It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.

Example 1

Fig. 1 is a flowchart of a method for associating acquired data of a vehicle-mounted device according to a first embodiment of the present invention, where the method may be performed by an apparatus for associating acquired data of a vehicle-mounted device, and the apparatus for associating acquired data of a vehicle-mounted device may be implemented in hardware and/or software, and the apparatus for associating acquired data of a vehicle-mounted device may be configured in an acquisition system having an apparatus for associating acquired data of a vehicle-mounted device.

As shown in fig. 1, the method includes:

s110, acquiring various video data and various external data of the target vehicle within a preset time length in real time.

Wherein each item of video data includes a video frame and a length of time that matches the video frame.

Wherein, the video data is a video frame in YUV format; specifically, the existing video acquisition methods are divided into two types: acquiring a sensor camera or an AHD camera; on the one hand, for the sensor camera, after receiving the data from the sensor camera, the acquisition system of the embodiment receives the RAW data of the sensor according to the MIPI protocol, calculates and converts the RAW data into a YUV data format; on the other hand, for an AHD camera, the acquisition system firstly converts the A/D analog-to-digital conversion into a YUV format, and then directly receives YUV data according to MIPI protocol.

Further, the external data may be all remaining formats of data that the target vehicle can produce, except video data; by way of example, the external data may be various data such as vehicle speed, steering, gear, gps positioning, and radar from various interfaces such as CAN, UART, I/O.

In this embodiment, each individual video frame is an independent video data, i.e. each item of video data carries only one video frame of known time length.

Further, the time length of the video frame matching can be obtained by a pts (Presentation Time Stamp, display time stamp) time stamp of the video; furthermore, for a video, each video frame forming the video has a pts time stamp to indicate the playing time of the video frame in the video, meanwhile, when playing the video, we need to control the displaying time of each frame according to pts to ensure that the playing speed of the video is matched with the frame rate of the video, and also ensure the synchronization of the audio and the video. The prior art typically uses a frame rate and frame sequence number to calculate a timestamp for each frame; illustratively, if the frame rate of the video is 25fps, the time stamp of the first frame is 0, the time stamp of the second frame is 0.04s (1/25), and the time stamp of the third frame is 0.08s (2/25), i.e., the time length of each video frame is 0.04s relative to the video described above.

S120, filtering the collected video data based on a preset video filtering rule to obtain target video data conforming to the preset filtering rule, and classifying and packaging the external data based on the collection source of the external data to obtain at least one external data packet.

In this embodiment, the preset video filtering rule may be set by the relevant staff according to the actual needs and according to the load of the acquisition system; for example, if the preset video filtering rule is set to be a rule of 1 frame loss per 5 frames, and 25 video data, that is, 25 video frames with a time length, are received in total in a certain period of time, at this time, the collecting system filters the 5 th frame, the 10 th frame, the 15 th frame, the 20 th frame, and the 25 th frame according to the receiving order of each video data when filtering, and takes the remaining 20 video data as each target video data according to the preset filtering rule.

Wherein, based on the collection source of external data carry out classification packing to external data, include: when each external data is acquired, identifying the acquisition source of each external data in real time; wherein the acquisition source comprises: CAN interface, I/O interface, serial port data interface and network data interface; generating a source marking value according to the acquisition source of each external storage data, and carrying out association packaging on each external storage data and the source marking value matched with each external storage data to generate each external data packet. The data recharging system classifies the data according to the source mark value of each video data packet.

For example, in a specific implementation manner of this embodiment, the acquisition system acquires external data in real time through a preset external interface (such as a CAN interface, a UART serial port, an I/O level hard line interface, etc.), where the external data may include data such as a vehicle speed, a gear, a vehicle left-right steering, and gps positioning; after receiving each external data, the acquisition system classifies the data acquired from different interfaces; illustratively, vehicle speed data obtained from the CAN interface is categorized into CAN interface data; the vehicle speed obtained from the GPS is classified as serial interface data; the steering obtained from the I/O is classified as I/O data, and finally, all external data is classified and packaged.

According to the acquisition system, the external data is classified and packed based on the acquisition source of the external data, preparation is made for data recharging work of subsequent work, various data of the equipment end of a vehicle are acquired from which interface during data recharging, recharging is carried out from which interface during recharging, independence and integrity among the external data are guaranteed while various types of data can be acquired from various external ports, various types of data are not mixed during recharging of the acquired data, and establishment of the actual vehicle environment at the time of actual return visit is facilitated.

S130, inputting each target video data into a preset operation model to obtain operation time parameters, frame acquisition time marking values and marking information matched with each target video data, and packaging the operation time parameters, the frame acquisition time marking values and the marking information with the matched target video data to obtain each video data packet.

The operation time parameter can be the calibration parameter of the target video data, the attribute data of the video frames such as a threshold factor and the like; the frame acquisition time stamp value is data for identifying the acquisition time of the current target video data; the marking information is alarm information matched with the target video data, alarm grade state information and the like; further, as known to those skilled in the art, the processing of the video data by the algorithm model to obtain the above information is a mature prior art, which is not described in detail in this embodiment.

And S140, according to the time length and the frame acquisition time mark value in each video data packet, carrying out association packaging on each video data packet and each external data packet according to a preset packaging rule so as to be used for data reading by a data recharging system.

Specifically, in this embodiment, according to the time length and the frame acquisition time stamp value in each video data packet, each video data packet and each external data packet are associated and packaged according to a preset packaging rule, including: sequencing all video data packets according to the acquisition sequence of all video frames in all video data packets, and sequentially acquiring current video data packets according to sequencing results; determining a packaging time period corresponding to a current video data packet according to the time length and a frame acquisition time stamp value in the current video data packet; identifying at least one external data packet acquired in a packaging time period from all external data packets as a target external data packet, and carrying out association packaging on each target external data packet and the current video data packet; and returning to execute the operation of sequentially acquiring the current video data packets according to the sequencing result until the associated packaging processing of all the video data packets is completed.

It is easy to understand that, since each video data is filtered in S120, the corresponding video frame in each video data that is finally packed is discontinuous in time, for example, if the frame rate of the video is 6fps, the timestamp of the first frame is 0, the timestamp of the second frame is 0.04S (1/6), the timestamp of the third frame is 0.08S (2/6), and so on, the timestamp of the fifth frame is 0.16S (5/6), the timestamp of the sixth frame is 0.20S (6/6), if the preset video filtering rule is set to be a uniform rule that 1 frame is lost every 5 frames, and 6 video frames with timestamps are received in total in a certain time, at this time, the acquisition system filters out the 5 th frame according to the receiving sequence of each video data, on the basis of the above, the timestamps in each video frame contained in the packed are respectively 0.04S,0.08S,0.12,0.20S, and the specific length of each video after the time is calculated on the basis of the time stamp: first frame 0.04, second frame 0.04, third frame 0.04, fourth frame 0.08.

It should be noted that, since the external data has no time stamp when received, the external data does not include a time concept, and each video data packet includes a time length and a frame acquisition time stamp value concept, so when the video data packet and the external data packet are associated and packed, at least one external data packet acquired in a packing time period is identified as a target external data packet and is associated and packed with a current video data packet, which results in a situation that multiple pieces of external data are received within one video frame time; for example, if a video packet corresponds to a time length of 40ms, the external data of the vehicle may change continuously within 40ms after the frame acquisition time stamp value, for example, a turn signal, a vehicle speed change signal, etc. are generated within 40ms, so that more than one external packet is matched with the video packet matched with the video frame when the video packet is associated and packed.

According to the technical scheme, all video data and all external data of a target vehicle within a preset time length are acquired in real time through an acquisition system, all acquired video data are filtered based on preset video filtering rules to obtain all target video data conforming to the preset filtering rules, all external data are classified and packed based on acquisition sources of the external data to obtain at least one external data packet, all target video data are input into a preset operation model to obtain operation time parameters, frame acquisition time stamp values and marking information matched with all target video data, the operation time parameters, frame acquisition time stamp values and marking information are packed with the matched target video data to obtain all video data packets, finally all video data packets and all external data packets are associated and packed according to the time length and frame acquisition time stamp values in all video data packets, so that data recharging systems can read data, the data correlation of the acquired data is guaranteed, and the acquisition of various types of data of vehicle-mounted equipment is realized.

S240, carrying out data classification on each external data packet according to the source mark value, and calling at least one data transmission module to respectively send each external data packet based on the classification result so as to recharge each external data packet to the target system.

The method for classifying the data of each external data packet according to the source mark value, and calling at least one data transmission module to respectively transmit each external data packet based on the classification result comprises the following steps: analyzing the source marking values to obtain the acquisition sources of the external data packets; calling a CAN data transmission module to transmit an external data packet with a collection source of a CAN interface; calling an I/O data transmission module to transmit an external data packet with an acquisition source of an I/O interface; calling a serial data transmission module to transmit an external data packet with a collection source being a serial data interface; and calling a network data transmission module to transmit the external data packet with the acquisition source of the network data interface.

Optionally, in this embodiment, the external storage module includes: TF external memory card or hard disk with storage function.

By the scheme of the embodiment, all video data and external data in a specific time period can be recharged; in the prior art, when the scene simulation of the vehicle is carried out, only one data type is usually recharged for simulation; for example, if the prior art wants to recharge video data when recharging the data, only the video data can be recharged but other types of data cannot be recharged, and when scene simulation is performed based on the video data, only the simulation of the vehicle in the video scene can be performed, but the composite simulation of the speed, gear, left and right steering of the vehicle, gps positioning and the like of the vehicle in the current video scene cannot be performed; by means of the scheme, when video data recharging is carried out, the recharging system can recharge external data matched with the video data to the target system, and when scene simulation of the vehicle is carried out on the basis, video simulation of the vehicle under the conditions of current speed, gear, left and right steering of the vehicle, gps positioning and the like can be carried out, and simulation verification effect of the vehicle environment is greatly improved.
