In view of the technical problems set forth in the background art, the application provides a vehicle-mounted system safety warning method, device, equipment and medium, which can process and render data acquired by a sensor at a server side and improve the safety auxiliary function of a vehicle-mounted system.

Referring to fig. 1 of the specification, the method for warning safety of a vehicle-mounted system provided by the embodiment of the application comprises the following steps:

s1, constructing the intelligent monitoring module, the vehicle-mounted terminal and the server into a wireless communication network through a wireless communication protocol;

s2, acquiring basic information of a current vehicle in real time based on the intelligent monitoring module, and sending the basic information to the server, wherein the basic information comprises surrounding environment information and driving data of the current vehicle;

s3, generating a three-dimensional scene view at a server by using the acquired basic information of the current vehicle, and predicting a collision event between the vehicle and surrounding obstacles in the running process based on a preset safety warning distance;

and S4, issuing the three-dimensional scene view generated by the server to a vehicle-mounted terminal for display, and identifying surrounding obstacles predicted to have a collision event so as to execute corresponding safety measures.

In the embodiment of the application, the vehicle-mounted system safety warning method is applied to a vehicle-mounted system, but the vehicle-mounted system is different from a traditional vehicle-mounted terminal mainly composed of a host computer, a display screen and an operation keyboard. Specifically, the vehicle-mounted system to which the vehicle-mounted system safety warning method is applied in the application comprises an intelligent monitoring module and a server besides the vehicle-mounted terminal. In step S1, the intelligent monitoring module, the vehicle-mounted terminal and the server are configured to form a wireless communication network through a wireless communication protocol, so that data and/or instructions are transmitted among the intelligent monitoring module, the vehicle-mounted terminal and the server in real time through the configured wireless communication network, thereby laying a foundation for improving the safety auxiliary function of the vehicle-mounted system.

The intelligent monitoring module includes a vehicle-mounted GPS, a plurality of sensors installed on the vehicle, and a microprocessor, in an embodiment, referring to fig. 2 of the specification, the intelligent monitoring module acquires basic information of a current vehicle in real time, and sends the basic information to the server, including the following steps:

s201, acquiring running data of the vehicle based on a vehicle-mounted GPS; the driving data comprise the current position coordinates of the vehicle and the information of the road section;

s202, acquiring current surrounding environment information of a vehicle based on a plurality of sensors installed on the vehicle; the sensor adopts various types to acquire one or more peripheral environment information including physical form, light shadow color and speed;

s203, preprocessing the acquired surrounding environment information of the current vehicle based on the microprocessor, summarizing the acquired running data of the current vehicle, and sending the running data to the server.

In step S201-step S203, the vehicle-mounted GPS and a plurality of sensors mounted on the vehicle can communicate with the microprocessor through serial ports RS-232, RS-485, UART and I2C, SPI, CAN, and the microprocessor can communicate with a server wirelessly through a 4G/5G module. The acquiring of the current driving data of the vehicle through the vehicle-mounted GPS is a technical means well known to those skilled in the art, and will not be described herein in detail; in the application, the sensor comprises various types, such as radar, camera and laser radar, so as to improve the comprehensiveness and accuracy of information acquisition and lay a foundation for a subsequent server to process data and render images.

In the application, the number of the sensors is increased, and the mounting positions of the sensors are optimized, for example, cameras can be mounted on the front, the side and the rear of a vehicle, so that the omnibearing visual field coverage is improved; radar may be installed in front and rear of a vehicle to detect obstacles in front and rear. In addition, in an embodiment, besides installing cameras on the front side, the side and the rear of the vehicle, cameras or radars are additionally arranged at the center of each wheel hub of the vehicle, and a fish-eye view angle is adopted, so that the whole image of the bottom of the vehicle body can be spliced through the processing of a subsequent server on collected data, a chassis image and a ground image under the chassis are played, whether the vehicle body chassis has foreign matters or not is checked before the vehicle is started or in the running process, whether abnormal conditions such as liquid leakage and the like exist on the ground or not is checked, and corresponding warning is carried out.

In addition, the application can also realize correction among the sensors by arranging a plurality of sensors so as to ensure that the sensors can accurately capture the same object or environment information. And preferably, the fisheye cameras are embedded in the bearings of the four hubs of the vehicle, so that the cameras cannot rotate along with the hubs in the static and moving processes of the vehicle, the collected images cannot rotate, and the complexity of processing data by a subsequent server is reduced.

Furthermore, in order to improve the efficiency of processing data by the subsequent server, the microprocessor of the intelligent monitoring module is used for preprocessing the current surrounding environment information of the vehicle, such as filtering, denoising, correcting and the like, acquired by the sensor, and then transmitting the running data acquired by the vehicle-mounted GPS to the server.

In step S3, the server is preferably a cloud server, which is not limited by hardware resources and has extremely strong computing performance, and can meet the real-time requirement of the safety auxiliary function of the vehicle-mounted system. In the application, the cloud server processes the basic information of the vehicle, and the method mainly comprises two aspects, namely, generating a three-dimensional scene view from data acquired by a sensor, and predicting the traffic state based on the data acquired by the sensor.

In an embodiment, referring to fig. 3 of the specification, the generating a three-dimensional scene view at a server by using the obtained basic information of the current vehicle includes the following steps:

s301, carrying out three-dimensional modeling on surrounding environment information of the current vehicle based on running data of the current vehicle, and generating a plurality of three-dimensional pictures according to time sequence;

s302, rendering the plurality of three-dimensional pictures frame by frame according to set parameters and encoding the three-dimensional pictures into a video file in a set format to obtain the three-dimensional scene view.

When data acquired by a sensor are generated into a three-dimensional scene view, mainly fusing running data acquired by a GPS (global positioning system) with surrounding environment information acquired by the sensor, generating a plurality of three-dimensional pictures according to time sequence in a three-dimensional modeling mode, classifying objects in the surrounding environment in the generated three-dimensional pictures, such as animals, human beings, vehicles and buildings, filling each type of object through a pre-stored material library, realizing frame-by-frame rendering of the three-dimensional pictures, and being beneficial to visual identification of users; further, the rendered three-dimensional picture is also encoded into a video file in a set format. For example, the set format is an MP4 video file in H264 format. In other embodiments, the video formats may be set according to the host capabilities of the in-vehicle terminal, such as resolution (4K), frame rate (120 fps), video formats (rmvb, wmv), which is not limited or fixed by the present application.

Because the hardware resources required for rendering the three-dimensional picture are larger, and the performance of a host of a general vehicle-mounted terminal cannot meet the requirement of rendering the three-dimensional picture, the three-dimensional picture rendering and video coding functions are added to the cloud server, the frame pictures are written into MP4 files, and video standard definition is added to standardize parameters such as video frame rate, resolution and the like, so that the playing effect of the vehicle-mounted terminal is ensured.

When the cloud server predicts traffic state based on data acquired by the sensor, a first running track of the vehicle in a current period and a future period is mainly generated through running data acquired by the vehicle-mounted GPS, and a second running track of surrounding objects (such as animals, humans and vehicles) in the current period and the future period is generated by combining surrounding environment information acquired by the sensor, so that whether the first running track and the second running track are intersected or not is analyzed, or the distance between the first running track and the second running track at a certain time point is smaller than a set safety warning distance. If the first running track and the second running track are crossed, the collision of the vehicle and the surrounding objects is indicated, and if the distance between the first running track and the second running track is smaller than the set safety warning distance at a certain time point, the possibility of the vehicle rubbing the surrounding objects is indicated.

Further, a plurality of thresholds are set for the preset safety warning distance, so that the level of collision event generated between the vehicle and surrounding obstacles is judged based on the safety warning distances of different thresholds, and the object to be collided is identified through different alarm colors.

In step S4, a video file receiving unit is additionally arranged in the host of the vehicle-mounted terminal, and is used for receiving the three-dimensional scene view sent by the cloud server, and displaying the three-dimensional scene view in a display screen of the vehicle-mounted terminal, so as to prompt a driver to change the current driving strategy, such as speed reduction, whistling and the like.

Therefore, according to the vehicle-mounted system safety warning method provided by the application, the comprehensiveness of data acquisition is improved by optimizing the layout number and the positions of the sensors, and the cloud server is used for processing the data acquired by the sensors, so that the real-time performance of safety warning is improved; and add picture rendering and video coding function to the high in the clouds server, add video file receiving unit to vehicle-mounted terminal's host computer to show the three-dimensional scene view that the high in the clouds server handled in real time on the display screen, promote vehicle-mounted system safety auxiliary's performance, solve the problem that the safety auxiliary function precision is poor, the image quality is low because of vehicle-mounted host computer performance is not enough in prior art.
