The Head-Up Display system (HUD) is also called a Head-Up Display system and is used for projecting important driving information such as the speed per hour, navigation and the like of a vehicle onto a windshield in front of a driver, so that the driver can see the important driving information such as the speed per hour, the navigation and the like without lowering the Head and turning the Head, the distraction of the driver is reduced as much as possible, and the driving safety is improved. However, the HUD is a part of the vehicle interior hardware, and is fixed to the vehicle body. In the driving process, because the automobile body jolts, cause the hardware to rock slightly, then cause HUD's display image to produce and rock for the human eye perception, the driver is watching behind the display image who rocks, and the vertigo is felt to appear easily, has reduced navigating mate's driving safety nature.
Referring to fig. 1, the present invention provides an application structure diagram of an automatic adjusting method of a head-up display image. The vehicle or meter information collecting module 110 collects vehicle surrounding environment information and meter information such as speed of time and navigation information. The camera module 120 detects the relative position change between the displayed image and the fixed reference object to obtain the position deviation data, and determines whether the displayed image has a shake or an offset. The vehicle or meter information collecting module 110 and the camera module 120 transmit vehicle surrounding environment information and meter information such as a speed per hour, navigation information, estimated shaking position information of a displayed image, and position deviation data of the displayed image to the data processing module 130 through, for example, a Controller Area Network (CAN) bus. After receiving the related information, the data processing module 130 analyzes the image information to be displayed and analyzes the coordinate information of the display image that needs to be adjusted and changed according to the position deviation data, and then transmits the image information to be displayed and the coordinate information of the display image that needs to be adjusted and changed to the display screen drawing module 140. The display screen drawing module 140 performs drawing and calibration adjustment of the display screen according to the information transmitted from the data processing module 130, and then transmits the display screen after drawing to the coordinate system conversion module 150. The coordinate system conversion module 150 performs coordinate system conversion on the drawn display screen to convert the display screen into a display image suitable for forward projection on the windshield, and then transmits the display image after the coordinate system conversion is completed to the image display module 160. The image display module 160 projects and displays the display image after the calibration adjustment on the front windshield.
Referring to fig. 2, fig. 2 is a flowchart illustrating an automatic adjusting method for a head-up image according to an exemplary embodiment of the present application, which can be applied to the application structure of the automatic adjusting method for a head-up image shown in fig. 1 and is mainly executed by the camera module 120 in the application environment. It should be understood that the method can also be applied to other exemplary implementation application structures and specifically executed by the camera module 120 in other implementation application environments, and the embodiment does not limit the application structure to which the method is applied.
Referring to fig. 2, in an embodiment of the present invention, an automatic adjusting method for a head-up display image includes the following steps:
step S210 is to set a fixed reference object and obtain initial relative position data of the display image and the fixed reference object.
The fixed reference object should be a plurality of objects or marked points with obvious shapes in the vehicle, such as a fixed point on a front windshield or a fixed point on an instrument panel, and the specific position of the fixed reference object is not limited in the application. When the initial relative position data of the display image and the fixed reference object is obtained, the display image needs to be initially adjusted to obtain the initially adjusted display image. Then, one or more fixed reference points are selected from the displayed image, and the reference points do not select the points at which the image edge is displayed as the reference points, because the image edge may not display information, the camera module 120 may not recognize the point location when shooting, which causes the failure of automatic adjustment. After the fixed reference object in the vehicle and the reference point in the initially adjusted display image are acquired, the camera module 120 performs shooting, and after the shooting, the calculation processor in the camera module 120 first establishes a three-dimensional coordinate system by using the position of the fixed reference object as an origin, and then determines the coordinate positions in the three-dimensional coordinate system corresponding to the plurality of fixed reference points on the display image.
Then, the calculation processor in the camera module 120 calculates the coordinate positions in the three-dimensional coordinate system according to the plurality of fixed reference points on the display image and obtains the initial relative position data of the display image and the fixed reference object. The initial relative position data comprises the length of a connecting line between the position coordinates of the fixed reference object and the position coordinates of the reference points in the image and an included angle between the connecting line and a coordinate axis. In addition, when the fixed reference object in the vehicle is blocked or the front of the vehicle encounters strong light, the image shot by the camera module 120 cannot obviously capture the position of the fixed reference object, and the camera module 120 actively captures other fixed hardware in the vehicle in the camera image as the fixed reference object. The camera module 120 selectively uses a reference object that is relatively obvious in the picture as a fixed reference object position at the next shooting.
Step S220, the position of the displayed image is monitored in real time, and the real-time relative position data of the fixed reference object and the displayed image is obtained.
The camera module 120 performs real-time shooting detection on the display image, and the real-time shooting includes performing uninterrupted shooting according to the frame rate of the display image no matter when the vehicle is idle or when the vehicle is shaken, or observing a road surface through a camera outside the vehicle body to perform predictive analysis so as to determine whether the shaking trigger the camera module 120, or starting triggering the camera module 120 when the shaking occurs and performing uninterrupted shooting according to the frame rate of the display image. When the camera module 120 takes a real-time image, a three-dimensional coordinate system is always established with the position of a single fixed reference object as an origin, the coordinate position in the coordinate system corresponding to the fixed reference object on the real-time image is continuously obtained, and the processor in the camera module 120 calculates and obtains the real-time relative position data of the image and the fixed reference object. The real-time relative position data comprises the length of a connecting line of the position coordinates of the fixed reference object and the position coordinates of the reference point in the image and an included angle between the connecting line and a coordinate axis.
In step S230, the position deviation data of the displayed image is obtained according to the initial relative position data and the real-time relative position data.
The position deviation data of the display image comprises deviation lengths and deviation angles of the initial relative position and the real-time relative position.
Step S240, determining whether the position deviation data is greater than a set threshold, if the position deviation data is greater than the set threshold, executing step S250, and if the position deviation data is less than or equal to the set threshold, executing step S220.
Wherein the set threshold includes a set deviation length and a set deviation angle, and when the plurality of position deviation data are compared with the set distance difference and the set angle difference, respectively, and at least one of the deviation length and the deviation angle in the position deviation data is greater than the set deviation length or the set deviation angle in the set threshold, S250 is performed. If both the deviation length and the deviation angle in the positional deviation data are less than or equal to the deviation length and the deviation angle in the set threshold value, step S220 is performed. The length and angle of deviation in setting the threshold values may be, for example, up to one or more pixel size, i.e., the camera module 120 of the present invention may monitor and adjust the display image shaking to the pixel level.
In step S250, the display image is adjusted according to the position deviation data.
After the camera module 120 determines that the position deviation data is greater than the set threshold, the position deviation data is transmitted to the data processing module 130 through the CAN bus, the angle and the position of the display screen are adjusted according to the position deviation data, the display image is adjusted through the display screen drawing module 140, and the image is displayed on the front windshield through the coordinate system conversion module 150 and the image display module 160.
Referring to fig. 3, in an embodiment of the invention, a method for adjusting a displayed image includes the following steps:
step S310, position deviation data and vehicle body or instrument information are acquired.
Referring to fig. 1, the vehicle or meter information collection module 110 and the camera module 120 transmit vehicle surrounding environment information and meter information, such as speed per hour, navigation information, and position deviation data of a display image, to the data processing module 130 through, for example, a Controller Area Network (CAN) bus.
Step S320, analyzing and obtaining coordinate information of the display image that needs to be adjusted and changed according to the position deviation data.
Referring to fig. 1, after receiving the related information, the data processing module 130 analyzes the image information to be displayed and analyzes the coordinate information of the display image that needs to be adjusted according to the position deviation data.
And step S330, drawing the adjusted display image according to the information of the vehicle body or the instrument and the coordinate information of the display image needing to be adjusted and changed.
Referring to fig. 1, the data processing module 130 transmits image information to be displayed and coordinate information of the display image that needs to be adjusted and changed to the display image drawing module 140, and the display image drawing module 140 draws the adjusted display image.
Step S340, performing coordinate system conversion on the adjusted display image to obtain the adjusted display image.
Referring to fig. 1, the coordinate system conversion module 150 performs coordinate system conversion on the rendered display image, wherein the display image adjusted by the display image rendering module 140 is stored in the memory in the form of pixel coordinates. The coordinate system conversion module 150 converts the display image stored in the form of pixel coordinates into a display image in the form of an image coordinate system or a camera coordinate system, and thus converts the display image into a display image suitable for forward projection on the windshield.
In step S350, the adjusted display image is displayed.
The coordinate system conversion module 150 transmits the display image after the coordinate system conversion is completed to the image display module 160. The image display module 160 projects and displays the display image after the calibration adjustment is completed on the front windshield.
Referring to fig. 4, in an embodiment of the present invention, an automatic adjusting method of a head-up display image further includes the following steps:
and S410, acquiring road condition information in front of the vehicle by observing the road surface.
