Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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 is a schematic flow chart of a fault recovery method for a vehicle-mounted display device according to an embodiment of the present invention.
The fault recovery method for the vehicle-mounted display equipment provided by the embodiment comprises the following steps:
and S11, acquiring a current interface displayed on the vehicle-mounted display equipment.
S12, calculating a region RGB difference value between a preset region of the current interface and the preset region of a standard interface; and the standard interface is an interface displayed when the vehicle-mounted display equipment is not in fault.
And S13, controlling the vehicle-mounted display equipment to carry out fault recovery when the RGB difference value of the area exceeds a preset threshold value.
Illustratively, all or part of the area displaying correct and invariable characters or graphs can be selected as a preset area in an interface displayed when the vehicle-mounted display device does not have a fault, so that the accuracy of fault detection is ensured.
It should be noted that the RGB difference value of the region is an absolute value. In specific implementation, the preset threshold may be set according to the required fault detection accuracy, which is not limited herein, and optionally, in this embodiment, the preset threshold is 0.
It can be understood that the difference value between the RGB of the preset regions in the two interfaces can be used to represent the degree of similarity between the preset regions in the two interfaces, and the larger the difference value between the RGB of the preset regions in the two interfaces is, the lower the degree of similarity between the preset regions in the two interfaces is, whereas the smaller the difference value between the RGB of the preset regions in the two interfaces is, the higher the degree of similarity between the preset regions in the two interfaces is. In the display process of the vehicle-mounted display device, because the standard interface is an interface displayed when the vehicle-mounted display device is not in fault, if the difference value of the RGB of the area between the preset area of the current interface and the preset area of the standard interface is too large, it is indicated that the similarity degree of the preset areas in the two interfaces is low, at this time, the vehicle-mounted display device is most likely to cause display dislocation due to the fault problems of scrolling and screen splitting.
It should be noted that, in the display process of the vehicle-mounted display device, the failure recovery method provided in this embodiment may be continuously operated to continuously monitor whether the scroll split failure occurs, and if the scroll split failure occurs again, the recovery mechanism may be executed again, thereby ensuring the normal operation of the vehicle-mounted display device.
As an optional embodiment, the method further comprises:
and when the RGB difference value of the area does not exceed the preset threshold value, controlling the vehicle-mounted display equipment to keep the current working state.
It can be understood that, in this embodiment, when it is determined that the difference value between the RGB of the area does not exceed the preset threshold, it indicates that the similarity degree of the preset areas in the two interfaces is higher, and the possibility of the fault problems of the vehicle-mounted display device, such as screen scrolling and screen splitting, is very low, so that the vehicle-mounted display device is controlled to maintain the current working state, thereby maintaining the normal operation of the vehicle-mounted display device.
As one optional embodiment, the calculating the difference value between the RGB areas of the preset area of the current interface and the preset area of the standard interface includes:
s121, extracting the RGB value of each pixel point in the preset area of the current interface to obtain a target RGB set;
s122, calculating the RGB difference value of each pixel point in the preset area between two interfaces according to the target RGB set and a pre-acquired standard RGB set; the standard RGB set comprises RGB values of all pixel points in the preset area of the standard interface;
and S123, solving the sum of the RGB difference values of each pixel point in the preset area to obtain the regional RGB difference value.
In step S122, the RGB difference value is an absolute value. Illustratively, for each pixel point in the preset area, according to the target RGB set and a pre-obtained standard RGB set, RGB values of the pixel point in the current interface and the standard interface are respectively obtained, and then the RGB value of the pixel point in the current interface and the RGB value of the pixel point in the standard interface are subtracted and an absolute value is taken, so as to obtain an RGB difference value of the pixel point between the two interfaces.
In a specific embodiment, the standard RGB set is obtained by: when the vehicle-mounted display equipment does not break down, selecting a pixel point at the lower left corner of a screen of the vehicle-mounted display equipment as an origin O, taking the pixel point as an x axis along the horizontal direction of the screen and taking the pixel point as a y axis along the vertical direction of the screen, and establishing a plane rectangular coordinate system x-O-y; and based on the plane rectangular coordinate system x-O-y, sequentially acquiring and recording the coordinates and RGB values of all pixel points in the preset area according to a set sequence by taking the first pixel point at the upper left corner of the preset area as a starting point, and generating a standard RGB set.
For example, in step S123, the calculation formula of the region RGB difference value may be:
As an optional embodiment, the preset area is an outer contour area of the identification control extracted from the standard interface.
In this embodiment, the outer contour region of the identification control extracted from the standard interface displayed when the vehicle-mounted display device fails is used as the preset region, so that the calculation amount of the RGB difference values of the region can be reduced, the consumption of calculation resources is reduced, and the efficiency of fault detection is improved.
As a specific implementation manner, a specific flow of the method for recovering the fault of the vehicle-mounted display device provided in this embodiment may refer to fig. 2, which is not described herein again.
As an optional embodiment, when it is determined that the RGB difference value of the area exceeds the preset threshold, the controlling the vehicle-mounted display device to perform fault recovery includes:
and when the RGB difference value of the area exceeds a preset threshold value, outputting a restarting signal to a video deserializer of the vehicle-mounted display equipment, so that the video deserializer is initialized again and loads the content to be displayed.
It should be noted that, referring to fig. 3, in general, the vehicle-mounted display device includes a vehicle machine, a video deserializer, and a screen. The car machine is a host connected with the screen in the car and used for receiving a string video stream transmitted from the outside; the video deserializer is a video deserializer chip at a vehicle end and is used for deserializing a serialized video stream which is transmitted from the outside and enters the vehicle; the screen is a central control display screen and is used for displaying the video stream deserialized by the video deserializer. In the display process of the vehicle-mounted display device, if the video deserializer fails, the problem of screen scrolling and screen splitting of the interface displayed on the screen can be caused, and therefore, in the embodiment, when the difference value of the RGB in the region exceeds the preset threshold value, the restart signal is output to the video deserializer of the vehicle-mounted display device, so that the video deserializer is reinitialized and loads the content to be displayed, the video deserializer can be effectively enabled to recover the normal working state, and the problem of screen scrolling and screen splitting in the display process of the vehicle-mounted display device is solved.
It should be noted that the fault recovery method for the vehicle-mounted display device provided in this embodiment and the preferred embodiments thereof may be applied to different vehicle use scenarios, and is particularly applicable to parking scenarios, and not only can detect whether the vehicle-mounted display device has the problem of screen scrolling and screen splitting, but also can quickly control the vehicle-mounted display device to perform fault recovery when the problem of screen scrolling and screen splitting occurs, so that not only can developers and after-sales maintenance personnel reduce the time for positioning the problem, but also the time and cost for the user to maintain the vehicle can be reduced, the stability for the user to use the vehicle is greatly improved, and the fault rate of the vehicle is reduced.
