As an object of the present invention, the present invention provides an intelligent display control method of a smart light pole, which can be applied in a smart city. The smart light pole includes at least one display screen. In the embodiments of the present invention, the display screens all use LED The full-color display screen, based on the determination of the different positions of the smart light pole, further determines and controls the corresponding display content and display mode of the display screen, so that it can provide targeted content for different groups of people and realize the smart light pole. The intelligent display of the pole, specifically, as shown in Figure 1, the method includes steps:

S1: Obtain the location information of the smart light pole. The location information can be the geographic location number of a certain street, area, or place in the city, so that each smart light pole can communicate with a cloud server such as a smart phone through 5G communication. The city's control center is connected to the network and accepts corresponding communication and control, so that the method of the present invention can obtain the location information of each smart light pole remotely, or through the built-in control device of each smart light pole, for example, including a processor. The memory of each smart light pole is input with the location information correspondingly installed, so that the method of the present invention can read the location information in the memory in a local way to obtain the location information of each smart light pole.

S2: Determine and receive the corresponding display content and display mode according to the obtained position information. Using the obtained position information, it can be targeted to determine that the smart light poles in different positions receive different display content and determine to display them in different ways. The content corresponds to different display modes.

S3: Control the display screen to play the display content according to the display mode. The control device configured in each smart light pole or the control device that comes with the display screen and has LAN and WIFI communication functions can receive the above steps. The determined playback content and display mode are matched so that the display content can be displayed in an optimal display mode.

Due to the intelligent display control method of the smart light pole of the present invention, it is possible to dynamically and intelligently control the display screens at different positions to intelligently display the specific content required, so as to provide pedestrians, drivers, waiting people, etc., with different views of the displayed content. The crowd provides targeted content to meet the needs of urban lighting systems for intelligence, people-friendliness and diversification.

As an implementable mode of the above-mentioned remote communication and control adopted by the intelligent display control method of the intelligent light pole in the embodiment of the present invention, for example, the gateway of the intelligent light pole sends the information of the monitoring equipment to the cloud server, and at the same time, for example, the remote The control platform or a computer with special control software, especially a laptop, communicates externally with the cloud server through the network, sends control commands to the cloud server and can obtain the real-time status of each smart light pole as a terminal, and realizes remote control commands to control The smart display of the display screen of the smart light pole. In road traffic management, the traffic reminder signs arranged on the road signs above the road are often used to remind the drivers of passing vehicles. In the case of good visibility during the day, drivers can clearly see the traffic warning signs on the road signs. However, in the case of low visibility at dusk or at night, it is not easy to see the traffic warning signs on the road signs. In this regard, the smart light pole in this embodiment can be installed near the traffic road, and the display screen on the smart light pole can be used to display relevant traffic warning signs.

As shown in FIG. 2 , before the S3: controlling the display screen 11 to play the display content according to the display mode, it also includes:

S301: Detect whether there is a vehicle passing through;

Specifically, radar, video images, etc. may be used to detect whether there is a vehicle passing through the detection area.

S302: If yes, acquire the image of the traffic warning sign according to the vehicle location information as the current display content;

When a vehicle is detected passing through the monitoring area, the location of the vehicle is immediately acquired. And according to the position of the vehicle, the appropriate traffic warning sign image is selected from the traffic warning sign image database for display.

For example, road guidance images and speed limit images can be displayed when the vehicle is far away. The lane distribution image can be displayed when the vehicle position is close. An arrow image for the direction of travel can be displayed when the vehicle is in close proximity.

S303: Detect whether the vehicle location information is updated;

Since the position of the vehicle is changing rapidly, it is necessary to continuously track the position of the vehicle and update the position information of the vehicle within a sufficiently short interval.

S304: When the vehicle location information is updated, determine whether it is necessary to switch the image of the traffic warning sign according to the updated vehicle location information;

In this step, it is judged whether the current position of the vehicle has entered the position where the traffic warning sign needs to be replaced according to the updated position information of the vehicle.

Specifically include the following steps:

Obtain vehicle location partition data;

The vehicle location zoning data includes several location sections and the corresponding traffic warning sign image for each location section. The realization can divide the distance between the vehicle and the smart light pole into several parts, and each part is a location segment. For example, the area between a1 and a2 is the first part, for example the area between a2 and a3 is the second part, and for example the area between a3 and a4 is the third part.

Determine the location partition where the current vehicle is located according to the updated vehicle location information and vehicle location partition data;

For example, the vehicle is located at a position a1<b1<a2 away from the light pole b1 at this time, and the current position of the vehicle is divided into the second part.

Obtain the traffic reminder sign corresponding to the location partition where the current vehicle is located according to the vehicle location partition data.

For example, the current location of the vehicle is divided into the second part, and the traffic warning sign corresponding to the second part is the lane guidance sign.

It is compared whether the corresponding traffic warning sign is the same as the currently displayed traffic warning sign, if they are the same, the image of the traffic warning sign needs to be switched, and if not, the switching is not required.

S305: If yes, acquire a new traffic warning sign image as the currently displayed content according to the new vehicle location information.

After adopting the foregoing scheme, the displayed traffic warning sign can be adjusted in time according to the position of the vehicle, so that the driver can obtain the most accurate and timely reminder information at different positions.

As shown in FIG. 3 , after the S304: determining whether to switch the image of the traffic warning sign according to the updated vehicle position information when the vehicle position information is updated, it also includes:

S306: If there is no need to switch the image of the traffic warning sign, determine an image adjustment strategy according to the updated vehicle position information;

If the vehicle does not enter a new section, the display screen 11 can continue to display the original traffic warning sign image, but because the position of the vehicle is constantly changing, the size, angle, brightness, etc. of the warning sign image will not always be at the optimum level. A state suitable for the driver to observe. In this embodiment, the latest vehicle position can be used to adjust the image displayed on the display screen 11 .

For example, if the current vehicle position is far away, the image adjustment strategy is to make the image larger and brighter; if the current vehicle position is closer, the image adjustment strategy is to make the image smaller and darker.

S307: Determine the adjusted size and/or brightness of the image of the traffic warning sign according to the image adjustment strategy to obtain an intermediate image.

In this step, the displayed traffic reminder sign remains unchanged, but the size and/or angle and/or brightness of the image are adjusted.

S308: Obtain ambient brightness information;

S309: Adjust the brightness of the intermediate image according to the ambient brightness information to obtain the target image 30;

In this embodiment, the image displayed on the display screen 11 is adjusted corresponding to the brightness of the surrounding environment of the display screen 11. If the environment is brighter, the brightness of the image is lowered, and if the environment is darker, the brightness of the image is increased. As an optional but advantageous implementation, in this embodiment, the display screen 11 is an irregularly curved screen; this type of screen becomes an irregularly curved surface, and since this type of screen can display images from different angles, it can In this embodiment, the displayed angle of the image of the traffic warning sign is flexibly adjusted according to the position of the vehicle. But because the ideal warning sign image is the image displayed when the screen is in a flat state, if the original image data is directly applied to the irregular curved screen, the original effect cannot be displayed, and due to the different positions of the vehicle, the driver The viewing angle of the relatively irregular curved screen is also changing, so it is difficult to ensure the consistency of the image display effect of the traffic reminder sign.

As shown in FIG. 4 , for this, in this embodiment, said S307: after determining the adjusted size and/or angle and/or brightness of the image of the traffic reminder sign according to the image adjustment strategy, after obtaining the intermediate image, it also includes:

S3071: Obtain the updated location information of the vehicle;

S3072: Determine the virtual plane 40 adapted to the position of the vehicle according to the updated position information of the vehicle, the virtual plane 40 is perpendicular to the line between the reference point of the smart light pole and the current position of the vehicle, and is a preset distance from the vehicle distance;

In order to achieve an ideal display effect, this embodiment first assumes that a flat screen is placed at the most suitable position for the driver to observe, and the image of the traffic warning sign is displayed on the screen with the best effect. The plane where the screen is located is the aforementioned virtual plane 40 .

S3073: Acquire the 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 , in this embodiment, it is assumed that the intermediate image is displayed at the position of the virtual plane 40 , and the image with the best effect when displayed at this position is used 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 and brightness of the intermediate image.

S3074: Determine 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 .

As shown in Figure 7, since the position of the display screen 11 of this embodiment is not on the ideal virtual plane 40, and the position of the display screen 11 relative to the driver is constantly changing, and the display screen 11 is a curved screen, if the virtual screen 11 is used directly Using the data of the image 20 to display the image of the traffic warning sign cannot achieve the effect of the virtual image 20, and the display effect is constantly changing with the change of the vehicle position. To this end, this embodiment converts the virtual image 20 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 sign images on the display screen 11 seen by the vehicle at various positions are all consistent with The ideal virtual image 20 has the closest effect when displayed on the virtual plane 40 .

Specifically include the following steps:

Obtain the positional relationship among the vehicle, the virtual plane 40 and the display screen 11;

Since the position of the driver in the vehicle is almost constant, the position of the driver's eyes can be obtained according to the position of the vehicle, so this step can also obtain the positional relationship between the vehicle and the display screen 11 . Since the virtual plane 40 is preset, the relative position between the virtual plane 40 and the eyes of the driver remains unchanged after setting.

Project each pixel of the virtual image 20 to a corresponding pixel position on the display screen 11 according to the positional relationship among the three, and determine the pixel value of the corresponding pixel position on the display screen 11 .

The pixels of the virtual image 20 are represented by a rectangle. The specific projection method is to use a preset reference point as the origin, wherein the preset reference point can adopt the best position for human eyes to see the virtual image 20 .

As shown in FIG. 8 , several straight lines are used to respectively connect the origin and the edge of 20 pixels of the virtual image, and these straight lines form a series of intersection points on the display screen 11 . The area enclosed by these intersection points is the area on the display screen 11 corresponding to the pixel, and the pixels on the display screen 11 located in the corresponding area are the pixels corresponding to the virtual image 20 .

When a pixel of the virtual image 20 is projected onto the display screen 11, it may occupy one pixel position on the display screen 11, or may occupy multiple pixel positions. If it occupies a pixel position on the display screen 11, then the pixel value of the pixel position is the pixel value of the pixel of the projected virtual image 20, for example, after the pixel p1 of the virtual image 20 is projected onto the display screen 11 in FIG. The four pixels P11, P12, P13, and P14. If multiple pixel positions are occupied, the pixel values of these multiple pixel positions are all pixel values of 20 pixels of the projected virtual image.

In addition, it is also possible that multiple pixels of the virtual image 20 are projected to the same pixel position of the display screen 11 , and the pixel value of the pixel position is the average value of the pixel values of the projected pixels. For example, n pixels of the virtual image 20 are projected to the same pixel position on the display screen 11, if the pixel value of the i-th pixel in the n pixels is Ri, then the pixel value of the same pixel position on the display screen 11 is (R1+R2+...+Rn)/n.

Assuming that the area of the i-th pixel occupying the same pixel position on the display screen 11 is Si, then the pixel value of the same pixel position on the display screen 11 is (R1*S1+R2*S2+...+Rn*Sn)/( S1+ S2+...+Sn).

The pixels on the display screen 11 whose pixel values are not 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 each pixel position on the display screen 11 are determined. Since the pixels whose pixel value is 0 are not displayed, only the pixels whose value is not 0 are combined into the target image 30 .

In this embodiment, the aforementioned method is used in combination with the characteristics that the irregular curved screen can display images from multiple angles, and the traffic image step image is displayed with the target image 30 that is closest to the ideal effect, so that the driver can continuously The image of the traffic warning sign with the best display effect was observed stably.

Because the foregoing method adopts a curved screen to display, different pixel positions on the display screen 11 have different distances from the driver, and the brightness observed by the driver is lower when the pixels are farther under the same brightness. There will be brightness distortion in the image. And after the vehicle position changes, the distance between the image and the driver has also changed. Although the aforementioned method makes the traffic warning sign image display with the most suitable size and angle, the brightness of the image cannot meet the requirements of the desired effect.

In this embodiment, the brightness of each pixel of the target image 30 is further adjusted,

The 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 also includes:

S30741: Obtain the reference distance dc;

As shown in FIG. 9, the reference distance dc may be the shortest distance between the display screen 11 and the virtual plane 40;

S30742: Determine the shortest distance di between each first pixel on the display screen 11 and the virtual plane 40 according to the projection relationship between the virtual plane 40 and the display screen 11;

S30743: Calculate the distance difference dr of each first pixel according to dc and di, where dr=dc-di;

S30744: Obtain the brightness adjustment coefficient k(dr) corresponding to each first pixel according to the distance difference dr of each first pixel;

The brightness adjustment coefficient k(dr) is a function about dr, which can be determined through experiments. During the experiment, set the sensor at the set position, move the light-emitting unit from the position dc away from the sensor along a straight line, and record the brightness of the light-emitting unit detected by the sensor when the light-emitting unit is in different positions. The brightness when the light-emitting unit is at the position of the sensor dc is taken as the initial brightness L0, and the brightness when the light-emitting unit is at a distance from the initial position di is Li, then k(dr)=Li/L0 when dr=di. The function curve of k(dr) is obtained by fitting the k(dr) values at different positions of the light-emitting unit.

S30745: Adjust the brightness of each pixel in the target image 30 according to the original brightness Lr of the first pixel and the corresponding brightness adjustment coefficient, Lz=k(dr)×Lr, where Lz is the adjusted brightness of the first pixel.

The original brightness Lr of the first pixel is the brightness of 30 pixels of the target image before adjustment. After the brightness of each pixel on the display screen 11 is adjusted by the aforementioned method, 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 also close to the best display effect.

Preferably, the location of the smart light pole in the step S1 includes beside the pedestrian crossing, next to the parking space, the parking lot area and the side of the bus stop; the display mode includes rolling screen display, fixed screen display and split screen display, and the The three display modes are relatively suitable for single-information multiple objects, single-information single-object and multi-information single-object respectively. For example, the object can be a person or a pet, and the information can include an appearance image for a single object. , all kinds of graphics and texts to draw attention to others, prompt information provided to the object, etc. In this way, for different groups of people next to the crosswalk, parking space, parking area and bus stop, the corresponding display screens of each smart light pole can provide different groups of people with a suitable display method and a good display interface. Targeted content improves the viewing comfort and convenience of users.

Preferably, the smart light pole further includes a monitoring device, which may be a smart camera with a communication function, and when the position of the smart light pole is obtained to be beside the pedestrian crossing, the method further includes step S4: obtaining traffic According to the signal of the indicator light, the monitoring equipment is controlled to take pictures and recognize people entering the crosswalk area, and generate corresponding image information as the display content according to the recognized people. As for urban traffic, the traffic conditions in the pedestrian crossing area are more complicated and casualties are prone to occur. Therefore, by setting up smart light poles beside the pedestrian crossing, and using monitoring equipment to photograph and identify people and then display them, it will help Let the relevant traffic participants know the relevant prompt information in time, so as to help pedestrians and vehicles pass through the crosswalk safely.

Specifically, the pedestrian crossing area includes a passing area and a waiting area, and the step S4 further includes: S41: When the traffic light signal is a red light corresponding to the prohibition of passing through the passing area, then control the person who runs the red light to perform manual inspection. Intelligent recognition, the artificial intelligence recognition includes face recognition and pet recognition, and the result of face recognition can be matched with ID card database, medical database and other public security and medical databases to obtain detailed identification information. When it is a human being, the human being is captured, and the image information includes a human face image and a warning image text used to remind the driver to wait; A warning reminder image to remind drivers and pedestrians to be careful; S42: Carry out artificial intelligence recognition on the characters in the waiting area. When the area is about to turn into a green light that allows passing through, the image information includes a warning image that reminds the driver to stop in advance. The warning image can be easily observed and alerted by the driver such as a red exclamation mark; When a delivery person is recognized by means of helmet, motorcycle trunk, etc., the image information includes a captured image of the delivery person's head and an alarm image to remind the driver to stop in advance and the delivery person not to pass by forcefully. The deliveryman ran a red light in a hurry and caused a traffic accident. Therefore, by providing an alarm prompt image, both the deliveryman and the driver can drive more cautiously, and by displaying the head image of the deliveryman, not only the face is not directly displayed, which protects privacy, but also enables The takeaway staff understand that their traffic behavior has been documented, which plays an early warning role.

Preferably, the smart light pole is divided into a plurality of parts, and each of the smart light poles includes a monitoring device, and when the position of the smart light pole of the first part is obtained next to the parking space, Arranging the second part of the smart light poles at intervals along a preset distance in front of the parking spaces in the lane extension direction, the method further includes step S5: the monitoring equipment of each of the first part of the smart light poles monitors the occupancy of at least one parking space and In the idle state, when the monitoring result is an occupied state, the parking space occupancy state information for the second part of the smart light pole is generated as the display content.
