Driver's image in S22, interception image frame；
S23, judge whether driver's image is consistent with the violation image in setting database；
If S24, driver's image are consistent with the violation image in setting database, driver's image and setting are obtained
The continuous frame number of violation image unanimously in database；
S25, the violation time is obtained according to continuous frame number；
S26, judge whether the violation time is more than setting time；
S27, if so, obtaining the consistent corresponding unlawful practice of violation image, form message packet output；
If driver's image and the violation image in setting database are inconsistent, S21 steps are returned.
To S27 steps, processor is handled and is identified to picture frame above-mentioned S21 steps, to driver's image and number
It is compared one by one according to the violation image stored in library, it specifically, can be by the image segmentation of the two at several small lattice, often
A small lattice compare one by one, obtain likelihood, recycle the mode of weighted sum, obtain the similar overall rate of two images, are more than
The similar overall rate of given threshold then shows that two images are consistent.
Further, above-mentioned S3 steps, the step of scoring in real time according to driving situation, including in detail below
Step：
S31, according to unlawful practice, obtain driver reduces score；
S32, score is driven according to driver upper one and currently reduces score, obtain driver's present score.
For example, if the unlawful practice time is more than 5min, it is more than that each unlawful practice has weight to be considered as, profit
It is multiplied by weight with the time, score is reduced in formation.
Unlawful practice is quantified, driver can be made more to understand that the light of itself unlawful practice with again, drives vehicle
It sails for people, is conducive to cultivate good driving habit, reduces property loss；It, can be more fully for insurance company
Risk indicator is assessed, more accurately estimated amount of damage can be brought, its cost of settling a claim is substantially reduced, in addition, can also promote client's
