s1: the method comprises the steps that position information of the intelligent lamp poles is obtained, wherein the position information can be geographic position numbers of a certain street, an area and a place in a city, for example, each intelligent lamp pole can be networked with a control center, such as a smart city, with a cloud server through 5G communication and can receive corresponding communication and control, so that the position information of each intelligent lamp pole can be obtained in a remote mode, the place information correspondingly installed on each intelligent lamp pole can be input into a memory in a control device, such as a processor, which is arranged in each intelligent lamp pole, and the position information of each intelligent lamp pole can be obtained through reading the place information in the memory in a local mode.
S2: the corresponding display content and the corresponding display mode are determined and received according to the obtained position information, and by means of the obtained position information, the intelligent lamp posts in different positions can be determined in a targeted mode to correspondingly receive different display contents and determine the corresponding different display modes with the different display contents.
S3: the display screen is controlled to play the display content according to the display mode, the playing content and the display mode determined in the above steps can be received through a control device configured in each intelligent lamp pole or a control device with the display screen and LAN and WIFI communication functions, and the playing content and the display mode are matched with each other and the display content is displayed in an optimal display mode.
According to the intelligent display control method of the intelligent lamp post, the display screens at different positions can be dynamically and intelligently controlled to intelligently display the required specific content, so that targeted content can be provided for different people such as pedestrians, drivers, waiting people and the like who watch the displayed content, and the requirements of an urban lighting system on intellectualization, familiarity and diversification are met.
As an implementable manner of the above-mentioned remote communication and control adopted by the intelligent display control method of the smart lamp post according to the embodiment of the present invention, for example, the gateway of the smart lamp post sends the information of the monitoring device to the cloud server, and meanwhile, for example, the remote control platform or a computer, especially a laptop computer, with dedicated control software performs external communication with the cloud server through a network, sends a control instruction to the cloud server, and can obtain a real-time state of each smart lamp post serving as a terminal, thereby implementing the intelligent display of the display screen of the smart lamp post controlled by the remote control instruction. In road traffic management, drivers of passing vehicles are often reminded by using traffic reminding signs arranged on guideboards above roads. Under the condition of better visibility in daytime, drivers can clearly see the traffic reminding marks on the guideboards. But the traffic reminding sign of the guideboard is not easy to be seen under the condition of low visibility at night or dusk. Therefore, the intelligent lamp pole in the embodiment can be arranged near a traffic road, and the display screen on the intelligent lamp pole is used for displaying the related traffic reminding mark.
As shown in fig. 2, the S3: before controlling the display screen 11 to play the display content according to the display mode, the method further includes:
s301: detecting whether a vehicle passes through;
specifically, whether a vehicle passes through the detected area may be detected using radar, video images, or the like.
S302: if so, acquiring the traffic reminding mark image as the current display content according to the vehicle position information;
when the vehicle passing through the monitored area is detected, 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.
The road guidance image and the speed limit image may be displayed when the vehicle is located far away, for example. The lane distribution image may be displayed when the vehicle position is close. An arrow image of the traveling direction may be displayed when the vehicle position is close.
S303: detecting whether the vehicle position information is updated;
since the vehicle position is in rapid change, the position of the vehicle needs to be continuously tracked and updated at sufficiently short intervals.
S304: when the vehicle position information is updated, determining whether the traffic reminding sign image needs to be switched according to the updated vehicle position information;
and judging whether the current position of the vehicle enters the position where the traffic reminding mark needs to be replaced or not 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 mark images corresponding to the position sections. The realization can divide into a plurality of parts with the distance of vehicle apart from wisdom lamp pole, and every part is a position section. For example, the region between the lamp posts a1 to a2 is the 1 st section, the region between the lamp posts a2 to a3 is the 2 nd section, and the region between the lamp posts a3 to a4 is the 3 rd section.
Determining a position zone where the current vehicle is located according to the updated vehicle position information and the vehicle position zone data;
for example, the vehicle is located at a position a1 < b1 < a2 away from the lamp post b1, the current position of the vehicle is divided into the 2 nd part.
And acquiring the traffic reminding mark corresponding to the position partition where the current vehicle is located according to the vehicle position partition data.
For example, the current vehicle is located in the position zone of the 2 nd part, and the traffic reminding mark corresponding to the second part is the lane guiding mark.
And comparing whether the corresponding traffic reminding mark is the same as the currently displayed traffic reminding mark or not, if so, switching the images of the traffic reminding mark, and if not, switching is not needed.
S305: and if so, acquiring a new traffic reminding mark image as the currently displayed content according to the new vehicle position information.
By adopting the scheme, the displayed traffic reminding mark can be adjusted in time according to the position of the vehicle, so that drivers can obtain the most accurate and timely reminding information at different positions.
As shown in fig. 3, the S304: when the vehicle position information is updated, whether the traffic reminding mark image is switched or not is determined according to the updated vehicle position information, and the method further comprises the following steps:
s306: if the traffic reminding mark images do 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 mark image, but the size, angle, brightness, etc. of the warning mark image may not always be in a state most suitable for the driver to observe because the position of the vehicle is continuously changed. For this embodiment, the image displayed on the display screen 11 can be adjusted by the latest vehicle position.
For example, if the current vehicle position is far, the image adjustment strategy is to adjust the image to be large and bright; if the current vehicle position is closer, the image adjusting strategy is to turn down and dim the image.
S307: and determining the adjusted size and/or brightness of the traffic reminding mark image according to the image adjusting 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: obtaining ambient brightness information;
s309: adjusting the brightness of the intermediate image according to the environment brightness information to obtain a target image 30;
the present embodiment further adjusts the image displayed on the display screen 11 according to the brightness degree of the environment around the display screen 11, wherein if the environment is bright, the brightness of the image is decreased, and if the environment is dark, the brightness of the image is increased. As an alternative but advantageous embodiment, in the present embodiment the display screen 11 is an irregular curved screen; the screen is an irregular curved surface, and the angle displayed by the traffic warning mark image can be flexibly adjusted according to the position of the vehicle in the embodiment because the screen can display images from different angles. However, since the ideal warning mark image is an image displayed when the screen is in a planar state, if the original image data is directly applied to the irregular curved screen, the original effect cannot be displayed, and since the viewing angle of the driver with respect to the irregular curved screen is also changed with the difference in the vehicle position, it is difficult to ensure the consistency of the display effect of the traffic warning mark image.
As shown in fig. 4, in this embodiment, the S307: after the size and/or angle and/or brightness of the traffic reminding mark image after adjustment is determined according to the image adjustment strategy to obtain an intermediate image, the method further comprises the following steps:
s3071: acquiring updated position information of the vehicle;
s3072: determining a virtual plane 40 adapted to 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 the intelligent lamp post reference point and the current position of the vehicle and is away from the vehicle by a preset distance;
in order to achieve an ideal display effect, the present embodiment assumes that a planar screen is placed at a position most suitable for the driver to observe, and displays the traffic alert sign image on the screen with the best effect. The plane of the screen is the virtual plane 40.
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 in a position of the virtual plane 40, and the image that performs best when displayed in this position is taken as the virtual image 20. For example, when the intermediate image is displayed on the virtual plane 40, the driver can observe the image displayed on the virtual plane 40 most comfortably by adjusting the size, brightness, etc. of the intermediate image, which is obtained as the virtual image 20 through the above adjustment.
S3074: and determining the target image 30 corresponding to the virtual image 20 on the display screen 11 according to the projection relation 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, the position of the display screen 11 relative to the driver is changing, and the display screen 11 is a curved screen, if the data of the virtual image 20 is directly used to display the traffic warning mark image, the effect of the virtual image 20 cannot be achieved, and the display effect is changing with the change of the vehicle position. In this embodiment, the virtual image 20 is converted to obtain the target image 30 according to the projection relationship between the virtual plane 40 and the display screen 11, so that the traffic warning mark image on the display screen 11 seen by the vehicle at each position is closest to the ideal effect when the virtual image 20 is displayed on the virtual plane 40.
The method specifically comprises the following steps:
acquiring the position relation 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 therefore 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 remains unchanged after the setting.
And projecting each pixel of the virtual image 20 to a corresponding pixel position on the display screen 11 according to the position relationship of the three, and determining a pixel value of the corresponding pixel position on the display screen 11.
Wherein the pixels of the virtual image 20 are represented by a rectangle. The specific projection method is to use a preset reference point as an origin, wherein the preset reference point can be the best position for human eyes 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 by straight lines, respectively, which form a series of intersections on the display screen 11. The area surrounded by these intersections is the area corresponding to the pixel on the display screen 11, and the pixel on the display screen 11 in the corresponding area is the pixel corresponding to the virtual image 20.
One pixel of the virtual image 20 may occupy one pixel position or may occupy multiple pixel positions on the display screen 11 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 onto the display screen 11. If multiple pixel locations are occupied, the pixel values of these multiple pixel locations are all the pixel values of the projected virtual image 20 pixels.
Further, if a plurality of pixels of the virtual image 20 are projected onto the same pixel position of the display panel 11, the pixel value at that pixel position may be the average of the pixel values of the projected pixels. For example, if n pixels of the virtual image 20 are projected to the same pixel position on the display screen 11 and the pixel value of the ith pixel of the n pixels is Ri, the pixel value of the same pixel position on the display screen 11 is (R1 + R2+ \ 8230; \8230; + Rn)/n.
Assuming that the area of the ith pixel occupying the same pixel position on the display screen 11 is Si, the pixel value of the same pixel position on the display screen 11 is (R1 × S1+ R2 × S2+ \8230; + Rn × Sn)/(S1 + S2+ \8230; + 8230; + Sn).
Pixels on the display screen 11 with pixel values other than 0 are combined into the target image 30.
After all the pixels of the virtual image 20 are projected onto the display screen 11, the pixel values of the respective pixel positions on the display screen 11 are determined. Since the pixels having the pixel value of 0 are not displayed, only the pixels other than 0 are combined into the target image 30.
The method adopted by the embodiment combines the characteristic that the irregular curved screen can display images from multiple angles, and displays the traffic image step images as the target images 30 closest to the ideal effect, so that the driver can continuously and stably observe the traffic reminding sign images with the optimal display effect when the vehicle is at different positions.
Because the curved-surface display screen is used for displaying, the distance between different pixel positions on the display screen 11 and the driver is different, and the brightness observed by the driver is lower when the pixel is farther under the same brightness, so that the curved-surface display screen 11 may generate brightness distortion when displaying images. And after the position of the vehicle is changed, the distance between the image and the driver is changed, and although the traffic reminding mark image is displayed at the most appropriate size and angle by the method, the brightness of the image cannot meet the requirement of ideal effect.
For this embodiment the brightness of the individual pixels of the target image 30 is further adjusted,
the step S3074: determining the target image 30 corresponding to the virtual image 20 on the display screen 11 according to the projection relationship between 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 between each first pixel on the display screen 11 and 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 of 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;
where the brightness adjustment coefficient k (dr) is a function with respect to dr, which can be determined experimentally. During the experiment, a sensor is arranged at a set position, the light-emitting unit moves along a straight line from a position away from the sensor dc, and the brightness of the light-emitting unit detected by the sensor is recorded when the light-emitting unit is at different positions. When the luminance of the light-emitting unit at the position of the sensor dc is set as the initial luminance L0 and the luminance of the light-emitting unit at the position di from the initial position is set as Li, k (dr) = Li/L0 is obtained when dr = di. And fitting the k (dr) values of the light-emitting units at different positions to obtain a function curve of the 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 adjusted luminance of the first pixel.
Wherein the original luminance Lr of the first pixel is the luminance of 30 pixels of the target image before adjustment. By adopting the method to adjust the brightness of each pixel on the display screen 11, the brightness error caused by the distance difference between each pixel on the curved screen and the driver can be compensated, so that the brightness of the image is close to the optimal display effect.
