All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 schematically illustrates a flow chart of a virtual rearview mirror adjustment method provided by an embodiment of the invention, and the method can be applied to a driving model system at least.
As shown in fig. 1, the method mainly comprises the following steps:
103, determining the coordinates of a first rearview mirror viewpoint matched with a driver according to the information of the driver, and sending the coordinates of the first rearview mirror viewpoint to Vega Prime; so that the Vega Prime adjusts the position coordinates of the rearview mirror viewpoint according to the coordinates of the first rearview mirror viewpoint.
The virtual rearview mirror adjusting method provided by the embodiment of the invention is applied to a driving model system, and the automobile driving model system is a modern device for simulating the driving operation and the dynamic characteristic of a vehicle and providing the functions of driving training and driver characteristic analysis. According to the method provided by the embodiment of the invention, the rearview mirror imaging system applied by the method is used for researching key technologies in four aspects of an automobile dynamics simulation technology, a Visual scene generation technology, a driving training system and serial port communication, and establishing the structure of the rearview mirror imaging system by establishing software and hardware connection through serial port communication by using a Multigen Creator real-time three-dimensional modeling tool, a Vega Prime Visual scene simulation development platform and a Microsoft Visual Studio development environment in combination with a sensor technology.
Before the method is introduced, the construction of a driving simulator scene, a vehicle model and a rearview mirror model is introduced: the driving simulator scene is a virtual environment which is built based on a virtual reality scene technology and combined with Multigen Creator three-dimensional scene modeling and a Vega Prime scene simulation development platform. In order to truly explain the implementation method of the method, three-dimensional virtual scenes of different road sections are specially designed and established, the scenes can integrate expressways, mountain road sections and city road sections, set seasons are used as design backgrounds, and basic design parameters such as road width, super-high height, curvature and the like in the scenes meet related national regulations. For example, the total length of the scene road is about 20km, the different road sections are communicated with each other in pairs, a transition route and a guideboard prompt are arranged, and the scene also comprises elements such as a training field model, sound, animation and the like.
The vehicle model takes a popular Jetta vehicle model in reality as a prototype, and a three-dimensional virtual vehicle model is built by combining a Multigen Creator and a Vega Prime visual simulation development platform. And determining the position of the in-vehicle viewpoint according to the human eye percentile of the human engineering to obtain the in-vehicle viewpoint. The interior view point comprises a left rearview mirror, a right rearview mirror and an interior rearview mirror.
In step 101, the process of imaging the rear view mirror is a reflection process of light. The rear-view mirror viewpoint can be determined by the reflection law of light according to the main viewpoint and the rear-view mirror position.
Fig. 2 is a schematic view of a viewpoint mirror image of a rearview mirror provided in an embodiment of the present invention, and as shown in fig. 2, after an incident light ray I is triggered from a light source a and reaches the surface of the rearview mirror, a specular reflection occurs, so that the reflected light ray enters a main viewpoint C and causes a virtual image a' to be formed. Assuming that the surface of the rearview mirror is smooth and flat and has no any concave-convex, according to the law of reflection, I and R are symmetrical with respect to the normal vector N, and the diagram shown in fig. 2 is a mirror image effect diagram of the viewpoint of the rearview mirror.
In the embodiment of the invention, the rearview mirror visual scene realizes scene rendering and visual scene driving through the acf file made by Vega Prime. After the viewpoint of the rearview mirror is determined, the field of view of the rearview mirror can be further determined, specifically, the field of view angle and the field of view depth are set according to the imaging principle of the viewpoint of the rearview mirror, and the field of view of the rearview mirror is determined according to the field of view angle and the field of view depth. In practical applications, the viewpoint parameters of the rearview mirror can be set in the Transform of Vega Prime by the functions set Transform and set Rotate. Further, the rearview mirror viewpoint is set with a relative position parameter X, Y, Z, and the rearview mirror view range is set with relative rotation parameters Heading, Pitch, Roll.
After the viewpoint of the rear view mirror and the field of view of the rear view mirror are determined, the coordinate information of the rear view mirror may be further determined in step 102.
In the embodiment of the invention, a vehicle coordinate system of the driving simulator needs to be defined firstly, specifically, the position of the seat at the forefront of the travel is taken as a set origin R of the seat, and then an X axis, a Y axis and a Z axis are determined in sequence; wherein, X axle is on a parallel with ground and points to the vehicle place ahead, and Y axle points to driver's left side, and Z axle is vertical upwards.
Further, the eyepoint position information in this coordinate system, i.e., (x, y, z), is obtained by a visual field analysis method in ramis. It should be noted that RAMSIS (computer aided human body numerical system for occupant simulation) is a CAD tool specifically for automotive ergonomic design.
In the embodiment of the present invention, the viewpoint of the rearview mirror is a virtual viewpoint position of the eyepoint after mirroring the rearview mirror, and therefore, if the central coordinate information of the viewpoint of the rearview mirror is assumed to be (a, b, c), the position coordinate of the viewpoint of the rearview mirror can be determined, that is: x-2 a-X, Y-Y, Z-2 c-Z.
In practical application, because the fixed viewpoint of the rearview mirror can not be well adapted to drivers with different statures, in the embodiment of the invention, different eyepoints can be established according to the sex and the height of the driver, so that the driving adaptability and the comfort can be effectively improved. Specifically, through a large amount of human body size data in the RAMIS database, three-dimensional human body models of different figures are constrained according to the ergonomic principle, and the RAMIS visual field analysis method can automatically calculate the eyepoint position of the current human body model.
In the embodiment of the present invention, all men and women are classified into 10 groups according to the height and sex information of the driver, 10 different eye positions are obtained according to the classification, and the 10 eye position information is stored in the ramis.
In ramis, men and women are classified into 5 categories by height, in order:
A. very tail: 87 percent and above;
B. tall: 80-87 percentile;
C. medium: 20-80 percentile;
D. short: 13-20 percentile;
E. very short: 13 percentile or less.
In practical applications, the height percentile is a position indicator, for example, 50 percentile women correspond to a height of 1570 mm. Thus, all men and women are divided into 10 categories, a human body model is established by using the average value of each interval, and 10 human body models are respectively constrained, so that 10 eye positions can be obtained.
In step 103, the three-dimensional model of the driving simulator is input into the RAMSIS, and the RAMSIS determines and constrains the human body model according to the three-dimensional model of the driving simulator to obtain the human body sitting posture matched with the human body model and the eyepoint position matched with the human body sitting posture.
Further, when a driver enters the driving model system, the height and gender information of the driver needs to be input first, the RAMSIS determines a first eye position matched with the driver according to the height and gender information of the driver, it needs to be noted that the first eye position is one of 10 eye positions stored in the RAMSIS, and for the purpose of distinguishing and describing, one of the eye positions matched with the driver is called as the first eye position.
Further, according to the method for determining the coordinate information of the rearview mirror provided in step 102, the first eye point position and the center coordinate of the viewpoint of the rearview mirror are input into the coordinate formula of the viewpoint of the rearview mirror, so that the coordinate of the viewpoint of the first rearview mirror matched with the driver can be obtained. Here, the first rearview mirror viewpoint is one of the rearview mirror viewpoints, and for the sake of distinction, the one rearview mirror viewpoint matching the driver is referred to as the first rearview mirror viewpoint.
Further, after the RAMSIS determines the coordinates of the first rearview mirror viewpoint matched with the driver, the coordinates of the first rearview mirror viewpoint are sent to the Vega Prime; and calling an API (application programming interface) of Vega Prime to adjust the position coordinates of the viewpoint of the rearview mirror.
According to the method provided by the embodiment of the invention, different points of eyes may be confirmed by ramiss for different drivers due to different information input by different drivers, and further, the different points of eyes correspond to different viewpoint center coordinates of the rearview mirrors, and according to the viewpoint center coordinates of the rearview mirrors, the coordinates of the viewpoint of the rearview mirrors can be determined by the coordinate formula X of the viewpoint of the rearview mirrors being 2a-X, Y being Y, and Z being Z.
In summary, in the embodiment of the present invention, the driving seat is used as the origin and the center coordinate of the viewpoint of the rearview mirror, the coordinate of the viewpoint of the rearview mirror is determined, that is, the corresponding relationship between the coordinate of the viewpoint of the rearview mirror and the driving seat is established, and further, the position of the eyepoint matched with the driver and the coordinate of the viewpoint of the first rearview mirror are determined according to the driver information, so that the automatic adjustment of the rearview mirror can be completed according to the coordinate of the viewpoint of the first rearview mirror, and a method for automatically adjusting the rearview mirror according to the existence of different eyepoints of different drivers is formed. The problem of current virtual rear-view mirror have unable regulation and not high in the adaptability of rear view under different driving scenes is solved.
In order to more clearly describe the adjustment method of the virtual rearview mirror provided by the embodiment of the present invention, the following description describes that the eyepoint position is automatically generated by the ramis visual field analysis method, taking the left eye as an example, and part of the data is shown in table 1.

| Sex | Height of a person | Eye point coordinates |
| Woman | Very tall | (-125，34，719) |
| Woman | Medium | (-79，30，587) |
| Woman | Very short | (-38，480，27) |

The method comprises the steps of establishing a rearview mirror adjusting model, wherein the rearview mirror adjusting model mainly comprises a human-computer interaction interface, a category judgment module, a rearview mirror viewpoint position storage module and an API (application programming interface) calling module of Vega Prime.
