The decoder of end connection, the FPGA being connect with the output end of the decoder, the encoder being connect with the output end of the FPGA, with
And it is connected to the memory on the FPGA；The FPGA is also connect with the automobile prior-warning device, the output end of the encoder
It is connect with the display device.
The present invention also provides the realization sides of the above-mentioned unshielding safe early warning display system based on automobile original vehicle system
Method includes the following steps：
(1) its corresponding color is preset according to the Pixel-level of early warning display area, phase is preset according to different display contents
The fusion coefficients answered, and the corresponding mark of region setting shown to not needing early warning；
(2) environmental images during automobile use are acquired in real time by data acquisition device, and be transferred to decoder into
Row decoding；
(3) each frame data for the environmental images that FPGA obtains data acquisition device carry out fusion operation processing respectively,
It is encoded finally by encoder, forms an alarm image；
(4) new environmental images are transferred to display device and automobile prior-warning device respectively, carry out display and early warning；It passes simultaneously
It is defeated by memory and carries out data storage.
Preferably, the calculating logic of the R values of a pixel of environmental images is as follows in the step (3)：
I. a=0 when transparent；
R=Rx；
A=255 when ii. blocking completely；
R=Ry
Iii. when translucent display
R=Rx* (255-a)/255+Ry*a/255
Wherein, R indicates that the most basic inscape of the graphical pixel color of digitized video, Rx indicate the image of former vehicle system
The R values of pixel in data, Ry indicate that the R values of pixel in alarm image data, a indicate pixel in alarm image data
Identify the attribute of fusion.
Compared with prior art, the invention has the advantages that：
(1) present invention carries out data acquisition using the original data acquisition device of automobile, and utilizes original display device
It carries out image to show, carries out early warning using original prior-warning device, without individually increasing pre-alarm display device, also do not need
Two kinds of early warning contents of display do not change the original global design of automobile, it is only necessary to collecting without switching early warning display system
Data carry out Data Fusion, make early warning show content it is more accurate, you can be obviously improved the security performance of automobile, design
It is ingenious, it is easy to operate, there is apparent technological progress.
(2) present invention is provided with apparent mark to not display area, realizes unshielding formula and shows, has merged former vehicle wind
Lattice will not be impacted car owner using former vehicle system, to preferably ensure that effective operating of safety pre-warning system.
(3) present invention will not increase auto cost without additional configuration external equipment, huge with wide popularization and application
Potentiality.
Description of the drawings
Fig. 1 is the system block diagram of the present invention.
Fig. 2 is the flow diagram of the present invention.
Specific implementation mode
The invention will be further described with reference to the accompanying drawings and examples, and embodiments of the present invention include but not limited to
The following example.
Embodiment
As shown in Figure 1, unshielding safe early warning display system disclosed by the invention, with the original-pack alarm display system of automobile
Based on, by using data anastomosing algorithm, data-handling capacity is promoted, to promote the safe early warning performance of automobile.
Specifically, the original-pack alarm display system of automobile includes data acquisition device, automobile prior-warning device and display device.
On this basis, the decoder being connect with the data output end of the data acquisition device is newly increased, the output with the decoder
The FPGA of connection, the encoder being connect with the output end of the FPGA are held, and the memory being connected on the FPGA.In addition, described
FPGA is also connect with the automobile prior-warning device, and the output end of the encoder is connect with the display device.
Meanwhile it being also configured with corresponding implementation method, as shown in Fig. 2, specific as follows：
