In figure: 1- camera, 2- radar, 3- signal-data processing unit, 4-CAN interface module, 5- connect panel type display.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
A kind of composition block diagram of ADAS display device of the utility model embodiment is as shown in Figure 1, described device includes: installation
For the video signal of acquisition vehicle front road and barrier in real time between shield glass and rearview mirror
Camera 1, be mounted on immediately ahead of automobile head for detect front obstacle and measure distance of the barrier with respect to automobile and
Immediately ahead of opposite automobile to azimuth deviation radar 2, the signal-data processing unit 3 being electrically connected with camera 1 and radar 2,
Signal-data processing unit 3 is used for by carrying out the song that image procossing calculates left and right sides lane line to the video signal
The distance of rate and opposite automobile, the position data combination video signal of the barrier detected according to radar 2 determine obstacle
The classification of object；Described device further includes the company's panel type display 5 communicated by CAN interface module 4 with signal-data processing unit 3,
For showing left and right sides lane according to the distance of the curvature measured in real time and opposite automobile with grid displaing coordinate line
The distance and bearing deviation of line, selection and the corresponding icon of barrier classification according to barrier with respect to automobile shows barrier.
In the present embodiment, described device is mainly by camera 1, radar 2, signal-data processing unit 3, CAN interface mould
Block 4 and the even composition of panel type display 5.Camera 1 is mounted between shield glass and rearview mirror, is used for captured in real-time automobile
The video image of road ahead and barrier, and video signal is sent into signal-data processing unit 3.Signal-data processing
Unit 3 carries out image procossing to video signal, obtains vehicle right and left two sides lane line (generally two lanes in this lane
Line) track, and calculate left and right sides lane curvature of a curve and automobile with two lane lines at a distance from (two distances and equal to vehicle
Road width).Radar 2 is mounted on (central location of headstock foremost) immediately ahead of automobile head, when work the transmitter of radar 2 to
Front electromagnetic signals, electromagnetic wave signal are reflected back after being irradiated to the barrier in front, and the receiver of radar 2 receives
The electromagnetic wave signal i.e. echo-signal of barrier is reflected, by being handled to obtain barrier with respect to automobile to echo-signal
