The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1 and Figure 2, the utility model embodiment cannot intuitively obtain the problem of front vehicle specifying information for existing back mirror, a kind of rearview mirror for automobiles assembly is provided, described rearview mirror assembly is arranged on car body, described rearview mirror assembly comprises: radar 2, described radar 2 is installed on hull back, monitoring front vehicle 1; First 4, the camera 25 of making a video recording, described shooting first 4 is all installed on meter panel of motor vehicle with described camera 25, monitoring chaufeur eyeball 3; Back mirror 8, S. A. 7, described back mirror 8 is installed on car body by described S. A. 7; Angular transducer 6, described angular transducer 6 is installed on S. A. 7; Graphics processing unit 10, control unit 11, described graphics processing unit 10 is all installed on meter panel of motor vehicle with described control unit 11; Transparent demonstration film 12, described transparent demonstration film 12 fits on described back mirror 8.
Further, first 4, the described camera 25 of described radar 2, described shooting, described S. A. 7, described angular transducer 6 are all connected adaptive with described transparent demonstration film 12 with described control unit 11 with described graphics processing unit 10.
Wherein, described radar 2 is installed on hull back, for monitor front vehicle 1 angle and distance, and related data transmission is gone over; Described shooting first 4 is all installed on meter panel of motor vehicle with described camera 25, monitoring chaufeur eyeball 3, by the 2-D data transmission of obtaining in the past; Described angular transducer 6 is installed on S. A. 7, and by described S. A. 7, described back mirror 8 is installed on car body, the angle that described angular transducer 6 turns over for adding up back mirror 8, and transmit data.
Further, described transparent demonstration film 12 fits on described 8 back mirrors, and its size shape is identical with described back mirror 8; When system is not worked, chaufeur can see through transparent demonstration film 12 and see back visibibility by back mirror 8, during system works, chaufeur can see through transparent demonstration film 12 and see back visibibility by back mirror 8, the specifying information that also shows this vehicle on the position of the vehicle virtual image 9 at the rear that meanwhile, chaufeur can be seen.
The principle of work of the utility model embodiment is as follows:
Car body is set up to cartesian coordinate system, and radar 2, first 4, the camera 25 of making a video recording, S. A. 7, graphics processing unit 10, control unit 11 are installed on car body fixed position, thereby coordinate is fixed.
The 2-D data of the chaufeur eyeball 3 first 4 by making a video recording, camera 25 records, and establish equation of straight line of monobasics according to line one c, line two e, thus calculate the coordinate of chaufeur eyeball 3.
Line of position f by radar 2 with front vehicle 1, determines the coordinate of front vehicle 1, and records angle and the distance of front vehicle 1; According to actual situation, as line b and symmetry principle, determine the coordinate of the virtual image 9, or according to pilot's line of vision a(chaufeur eyeball 3 line with the virtual image 9) establish the coordinate that equation is determined the virtual image 9.
Regulation back mirror 8 is when a certain position, and the value of angular transducer 6 is zero, and while driving back mirror 8 rotation according to S. A. 7, angular transducer 6 records the corresponding anglec of rotation, establishes the real-time equation of back mirror 8 and transparent demonstration film 12.
The calculating of the data by graphics processing unit 10 and 11 pairs of collections of control unit, accurately draw every running data of front vehicle 1, and be presented at the intersection point d of the real-time equation of pilot's line of vision a and back mirror 8, be the position of the picture of the front vehicle 1 seen of chaufeur in back mirror 8.
On the transparent demonstration film 12 of this position, chaufeur can intuitively obtain the information of front vehicle 1, as distance, relative velocity, the information such as how long can be caught up with.
In such scheme, the front vehicle specifying information that chaufeur is seen by back mirror, as the speed of front vehicle, distance, how long can, by data such as this car catch up with, make chaufeur grasp accurately front vehicle information, be beneficial to chaufeur and judge the strategy of driving, improve the safety factor of driving.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
