As shown in fig. 2, a method for processing a block chain-based vehicle video according to an embodiment of the present invention includes:
step 210, acquiring at least one piece of vehicle-mounted video information at preset time intervals.
Specifically, the vehicle-mounted video information is video information shot by a vehicle-mounted camera on a vehicle, for example, the vehicle-mounted camera is a vehicle-mounted monitoring camera, the vehicle-mounted camera can shoot road conditions in front of a running road of the vehicle, at the moment, the vehicle-mounted camera is used as a vehicle recorder, and the vehicle-mounted camera can shoot the situation in a carriage. In this embodiment, the vehicle-mounted video information is acquired and then uploaded at intervals, so that the total data volume can be effectively reduced, and network blocking is avoided.
For example, the time nodes for acquiring the vehicle-mounted video information of different vehicles are different, so that the vehicle-mounted video information can be uploaded at different time nodes for different vehicles, network congestion caused by large data volume can be effectively avoided, and the load of each node is effectively reduced.
In one embodiment, at least one in-vehicle video information is acquired at preset intervals when a trigger event is detected. In this embodiment, the triggering event is a preset event capable of triggering uploading of the vehicle-mounted video information, and the event indicates that the road condition of the vehicle running at the moment is bad or the running state of the vehicle is bad, and then the vehicle-mounted video information is triggered to be acquired and uploaded at the moment, so that the situation of the vehicle in the case of bad road condition or bad running state can be effectively recorded.
Step 220, obtain vehicle information.
In this embodiment, the vehicle information includes vehicle identification information, which is a unique identification of the vehicle, for distinguishing between different vehicles. In this embodiment, the source of the in-vehicle video information can be located by the vehicle information. In one embodiment, the step includes obtaining the vehicle information and the current time, and the time node of the positioning vehicle-mounted video information to be uploaded can be obtained by obtaining the current time.
And step 230, associating the vehicle information with the vehicle-mounted video information, and broadcasting the associated vehicle information and the associated vehicle-mounted video information to other nodes of a blockchain.
In this embodiment, the vehicle information and the vehicle-mounted video information are associated so that a corresponding relationship is established between the vehicle information and the vehicle-mounted video information, so that a plurality of vehicle-mounted video information can be respectively corresponding to different vehicles.
In this embodiment, the nodes of the blockchain are composed of a plurality of computer devices on the vehicle, where the computer devices on the vehicle are intelligent gateways on the vehicle, and may also include a server, where the computer devices on the vehicle and the server compose each node of the blockchain, and each node can store a block of the blockchain. Each node broadcasts the associated vehicle information and the vehicle-mounted video information of the current vehicle so that other nodes can receive the associated vehicle information and the vehicle-mounted video information broadcast, a block is generated based on the mining principle of the block chain, and the node which generates an effective block at the earliest time inputs the effective block chain into the block chain, so that the block chain is updated.
In the above embodiment, by broadcasting the vehicle-mounted video information and the vehicle information, other nodes of the blockchain can receive the vehicle-mounted video information and the vehicle information, and further, one of the nodes can package the vehicle-mounted video information and the vehicle information broadcast to generate a block and link the block into the blockchain, so that the vehicle-mounted video information can be stored in the blockchain; the distributed storage of the vehicle-mounted video information is realized through the block chain, so that the vehicle-mounted video information is not easy to tamper, and the storage of the vehicle-mounted information is more efficient and safer.
In one embodiment, the method of blockchain-based on-board video processing further comprises: receiving the associated vehicle information and the vehicle-mounted video information; generating a block containing the associated vehicle information and the in-vehicle video information based on the associated vehicle information and the in-vehicle video information; the block is added to the blockchain.
Specifically, a blockchain is a shared database through which blocks store data or information, with blocks in the blockchain being formed by the packaging of nodes joining the blockchain. In this embodiment, since each node in the blockchain is capable of receiving broadcast information sent by other nodes, when receiving the associated vehicle information and the vehicle-mounted video information broadcast by other nodes, the associated vehicle information and the vehicle-mounted video information are packaged to generate a block, and the blockchain is imported into the blockchain, so that the blockchain is updated. It is worth mentioning that, because each node is performing calculation, the block generated by the node with the earliest successful mining is the effective block based on the mining principle of the blockchain.
It should be understood that the blocks of the blockchain are generated by the nodes distributed in the network, and the blocks of the blockchain are recorded and updated by the nodes in the network, so that the on-vehicle video information is stored in a distributed manner without a server, occupation of server resources can be effectively reduced, the on-vehicle video information can be recorded more reliably, tampering is effectively avoided, and since each node can independently store the blockchain, reading efficiency of the second user identification information can be effectively improved, and thus acquisition efficiency is improved.
In one embodiment, the step of generating a tile containing the associated vehicle information and the in-vehicle video information based on the associated vehicle information and the in-vehicle video information comprises: acquiring current time and generating a time stamp according to the current time; based on the associated vehicle information and the in-vehicle video information, generating a block containing the associated vehicle information and the in-vehicle video information according to the time stamp.
In this embodiment, the time stamp records the generation time of the block. It should be noted that, since each node in the blockchain performs mining after receiving the associated vehicle information and the vehicle-mounted video information, the mining time of each node is different, and the generated block can be acknowledged by other nodes for the node which firstly claims to finish mining, by recording the time stamp, when a plurality of nodes generate blocks, one block can be determined to be an effective block, and the time of the time stamp of the effective block is earliest.
It should be noted that, the node for generating a block according to the associated vehicle information and the on-board video information may be a current node, or may be another node in the blockchain that receives the broadcast associated vehicle information and the on-board video information, for example, the node may also be a server.
It should be understood that, for the vehicle information and the on-vehicle video information generating node according to the association, the implementation principle is the same as that of the generation of the block of the existing blockchain, for example, the block header information of the latest block in the blockchain is obtained, the hash operation is performed according to the block header information, the block header information of the current block is obtained, and the associated vehicle information and the on-vehicle video information are written into the block header of the block to generate the block. Each node will perform the operation of generating a block and for the node that generated the current block earliest, that node will be successfully linked into the blockchain. That is, each node "mines" based on the broadcasted associated vehicle information and the on-board video information, respectively, and for a node that successfully "mines", its generated block is then linked into the blockchain. In this way, each node has the opportunity to enter the block chain generated by each node into the block and update the block chain, so that the associated vehicle information and the vehicle-mounted video information are stored in a distributed mode.
In one embodiment, the step of associating the vehicle information with the in-vehicle video information and broadcasting the associated vehicle information and in-vehicle video information to other nodes of a blockchain includes: associating the vehicle information with the vehicle-mounted video information, and broadcasting the associated vehicle information and the associated vehicle-mounted video information to other nodes of a blockchain; after the associated vehicle information and the vehicle-mounted video information generation block are merged into a block chain, indication information corresponding to the vehicle information and the vehicle-mounted video information is generated; broadcasting the indication information to other nodes of the blockchain.
In this embodiment, the indication information is used to indicate the associated vehicle information and the vehicle-mounted video information, and indicate the time and the block that the vehicle information and the vehicle-mounted video information are broadcast, so that after the indication information is broadcast to other nodes, the other nodes can package the indication information to generate the block, when the associated block corresponding to the vehicle information and the vehicle-mounted video information needs to be obtained, the block where the indication information is located can be analyzed first to obtain the indication information, and the associated block corresponding to the vehicle information and the vehicle-mounted video information is determined according to the indication information, so that the associated block corresponding to the vehicle information and the vehicle-mounted video information can be found quickly, and the obtaining efficiency of the vehicle-mounted video information in the block chain is effectively improved.
In one embodiment, the method of blockchain-based on-board video processing further comprises: receiving indication information; generating a block containing the indication information based on the indication information; and adding the block containing the indication information to the blockchain.
In this embodiment, when a node receives indication information broadcast by other nodes, a block containing the indication information is generated based on the indication information, and a blockchain containing the indication information is imported into the blockchain, so that the blockchain is updated, and the blockchain records the indication information, thereby effectively improving the acquisition efficiency of the vehicle-mounted video information in the blockchain.
In one embodiment, the vehicle information includes at least: vehicle speed information, position information, engine torque information, engine speed information, and vehicle identification information.
In this embodiment, the vehicle information includes not only the vehicle identification information, but also the vehicle speed information, the position information, the engine torque information and the engine rotational speed information, which record the current running state of the vehicle and reflect the road conditions, for example, whether the vehicle is in a climbing state, a downhill state or is running on a level road at this time can be calculated according to the vehicle speed information, the engine torque information and the engine rotational speed information, and the position and the altitude where the vehicle is located at this time can be determined according to the position information. For example, the vehicle speed information, the engine torque information and the engine rotation speed information can be obtained through a driving computer of the vehicle, for example, the position information is GPS (Global Positioning System ) position information, and can be obtained through a GPS module. It should be understood that, in general, when an accident or accident occurs in a vehicle, abnormality occurs in correspondence of vehicle speed information, position information, engine torque information, and engine speed information with each other, and then the occurrence of the accident or accident can be determined. Through the information corresponding to the running state of the vehicle, the vehicle-mounted video information can be corresponding, so that the running state of the vehicle and the vehicle-mounted video information can be recorded in the blockchain, the state of the vehicle and the monitoring video can be recorded conveniently when the vehicle has an accident or accident, and the evidence collection after the accident is facilitated.
In one embodiment, before the step of acquiring at least one in-vehicle video information at preset time intervals, the method further includes: and acquiring the vehicle-mounted video information, and storing the vehicle-mounted video information in a local memory.
In this embodiment, the local memory is a memory disposed on a vehicle, and after the vehicle-mounted video information is acquired, the vehicle-mounted video information is stored in real time in the local memory, so that the vehicle-mounted video information is not only stored in each node but also stored in the local memory, and because the local memory has the advantage of fast storage speed, the vehicle-mounted video information can be quickly stored, and the vehicle-mounted video can be stored in full quantity, so that the storage of the vehicle-mounted video information is more comprehensive.
In one embodiment, the vehicle information includes vehicle state information including vehicle speed information, engine torque information, and engine speed information, and road condition information including position information, altitude information, and hill climbing information.
In one embodiment, the blockchain-based on-board video processing method further includes: the vehicle state information and the road condition information are input into the deep neural network model for learning, for example, the vehicle state information and the road condition information of the vehicle during normal running and abnormal running or failure and accident occurrence are input into the deep neural network model for learning, the vehicle state information and the road condition information corresponding to the vehicle during abnormal running or failure and accident occurrence are obtained, and the vehicle state information and the road condition information corresponding to the vehicle during abnormal running or failure and accident occurrence are output as preset conditions.
In this embodiment, through learning of the deep neural network model, the deep neural network model can analyze vehicle state information and road condition information corresponding to the abnormal running of the vehicle or the occurrence of a fault and an accident, or analyze vehicle state information and road condition information corresponding to the abnormal running of the vehicle or the occurrence of the fault and the accident, so that an intelligent gateway on each vehicle can detect the abnormal state of the vehicle and timely broadcast vehicle-mounted video information.
In one embodiment, the step of acquiring at least one in-vehicle video information at preset intervals includes: and detecting whether a trigger event occurs, and acquiring at least one piece of vehicle-mounted video information at preset intervals when the trigger event is detected.
The step of detecting whether a trigger event occurs comprises the following steps: detecting whether the vehicle state information and the road condition information of the vehicle accord with preset conditions, and determining that a triggering event is detected when the vehicle state information and the road condition information accord with the preset conditions.
Thus, when the vehicle state information and the road condition information meet the preset conditions, the condition that the vehicle is about to enter an abnormality, a fault or an accident is indicated, and therefore, the fact that a trigger event is detected is determined, one piece of vehicle-mounted video information is acquired at intervals, the acquired vehicle-mounted video information and the vehicle information are associated, and the vehicle-mounted video information and the vehicle information are broadcasted. It should be understood that in this step, the vehicle-mounted video information may be obtained by reading from a local memory, or may be obtained by capturing with a camera in real time. Therefore, when the emergency occurs to the vehicle, the vehicle-mounted video information is broadcasted and stored in the blockchain, so that the effectiveness and timeliness of the video can be effectively protected, the loss of the video information is avoided, the uploading and broadcasting of a large amount of video data are avoided, and the network congestion is avoided.
