Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

Fig. 1 is a flowchart of an anti-ghosting method based on a vehicle-mounted display terminal according to an embodiment of the present invention. As shown in fig. 1, the method for preventing a ghost image based on a vehicle-mounted display terminal according to the embodiment of the present invention includes the following steps:
s1: and acquiring the eye position information of the current driver, and converting the eye position information into eye position coordinate information.
According to one embodiment of the invention, the eye position information of the current driver is acquired through a human eye position sensor arranged on a steering wheel.
It should be noted that, as shown in fig. 2, the human eye position sensor may be disposed on the steering wheel, so that when the anti-back-reflection function is turned on, the current driver's eye position information is obtained through the human eye position sensor, and the current driver's eye position information is converted into eye position coordinate information according to the current driver's eye position information, where the position coordinate may be (x, y, z) three-dimensional coordinate data. When the steering wheel is not in the positive position, the eye position sensor can determine the current eye position information of the driver according to the rotation angle of the steering wheel, and the positive position of the steering wheel is the direction of the steering wheel when the wheels move forwards along a straight line.
S2: and acquiring contour coordinate information of a display area of the vehicle-mounted display terminal and contour coordinate information of a transparent area of the front windshield.
It should be noted that the contour coordinate information of the display area of the vehicle-mounted display terminal may be preset in advance, that is, the contour information of the display area of the vehicle-mounted display terminal is determined when the vehicle leaves the factory, and the contour coordinate information of the display area of the vehicle-mounted display terminal is determined according to the vertical screen state or the horizontal screen state of the vehicle-mounted display terminal. The contour coordinate information of the display area of the vehicle-mounted display terminal can be (x, y, z) three-dimensional coordinate data.
That is, the current eye position information of the driver acquired through the eye position sensor and the determination of the display area of the display terminal may be in the same coordinate system to further determine whether reflection generated by the display area is reflected to the eyes of the driver.
S3: and acquiring a first display area of the display area, which generates a reflection on the transparent area and reflects the reflection to the current eyes of the driver according to the eye position coordinate information, the contour coordinate information of the display area and the contour coordinate information of the transparent area.
According to one embodiment of the invention, a reflection generated by the display area in the transparent area is obtained according to the outline coordinate information of the display area and the outline coordinate information of the transparent area; acquiring a first reflection area reflected to the eyes of the current driver by the reflection according to the reflection and the coordinate information of the positions of the eyes; and determining the display area corresponding to the first reflection area as a first display area according to the first reflection area.
It should be noted that, according to the principle of planar imaging, the display area may produce a reflection on the windshield, and the reflection may fall into a transparent area of the windshield, that is, the reflection of the display area on the windshield coincides with the transparent area, and further, the coinciding reflection may be reflected to the eyes of the driver by light reflection, where the coinciding reflection is generated by the first display area.
Specifically, as shown in fig. 3, the display area of the vehicle-mounted display terminal may be divided into a certain number of dot matrixes, then an inverted image of each dot matrix in a transparent area is obtained, whether a reflection light of the inverted image of the dot matrix can be reflected to the eyes of the current driver is judged, then an inverted image set that the reflection light of the inverted image can be incident to the eyes of the current driver is obtained, the inverted image set is a first inverted image area, and a display area corresponding to the inverted image set is obtained through the inverted image set, that is, the first display area.
Alternatively, as shown in fig. 4, after obtaining the inverted image of each dot matrix in the transparent area on the front windshield, the inverted image coordinates of each dot matrix are matched with the boundary coordinates of the transparent area, and if the inverted image coordinates identical to the boundary coordinates of the transparent area can be obtained, the corresponding dot matrix is determined from the inverted image having the inverted image coordinates identical to the boundary of the transparent area, and then the area between the dot matrix and the upper edge of the display area is determined as the first display area.
It should be noted that, when calculating the reflection of the display area generated in the transparent area on the windshield, it is necessary to recognize the state of the in-vehicle display terminal, such as the landscape screen state or the portrait screen state, and then calculate the reflection according to the state of the in-vehicle display terminal.
S4: and adjusting the display area of the vehicle-mounted display terminal to display through the residual display area except the first display area in the display area.
As shown in fig. 5, the content to be displayed is displayed in the remaining area of the display area excluding the first display area, so as to avoid the first display area from generating reflection to the eyes of the driver and affecting the visual field of the driver.
According to one embodiment of the invention, the method for preventing the vehicle-mounted display terminal from the reverse image also detects the light intensity of the current environment of the vehicle, and starts the automatic reverse image prevention function of the vehicle-mounted display terminal when the light intensity is smaller than a preset value.
It should be noted that, when the light of the current environment is strong, the light emitted from the display area of the on-board display terminal cannot produce a reflection, and thus the light reflected to the eyes of the driver cannot be produced, wherein it can be determined whether the headlight of the vehicle is turned on, that is, if the headlight of the vehicle is turned on, it is determined that the light intensity of the current environment of the vehicle is less than the preset threshold, and if the headlight of the vehicle is not turned on, it is determined that the light intensity of the current environment of the vehicle is greater than or equal to the preset threshold. In other words, whether the headlights of the vehicle are turned on or not is judged, if the headlights of the vehicle are turned on, the automatic anti-reflection function of the vehicle-mounted display terminal is controlled to be turned on, and if the headlights of the vehicle are not turned on, the automatic anti-reflection function of the vehicle-mounted display terminal is controlled to be turned off.
Specifically, the vehicle-mounted display terminal can be provided with a headlamp opening detection device for detecting an opening signal of a vehicle headlamp, if the opening signal of the vehicle headlamp is detected, the automatic anti-reflection function of the vehicle-mounted display terminal is further controlled to be opened, and if the opening signal of the vehicle headlamp is not detected, the automatic anti-reflection function of the vehicle-mounted display terminal is controlled to be kept closed.
According to one embodiment of the invention, a user instruction is received through a display interface of the vehicle-mounted display terminal so as to start the automatic anti-back-reflection function of the vehicle-mounted display terminal.
It should be understood that sometimes, although the reflection of the image in the display area of the vehicle-mounted display terminal is not reflected to the eyes of the driver, the driver may dislike the reflection of the image on the windshield to affect the sight line due to his personal preference, and at this time, the driver may issue an instruction to start the automatic anti-reflection function of the vehicle-mounted display terminal through the display interface of the vehicle-mounted display terminal, so as to start the automatic anti-reflection function of the vehicle-mounted display terminal.
According to one embodiment of the invention, when the vehicle is in the automatic driving mode, the automatic anti-back-reflection function of the vehicle-mounted display terminal can be automatically turned off. When the vehicle is in the automatic driving mode, the requirement of the driver on the front road condition is reduced, the requirement on the multimedia entertainment system is increased, namely the automatic reflection prevention mode of the vehicle-mounted display terminal is closed, so that the vehicle-mounted display terminal can work in a full display area, the requirement of the driver is met, and the user experience is improved.
According to an embodiment of the present invention, as shown in fig. 6, an anti-ghosting method based on a vehicle-mounted display terminal according to an embodiment of the present invention includes the following steps:
s101: the human eye position sensor identifies the position of the eyes of the driver, namely the current eye position coordinate information of the driver.
S102: a transparent area of the front windshield is obtained.
S103: and calculating the reflection of the display area on the front windshield according to the eye position coordinate information and the contour coordinate information of the display area.
S104: and judging whether the inverted image and the transparent area have an overlapping area.
If yes, executing step S105; if not, step S107 is performed.
S105: and calculating the size of the overlapping area, and further determining the size of the first display area.
S106: the display area is controlled to display in a size in which the first display area is excluded from the display area.
S107: normally, the display is performed in the full display area.
In summary, according to the method for preventing ghosting based on the vehicle-mounted display terminal provided by the embodiment of the invention, firstly, the eye position information of the current driver is acquired, and the eye position information is converted into the eye position coordinate information, then, the contour coordinate information of the display area of the vehicle-mounted display terminal and the contour coordinate information of the transparent area of the windshield are acquired, the first display area of the display area, which generates ghosting on the transparent area and is reflected to the current driver's eyes, is acquired according to the eye position coordinate information, the contour coordinate information of the display area and the contour coordinate information of the transparent area, and the display area of the vehicle-mounted display terminal is adjusted, so that the remaining display area except the first display area in the display area is displayed. Therefore, the method for preventing the reverse image can automatically adjust the size of the display area, so that the display area forming the reverse image on the transparent area of the front windshield does not emit light, and the problem that the driver views the reverse image on the front windshield by the vehicle-mounted display screen can be effectively solved. Meanwhile, the eye position information of the current driver is introduced, personalized adjustment can be performed on the driver, and the user experience is improved.
The invention also provides a non-transitory computer readable storage medium, on which a computer program is stored, which when executed by a processor implements the method for preventing ghosting based on the vehicle-mounted display terminal.

According to one embodiment of the present invention, the first obtaining module 10 obtains the current eye position information of the driver through an eye position sensor 11 disposed on the steering wheel.
It should be noted that, as shown in fig. 2, the human eye position sensor 11 may be disposed on the steering wheel, so that when the anti-back-reflection function is turned on, the current driver's eye position information is acquired by the human eye position sensor 11, and is converted into eye position coordinate information according to the current driver's eye position information, where the position coordinate may be (x, y, z) three-dimensional coordinate data. When the steering wheel is not in the right position, the eye position sensor 11 can determine the eye position information of the driver according to the rotation angle of the steering wheel, and the right position of the steering wheel is the direction of the steering wheel when the wheels move forward along a straight line.
It should be further noted that the contour coordinate information of the display area of the on-board display terminal 50 may be preset in advance, that is, the contour information of the display area of the on-board display terminal 50 is determined when the vehicle leaves the factory, and the contour coordinate information of the display area of the on-board display terminal 50 is determined according to the portrait screen state or the landscape screen state of the on-board display terminal 50.
