Analysis processes and draws the operational order needing to perform, then the display content corresponding to this operational order is delivered to described
Touch screen 2 shows.
The end of described probe and described main frame is for removably connecting, thus it is replaceable to pop one's head in.
Described main frame is provided with wireless charging device so that integral type pupil measuring device can carry out wireless charging.
Described main frame is provided with face recognition device, fingerprint identification device and iris identification device at least within
One of.This system is before carrying out the measurements, it is possible to use the modes such as shape of face, fingerprint or iris identification are entered
Row patient information record.
Integral type pupil measuring device of the present invention is easy to equipment and is used in emergency department, sterilizing room.
As in figure 2 it is shown, use the central control system of above-mentioned integral type pupil measuring device, including pupil
Measurement apparatus, data center and mobile device, described pupil measuring device, data center and mobile device it
Between communicated wirelessly by encryption data.Described data center and at least two pupil measuring device carry out nothing
Line communication.Described pupil measuring device communicates wirelessly with at least two mobile device.Each pupillometry
Device all can distribute measurement data to data center, the most each pupil measuring device can actively and other
Mobile device is mated, and sends measurement data to obtaining the mobile device authorized.User of service can survey at pupil
Amount device, data center or the enterprising line number of mobile device be it is investigated and seen and diagnose.

The stress at control point is to curve deformation, until energy equation minimizes value and stops.Curve convergence is to pupil limit
Edge.
Information in Snake model comprehensive utilization image and priori, thus obtain one and tie the most accurately
Really, the robustness of algorithm is improved.This model is an inearized model, is advantageously implemented and calculates in real time,
It is easy to be applied in the real time processing system of described pupillometry.
In image formed by ultrasonic system, pupil is one piece of dark areas, is usually located at image and hits exactly, but people
Eyeball can not independently rotate, and eyeball turns over or skew back all can cause pupil edge fuzzy or pupil becomes ellipse
Shape, so automatically measuring the footpath, left and right of pupil in the pupil image that snake algorithm extracts, thus is worked as
The diameter of pupil on front image.Automatically the principle measuring pupil diameter is consistent with the method for manual measurement, measures
Time choose whole pupil Vertical Square admedian position measurement pupil diameter.Owing to ultrasonoscopy is Real-time and Dynamic
Image, for each two field picture, system all can measure pupil diameter automatically, thus tries to achieve pupil diameter
Change curve, increases 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 be carried out
The pupil rate of change of segmentation calculates and measures, it is also possible to after matching change curve, automatic derivation.
