Detailed Description
The embodiment of the invention provides a method and a device for demonstrating an intelligent vehicle-mounted ADAS function and terminal equipment, which are used for solving the problem of unreal effect when the ADAS function is simulated and demonstrated.
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of a method for demonstrating an intelligent vehicle-mounted ADAS function according to the present invention includes:
101. the method comprises the steps that live videos of a vehicle provided with a specified vehicle-mounted product with an ADAS function when the vehicle runs in a real scene are collected and stored in advance, wherein the live videos comprise video data shot by an ADAS camera when the vehicle runs for detecting the front of the vehicle;
the execution main body in this embodiment may be a terminal device, such as a computer in a demonstration field, or may be a server, such as a cloud server in communication connection with the computer in the demonstration field, and so on. Preferably, the execution body is a terminal device.
It can be understood that, in order to obtain the live data of the vehicle, a specific ADAS-enabled vehicle-mounted product may be installed on the vehicle in advance, and then the driver drives the vehicle, and the terminal device captures the live video generated by the specific vehicle-mounted product during the driving of the vehicle. Wherein the live video comprises video data shot by the ADAS camera during driving when the front of the vehicle is detected. Since the video data are generated by actually driving the vehicle and are not obtained in a simulation mode, the video data can bring better experience to customers during demonstration.
The method comprises the following steps that a plurality of paths for acquiring a live video in a real scene exist, for example, a specified vehicle-mounted product can be installed on a company employee vehicle, and then the vehicle is normally driven or is driven in a special scene for obtaining when the employee normally drives; or, the appointed vehicle-mounted product can be installed on a company public vehicle, and a driver can drive the vehicle specially to obtain the appointed vehicle-mounted product at leisure time or obtain the appointed vehicle-mounted product by the driver during the period of delivering the client; and so on.
Further, as shown in fig. 2, the step 101 includes:
201. the method comprises the steps of collecting live videos of vehicles which are provided with specified vehicle-mounted products with ADAS functions and run in real scenes in advance;
202. and storing the live video by adopting the sub code stream and/or the main code stream.
Corresponding to the above steps 201 and 202, after the live video is collected, the live video is preferably stored in a sub-stream and/or main stream. The subcode stream mode is convenient for subsequently checking the algorithm superposition effect on the live video, and the live video has relatively poor quality but occupies less memory; the main code stream form reserves the original form of the live video and is high-definition, so that algorithm processing and video evidence storage are facilitated, and the relatively large occupied space is also large. The two forms of stored live video generally have an encryption effect (such as 264 format, etc.), non-dedicated software cannot normally play, but the stored live video can be opened for playing through the dedicated software, and can also be exported to be in other non-encryption formats (such as avi format, etc.) to facilitate operations of other requirements.
Preferably, after the sub-stream and/or the main stream is used for storing the live video, on one hand, the live video stored in the sub-stream can be used for viewing the actual execution effect of the algorithm, and on the other hand, the live video stored in the main stream can have 3 purposes: 1) the research and development part and the algorithm part are used as data processing materials; 2) the encrypted live video can be reserved for relevant demonstration and backup, the encrypted live video is the original form of the recorded video, and the inherent format and the converted video files in other formats have respective purposes, so that the encrypted live video has a greater reserved value; 3) the better non-encrypted video clip is intercepted and reserved for algorithm verification and effect display, live videos of different scenes and different conditions are classified, and a set of material library of the live videos of normal scenes and abnormal scenes (false alarm, missing report and other abnormal scenes) can be formed.
102. Reading a stored live video corresponding to the specified vehicle-mounted product when demonstrating the specified vehicle-mounted product;
it can be understood that when a specific vehicle-mounted product needs to be demonstrated to a customer, a live video corresponding to the specific vehicle-mounted product needs to be read, and since the live video is stored in the database, the live video can be found and acquired from the database through retrieval and the like.
103. Performing video decoding on the read live video;
104. playing the video decoded live video.
For the above steps 103 and 104, after reading the corresponding live video, the terminal device needs to perform video decoding on the read live video, and then play the live video after video decoding, so as to perform presentation of the live video.
Further, the demonstration of the designated vehicle-mounted product in the embodiment can be divided into the demonstration for the scene inside the vehicle and the demonstration for the scene outside the vehicle. The scene outside the vehicle mainly comprises forward vehicle collision, vehicle distance detection, lane departure, blind area monitoring, face recognition detection around the vehicle and the like corresponding to the ADAS camera, namely the video data; the scene in the vehicle mainly includes Driver behavior detection corresponding to a DSM (Driver State Monitoring, warning of collision with a pedestrian ahead) camera and a situation in the vehicle of sweeping to judge whether there is an excess person or not. Therefore, the live video further includes display data recorded when the DSM camera detects the behavior of the driver of the vehicle while driving, in this case, step 104 may specifically include: playing the video data in the video-decoded live video on a first display area of a designated display device, while playing the display data in the video-decoded live video on a second display area of the designated display device. Like this, the video data to the scene outside the car and the display data to the scene in the car of simultaneous display on same appointed display device can make the demonstration to appointed on-vehicle product more lifelike and comprehensive, bring the experience of being personally on the scene for the customer who watches.
Preferably, when the specified display equipment is demonstrated, the display data of the scene in the vehicle can be demonstrated in a real-time demonstration mode of field personnel, for example, the field personnel place vehicles of the same model at a demonstration site, the specified vehicle-mounted product is installed on the field personnel, and the field personnel can demonstrate the specified display equipment for customers.
Further, the embodiment can also record the running speed and the GPS positioning information of the vehicle running in a real scene when the live video is collected in advance; and then, when the video decoded live video is played, the running speed of the vehicle and the GPS positioning information corresponding to the picture of the live video are displayed at the same time. It can be understood that when the vehicle runs, the running speed and the GPS positioning information of the vehicle running in real time can be stored through the video black box data format, the data processed by the video black box data format needs to be played by special software on a computer, the software needs to have two functions, namely a module for receiving video black box data and a module for sending video black box data, and after the video black box data is matched with corresponding serial port wire rods for connection (a video format converter needs to be additionally arranged sometimes), the live video of the vehicle played by the software can have the real running speed and the GPS positioning information of the vehicle running at that time, the actual vehicle running condition can be vividly restored, the effect is good, and the convincing force is achieved.
In addition, when the live video is collected, the real-time running speed and GPS positioning information of the vehicle are not stored through a video black box data format, the embodiment can also be matched with a pulse generator to realize the running speed of the vehicle under the actual condition in the live video playing simulation, and the mode is only suitable for the demonstration scene that the vehicle speed is stable or the running speed is preset to trigger the alarm condition.
Preferably, when the step 104 is executed to play the decoded live video, the live video may be played in a full screen mode, and the mode is set to an automatic loop mode, so that the effect of performing uninterrupted play of the live video of the in-vehicle scene and the out-vehicle scene in the case that the demonstration venue is unattended can be achieved.
In this embodiment, the terminal device may be in communication connection with a host module on the vehicle, where the host module may specifically be a vehicle-mounted dvr (mobile Digital Video recorders) on the vehicle, which is a central module of the entire vehicle, can record a Video when the vehicle is running, and is provided with a GPS positioning module, a communication module, and the like. If the vehicle-mounted intelligent vehicle is connected with the terminal equipment through a serial port line and the like and is matched with the video black box data acquisition and sending software, the driving speed and GPS positioning information in the video black box data can be transmitted to the terminal equipment, the indoor restoration display of the real scene outside the vehicle can be realized, the code superposition effect capable of reflecting the real driving condition of the vehicle can be checked in real time after the algorithm processing, the vehicle-mounted intelligent; if the pulse device is connected with the designated vehicle-mounted product, the vehicle-mounted DVR can simulate the algorithm superposition effect at a fixed speed, and has the advantages that the simulation effect on short segments of scenes with higher requirements on the speed of the vehicle, such as front vehicle collision, can be realized, but the simulation effect is only good for other conditions, and the pulse speed can be manually adjusted according to different demonstration requirements to adapt to various functional requirements. The vehicle-mounted DVR is connected with the terminal device in a remote communication mode, and the bronze drum HDMI wire of the terminal device is connected with the display device.
Further, in the embodiment, when the live video is collected in advance, alarm information sent when the ADAS function detects an abnormal condition in the driving process of the vehicle can be collected together; and then, when the live video after video decoding is played, simultaneously outputting alarm information corresponding to the picture of the live video. It can be understood that, during the running process of the vehicle, if the ADAS function of the specified vehicle-mounted product detects an abnormal condition, such as too close distance, an alarm message will be sent out. The alarm information can be alarm pictures, characters, videos and the like. In order to truly restore the alarm function of the specified vehicle-mounted product, the terminal equipment can actively acquire the alarm information, and the specified vehicle-mounted product can also actively report the alarm information to the terminal equipment during driving. After the terminal equipment collects the alarm information, the terminal equipment can simultaneously output the alarm information corresponding to the picture of the live video when playing the live video after video decoding, and restore and demonstrate a real alarm scene; in addition, an alarm statistical report can be generated, corresponding pictures and small sections of videos can be provided according to alarm time or types, a complete set of evidence can be provided for corresponding events, and a whole evidence chain is formed. Furthermore, under the condition of no network connection, the platform server and the client can be installed on the vehicle system, a local area network can be constructed after the network connection, the alarm can be uploaded to the platform server in real time under the condition of no network, the platform server sends the alarm information to the terminal equipment, the system is very practical and convenient, the condition of no network connection is ensured, live video and alarm information are collected, the live video and alarm information are sent and uploaded to the terminal equipment after the network connection is finished, and the demonstration effect of a specified vehicle-mounted product is ensured.
It can be seen from the content that the demonstration method for the intelligent vehicle-mounted ADAS function provided by the embodiment has the following advantages:
(1) the method and the system can demonstrate both the ADAS function and the DSM function of the intelligent vehicle under a suitable indoor environment, and make up for the defect that the intelligent vehicle on the market has no perfect demonstration mode;
(2) the current situation that the real driving speed corresponding to an actual vehicle and data such as a GPS positioning system wants cannot be realized by improving the ADAS function demonstration video of the intelligent vehicle, and only speed supplement can be carried out by relying on pulses and the like is achieved, so that the real driving scene is restored, and the demonstration effect is improved;
(3) the demonstration mode is diversified, the demonstration of existing equipment is realized, someone is the demonstration again, and the demonstration of artificial mode also can demonstrate through the mode of computer screen projection, makes up the on-vehicle DSM function demonstration of intelligence and can not realize the demonstration mode that existing real-time artificial scene demonstration, the simulation demonstration that has the screen end to broadcast again combines together not enough.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
