Described analyzed by video-splicing technology drives prior-warning device, the early warning master to the auxiliary of road conditions before vehicle
The two-path video signal of input is assigned as two-way by machine, carries out processing analysis all the way, is judged as early warning；Another way carries out defeated
Out, continue to be transferred to Tachographs and be monitored and record a video；It is other do not need carry out early warning analysis cameras still according to
Generic way accesses Tachographs.
The working method by driving prior-warning device before from video-splicing technology analysis vehicle to the auxiliary of road conditions, when
After auxiliary drives prior-warning device by carrying out processing analysis to the vision signal of input, such as it is judged as alarm condition, then by pre-
Alert prompting device carries out buzzing and image early warning to driver, while alarm signal is exported by alarm output circuit and is remembered to traveling
The general purpose I/O for recording instrument is alarmed input port, and Tachographs detect after IO after alarm input, by when alarming image and video lead to
It crosses in wireless network transmissions to portion of state mark monitor supervision platform；Monitoring operation personnel pass through state/portion's target universal monitor platform realization pair
Vehicle carries out traveling record system monitoring and auxiliary drives early warning monitoring.
The working method by driving prior-warning device before from video-splicing technology analysis vehicle to the auxiliary of road conditions, it is auxiliary
Help pilot instrument host mainly by video-splicing algorithm, video decoding conversion circuit, MCU, alarm output circuit and general
Power supply, communication and storage circuit composition.
The working method by driving prior-warning device before from video-splicing technology analysis vehicle to the auxiliary of road conditions, depending on
Frequency splicing in forward video acquisition, using three 720p cameras be respectively placed in the front of vehicle to, right direction, left side side
To, obtain forward direction image, the image right, left-side images of driving, using video-splicing algorithm will drive a vehicle before to 180 degree range
Acquisition of the image without " gap ", thus to image within the scope of Chinese herbaceous peony 180 degree, lane, pedestrian, parallel vehicles, vehicle side object into
Row is screened and is obtained.
The working method by driving prior-warning device before from video-splicing technology analysis vehicle to the auxiliary of road conditions, depending on
Frequency obtains the i.mx6 main control chip using NXP company and the NPV6158 video decoding chip of nextchip company, passes through
NPV6158 decodes three road videos, and analog signal is switched to digital signal, is inputted digital signal by the method for time-sharing multiplex
In i.mx6, the splicing of video and the identification of object are carried out in i.mx6, calculates distance, generate auxiliary driving strategy.
The utility model has the advantages that
1. the present invention is capable of providing more reliable vehicle forward video sampling, assist driving caused by reducing because of the preceding blind spot to sampling
The phenomenon that system anticipation fault, using effect is good, and sampling is accurate.
The present invention solves the problems, such as left and right vehicle wheel two sides blind area, has bigger mention to the reliability of DAS (Driver Assistant System)
It rises.
