The utility model integral type pupil measuring device is easy to equipment and is used in emergency department, desinfection chamber.
As shown in Fig. 2 using the central control system of above-mentioned integral type pupil measuring device, including pupillometry dress
Put, data center and mobile device, carried out by encryption data between described pupil measuring device, data center and mobile device
Wireless telecommunications.Described data center is communicated wirelessly with least two pupil measuring device.Described pupil measuring device with extremely
Few two mobile devices communicate wirelessly.Each pupil measuring device all can distribute measurement data to data center, simultaneously
Each pupil measuring device can actively mate with other mobile devices, sends measurement data to obtaining the mobile device authorizing.
User of service can be in pupil measuring device, data center or the enterprising line number of mobile device it is investigated that seeing and diagnosing.
Data center can analyze pupil rate of change, arranges rate of change early warning, early warning information can be pushed to mutual
The mobile terminal of connection.Edge extracting, the calculating of pupil rate of change are included to the analyzing and processing of pupil data.
The data of described pupil measuring device transmission can be view data, and the data of described pupil measuring device transmission is also
Pupil radium and pupil rate of change can only be included, to reduce data-storing difficulty.System can transmit it in data encryption
Before carry out ultrasonoscopy compression and pupil rate of change compression, be conducive to data transfer and storage.
As shown in figure 3, the measurement analyzing and processing process of pupil mainly includes：Probe signal obtains, Beam synthesis, ultrasonic one-tenth
Picture, edge extracting, radius calculation, pupil rate of change calculates.
Ultrasonic treatment systems in described pupil measuring device utilize ultrasonic probe to scan eyeball, open without person under inspection's active
Widen the view eyeball, or passively break eyelid into two with one's hands and measure, and simply ultrasonic probe is put in eyelid surface, by connecing to echo-signal
Receipts, Beam synthesis and signal transacting and imaging, obtain pupil and other eye structures clearly real-time dynamic ultrasound image.
The post processing of image module of described ultrasonic treatment systems utilizes active contour model (Snake model) rim detection to calculate
Method carries out automatically extracting and measuring of pupil target in eye ultrasonoscopy, and this algorithm is to be minimized based on image integral energy
Curve deformation method.
Snake model algorithm initializes a closed curve first in the picture as the initial profile of pupil target, shape
Shape is arbitrarily it is ensured that this closed curve includes pupil target completely.Described ultrasonic treatment systems provide carrying of two kinds of pupil targets
Delivery formula：Semi-automatic and fully automatic mode.Semiautomatic-mode needs user's the first frame ultrasonoscopy initialization on the touchscreen
The approximate location of pupil and scope, within the scope of pupil is completely included here.Fully automatic mode user need not any operate, and is
System obtains the average shape of profile according to the pupil profile of previous acquired images, is automatically positioned the pupil position in present image,
Draw first closure curve.
Build the energy equation of Snake model, several control points are selected on closed curve, make full use of image letter
The flatness of breath, outer limit and curve and continuity define an energy equation, and energy equation is made up of two parts：Specification is bent
Wire shaped smooths and continuous self-energy, and weighs the outer energy near objective pupil edge degree.The mistake of detection pupil edge
Journey minimizes energy equation, so that curve is constantly internally tightened and keep smooth, on the other hand ensures that curve is received
Hold back to objective pupil edge.
The Eulerian equation representing curve control point stress is calculated according to constructed energy equation, according to each control point
Stress to curve deformation, until energy equation reach minimum of a value stop.Curve convergence is to pupil edge.
Snake model comprehensively utilizes information and priori in image, thus obtaining a more accurate result, carries
The robustness of high algorithm.This model is an inearized model, is advantageously implemented and calculates in real time, is easy to be applied to described pupil
In the real time processing system of measurement.
In image formed by ultrasonic system, pupil is one piece of dark areas, is usually located at image center, but the eyeball meeting of people
Independently do not rotate, eyeball turns over or skew back all can lead to pupil edge to obscure or pupil ovalisation, so calculating in snake
The left and right footpath of automatic measurement pupil in the pupil image that method is extracted, thus obtain the diameter of pupil on present image.Automatic measurement
The principle of PD is consistent with the method for manual measurement, chooses whole pupil Vertical Square admedian position measurement pupil during measurement
Bore dia.Because ultrasonoscopy is dynamic image in real time, for each two field picture, system all can automatic measurement PD,
Thus trying to achieve the change curve of PD, increase examination information.
The system that is illustrated in figure 4 calculates bent curvature of a curve according to the situation of change of pupil.System can carry out segmentation
Pupil rate of change calculates and measurement is it is also possible to after matching change curve, automatic derivation.
