2 is a flowchart illustrating a method of adjusting the hue and brightness of the HUD system according to an embodiment of the present invention.
As shown in FIG. 2, the HUD module transmits coordinate information of the HUD to the ECU (S101), and the camera transmits coordinate information and an image of the measured image to the controller (S102).
The control unit matches the HUD and the camera coordinate system (S103). The position of the HUD screen displayed on the windshield is adjusted by the above process. Next, an area where the virtual screen of the HUD system is projected and displayed in the image input by the camera is designated as ROI (Region Of Interest) (S105), and dominant colors and brightness values in the ROI are calculated (S106).
That is, the pixel values of the area where the virtual screen of the HUD system is projected from the actual front background image input from the camera sensor are analyzed to obtain the dominant color value and the dominant brightness value of the corresponding area.
For this purpose, the pixel values (R, G, B format f RGB (x, y) = R f (x, y), G f (x, y) in arbitrary coordinates in the area where the virtual image of the HUD system is projected from the input image a, y), B f (x , y)} or YCbCr format f YCbCr (x, y) = {y f (x, y), Cb f (x, y), Cr f (x, y)} collar (hue Saturation, Intensity) HSI format using a conversion f HSI (x, y) = converted to {H f (x, y) , S f (x, y), I f (x, y)} , and the color (Hue) information, H f (x, y) a histogram of brightness (intensity) information I f (x, y) the dominant color values of the area in which the projected virtual display of the HUD system, from the histogram of the DH f (x, y) of And the dominant brightness value DI f (x, y).
At this time, according to the size of the information to be projected on the virtual screen of the HUD system, the predominant color value and brightness value are obtained in the two modes. In other words, it is possible to obtain one dominant color value and one dominant brightness value representative of the whole area of the virtual screen of the HUD system, or to overlap the projected area of the virtual screen of the HUD system ), And the dominant color value and the dominant brightness value can be obtained and applied to each window region, respectively.
One of the methods for executing S106 is to construct a color histogram by calculating the frequency of color values in a given area, and calculating the frequency histogram by calculating the frequency of the brightness values. The color value indicating the maximum frequency in the color histogram is selected as the predominant color value and the brightness value indicating the maximum frequency in the brightness histogram can be selected as the predominant brightness value.
It is also possible to use the maximum frequency within a certain range of the histogram as another specific methodology for obtaining dominant color values and dominant brightness values in a given area.
That is, the color histogram is constructed by obtaining the frequency of the color values in a given region, and the brightness histogram is constructed by obtaining the frequency of the brightness values. In the color histogram, the color values of the center of the window in which the sum frequency is maximum by summing the frequencies within the one-dimensional sliding window of a predetermined size (that is, within a certain color value range) are selected as predominant color values. In the brightness histogram, The brightness value representing the center of the window in which the frequency of the summation is maximum by summing the frequencies within the one-dimensional sliding window (i.e., within the predetermined brightness value range) is selected as the dominant brightness value.
Next, the vehicle transmits advanced driver assistance systems (ADAS) and navigation information to the HUD (S107). The HUD transmits the HUD color value to the controller (S108), and compares the color and brightness (S109).
Next, a new color value is set (S110). If the color of the screen displayed on the HUD virtual screen is the same as or similar to the color of the actual front background, the information provided through the HUD may not be displayed to the driver properly, thereby increasing the convenience and safety of the driver of the HUD system I can not do it. In order to simultaneously obtain driver's front view and intuitive recognition of the information provided by the HUD, the HUD system in which the color of the virtual screen of the HUD system is adaptively adjusted according to the color of the front background is indispensably required. To this end, the color value of the HUD virtual screen is automatically adjusted by comparing the predominant color value DH f (x, y) of the actual front background obtained in [claim 4] with the color value of the HUD virtual screen to be projected. For this purpose, the original pixel values of the HUD virtual screen (R, G, B format g RGB (x, y) = {R g (x, y), G g (x, y), B g (x, y)} or YCbCr format g YCbCr (x, y) = {y g (x, y), Cb g (x, y), Cr g (x, y)} to HSI format, using a color conversion g HSI (x, y ) = {H g (x, y), S g (x, y), I g (x, y)} to the conversion, and the actual dominant color value of the front background DHf (x, y) and the original HUD virtual screen color value H g (x, y) the comparison to obtain updated such that the complementary color (complementary color) when the same color or similar, dominant color value, a color value of the HUD virtual screen DHf (x, y) acceleration. newly obtained HUD The color value H g '(x, y) of the virtual screen is basically calculated by the following equation.
H g '(x, y) = H g (x, y) + α
αα
(X, y) and the brightness value Ig (x, y) of the newly obtained HUD virtual screen and the inverse transform of the original saturation value Sg pixel value (R, G, B format, g 'RGB = {R' g (x, y), G 'g (x, y), B' g (x, y)} or YCbCr format g 'YCbCr (x, (x, y) = {Y ' g (x, y), Cb' g (x, y) and Cr ' g
The color value H ' g (x, y) of the new HUD virtual screen can be obtained using the following equation.
H 'g (x, y) = H g (x, y) + ω H × sign (H g (x, y) -DH g (x, y)) × (δ max -min (│Hg (x, y) -DHg (x, y) |,? max )
In the above equation, ω H is a constant value that can control the intensity of the complementary color, and the range of the value is 0 ≤ H ≤ 1, and min (A, B) means the minimum value of the two values. Also, δ max means the maximum value of complementary colors that can be added / subtracted when DHf (x, y) and Hg (x, y) are the same.
Next, the illuminance information measured by the illuminance sensor is transmitted to the controller (S111). The controller calculates a brightness value based on the information (S112) and sets a new brightness value (S113).
If the brightness of the virtual screen of the HUD system during nighttime operation is too strong, it will cause the driver's glare to obstruct the view of the front view. If the brightness of the virtual screen is weak, It becomes difficult to recognize in a short time.
HUD system in which the brightness value of the virtual screen of the HUD system is adaptively adjusted according to the brightness of the front background is indispensably required. To do this, the brightness value is adjusted by comparing the dominant brightness value DIf (x, y) of the actual front background with the brightness value of the HUD screen to be projected.
Pixel value of the HUD screen (R, G, B format g RGB (x, y) = {R g (x, y), G g (x, y), B g (x, y)} or YCbCr format g YCbCr (x, y) = {y g (x, y), Cb g (x, y), Cr g (x, y)} to the conversion, and screen brightness S111 the value I g (x, y) of the actual front If the same as the dominant intensity values of the background DI f (x, y), or similar, so that they can be distinguished from the intensity values of the HUD display superior brightness DI f (x, y). for this purpose, the brightness of the adjustment HUD screen The value I'g (x, y) is calculated by adding the dominant brightness value DI f (x, y) of the actual background to the brightness value I g (x, y) of the first HUD screen as shown in the following equation It is obtained by multiplying the proportional constant ω CDS proportional to the illuminance of the illuminance sensor.
I 'g (x, y) = ω CDS × I g (x, y) + DI f (x, y) ....... equation (3)
Brightness values of the adjusted HUD screen I'g (x, y) and the initial color values Hg (x, y) (or the modified color values H 'g (x, y) ) and saturation value S g (x, y) consisting of g 'HSI (x, y) = {H g (x, y) or H' g (x, y) , S g (x, y), I 'g (x, y)} the inverse color transform (inverse transform) to the new pixel value of the HUD screen (R, g, B format, g 'RGB (x, y) = {R' g (x, y), g 'g (x, y), B' g ( x, y)} or apply obtained the YCbCr format g 'YCbCr (x, y) = {y' g (x, y), Cb 'g (x, y), Cr' g (x, y)}.
The brightness value and the hue value obtained in the above process are changed (S114), and the result is outputted to the HUD (S115).
