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 apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments, and all other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the embodiments of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a method for controlling display of a star field image of a vehicle according to an embodiment of the present invention, where the method includes:
s11, acquiring a current starry sky image and the current position of a vehicle, wherein the current starry sky image is a panoramic picture generated by shooting a plurality of different ground positions in real time.
Specifically, the current position can be obtained through communication positioning between a vehicle-mounted GPS (Global Positioning System ) and satellites, and the panoramic picture can be obtained through synthesis of pictures taken in real time at a plurality of different ground positions. Referring to fig. 2, a plurality of star-sky pictures are shot in real time by a plurality of star-sky shooting towers at preset positions on the ground, each star-sky picture contains corresponding position information and time information, and the plurality of star-sky pictures shot by different star-sky shooting towers at the same time are synthesized to correspondingly obtain panoramic pictures. The panoramic pictures can be stored in a star-sky picture library of the cloud, and each vehicle is communicated with the star-sky picture library to obtain, so that the accuracy of the current star-sky image is ensured, the current star-sky image is updated in real time according to the shooting time of a star-sky shooting tower, and the current star-sky image can be updated into the latest image in real time; the method specifically comprises the step of acquiring the current star field image and the current position through an automobile controller in the automobile. After the current star field image and the current position are acquired, the process proceeds to step S12.
S12, determining a target starry sky image in the current starry sky image according to the current position.
Specifically, because the current star field image is a panoramic image in the running range of the vehicle, and the viewing angles of the star field observed at different positions in the running range are different, so that the observed results are different, in order to ensure the accuracy of the vehicle in the current position observation, the current position can be used as the center position of the target star field image, and the display range of the vehicle ceiling display screen is the image boundary of the target star field image, so that the target star field image is determined in the current star field image.
When the target star sky image is determined in the current star sky image, the determined target star sky image and the actual outside-vehicle observation are not corresponding to each other due to the influence of the height of the poster.
In order to solve the above problem, in a specific embodiment, determining a target star field image from the current star field image according to the current position includes:
determining a target area in the current star image according to the coordinate information of the current position; determining the scaling of the 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 a scaling processing result of the target area after scaling as a target starry sky image.
Specifically, the coordinate information is that the current position corresponds to a planar coordinate point in the current star field image, 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 photographed in real time at a plurality of different ground positions, the altitude at each position may be different, and the star-sky photographing tower can be pre-addressed to the same altitude for photographing; of course, the zooming reference refers to the preset image altitude, namely the image altitude information, according to the time when the star photographing tower photographs the pictures and the corresponding altitude are recorded first, and then when the pictures at the same time are combined into the panoramic picture, the corresponding zooming is carried out according to the altitude. Since the altitude at which the vehicle travels may vary according to the road following, there may be a difference between the altitude information of the current position and the image altitude information, and thus the scaling of the target area may be determined by the altitude information, the correction coefficient, and the image altitude information. The correction coefficient may be set according to the difference between the altitude information and the image altitude information. Those skilled in the art will appreciate that the specific values for the correction factor settings may be determined based on the experience of the skilled person or may be calculated by calibration experiments. And (3) after the target area is scaled according to the scaling, a star field figure consistent with the observation of the vehicle at the current position can be obtained, and the processing result is determined to be the target star field figure.
The target area is determined in the current star field image through the coordinate information, the boundary of the target area needs to be calculated in a conventional mode, large calculation amount is involved, the hardware configuration of the ceiling display screen is generally low, calculation clamping stagnation is easy to cause, and display update of the ceiling display screen is delayed.
In a specific embodiment, determining the target area in the current star field image according to the coordinate information of the current position includes:
dividing a current starry sky image into a plurality of display areas according to the display specification of a ceiling display screen; the region located in the coordinate information among the plurality of display regions is determined as a target region.
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 larger starry sky range, the current starry sky image is divided into a plurality of display areas, and after the current starry sky image is moved to the corresponding display areas along with the coordinate information, the areas are determined as target areas. The coordinate information may be geographic coordinates, and the current position of the vehicle is represented by the longitude and latitude of the astronomy of the geographic coordinates.
In a specific embodiment, before determining the scaling of the target area according to the altitude information, the correction coefficient and the image altitude information of the current position, the method further comprises:
acquiring a first image of a first elevation position and a second image of a second elevation position, wherein the coordinate positions of the first elevation position and the second elevation position are in a preset range of a current position, and the altitude of the first elevation position and the altitude of the second elevation position are different altitudes in 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 altitude position is higher than the second altitude position, the field of view of the first image is smaller than that of the second image, and the field of view of the first image is the scale value of the second image, and the correction coefficient C can be calculated by the following formula:
c=x/(b-a), where X is the image scaling value, a is the altitude of the first altitude, and b is the altitude of the second altitude.
And S13, controlling a 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 can be a thin film display screen or an optical fiber display screen, and the brightness of the star position in the target star sky image is correspondingly displayed on the ceiling display screen. In the display process, the displayed starry sky image can be correspondingly rotated according to the steering direction of the vehicle so as to accurately display the starry sky image of the vehicle head space.
In the implementation, because weather can change in real time, in overcast and rainy weather, the current star sky image generated by shooting at different positions on the ground in real time may not have a star image, which causes that a ceiling display screen in the vehicle cannot be displayed.
In order to solve the above problem, in a specific embodiment, before controlling the ceiling display of the vehicle to correspondingly display the starry sky image according to the target starry sky image, the method further includes:
judging whether a starry sky image exists in the target area; if not, controlling a ceiling display screen to correspondingly display a target tone and a target color temperature in the corresponding display 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 color temperature of the tone displayed by the ceiling display screen; if yes, 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 a target area is judged, a brightness threshold value can be preset to be compared with the target area, if the brightness threshold value is larger than the preset brightness threshold value, the starry sky image exists, and the starry sky image is correspondingly displayed by controlling a ceiling display screen of the vehicle according to the target starry sky image; and if the current emotion index of the driver is not greater than the brightness threshold, indicating that no star pattern exists, and displaying the current emotion index of the driver according to a preset display corresponding relation. It can be understood that the current emotion index can be preset through the operation of the driver through the car 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, the emotion state of the driver which may be sad or anger is illustrated, the darker the corresponding target color tone in the corresponding relation is displayed, and the corresponding target color temperature is cool; the current emotion index is 4-6, which indicates that the driver is in a calm emotion state, and the corresponding target tone and target color temperature in the corresponding relation are displayed as original pictures of the starry sky image; the current emotion index is 7-10, which indicates that the driver may be in a surprise or pleasant emotion state, and the brighter the corresponding target color temperature in the corresponding relation is displayed, the warmer the corresponding target color temperature is. The ceiling display screen is controlled to correspondingly display different hues and color temperatures through the corresponding relation between the current emotion indexes and the display, so that the comfort of drivers and passengers can be improved, and the control of the star-sky top display in the vehicle is more humanized.
In a specific embodiment, before controlling the ceiling display to display the target color tone and the target color temperature in the corresponding 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 a current emotion index according to the current facial expression, the current heart rate and the preset weight coefficient.
Specifically, the current facial expression may be acquired through an image sensor in the vehicle, the current heart rate may be acquired through 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 and the current heart rate. Of course, the weight coefficients of 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 a current facial expression, n is a current heart rate, omega 1 The larger the value of the weight parameter of the current facial expression m is, the larger the influence of the current facial expression on the current emotion index is explained; omega 2 And the same applies to the weight parameter of the current heart rate n, and the larger the value is, the larger the influence of the current heart rate on the current emotion index is. As will be appreciated by those skilled in the art, ω 1 And omega 2 Can be determined according to the setting experience of technicians; and can also be determined according to experimental calibration tests, which are not described in detail herein. The facial expression and heart rate of the driver are digitally processed, and then the accurate pre-emotion index K is calculated through the weight coefficient.
