Problems solved by technology
At present, there are many types of driving recorders on the market, and the prices vary widely. However, most of them are not equipped with the original car and need to be purchased separately. It is uneven, and most of them can only record simple information such as video images and sounds, and record the time of the incident. When providing evidence when a traffic accident occurs, the evidence is relatively single, and it is impossible to fully understand the state of the vehicle at the time of the incident and restore the most authentic scene of the incident

Embodiment Construction
[0031] See figure 1 , figure 2 , A method of multi-core superimposed vehicle signal state icon, including the following steps:
[0032] Step 1: The first processor runs the Linux system, updates the vehicle signal icon data through the first processor, and the vehicle signal icon data includes recording state, datetime, position, lateral and longitudinal acceleration, vehicle speed, gear position, steering lamp. data;
[0033] Step 2: Updated icon data places in the shared cache area of the internal memory;
[0034] Step 3: The second processor runs the SYS / BIOS system, and the updated icon data is obtained from the shared cache through a nuclear communication;
[0035] Step 4: The second processor superimposes the vehicle signal icon data to the camera input image data, outputs it onto the display.
[0036] Specifically, step 4 includes the following steps:
[0037] Step A: First obtain the original image data input by the four-way camera, obtain the spliced image after the...

The present invention provides a multi-core-based method, device and medium for superimposing vehicle signal state icons, which can be superimposed on image data to superimpose vehicle signal state icons, occupying less resources, including the following steps: Step 1: making and Update the vehicle signal icon data in real time; Step 2: The updated icon data is put into the shared buffer area of the internal memory; Step 3: The second processor obtains the updated icon data from the shared buffer area through inter-core communication; Step 4: The first The second processor superimposes the vehicle signal icon data and the camera input image data, and outputs them to the display.
Description
Technical field [0001] The present invention relates to the technical field of in-vehicle system, and more particularly to a method, apparatus, medium of a multi-core overlay vehicle signal state icon. Background technique [0002] Traffic security issues have become worldwide. According to reports, the world has about 500,000 in the world's death, so the safety of automobile safety on human life and property is self-evident. With the development of the expressway and the improvement of automobile performance, the speed of the car is also accelerated, and the number of casualties and property damage caused by the number of vehicles and increasing transportation is increasing, and has become a social problem that cannot be ignored. Car driving safety is more important. The traditional passive safety is far from avoiding traffic accidents, so the concept of active security is slowly formed. [0003] The driving recorder is a instrument that records related information such as image...
