[0049] Embodiments of the present application are described in detail below with reference to the accompanying drawings, in which the same or similar components have the same or similar reference numbers throughout the drawings and a detailed description of the same or similar components is not repeated. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.

[0050] A driving video management method and system, a domain controller, a computing device and a computer readable storage medium according to embodiments of the present application are described below with reference to the accompanying drawings.

[0051] Figure 1 is a flowchart of a driving video management method according to an embodiment of the present application, the method applied to a domain controller, which can include the following steps.

[0052] Step 101: receiving a video stream collected by a camera connected to the domain controller.

[0053] In a specific implementation, the domain controller establishes a connection with a camera configured in a vehicle, supplies power to the camera, and transmits the video stream collected by the camera in real time to the domain controller.

[0054] As an example, the domain controller can be a cockpit domain controller or an in-vehicle entertainment information controller, which is connected to the camera by coaxial LVDS (Low Voltage Differential Signaling), and the camera transmits the video stream to the domain controller through the LVDS interface. Moreover, the camera can be a front-view / AR (Augmented Reality) camera configured on the front windshield of the vehicle, and the resolution of the video stream collected by the camera is 1920x1080@30fps.

[0055] In some embodiments, although the domain controller integrates the driving record software, the driving record software needs to be started in the case that the camera is determined to be in normal state. Therefore, after the domain controller establishes a connection with the camera, the domain controller can detect the state of the camera in real time, and if the camera is in normal state, the domain controller receives the video stream collected by the camera in real time, and if the camera is not in normal state, the domain controller displays a black screen on the display screen of the domain controller and displays a prompt information to remind the user to check the camera. For example, the prompt information can be "Camera is abnormal, please check the camera".

[0056] As an example, the state of the camera can be determined by detecting whether the GMSL (Gigabit Multimedia Serial Links) signal of the camera is normal, and the driving record software of the domain controller can be started to receive the video stream transmitted by the camera in the case that the state of the camera is determined to be normal.

[0057] Step 102: In the case that the domain controller is connected with the external storage device and the state of the external storage device is normal, the driving video is obtained by parsing the video stream.

[0058] In the embodiments of the present application, in order to save the storage space of the domain controller, the external storage device can be connected to store the driving video, therefore, the domain controller also needs to determine whether the external storage device is connected and the state of the external storage device, and the received video stream is parsed in the case that the external storage device is connected and the state of the external storage device is normal.

[0059] As an example, the external storage device can be a U disk (USB flash disk) or a TF card (Trans-flash Card) or any storage device that can be connected with the domain controller and has a storage function. The normal state of the external storage device includes that the remaining capacity of the external storage device is sufficient, the partition is reasonable, and no irrelevant files are stored.

[0060] In specific implementation, the domain controller can first detect whether the external storage device is connected, if not, a pop-up window is displayed to remind the user to insert the external storage device, and the functions such as video recording and shooting are stopped; if the external storage device is connected, the domain controller detects whether the external storage device can be normally used, if not, a pop-up window is displayed to remind that the external storage device is damaged, and the functions such as video recording and shooting are stopped; if the external storage device can be normally used, the domain controller detects the state of the external storage device. Specifically, the domain controller detects whether the remaining capacity of the external storage device is sufficient, whether the storage space is partitioned, whether the partition is reasonable, and whether irrelevant files are stored, and if all the conditions are met, the domain controller determines that the state of the external storage device is normal, the domain controller can receive the video stream collected by the camera in real time, and the driving video is obtained by parsing the video stream.

[0061] As an example, the domain controller can detect the remaining capacity of the external storage device, and compare the remaining capacity with a preset capacity threshold. If the remaining capacity is greater than the preset capacity threshold, it is determined that the remaining capacity of the external storage device is sufficient. In addition, it can be detected whether the storage space of the external storage device has been divided into a preset number of partitions, i.e. whether the external storage device includes a preset number of folders. If yes, it is detected according to the naming rule whether there are irrelevant files in each partition of the external storage device. If not, it can be determined that the state of the external storage device is normal.

[0062] Exemplarily, the irrelevant files can be files irrelevant to vehicle driving or videos not captured by a camera. The preset capacity threshold and the preset number can be set according to actual needs, which are not limited in the embodiment. For example, the preset capacity threshold can be 7.6G, and the preset number can be 3.

[0063] Further, if it is detected that the remaining capacity of the external storage device is insufficient, information for replacing the external storage device is generated and displayed. If it is detected that the external storage device is not partitioned, the storage space of the external storage device is partitioned. If it is detected that the partition of the external storage device is unreasonable, the external storage device is formatted and the storage space is repartitioned. If it is detected that the partition of the external storage device is reasonable and there are irrelevant files in the partition, the irrelevant files are deleted.

[0064] That is, if it is detected that the remaining capacity is less than or equal to the preset capacity threshold, it is determined that the remaining capacity of the external storage device is insufficient. Information for replacing the external storage device can be generated and displayed so that the user replaces the external storage device. If it is detected that the remaining capacity of the external storage device is sufficient but the storage space is a whole and has not been divided into multiple partitions, the storage space of the external storage device is divided into a preset number of partitions. If it is detected that the external storage device has been partitioned but the number of partitions is not a preset number, the external storage device is formatted and the storage space is divided into a preset number of partitions. If it is detected that the number of partitions of the external storage device is a preset number but there are irrelevant files in the partition, such as entertainment videos recorded by the user, the irrelevant files are deleted.

[0065] Exemplarily, taking the external storage device as a U disk, the preset capacity threshold as 7.6G, and the preset number as 3 as an example, when the user inserts the U disk into the USB interface of the domain controller, the domain controller starts to detect the state of the U disk, which specifically includes:

[0066] If it is detected that the remaining capacity of the U disk is insufficient, i.e. the remaining capacity of the U disk is less than 7.6G, information for replacing the U disk is generated as a pop-up window to remind the user to replace a U disk with a large capacity.

[0067] If it is detected that the U disk is empty (i.e. the remaining capacity of the U disk is sufficient) and the U disk is not partitioned, the storage space of the U disk is partitioned to automatically generate three folders (automatic video storage area / emergency video storage area), and the received video stream is parsed without prompting formatting;

[0068] If it is detected that the U disk has other folders in addition to the three partitioned folders (automatic video storage area / emergency video storage area), a pop-up window is prompted to format, and if the user selects formatting, the external storage device is formatted and then partitioned, and if the user does not select formatting, the video stream is not received;

[0069] If it is detected that the U disk has three folders (automatic video storage area / emergency video storage area), but there are irrelevant files (i.e. files not recorded by the driving record software) such as entertainment videos stored by the user in the three folders according to the naming rules, a pop-up window is prompted, such as "There are irrelevant files in the U disk, please delete", and if the user clicks OK, the irrelevant files are deleted, and if the user clicks Cancel, the operation of receiving the video stream is not performed;

[0070] If it is detected that the U disk is damaged, a pop-up window is prompted to the user that "The U disk is damaged and cannot be used normally", and at this time the automatic video, emergency video and user shooting are not available; if the U disk is not detected, a pop-up window is prompted to the user to "insert the U disk", and at this time the automatic video, emergency video and user shooting are not available.

[0071] In the embodiment of the application, the domain controller enables the driving record software when it is determined that the state of the camera and the external storage device are both normal, receives the video stream collected by the camera, and parses the video stream to obtain the driving video, so as to ensure the normal management of the driving video.

[0072] According to one embodiment of the application, after receiving the video stream collected by the camera, the video stream needs to be parsed into a driving video that can be managed by the domain controller. The specific implementation of parsing the video stream to obtain the driving video can include: dividing the video stream into multiple video segments according to the recording duration, and parsing each video segment, and in the parsing process, if the domain controller is disconnected from the external storage device, the current video segment that is not completed is continued to be parsed until the domain controller is reconnected with the external storage device, and the contents parsed before and after the disconnection are combined to obtain the driving video corresponding to the current video segment.

[0073] The recording duration can be pre-set according to actual needs and adjusted according to actual conditions. For example, the recording duration can be 3 minutes.

[0074] In a specific implementation, the video stream is parsed in segments. The video stream can be divided into multiple video segments according to the recording duration, and each video segment is parsed to obtain and store the driving video of each video segment. In addition, since the embodiment of the application needs to connect an external storage device to the domain controller to realize normal reception and parsing of the video stream, if the connection between the domain controller and the external storage device is disconnected under the condition that the driving record software is working normally, the current video segment being parsed can continue to be parsed. After the external storage device is connected to the domain controller again, the driving videos parsed before and after the disconnection of the current video segment are merged as the driving video corresponding to the current video segment, and multiple driving videos can be obtained.

[0075] For example, assuming that the recording duration is set to 3 minutes, the U disk is pulled out at 2 minutes and 40 seconds, and the remaining 20 seconds are parsed and cached in the User Data of the UFS. After the U disk is reinserted, the domain controller generates a 3-minute driving video by processing the two parts of the video.

[0076] Further, after receiving the video stream collected by the camera, the method further includes: in a case where an emergency event trigger signal is received, obtaining an emergency video stream of a preset time length collected before and after a time point corresponding to the emergency event trigger signal from the video stream. Correspondingly, the specific implementation of parsing the video stream to obtain the driving video can include: parsing the emergency video stream to obtain an emergency video.

[0077] The preset time length is set according to actual needs, and since the emergency event usually occurs in an instant, the preset time length can be less than the recording duration. For example, the preset time length can be 30 seconds. The emergency video folder can be a partition of the external storage device.

[0078] For example, the emergency event trigger signal can be an airbag deployment signal or an AEB braking signal.

[0079] In a specific implementation, the camera can collect the video around the vehicle in real time and transmit the video to the domain controller. The domain controller parses the received video stream to obtain the driving video in a case where the driving record software integrated in the domain controller is started. That is, the management of the driving video by the domain controller needs to start the driving record software first. However, in the case of an emergency event, if the driving record software cannot be started in time, but the video related to the event needs to be collected, in a case where the domain controller receives an emergency event trigger signal through the CAN, a video stream of half of the preset time length collected before the trigger time point and a video stream of half of the preset time length collected after the trigger time point are obtained from the video stream, the two are merged to obtain an emergency video stream of the preset time length, and the emergency video stream is parsed to obtain an emergency video.

[0080] It should be noted that the implementation process of parsing the emergency video stream to obtain the emergency video is the same as the implementation process of parsing the video stream to obtain the driving video, and the related description of the above embodiment can be referred to, and the embodiment will not be described here.

[0081] In addition, if the emergency event trigger signal is received again or multiple times in the process of obtaining the emergency video stream, the trigger time point is superimposed on the emergency video stream collected in the half of the preset time period after the trigger time point, and the emergency video obtained by parsing the emergency video stream.

[0082] In the embodiment of the application, the domain controller opens the driving record software when it is determined that the states of the camera and the external storage device are both normal, and receives the driving video obtained by parsing the video stream collected by the camera. In addition, when the connection with the external storage device is disconnected during the normal operation of the driving record software, the currently parsed video stream can be temporarily stored in the storage space of the domain controller until the domain controller is reconnected with the external storage device, and the driving video obtained by parsing before and after the disconnection is combined to obtain the driving video of the currently parsed video stream. In addition, in the case of an emergency event, the domain controller can obtain the emergency video as long as it receives the emergency event trigger signal, without waiting for the driving record software to start, so as to ensure the normal collection of the emergency video.

[0083] Step 103: storing the driving video to the external storage device.

[0084] In the specific implementation, after the driving video is parsed, the driving video can be stored in the partition of the external storage device, and the real-time video and the emergency video can be stored in different partitions, so as to facilitate management and searching.

[0085] Further, during the driving of the vehicle, the domain controller can collect vehicle state data in real time, which can represent the state of the vehicle at each time point, and can specifically include audio data, time, airbag alarm information, autonomous emergency braking system (AEB, Autonomous Emergency Braking) trigger information, left and right turn signals, hazard warning light state information, etc. In addition, the vehicle state data can be added to the driving video, so that the obtained driving video not only has images but also vehicle conditions at the same time point, so as to facilitate the analysis of the driving condition of the vehicle based on the same, and the vehicle state data can be used as a reference to analyze the cause and responsibility of the danger when the danger occurs.

[0086] As an example, the real-time collected driving video (real-time video) and the driving video collected in an emergency (emergency video) can be respectively stored in different partitions of the external storage device, and the real-time video and the emergency video can also be named according to different naming rules. For example, the real-time video can be named as YYYYMMDD_hhmmss.mp4, and the emergency video can be named as YYYYMMDD_hhmmss_XXXX.mp4, where YYYYMMDD represents the year, month and day, hhmmss represents the hour, minute and second, and XXXX represents an index value, which ranges from 0001 to 9999. It should be noted that the storage mode of the driving video is a first-in, first-out circular coverage mode, and the later the time is, the more forward the display is.

[0087] Step 104: In response to the triggering operation of the domain controller integrated driving record software, the driving video stored in the external storage device is managed.

[0088] In a specific implementation, the management of the driving video can include playing, editing, analyzing and the like, all of which are for the user to determine what happened in the driving process of the vehicle according to the driving video.

[0089] According to an embodiment of the present application, in response to the triggering operation of the domain controller integrated driving record software, the specific implementation of managing the driving video stored in the external storage device can include: displaying a driving record interface after the driving record software is started; and displaying the driving video in real time on the driving record interface when the driving speed of the vehicle is not greater than a speed threshold.

[0090] The speed threshold can be pre-set according to actual needs, or can be obtained according to experiments, and the present embodiment does not limit this. For example, the speed threshold can be 15 kilometers / hour.

[0091] In a specific implementation, the domain controller can include a display screen, and the driving record interface can be displayed on the display screen during normal operation of the driving record software, which can be used to display the driving video. If the current driving speed of the vehicle is not fast, the real-time collected driving video can be displayed on the driving record interface; if the current driving speed of the vehicle is too fast (greater than the speed threshold), the driving video is not displayed on the display screen for safety considerations, and to avoid the user thinking that the driving record software is malfunctioning, a prompt information "for your safe driving, the driving video cannot be viewed at present" can be displayed on the driving record interface.

[0092] Figure 2 is a functional schematic diagram of a driving record software according to an embodiment of the present application. Referring to Figure 2The driving record software includes a file management function, a video display function, a setting function, and a quit function. The file management function includes real-time recording and emergency recording. In the list of real-time recording or emergency recording, each driving video can be played / paused, the previous / next one can be selected, and single or multiple selection deletion can be performed. The video display function can support real-time display of the driving video collected by the camera and display of the time point. The setting function supports setting of driving automatic recording start or stop, setting of recording duration, display of remaining capacity, selection of one-key cleaning, and selection of whether to restore the default setting.

[0093] According to one embodiment of the application, the driving record interface further includes a file management control and a setting control. The method further includes: displaying a file management interface in response to a triggering operation on the file management control, wherein the file management interface includes a plurality of driving videos; playing or editing a driving video in response to a playing or editing operation on any driving video; and displaying a setting interface in response to a triggering operation on the setting control, wherein the setting interface includes a plurality of setting options, and modifying a parameter of a setting option in response to a modification operation on any setting option.

[0094] Referring to Figure 3 , Figure 3 is a schematic diagram of a driving record interface according to an embodiment of the application. The driving record interface includes a quit button, a file management control, a driving video display area, a recording state display control, and a setting control. Clicking the quit button can exit the driving record software. Clicking the file management control can enter a file management page. Clicking the setting control can enter a setting interface to set automatic recording, storage space, and restoration of the default setting. The driving video display area does not display video content when no external storage device is detected, and can prompt insertion of an external storage device (a U disk or a TF card). When the vehicle speed is greater than or equal to a speed threshold, the video stream is not displayed, and the following is displayed: for your safe driving, the current recording content cannot be viewed. The recording state display control displays the current video acquisition state. When the external storage device is inserted and in a normal state, the display control displays recording in progress. When the external storage device is not inserted or is not in a normal state, the display control displays not enabled. In addition, a picture can be captured during video acquisition, and the resolution of the captured picture is consistent with that of the video. The picture storage adopts a cyclic coverage logic. When the picture folder is full, the latest captured picture will cover the earliest captured picture.

[0095] In a specific implementation, if the file management control is clicked, the display screen of the domain controller displays a file management interface, which includes a real-time video folder and an emergency video folder. The real-time video folder stores the driving video collected by the camera in real time, and the emergency video folder stores the driving video collected by the camera when an emergency occurs. If the user selects any folder and clicks any driving video in the folder, the driving video can be played, and during the playing process, the driving video can be played automatically in a loop, the video playing can be switched forward and backward, the currently playing driving video can be played / paused, and the video can be played by dragging the scroll bar. Alternatively, the user can long press a certain driving video, and then can select to delete the driving video or move the position of the driving video. Alternatively, the user can click the edit control, and then can select multiple videos or pictures for deleting, renaming, marking, moving, and the like.

[0096] Exemplarily, Figure 4 is a schematic diagram of a file management interface according to an embodiment of the application. The file management interface includes a real-time video control, an emergency video control, an edit control, and a plurality of driving videos. When the file management interface is clicked, the real-time video control is selected by default, a plurality of real-time collected driving videos are displayed, if any driving video is short pressed, the driving video can be played automatically, and a time watermark can be displayed on the driving video. If any driving video is long pressed, a delete control is popped up, and if the delete control is clicked, whether to delete the currently selected video is confirmed again. After the video is deleted, it cannot be restored. If Yes is clicked, the driving video is deleted. After the edit control is clicked, the edit control becomes a cancel button, a delete control is popped up, and multiple videos / pictures can be selected for deleting. It is required to display how many items are selected. After the delete control is clicked, whether to delete the selected items is confirmed again. If Yes, the selected videos / pictures are deleted.
