Can not contents of the definition digital display board T1 into T4 before knowledge.It is corresponding after image P is intercepted by image capture unit 11
Image document will be transferred into processor 12.Processor 12 is received after image document, can utilize the word string in data bank 14
Image data is compared with image document, it is intended to all possible word string is picked out in image P, and word string referred herein includes one
Word string more than individual character.And the mode for recognizing word string can perform image document pretreatment (Preprocessing) step
Suddenly, and the noise in image document is removed, conventional mode is two matter after GTG, uses median filter etc..Then will
Possibility word string in image document is cut (Segmentation) and characteristic value access (Feature Extraction)
The step of, direction of framework, external form or pixel comprising word etc., and with the internal memory word string image data in data bank 14 by
One compares.If processor 12 detects some region of characteristic value (Feature) matching word string image data in image document,
Processor 12 can judge that the object in this region is a cognizable word string.However, the mode of present invention identification word string is not limited
In the function that word string identification is realized with above-mentioned step, in other embodiments, word string can also be realized with other modes
The function of identification.
When processor 12 is picked out in image P, corresponding to the numeral 108 in numerical monitor billboard T1, numerical monitor billboard
, will basis after numeral 99 in numeral 52 in T2, the numeral 23 in numerical monitor billboard T3 and numerical monitor billboard T4
Each word string picked out produces corresponding word string identification region, as shown in dashed line in figure 2.This means, digital 108 corresponding words
String identification region R1, the correspondence word string identification of numeral 52 region R2, the correspondence word string identification of numeral 23 region R3, digital 99 corresponding word strings
Recognize region R4.This image P that there is word string to recognize region R1 to R4 is simultaneously back to user interface 10 by processor 12.With
Afterwards, user selects the word string for wanting monitoring to recognize region by user interface 10, and such as user wants to monitor numerical monitor
Billboard T2, will select word string to recognize region R2.Now, user must further set the systems 100 of reminder events and remind
The rule of event.It is exemplified below, it is assumed that the number of user is the queue number shown on No. 63, current numerical monitor billboard T2
For No. 52, and queue number is incremented by over time, now, if the system 100 of the desired reminder events of user shifts to an earlier date 5 numbers and led to
User is reported, user must input a target word string (No. 63) and a predetermined value (5) in user interface 10, and
Word string is set as digital word string and is incremented by with the time.When user is after the completion of the setting of user interface 10, processor 12 can be every
The monitoring picture that region R2 is recognized comprising word string is captured every a scheduled time operation image capture unit 11.The scheduled time determines
Justice is the preset time (one monitoring picture of such as 10 seconds photographs) of the system 100 of reminder events or user in user interface 10
The user's custom time inputted.And the monitoring picture that the scheduled time of the present invention can be captured with image capture unit 11
The average period of word string change dynamically adjust, and will be described in detail with rule after the step of adjust.
When processor 12 can be captured every a scheduled time operation image capture unit 11 region R2 is recognized comprising word string
Monitoring picture after, processor 12 can carry out it is similar it is foregoing identification word string the step of, the word string image in data bank 14, by
The monitoring word string that correspondence word string recognizes region R2 is picked out in monitoring picture.The step can be repeatedly every a scheduled time
Carry out.Because the numeral shown on numerical monitor billboard T2 can be incremented by over time, the system 100 of reminder events will be in one
Individual reasonable time point performs event notification functions, and such as Fig. 3 time flow chart is represented.In figure 3, the target that user defines
Word string SPFor No. 63, the number for representing user is No. 63.The predetermined value D that user defines is 5, represents that user is intended to allow and carries
The system 100 for the event of waking up is in target word string SP5 numbers note that and (imply that and noted that more than or equal to No. 58) before.In figure 3,
The system 100 of reminder events is in after time point P1, the monitoring word string S picked out by monitoring picture1For No. 54, because be not more than etc.
In No. 58, the system 100 of reminder events can't perform event notification functions.In broad terms, in figure 3, reminder events is
If the number range of monitoring word strings 52 to 57 that system 100 is picked out in monitoring picture, the systems 100 of reminder events is all without holding
Row event notification functions.After the system 100 of reminder events is in time point P2, the monitoring word string S picked out by monitoring picture2For
No. 58, because monitoring word string meets the rule more than or equal to No. 58, the system 100 of reminder events will perform event notification functions.
In broad terms, if the number range for the monitoring word string more than 58 that the system 100 of reminder events is picked out in monitoring picture, remind
The system 100 of event will perform event notification functions.
If the number on numerical monitor billboard T2 successively decreases over time, the systems 100 of reminder events also can be used for number with
In the queuing situation that the time of wearing successively decreases.For example, the target word string S that user definesPFor No. 63, the number of user is represented
For No. 63.The predetermined value D that user defines is 5, represents the system 100 of user's reminder events to be allowed in target word string SPIt
Preceding 5 numbers note that and (imply that and noted that less than or equal to No. 68).In that case, the system 100 of reminder events is in monitoring
If number range of the monitoring word string more than 68 that image identification goes out is (for example：73rd, 72,71,70,69), the system of reminder events
100 can't perform event notification functions.If the system 100 of reminder events is less than in the monitoring word string that monitoring picture is picked out
Number range equal to 68 is (for example：68th, 67,66,65,64,63), the system 100 of reminder events will perform event notification functions.
Therefore, if predetermined value D is defined as 0 by user, represent the system 100 of user's reminder events to be allowed in mesh
Marking-up string SPWhen being same as the monitoring word string that monitoring picture is picked out, the function of reminder events is just performed.Although above-described embodiment
In, the word string that the system 100 of reminder events is recognized is not limited for digital word string, but the present invention, in other embodiments
The word string that the system 100 of reminder events is recognized can be alphabetical word string, in that case, user in user interface 10 only
Target word string S need to be inputtedP, it is not necessary to input predetermined value D information (because alphabetical word string does not have computing).Reminder events
The monitoring word string that is picked out in monitoring picture of system 100 be same as target word string SPWhen, just perform the function of reminder events.
Here it will be described in the system 100 of the reminder events of the present invention, processor 12 can be every a scheduled time behaviour
Make image capture unit 11 and capture the monitoring picture that region R2 is recognized comprising word string, and the scheduled time can be with image capture unit
The step of average period of the word string change of 11 monitoring pictures captured dynamically adjusts.This step is described with an example herein
Suddenly, user interface 10 of the user first in the system 100 of reminder events sets the scheduled time as A seconds (however, this is pre-
Fixing time can fix time for the interior of the system 100 of reminder events, it is assumed that be A seconds).The system 100 of reminder events is every to pass through shadow in A seconds
As capture device 11 captures monitoring picture, it is assumed that captured N monitoring pictures, spent (N × A) second, N is positive integer.And at this
(N × A) in the second, the change that monitoring word string (numeral) is picked out in N monitoring pictures of the observation of processor 12 turns to Q1To Q2, for example by
52 change to 56.Now, in order to more efficiently capture monitoring picture, processor 12 scheduled time will be adjusted to close to (N ×
A)/|(Q1-Q2) | the second is to capture image.Supervised for example, the system of reminder events is captured for 100 every 10 seconds by image capture unit 11
10 monitoring pictures have been shone in visible image, cost for 100 seconds.And in this is 100 seconds, processor 12 is observed in 10 monitoring pictures and recognized
Go out to monitor the change of word string (numeral) to be changed to 56 by 52.Now, in order to more efficiently capture monitoring picture, processor 12 will
Can be adjusted to the average period close to monitoring word string (numeral) change of 100/4 second (i.e. 25 seconds) scheduled time.However, because
Processor dynamically adjusts acquisition picture frequency, therefore the system of reminder events of the present invention according to the monitoring picture of preceding N at any time
100 average period changed according to the word string of monitoring picture can be considered a movement the step of dynamically adjustment captures picture frequency
Calculating operation average method (Moving Average Algorithm), and the time interval of the N monitoring pictures for calculating can be considered
The interval of sliding window (Moving Window).
In summary, the invention provides a kind of system of reminder events and the method for reminder events, its idea is profit
