Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying 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, rather than all embodiments, and all other embodiments obtained by those skilled in the art based on the embodiments of the present invention belong to the scope of protection of the embodiments of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a display control method for a vehicle starry sky image according to an embodiment of the present invention, where the method includes:
s11, acquiring a current starry sky image and the current position of the vehicle, wherein the current starry sky image is a panoramic picture generated by shooting at different ground positions in real time.
Specifically, the current position may be obtained by communication Positioning between a vehicle-mounted GPS (Global Positioning System) and a satellite, and the panoramic image may be obtained by synthesizing images taken at different ground positions in real time. Referring to fig. 2, a plurality of starry sky pictures are shot in real time by a plurality of starry sky shooting towers at preset positions on the ground, each starry sky picture includes corresponding position information and time information, and a plurality of starry sky pictures shot by different starry sky shooting towers at the same time are synthesized to obtain a panoramic picture correspondingly. The panoramic picture can be stored in a starry sky picture library at the cloud, each vehicle is communicated with the starry sky picture library to obtain, and in order to ensure the accuracy of the current starry sky image, the current starry sky image is updated in real time according to the shooting time of a starry sky shooting tower, so that the current starry sky image can be updated to be the latest image in real time; the method specifically realizes that the current starry sky image and the current position can be obtained through an automobile controller inside the automobile. The process proceeds to step S12 after the current star field image and the current position are acquired.
And S12, determining a target starry sky image in the current starry sky image according to the current position.
Specifically, the current starry sky image is a panoramic image in the vehicle driving range, and the starry sky observation angles at different positions in the driving range are different, so that the observation results are different, and in order to ensure the accuracy of the vehicle observation at the current position, the current position can be used as the central position of the target starry sky image, and the display range of the vehicle ceiling display screen is the image boundary of the target starry sky image, so that the target starry sky image is determined in the current starry sky image.
When the target starry sky image is determined in the current starry sky image in specific implementation, due to the influence of the height of the poster, the determined target starry sky image and actual vehicle-outside observation do not correspond to each other.
In order to solve the above problem, in a specific embodiment, determining a target starry sky image in a current starry sky image according to a current position includes:
determining a target area in the current starry sky image according to the coordinate information of the current position; determining the scaling of a target area according to the altitude information, the correction coefficient and the image altitude information of the current position, wherein the image altitude information is the altitude of the current starry sky image; and determining the target area as a target starry sky image through the scaling processing result of the scaling.
Specifically, the coordinate information is a plane coordinate point in the current star field image corresponding to the current position, and the boundary of the target area can be determined according to the display range of the vehicle ceiling display screen. The image altitude information is the altitude of a plurality of ground different positions shot in real time, the altitude of each position may be different, and the starry sky shooting tower can be pre-positioned at the same altitude for shooting; of course, the time and the corresponding altitude of the picture shot by the starry sky shooting tower can be recorded first, and then the picture at the same time is synthesized into a panoramic picture, and the corresponding zooming is performed according to the altitude, and the zooming reference refers to the preset image altitude, namely the image altitude information. Since the altitude at which the vehicle travels may vary according to the road following, and there may be a difference between the altitude information of the current position and the image altitude information, the scaling of the target area may be determined by the altitude information, the correction coefficient, and the image altitude information. Wherein, the correction coefficient can be correspondingly set according to the difference between the altitude information and the image altitude information. It will be understood by those skilled in the art that the specific value set for the correction factor can be determined empirically by those skilled in the art, or can be calculated by calibration experiments. And after the target area is subjected to scaling processing according to the scaling ratio, a starry sky image consistent with the observation of the vehicle at the current position can be obtained, and the processing result is determined to be the target starry sky image.
The target area is determined in the current starry sky image through the coordinate information, the boundary of the target area needs to be calculated in a conventional mode, large calculation amount is involved, generally, hardware configuration of a ceiling display screen is low, calculation clamping stagnation is easily caused, and display updating delay of the ceiling display screen is caused.
In a specific embodiment, determining a target area in a current starry sky image according to coordinate information of a current position includes:
dividing the current starry sky image into a plurality of display areas according to the display specification of the ceiling display screen; and determining the area positioned in the coordinate information in the plurality of display areas as a target area.
Specifically, the display specification is the size of the display range of the ceiling display screen, the display area and the display specification of the ceiling display screen have a corresponding relationship, the current starry sky image is a panoramic picture and has a large starry sky range, and after the current starry sky image is divided into a plurality of display areas, the current starry sky image moves to the corresponding display areas along with the coordinate information, and the area is determined as a target area. The coordinate information may be a geographic coordinate, and the current position of the vehicle is represented by an astronomical longitude and latitude of the geographic coordinate.
In a specific embodiment, before determining the scaling of the target area according to the altitude information of the current position, the correction coefficient and the image altitude information, the method further comprises:
acquiring a first image of a first altitude position and a second image of a second altitude position, wherein the coordinate positions of the first altitude position and the second altitude position are both within a preset range of the current position, and the altitudes of the first altitude position and the second altitude position are different altitudes within the preset range; obtaining an image scaling value according to the ratio of the first image to the second image; and obtaining a correction coefficient according to the first elevation position, the second elevation position and the image scaling value.
Specifically, the first altitude position and the second altitude position may be different altitudes of the same coordinate position, or may be different altitudes within a preset range, and the calculated correction coefficient is not affected within the preset range. It can be understood that if the first elevation position is higher than the second elevation position, the field of view of the first image should be smaller than that of the second image, and the field of view included in the first image occupies a proportion of the second image, which is an image scaling value, the correction coefficient C may be calculated by the following formula:
x/(b-a), where X is the image scaling value, a is the altitude of the first elevation position, and b is the altitude of the second elevation position.
And S13, controlling the ceiling display screen of the vehicle to correspondingly display the starry sky image according to the target starry sky image.
Specifically, the ceiling display screen may be a thin film display screen or an optical fiber display screen, and the brightness of the star position in the target starry sky image is displayed on the ceiling display screen correspondingly. In the display process, the displayed starry sky image can be correspondingly rotated according to the steering direction of the vehicle, so that the starry sky image of the vehicle headspace can be accurately displayed.
In specific implementation, weather changes in real time, and in rainy weather, there may be no star in the current starry sky images shot and generated in real time at different positions on the ground, which may result in that a ceiling display screen inside the vehicle cannot display.
In order to solve the above problem, in a specific embodiment, before controlling a ceiling display of a vehicle to display a starry sky image according to a target starry sky image, the method further includes:
judging whether a starry sky image exists in the target display area or not; if not, controlling the ceiling display screen to correspondingly display a target hue and a target color temperature in the corresponding relation according to the current emotion index of the driver on the vehicle and a preset display corresponding relation, wherein the display corresponding relation is the corresponding relation between the emotion index and the hue and color temperature displayed by the ceiling display screen; and if so, executing the target starry sky image to control a ceiling display screen of the vehicle to correspondingly display the starry sky image.
Specifically, whether a starry sky image exists in the target display area or not is judged, the starry sky image can be compared with the target display area through a preset brightness threshold, if the brightness threshold is larger than the preset brightness threshold, the existence of the starry sky image is indicated, and the target starry sky image is executed to control a ceiling display screen of the vehicle to correspondingly display the starry sky image; if the current emotion index is not greater than the brightness threshold, the star-sky graph does not exist, and the star-sky graph is displayed according to the current emotion index of the driver and a preset display corresponding relation. It can be understood that the current emotion index can be preset by the operation of the driver through the in-vehicle entertainment system of the vehicle, for example, the current emotion index is divided into an array of 1-10, the current emotion index is 1-3, which indicates that the driver may be in a sad or angry emotional state, and the target color temperature is cold when the corresponding target color tone in the corresponding relationship is darker; the current emotion index is 4-6, which indicates that the driver is possibly in a calmer emotion state, and displays the corresponding target color tone and the original image of which the target color temperature is the starry sky image in the corresponding relation; the current emotion index is 7-10, which indicates that the driver is in a possible surprise or pleasant emotional state, and the brighter the corresponding target color tone in the correspondence is, the warmer the corresponding target color temperature is. The ceiling display screen is controlled to correspondingly display different tones and color temperatures through the current emotion index and the display corresponding relation, so that the comfort of drivers and passengers can be improved, and the display control of the space top in the automobile is more humanized.
In a specific embodiment, before controlling the ceiling display to correspondingly display the target color tone and the target color temperature in the display correspondence according to the current emotion index of the driver on the vehicle and the preset display correspondence, the method further includes:
acquiring the current facial expression and the current heart rate of a driver; and determining the current emotion index according to the current facial expression, the current heart rate and a preset weight coefficient.
Specifically, the current facial expression may be acquired by an image sensor in the vehicle, the current heart rate may be acquired by a heart rate sensor on the steering wheel, and the preset weight coefficient may include a weight coefficient corresponding to any one of the current facial expression or the current heart rate. Of course, weighting factors for both the current facial expression and the current heart rate may also be included, according to the formula:
K＝ω 1 m+ω 2 n; calculating to obtain a current emotion index K, wherein m is the current facial expression, n is the current heart rate, and omega 1 If the value of the weight parameter of the current facial expression m is larger, the influence of the current facial expression on the current emotion index is larger; omega 2 For the weight parameter of the current heart rate n, similarly, the larger the value is, the larger the influence of the current heart rate on the current emotion index is. As will be understood by those skilled in the art, ω is 1 And ω 2 Can be determined according to the set experience of a technician; or may be determined according to a test calibration test, which is not described herein. The facial expression and the heart rate of the driver are processed digitally, and then the accurate emotional index K is obtained through calculation of the weight coefficient.
