As an object of the present invention, the present invention provides an intelligent display control method for an LED intelligent lamp pole, which can be applied to a smart city, wherein the intelligent lamp pole includes at least one display screen, in the embodiment of the present invention, the display screens each adopt an LED full-color display screen, and corresponding display contents and display modes of the display screen are further determined and controlled in a targeted manner based on determination of different positions of the intelligent lamp pole, so that targeted contents can be provided for different people, and intelligent display of the intelligent lamp pole is realized, specifically, as shown in fig. 1, the method includes the steps of:
s1: the method can obtain the position information of each intelligent lamp pole in a remote mode, or input the position information of each intelligent lamp pole in a corresponding installation of a control device which is arranged in each intelligent lamp pole and comprises a processor, so that the method can obtain the position information of each intelligent lamp pole in a local mode by reading the position information in the memory.
S2: and determining to receive corresponding display contents and display modes according to the obtained position information, and using the obtained position information, determining that the intelligent lamp poles at different positions respectively and correspondingly receive different display contents and determining corresponding different display modes with different display contents.
S3: and controlling the display screen to play the display content according to the display mode, and receiving the play content and the display mode determined in the steps through a control device arranged in each intelligent lamp post or a control device which is provided with the display screen and has LAN and WIFI communication functions, so that the two display content can be displayed in an optimal display mode in a matched mode.
By the intelligent display control method of the LED intelligent lamp post, the display screens at different positions can be dynamically and intelligently controlled to intelligently display required specific contents, so that targeted contents can be provided for different crowds watching the display contents, such as pedestrians, drivers, waiting persons and the like, and the requirements of an urban lighting system on intellectualization, civiliation and diversification are met. As an implementation manner of the foregoing remote communication and control adopted by the intelligent display control method for the smart lamp pole according to the embodiment of the present invention, for example, the gateway of the smart lamp pole sends information of the monitoring device to the cloud server, and simultaneously, for example, the remote control platform or a computer with special control software, especially a portable notebook computer, performs external communication with the cloud server through a network, sends a control command to the cloud server, and can obtain real-time status of each smart lamp pole as a terminal, so as to realize intelligent display of a display screen of the smart lamp pole controlled by the remote control command. In road traffic management, traffic warning signs provided on a road-top guideboard are often used to warn drivers of passing vehicles. Under the condition of better visibility in daytime, a driver can clearly see the traffic reminding sign on the guideboard. However, in the case of low visibility in dusk or at night, it is not easy to see traffic reminding signs of the guideboard. In this regard, the smart light pole in this embodiment may be disposed near a traffic road, and the relevant traffic reminding sign is displayed by using the display screen on the smart light pole.
As shown in fig. 2, the step S3: before controlling the display screen 11 to play the display content according to the display mode, the method further comprises:
s301: detecting whether a vehicle passes or not;
specifically, whether or not a vehicle passes through the detected area may be detected using a radar, a video image, or the like.
S302: if yes, acquiring a traffic reminding mark image according to the vehicle position information as the current display content;
when the monitored area is detected to pass through the vehicle, the position of the vehicle is immediately acquired. And selecting a proper traffic reminding mark image from the traffic reminding mark image database according to the position of the vehicle for displaying.
For example, road guidance images and speed limitation images may be displayed when the vehicle is located far away. The lane distribution image may be displayed when the vehicle position is close. An arrow image of the traveling direction can be displayed when the vehicle is positioned very close.
S303: detecting whether the vehicle position information is updated;
since the vehicle position is in rapid change, it is necessary to continuously track the position of the vehicle and update the position information of the vehicle at a sufficiently short interval.
S304: determining whether a traffic reminding mark image needs to be switched or not according to the updated vehicle position information when the vehicle position information is updated;
The step judges whether the current position of the vehicle enters the position where the traffic reminding sign needs to be replaced according to the updated position information of the vehicle.
The method specifically comprises the following steps:
acquiring vehicle position partition data;
the vehicle position partition data comprises a plurality of position sections and traffic reminding sign images corresponding to the position sections. The distance from the vehicle to the intelligent lamp post can be divided into a plurality of parts, and each part is a position section. For example, the area between the lamp posts a1 to a2 is the 1 st part, for example, the area between the lamp posts a2 to a3 is the 2 nd part, for example, the area between the lamp posts a3 to a4 is the 3 rd part.
Determining a position partition where the current vehicle is located according to the updated vehicle position information and the vehicle position partition data;
for example, if the vehicle is located at a position a1 < b1 < a2 from the lamp post b1, the current position of the vehicle is divided into a2 nd part.
And acquiring traffic reminding marks corresponding to the position partitions where the current vehicle is located according to the vehicle position partition data.
For example, the current position of the vehicle is partitioned into a2 nd part, and the traffic reminding mark corresponding to the second part is a lane guiding mark.
And comparing whether the corresponding traffic reminding mark is the same as the currently displayed traffic reminding mark, if so, switching the traffic reminding mark image, and if not, not switching.
S305: if yes, acquiring a new traffic reminding mark image according to the new vehicle position information to serve as the current display content.
By adopting the scheme, the displayed traffic reminding sign can be timely adjusted according to the position of the vehicle, so that a driver can obtain the most accurate and timely reminding information at different positions.
As shown in fig. 3, the step S304: the method for determining whether to switch the traffic reminding mark image according to the updated vehicle position information when the vehicle position information is updated further comprises the following steps:
s306: if the traffic reminding mark image does not need to be switched, determining an image adjustment strategy according to the updated vehicle position information;
if the vehicle does not enter a new section, the display screen 11 may continue to display the original traffic warning sign image, but the size, angle, brightness, etc. of the warning sign image may not always be in a state most suitable for the driver to observe because the position of the vehicle is continuously changing. For this embodiment, the image displayed on the display screen 11 can be adjusted with the latest vehicle position.
For example, if the current vehicle position is far away, the image adjustment strategy is to enlarge the image and lighten it; if the current vehicle position is close, the image adjustment strategy is to dim the image down.
S307: and determining the adjusted size and/or brightness of the traffic reminding mark image according to the image adjustment strategy to obtain an intermediate image.
This step keeps the displayed traffic alert sign unchanged but adjusts the size and/or angle and/or brightness of the image.
S308: acquiring ambient brightness information;
s309: adjusting the brightness of the intermediate image according to the ambient brightness information to obtain a target image 30;
the present embodiment also adjusts the brightness of the surrounding environment of the display screen 11 according to the image displayed on the display screen 11, if the surrounding environment is brighter, the brightness of the image is lower, and if the surrounding environment is darker, the brightness of the image is higher. As an alternative but advantageous embodiment, the display screen 11 is an irregularly curved screen in this example; the screen is irregularly curved, and the images can be displayed from different angles, so that the angle displayed by the traffic reminding sign image can be flexibly adjusted according to the position of the vehicle in the embodiment. However, since the ideal reminding mark image is an image displayed when the screen is in a planar state, the original effect cannot be displayed if the original image data is directly applied to the irregular curved surface screen, and since the viewing angle of the driver relative to the irregular curved surface screen is also changed along with the different positions of the vehicle, it is difficult to ensure the consistency of the display effect of the traffic reminding mark image.
As shown in fig. 4, in this embodiment, the step S307: the method further comprises the steps of after determining the size and/or the angle and/or the brightness of the traffic reminding mark image according to the image adjustment strategy to obtain an intermediate image:
s3071: acquiring updated position information of the vehicle;
s3072: determining a virtual plane 40 which is matched with the position of the vehicle according to the updated position information of the vehicle, wherein the virtual plane 40 is perpendicular to a connecting line between a smart lamp pole reference point and the current position of the vehicle and is a preset distance away from the vehicle;
in order to achieve the ideal display effect, the present embodiment first assumes that a flat screen is placed at a position most suitable for the driver's observation, and displays the traffic warning sign image on the screen with the best effect. The plane on which the screen is located is the virtual plane 40 described above.
S3073: acquiring a virtual image 20 displayed on the virtual plane 40 by the intermediate image according to the intermediate image and the virtual plane 40;
as shown in fig. 6, the present embodiment assumes that the intermediate image is displayed at the position of the virtual plane 40, and the image that works best when displayed at that position is taken as the virtual image 20. For example, when the intermediate image is displayed on the virtual plane 40, the driver can most comfortably observe the image displayed on the virtual plane 40 by adjusting the size, brightness, and other factors of the intermediate image, and the intermediate image is obtained as the virtual image 20 through the adjustment.
S3074: the target image 30 on the display screen 11 corresponding to the virtual image 20 is determined according to the projection relationship of the virtual plane 40 and the display screen 11.
As shown in fig. 7, since the position of the display screen 11 of the present embodiment is not on the ideal virtual plane 40, and the position of the display screen 11 with respect to the driver is constantly changing, and the display screen 11 is a curved surface screen, if the traffic warning sign image is directly displayed with the data of the virtual image 20, the effect of the virtual image 20 cannot be achieved, and the display effect is constantly changing with the change of the vehicle position. In this embodiment, the virtual image 20 is converted according to the projection relationship between the virtual plane 40 and the display screen 11 to obtain the target image 30, so that the traffic reminding sign image on the display screen 11 seen by the vehicle at each position is closest to the ideal effect of the virtual image 20 when displayed on the virtual plane 40.
The method specifically comprises the following steps:
acquiring the position relationship among the vehicle, the virtual plane 40 and the display screen 11;
since the position of the driver in the vehicle is almost unchanged, the position of the eyes of the driver can be obtained according to the position of the vehicle, and thus the positional relationship between the vehicle and the display screen 11 can be obtained in this step. Since the virtual plane 40 is set in advance, the relative position of the virtual plane 40 and the eyes of the driver after setting is also kept unchanged.
Each pixel of the virtual image 20 is projected to a corresponding pixel position on the display screen 11 according to the positional relationship of the three, and the pixel value of the corresponding pixel position on the display screen 11 is determined.
Wherein the pixels of the virtual image 20 are represented by a rectangle. The specific projection method uses a preset reference point as an origin, wherein the preset reference point can adopt an optimal position for the human eye to see the virtual image 20.
As shown in fig. 8, the origin and the edges of the pixels of the virtual image 20 will be connected separately by lines which form a series of intersections on the display screen 11. The area surrounded by the intersections is the area on the display screen 11 corresponding to the pixel, and the pixels on the display screen 11 in the corresponding area are the pixels corresponding to the virtual image 20.
One pixel of the virtual image 20 may occupy one pixel position on the display screen 11 or may occupy a plurality of pixel positions when projected onto the display screen 11. If a pixel position on the display screen 11 is occupied, the pixel value of the pixel position is the pixel value of the pixel of the projected virtual image 20, for example, the pixel P1 of the virtual image 20 in fig. 8 corresponds to 4 pixels P11, P12, P13, and P14 after being projected on the display screen 11. If multiple pixel locations are occupied, then the pixel values of the multiple pixel locations are all the pixel values of the projected virtual image 20 pixels.
It is also possible that a plurality of pixels of the virtual image 20 are projected onto the same pixel position of the display screen 11, and the pixel value of the pixel position is an average value of the pixel values of the respective projected pixels. For example, n pixels of the virtual image 20 are projected onto the same pixel position on the display screen 11, and assuming that the pixel value of the i-th pixel in the n pixels is Ri, the pixel value of the same pixel position on the display screen 11 is (r1+r2+ … … +rn)/n.
Assuming that the i-th pixel occupies an area of the same pixel position on the display panel 11 as Si, the pixel value of the same pixel position on the display panel 11 is (r1×s1+r2×s2+ … … +rn×sn)/(s1+s2+ … … +sn).
Pixels on the display screen 11 having pixel values other than 0 are combined into the target image 30.
After all the pixels of the virtual image 20 have been projected onto the display screen 11, the pixel values for each pixel location on the display screen 11 are determined. Since the pixel having the pixel value of 0 is not displayed, only the pixels other than 0 are combined into the target image 30.
The method combines the characteristic that the irregular curved surface screen can display images from multiple angles, and the step images of the traffic images are displayed as the target image 30 closest to the ideal effect, so that drivers can continuously and stably observe the traffic reminding sign images with the optimal display effect when the vehicles are at different positions.
Since the above method uses the curved display screen to display, the distance between the different pixel positions on the display screen 11 and the driver is different, and the brightness observed by the driver is lower when the pixels are far under the same brightness, so that the curved display screen 11 generates brightness distortion when displaying the image. In addition, after the position of the vehicle is changed, the distance between the image and the driver is changed, and in the method, although the traffic reminding sign image is displayed in the most proper size and angle, the brightness of the image cannot meet the requirement of ideal effect.
Further adjustments are made to the brightness of individual pixels of the target image 30 for this embodiment,
the S3074: determining the target image 30 on the display screen 11 corresponding to the virtual image 20 according to the projection relationship of the virtual plane 40 and the display screen 11 further includes:
s30741: acquiring a reference distance dc;
as shown in fig. 9, wherein the reference distance dc may be the shortest distance of the display screen 11 from the virtual plane 40;
s30742: determining the shortest distance di of each first pixel on the display screen 11 from the virtual plane 40 according to the projection relation between the virtual plane 40 and the display screen 11;
s30743: calculating a distance difference dr for each first pixel from dc and di, wherein dr = dc-di;
S30744: acquiring a brightness adjustment coefficient k (dr) corresponding to each first pixel according to the distance difference dr of each first pixel;
wherein the brightness adjustment coefficient k (dr) is a function of dr, which can be determined experimentally. In the experiment, a sensor is arranged at a set position, the light-emitting unit is moved along a straight line from the position of the distance sensor dc to a distance, and the brightness of the light-emitting unit detected by the sensor is recorded when the light-emitting unit is at different positions. Assuming that the luminance of the light emitting unit at the position of the sensor dc is the initial luminance L0 and the luminance of the light emitting unit at the distance from the initial position di is Li, k (dr) =li/L0 when dr=di. And fitting k (dr) values at different positions of the light emitting unit to obtain a function curve of k (dr).
S30745: the luminance of each pixel in the target image 30 is adjusted according to the original luminance Lr of the first pixel and the corresponding luminance adjustment coefficient, lz=k (dr) ×lr, where Lz is the luminance of the first pixel after adjustment.
Wherein the original luminance Lr of the first pixel is the luminance of the target image 30 pixels before adjustment. By adopting the method to adjust the brightness of each pixel on the display screen 11, the brightness error caused by the difference of the distance between each pixel on the curved surface screen and the driver can be compensated, so that the brightness of the image is close to the optimal display effect.
