Embodiment
In order to which the technological thought of the present invention is expanded on further, in conjunction with specific application scenarios, to the technical side of the present invention
Case illustrates.
As shown in figure 1, a kind of safe class method of adjustment provided by the embodiment of the present invention, its subject of implementation is as schemed
Scanning device shown in 2, contained in the scanning device for being scanned necessary probe to images to be recognized.
Before elaborating technical scheme, safe class involved in the present invention is described first below：
For the images to be recognized of the type such as Quick Response Code or bar code, quality and use due to printing quality
During objective condition influence, its own possibly can not be scanned the identification of first time property in certain situation.With prior art
In in for bar code " American Standard detection method " in bar code credit rating exemplified by, different credit ratings indicates bar code
Printing quality and its applicable situation.A levels bar code can be distinguished well, be adapted to only scan along a line and only scan
Occasion once.Performance of the B level bar codes in recognition is not so good as A levels, is suitable for only scanning along a line but allows multiple scanning
Occasion.C levels bar code may need more multiple scanning, generally to use energy multiple scanning and have the equipment of multi-strip scanning line
Relatively good recognition effect could be obtained.D levels bar code possibly can not be distinguished by some equipment, the recognition effect to have obtained, then
To use can multiple scanning and the equipment with multi-strip scanning line.F level bar codes are defective works, it is impossible to are used.
The different credit ratings of images to be recognized represent its probability that can be identified, accordingly, the safety of probe
Grade then represents the scanning standard that the probe is directed to images to be recognized.Wherein, the probe of higher safe class is being schemed
As the requirement in terms of type, the definition of image recognition, the light and shade of ambient light and bar code reading times be higher than it is relatively low
Safe class probe.
By taking the probe used in concrete application scene as an example, safe class is divided into the fourth class in the specific embodiment, etc.
Level more high detection, the standard of identification is higher.Illustrated below by way of the requirement example of four safe classes：
When safe class is 1, probe only can carry out twi-read to a few type bar code, then further decoding, its
Yu Jun is decoded at once after reading；
When safe class is 2, probe can carry out twi-read and then decode to all types of bar codes.
When safe class is 3, probe is checked the environment (bright and dark light etc.) of surrounding first, and confirmation meets general
The bar code of some types can be read three times after standard (standard is relatively low for the advanced standard in safe class 4)
Then further decoding is taken, remaining carries out twi-read.
When safe class is 4, probe is checked the environment (bright and dark light etc.) of surrounding first, and confirmation meets advanced
All types of bar codes can be read three times after standard, then further decoding.
It can be seen that the safe class of probe is higher according to above-mentioned specific example, the requirement, identification to bar code standard are accurate
True rate is higher while also more time-consuming.The lower grade of probe, and the requirement, recognition accuracy to bar code standard are lower, while
Reaction is quicker.Therefore, the bar code of probe recognition failures or the None- identified, (core of such as bar code in addition to bar code self problem
There is damaged, improper bar code etc. in position), safe class is set into one of the reason for too high and important.For example, bar code is not marked
Standard causes the continuous reading result several times to bar code inconsistent or decoding failure.
However, although reducing safe class and suitably relaxing the restriction helps to be lifted the bar code discrimination of scanning device and simultaneous
Capacitive, for nonstandard bar code, if using relatively low safe class, although response speed is quickly, but error code risk is higher.
If occurring same type bar code scan result in actual use, notable difference, same bar code Multiple-Scan result to be present inconsistent

Few once consistent (scanning result is sky more than once)；
(3) scanning device images to be recognized can not be identified by the probe that (probe is direct
Return to miscue).
Step S102：When scanning device safe class set in advance is low, if passing through the scanning scalp acupuncture
The scanning result obtained to images to be recognized is not sky, and during the scanning result the second preparatory condition of satisfaction, heightens described sweep
Retouch the safe class of head.
The situation is low situation in safe class primarily to prevent under lower security grade that scanning result is inaccurate
Under, obtain scanning result and the scanning result meets the second preparatory condition, then obtained by heightening the safe class of probe
Obtain more accurate scanning result.
