Fixed terminal.
The safety alarming method based on car networking of the embodiment of the present invention can be filled by the security alarm based on car networking
100 execution are set, the safety alarm device 100 based on car networking can be installed on car, such as automobile, rail vehicle etc., be based on
The safety alarm device 100 of car networking may include above-mentioned acquiring unit 106, on-vehicle host 107.
As shown in Fig. 2, the safety alarming method based on car networking includes the following steps:
Step S10 obtains the number of interior occupant and the behavior image of occupant.
In the present embodiment, the number for obtaining interior occupant and the behavior image for obtaining occupant can carry out simultaneously, obtain
The number of occupant in pick-up and the behavior image for obtaining occupant can be held by being set to the interior same acquiring unit 106
Row, in specific execute, the contour images and behavior image of the available occupant of interior camera.
In actual execution, the number for obtaining interior occupant includes: that the number of occupant is obtained by recognition of face；Or
Person, the number for obtaining interior occupant include: that the number for obtaining occupant is identified by human body contour outline.
In actual execution, the behavior image for obtaining interior occupant includes: the row that occupant is obtained by image recognition
For image.
In application scenes, remote terminal 202 can be directly aobvious by above-mentioned acquiring unit 106 (such as camera)
Show or shoot the image information of interior occupant.
Step S20 determines the behavior of occupant based on image recognition model trained in advance when the number of occupant is greater than 1
The similarity of image and known act of violence image.
It is understood that act of violence is that a side applies another party, and when the number of occupant is greater than 1, act of violence
It is likely to occur.
Safety alarm device 100 can obtain preparatory trained image recognition mould from cloud server 200 by network
Type, certainly, the image recognition model can also be stored in safety alarm device 100 in advance.
In application scenes, above-mentioned image recognition model can update beyond the clouds, and safety alarm device 100 can be with every
Above-mentioned trained image recognition model is obtained from above-mentioned cloud server 200 by network every the predetermined time.

In image recognition model, which can determine the behavior image and known act of violence image of above-mentioned occupant
Similarity.
In actually executing, above-mentioned steps S20 may include following sub-step:
Sub-step S21 extracts the behavioural characteristic of occupant in subordinate act image.
Above-mentioned image recognition model can extract the behavioural characteristic of passenger from the behavior image of above-mentioned passenger.Above-mentioned behavior
Feature can include but is not limited to following characteristics: the movement speed of occupant, the limbs in the movement of one of occupant with it is another
The distance of a occupant, the tool shape in occupant's hand, the expanded angle of the limbs of occupant and shape etc..
Sub-step S22, behavioural characteristic based on occupant and the behavior extracted from known act of violence image in advance
Feature determines the behavior image of occupant and the similarity of known act of violence image
In the present embodiment, above-mentioned cloud server 200 is in the known act of violence image of use to upper image recognition mould
When type is trained, the behavioural characteristic of each movement can be extracted from the various conventional infringement movements being pre-designed.Above-mentioned peace
Full warning device 100 is available above-mentioned to have mentioned when obtaining above-mentioned image recognition model from above-mentioned cloud server 200
The behavioural characteristic of your movement of each armful taken.
In this way, above-mentioned image recognition model determines that the behavior image of occupant and the similarity of known act of violence image can
To be converted into the similarity for the behavioural characteristic extracted in the above-mentioned behavioural characteristic and known act of violence image of determining passenger, this
One infringement movement can be split as multiple behavioural characteristics by sample, comprehensively considered the similarity of multiple behavioural characteristics, avoided identifying
Error.
Step S30 determines whether car occurs incident of violence according to similarity.
In the present embodiment, for any one interior occupant, above-mentioned safety alarm device 100 can be according to the occupant
Behavior image and the similarities of behavior image of a variety of violent actions interior whether incident of violence occurs to determine.
Specifically, when the behavior image of the passenger and a kind of known similar example of the behavior image of violent action are greater than in advance
If when similarity threshold, can determine that the passenger is the personnel that exert violence.Otherwise, it can determine that the passenger is not the personnel of exerting violence.
Step S40, however, it is determined that incident of violence occurs for car, then sends prompt information.
In the present embodiment, it when step S40 determines interior incident of violence, can be sent to the remote terminal 202 of setting
Prompt information, above-mentioned prompt information may include image information perhaps image information check link or current vehicle position
It sets.
In application scenes, step S40 may include following sub-step:
To the remote terminal 202 of setting prompt information occurs for sub-step S41.
In the present embodiment, after remote terminal 202 receives the prompt information, violence occurs really by judging whether again
Movement, can choose alarm.
In application scenes, remote terminal 202 may include the mobile phone of certain kith and kin, which receives the prompt information
Afterwards, by the link of prompt information, image information is checked, it can be determined that whether violence power is occurring really, if it is, can
To select alarm.
Sub-step S42, however, it is determined that incident of violence occurs for car, then carries out image coding, and the image information of occupant is sent
It is stored to cloud.
In the present embodiment, with reference to Fig. 1, the image that safety alarm device 100 can also will acquire uploads after encoding in detail
It is stored to cloud, accordingly even when vehicle is damaged can also provide the evidence of infringement by the backup in cloud, and cloud storage
