crime time plays an important role.The formation time of blood stain can be helped
Help investigator to obtain more case relevant informations, and exclude with the unrelated bloodstain of case.
Existing blood is left time series analysis method and is mainly carried out in terms of the physicochemical property and chemical composition two of blood stain：
Live blood stain is extracted, RNA analysis, high performance liquid spectrum, near-infrared spectra, uv-vis spectra, reflection is then carried out
Spectrum and high spectrum image etc..But the analysis of chemical composition is limited by experiment condition.
The chemical analysis method that existing blood leaves the time can not be implemented in conventional field.And existing blood stain into
As system can not be analyzed and infer to the formation time of blood stain again.At present yet there are no on blood leave time reckoning dress
The report put.
The content of the invention
Time series analysis device is imaged and leaves it is an object of the invention to provide a kind of integrated trace bloodstains.It can be simultaneously
The imaging and formation time for carrying out blood stain are inferred；It is simple structure, easy to use, using not limited by place.
Concrete technical scheme is as follows：It includes casing, illuminating lamp, mobile phone fixed column, mobile phone, blood stain placer, its feature
It is：Built with formation of foam bubble chamber, illuminating lamp is annular LED bulb to casing, is fixed on the top of casing, and mobile phone is fixed
Post is fixed on the center of the annular LED bulb in casing, and case top is provided with aperture and fixed mobile phone, and blood stain placer is in casing
The center of body bottom.The imaging aperture of case top is 1 with the ratio of camera bellows depth:15-1:20.The colour temperature of LED bulb is
6500k.Mobile phone camera is more than 12,000,000 pixels.
It is an advantage of the invention that：Trace bloodstains can be carried out with real-time, quick analysis in scene of a crime, while to experiment bar
Part is less demanding, and basic unit legal medical expert possesses a portable field blood stain time apparatus for predicting, you can when carrying out live blood stain and carrying out
Between infer, to it is quick, efficiently fight crime and play good impetus.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is mobile terminal analysis system block diagram.
In figure：1 is casing, and 2 is annular LED bulb, and 3 is mobile phone fixed column, and 4 is blood stain placer, and 5 is mobile phone.
Specific embodiment
Casing 1 is annular LED bulb built with formation of foam bubble chamber, illuminating lamp 2, is fixed on the top of casing 1；Hand
The fixed column of machine 5 is fixed on the center of the annular LED bulb in casing, center of the blood stain placer in casing body bottom.Chest 1 is pushed up
The imaging aperture in portion is that ratio is 1 with the ratio of camera bellows depth:15-1:20.
We are connected to imaging system and data processing and computing system on the top of camera bellows.By by standardized blood stain
Photo carries out mathematical analysis, extracts actual parameter, and calculate according to formula fitting.
We determine the optimal proportion in imaging aperture and camera bellows depth by experiment repeatedly, 1:15-1:20 ratio models
Enclose interior optimal.The relevant issues such as illuminating projection, image-capture field can be effectively eliminated in the range of this.
The size of foam casing 1 is advisable in 27.5cm × 17cm × 17cm, can adjust as needed.Built-in cold annular
LED lamp bulbs are using Foshan production, power 12w, colour temperature 6500k.Case top is provided with aperture and fixed mobile phone, and mobile phone is taken the photograph
As head（12000000 pixels）Shot through aperture.
The illumination component that the present invention is used is annular LED bulb, there is provided ring illumination light beam, and its width can ensure to cover
The whole width of lid blood stain and cassette bottom, its length can ensure to cover the whole length of blood stain and cassette bottom.If only using linear
Lighting lamp group, then can form shade, the extraction of affecting parameters in the backlight side of blood stain.
Portable field blood stain time apparatus for predicting is fixed on target blood stain top, and it is portable existing to be in target blood stain
Field blood stain time apparatus for predicting bottom center position.System chassis are placed in the surface in blood stain region, System Computer when system works
Case is blinded by interference illumination of most of ambient light for blood stain, coordinates the use of annular LED light source so that image-forming condition is relatively passed
System method is greatly improved, and image, signal to noise ratio obtain effectively lifting.
Portable field blood stain time apparatus for predicting carries smart mobile phone carries out extraction of taking pictures.
Smart mobile phone carries " the blood stain elapsed time based on smart mobile phone intelligently infers expert decision-making accessory system " software
Intelligent analysis are carried out to extracted target blood stain image, by extracting the critical parameter information in blood stain photo, according to program
Default equation is fitted and analyzes, realize it is objective, rapidly assistant analysis infer the live blood stain elapsed time.
Software is to carry out mathematical analysis by by standardized blood stain photo, extracts actual parameter, and according to formula fitting
Calculate.And Android system mobile phone can be implanted into carry out above-described live blood stain elapsed time and infer, according to mesh of the invention
Can work out.The software systems can be carried out voluntarily with blood stain central point as the center of circle to captured blood stain image, central point
Seven pixels are automatically extracted and substitute into pre-set programs for the circle of radius carries out image in addition, while being manually entered corresponding blood stain
The relevant informations such as blood volume, illumination condition, scene temperature and blood stain carrier.Afterwards, this system data above can be fitted,
Analysis, and fast and accurately provide blood stain elapsed time inferred results.
The base case information process of the automatic receiving terminal view data of system and user input is as follows；
1st, case is filed and is carried out by procedure treatment and phase is extracted for the image for receiving by " blood stain pixel extraction machine "
Close blood stain parameter；
2nd, by calling " blood stain elapsed time analysis model distributor " to carry out Model Matching；
3rd, calling " blood stain elapsed time analysis model " carries out data analysis, while preserving analyze data；
4th, result in 4 is substituted into " blood stain time calculator " finally to draw the blood stain elapsed time automatically, preserves analysis result；
5th, result in 5 is finally shown in terminal device.
