Different image acquisition devices are arranged at different positions, the image acquisition devices can be cameras, and the images of pedestrians passing through the corresponding positions can be acquired through the image acquisition devices.

The invention provides a smart cloud service illumination display method suitable for text travel, as shown in fig. 2, comprising the following steps:

step S110, the cloud server determines a first projection lamp set at a first position, determines a first travel image set by the first projection lamp according to a position number of the first position, and randomly determines a travel image in the first travel image set as a first travel image.

The cloud server firstly determines a first projection lamp arranged at a first position, wherein the first position can be a garden park, a travel park and the like, the first projection lamp can be a spotlight with an image display function, and a first travel image set arranged on the first projection lamp is determined according to a position serial number of the first position. The invention can randomly determine a text travel image in the first text travel image set as the first text travel image. The first text travel image may be an image having landscape elements, historic elements, cultural elements. For example, the first location is a garden park, the image of the garden park at that time.

In a possible implementation manner of the technical solution provided by the present invention, as shown in fig. 3, step S110 includes:

step S1101, after the first projection lamp determines that the time for displaying the current travel chart is greater than or equal to a first preset time, an image display request is generated, and the first projection lamp sends the image display request and the first position where the image display request is located to the cloud server. The invention sets a first preset time, namely after the time for displaying the current travel chart is more than or equal to the first preset time, the next travel chart needs to be displayed, at the moment, the first projection lamp generates an image display request, and the first projection lamp sends the image display request and the first position where the image display request is located to the cloud server. The staff can set up corresponding first position, position serial number to every first projection lamp.

Step S1102, after receiving the image display request, the cloud server determines a first projection lamp set at the first position, and determines a first travel image set by the first projection lamp according to a position number of the first position, where each position number has a first travel image set corresponding to the position number. The cloud server can confirm the first text image set that first projection lamp set up according to the position sequence number of first position after receiving the image show request, and different first projection lamps may set up different first text image sets in advance, can include the first text image that a plurality of staff set up in the first text image set. The location number may be location 1, location 2, location 3, etc.

Step S1103, deleting the second text image displayed in the current text image from the first text image set, and randomly selecting one text image from the first text image set as the first text image. The invention can delete the second travel image displayed by the current travel image from the first travel image set, and the mode can ensure that the randomly selected next first travel image is asynchronous with the second travel image at the previous moment, thereby ensuring that the travel images displayed by the first projection lamp in the adjacent time quantum are different.

Step S120, determining a first image capturing device set at a first position, acquiring a first captured image set captured by the first image capturing device within a preset time period, and randomly determining a preset number of first captured images corresponding to the first travel image in the first captured image set. The method determines a corresponding first image acquisition device arranged at a first position, and acquires a first acquisition image set acquired by the first image acquisition device within a preset time period. The first image acquisition device acquires images of all people passing through the position of the first image acquisition device to obtain a corresponding first acquired image set, the first acquired images with the preset number corresponding to the first travel images can be randomly determined in the first acquired image set, the preset number can be 1, 2 and the like, and the preset number corresponding to each first travel image can be preset. For example, a first travel image may be fused with 1 first captured image, and the preset number may be 1, for example, a first travel image may be fused with 2 first captured images, and the preset number may be 2. The first captured image may be regarded as an image of a human body, i.e. an image having a face of a human body.

Step S130, recognizing the face contour in the first collected image to obtain a face subimage, performing binarization processing on the face subimage to obtain a first binarized image only with white pixel points and black pixel points, and performing asynchronous processing on the gray level of the black pixel points according to the part of the face corresponding to each black pixel point to obtain a first adjusted image. The invention can identify the face outline in the first collected image to obtain the face subimage, and in the actual application scene, different people can have different first collected images when passing through the corresponding first positions, so the invention can obtain the face subimages of different people after identifying the face outline in the first collected image. The face image binarization method based on the image matching can carry out binarization processing on the face sub-image to obtain a first binarized image only with white pixel points and black pixel points, and carry out primary processing on the image in such a way, so that the face part under different lighting conditions and different light conditions can be correspondingly identified and displayed. The black pixel points with different gray scales correspond to different parts of the human face. The invention can asynchronously process the gray levels of the black pixels according to the part of the face corresponding to each black pixel to obtain a first adjustment image. The gray scale may be 0 to 255 gray scales, and the gray scale values corresponding to different parts may be different, for example, the gray scale of an eye may be 0, the gray scale of an eyebrow may be 50, the gray scale of an ear may be 100, and the like.

In one possible implementation manner, the technical solution provided by the present invention, in step S130, includes:

the face contour in the first collected image is recognized based on OpeanCV to obtain a face subimage, the pixel value of each pixel point in the face subimage is obtained, the pixel points in a preset pixel interval are converted into black pixel points, the pixel points in a non-preset pixel interval are converted into white pixel points, and a first binary image is obtained. The face image acquisition method based on OpeanCV can identify the face contour in the first collected image to obtain the face subimage which can be regarded as the image corresponding to the face contour, and after the face subimage is obtained, the pixel value of each pixel point in the face subimage can be obtained, the pixel points in the preset pixel interval are converted into black pixel points, and the pixel points in the non-preset pixel interval are converted into white pixel points. For example, the eyes and eyebrows of a person may be black and white, the pixel values corresponding to the eyes and eyebrows at this time are the preset pixel intervals corresponding to black and white, the lips may be red and pink, and the pixel values corresponding to the lips at this time are the preset pixel intervals corresponding to red and pink. In an actual application scene, in order to identify the color of the face of the user, the face of the human body can be irradiated and supplemented with light.

Detecting each part in the face subimage based on a Haar cascade detector, wherein the part comprises any one or more of a face, eyes, a nose, a mouth and ears, and determining pixel points corresponding to each part in the face subimage to obtain a pixel point set corresponding to each part. The method can detect each part in the face subimage based on a Haar cascade detector, determine a plurality of parts in the face subimage, and then determine pixel points corresponding to each part in the face subimage to obtain a pixel point set corresponding to each part.

And carrying out asynchronous adjustment on the gray level of the corresponding pixel point according to the part corresponding to each pixel point set to obtain the adjusted pixel value of each pixel point set, and taking an image formed by the adjusted pixel value of each pixel point set as a first adjustment image. According to the technical scheme provided by the invention, the gray levels of the corresponding pixel points can be asynchronously adjusted for each part, so that each part has different gray levels in the display process. For example, the gray scale of the pixel value of the pixel point corresponding to the mouth may be adjusted to 60. By the method, the gray levels of all the pixel point sets can be asynchronously adjusted according to different positions, so that the adjusted pixel value of each pixel point set is obtained, and an image formed by the adjusted pixel values of each pixel point set is used as a first adjusted image.

In a possible embodiment, the asynchronously adjusting the gray level of the corresponding pixel point according to the corresponding portion of each pixel point set to obtain the adjusted pixel value of each pixel point set, and taking an image formed by the adjusted pixel value of each pixel point set as a first adjusted image includes:

and determining the gray coefficient value of the part corresponding to each pixel point set, and adjusting the gray of the corresponding pixel point according to the gray coefficient value to obtain the adjusted pixel value of each pixel point set. The invention determines the gray scale coefficient value of the part corresponding to each pixel point set, the gray scale coefficient value of the pixel point set corresponding to the face part can be 255, 240 and the like, and the gray scale coefficient value of the pixel point set corresponding to the ear part can be 230 and the like. Through the above manner, the invention can convert the gray value of the face image, and make different parts have different gray values, for example, the color of the ear is similar to the color of the face (face), then the gray values of the face and the face may be similar, the colors of the eyebrow and the eye are similar, and then the gray values of the eyebrow and the eye may be similar.

And taking the number of the pixels in the pixel set corresponding to the face as a first number, taking the number of the pixels in the pixel set corresponding to other parts except the face as a second number, and calculating according to the second number and the first number to obtain the pixel proportion of each part. The invention can count the number of the pixels in the pixel set corresponding to the face, count the number of the pixels in the pixel sets corresponding to other parts, and calculate according to the second number and the first number to obtain the pixel proportion of each part. The proportion of each part relative to the human face can be obtained through the pixel proportion.

If the pixel proportion of any part is judged to be larger than the preset maximum proportion or smaller than the preset minimum proportion, the number of the pixels in the pixel set corresponding to the corresponding part is adjusted to obtain an adjusted pixel set, and a first adjusted image is obtained according to the adjusted pixel set. The proportion of a part relative to the human face can be reflected through the pixel proportion, and an image formed by the corresponding organ and the face is more attractive in appearance in a certain gold proportion interval of a certain part, so that the pixel proportion of any part is compared with the preset maximum proportion or the preset minimum proportion, namely when any part is too large or too small, the pixel proportion of the corresponding part is larger than the preset maximum proportion or smaller than the preset minimum proportion. In order to make the user image and the travel image more attractive after being fused, the number of the pixels in the pixel set corresponding to the corresponding part is adjusted to obtain the adjusted pixel set, and the corresponding part is increased or decreased to obtain a first adjusted image.

In a possible embodiment, if it is determined that the pixel proportion of any one of the portions is greater than the preset maximum proportion or less than the preset minimum proportion, adjusting the number of pixels in the pixel set corresponding to the corresponding portion to obtain an adjusted pixel set, and obtaining a first adjusted image according to the adjusted pixel set, the method includes:

and if the pixel ratio of any part is judged to be larger than the preset maximum ratio, calculating according to the pixel ratio of the part and the preset maximum ratio to obtain a pixel point adjusting coefficient. At this time, the corresponding part is too large compared with the human face, so the pixel point adjustment coefficient can be obtained by calculating according to the pixel ratio of the part and the preset maximum ratio. If the pixel occupation ratio is larger than the preset maximum occupation ratio, the corresponding pixel point adjustment coefficient is larger.

And calculating according to the pixel point adjustment coefficients and the number of the pixel points in the pixel point set corresponding to the corresponding parts to obtain the increased and adjusted pixel point adjustment number, and deleting partial edge pixel points in the pixel point set according to the pixel point adjustment number to obtain the deleted and adjusted pixel point set. The invention can combine the pixel point adjusting coefficient and the number of the pixel points in the pixel point set corresponding to the corresponding part to carry out comprehensive calculation, determine to increase the adjusted pixel point adjusting number, if the pixel point adjusting coefficient is larger, the corresponding pixel point adjusting number is more, and the invention can delete part of the edge pixel points in the pixel point set more.

And determining edge pixel points in the pixel point set according to the position relation of all the pixel points in the pixel point set, and deleting all the edge pixel points in the pixel point set if the number of the edge pixel points is judged to be more than or equal to the pixel point adjustment number, so as to obtain the deleted and adjusted pixel point set. According to the technical scheme provided by the invention, the edge pixel points in the pixel point set can be determined according to the position relation of all the pixel points in the pixel point set, and when the number of the edge pixel points is more than or equal to the adjustment number of the pixel points, the adjustment number of the pixel points is relatively small, so that all the edge pixel points in the pixel point set only need to be deleted at the moment, and the pixel point set after deletion adjustment is obtained. In this way, it is possible to perform deletion adjustment on a portion with a small number of pixel point adjustments.

And if the number of the edge pixel points is judged to be smaller than the pixel point adjustment number, determining the ratio of the pixel point adjustment number to the edge pixel point number to obtain a first deletion layer value, and rounding the first deletion layer value. At this time, the number of edge pixel points needing to be adjusted is large, and only the outermost edge pixel points and the pixel points adjacent to the edge pixel points are deleted, so that calculation needs to be performed according to the ratio of the adjusted number of the pixel points to the number of the edge pixel points, and a first deletion layer value is obtained.

According to the invention, all edge pixel points in the pixel point set can be deleted, and through the method, the edge pixel points in the current pixel point set can be deleted. According to the invention, after the edge pixel points which are deleted once are deleted, the edge pixel points in the adjusted pixel point set are determined again, so that the determining times of the edge pixel points in the pixel point set are synchronous with the first deleting layer number, the corresponding pixel point set can gradually delete the edge pixel points which correspond to the outer part and the edge for many times, and the number of the pixel points in the pixel point set corresponding to the corresponding part is further reduced.

And if the pixel proportion of any part is judged to be smaller than the preset maximum proportion, calculating according to the pixel proportion of the part and the preset maximum proportion to obtain a pixel point adjusting coefficient. At this time, the corresponding part is too small compared with the human face, so the pixel point adjustment coefficient can be obtained by calculating according to the pixel ratio of the part and the preset minimum ratio. If the pixel occupation ratio is smaller than the preset maximum occupation ratio, the corresponding pixel point adjustment coefficient is larger.

Calculating according to the pixel point adjustment coefficients and the number of pixel points in the pixel point set corresponding to the corresponding parts to obtain the pixel point adjustment number increased and adjusted, locking partial edge pixel points in the pixel point set according to the pixel point adjustment number, and classifying other pixel points adjacent to the edge pixel points into the pixel point set to obtain the pixel point set increased and adjusted. According to the invention, other pixel points adjacent to the edge pixel point can be determined, and at the moment, the corresponding other pixel points can be regarded as facial pixel points. By the method, partial edge pixel points in the pixel point set can be locked by combining the adjustment quantity of the pixel points, so that the pixel points in the pixel point set are increased, and the corresponding parts are enlarged and adjusted to be larger relative to the face.

In a possible embodiment, the technical solution provided by the present invention calculates the number of pixels in a pixel set corresponding to the corresponding portion according to the pixel adjustment coefficient to obtain the adjustment number of pixels with reduced adjustment, locks some edge pixels in the pixel set according to the adjustment number of pixels, classifies other pixels adjacent to the edge pixels into the pixel set, and obtains an increased adjusted pixel set, including:

the adjustment number of pixels to increase the adjustment is calculated by the following formula,

wherein the content of the first and second substances,

in order to reduce the number of pixel point adjustments to be adjusted,

is as follows

is as follows

in the form of a first number of bits,

is composed of

The weight value of the corresponding position is set,

is a preset minimum occupancy ratio. By passing

Calculating to obtain the pixel ratio of each part, if

The smaller the adjustment is, the larger the adjustment number of the adjusted pixel points

The larger.

And determining edge pixel points in the pixel point set according to the position relation of all the pixel points in the pixel point set, and determining all the pixel points of the face adjacent to each edge pixel point as pixel points to be added. The invention can determine the edge pixel points by combining the position relations of all the pixel points in the pixel point set, and then determine the pixel points to be added according to the edge pixel points. By the mode, faces of pixel points adjacent to the corresponding parts can be converted into the corresponding parts, so that the corresponding parts and the faces have reasonable proportion, and the corresponding parts are more visually coordinated.

Counting the number of all the pixels to be increased to obtain a first increased number, and classifying all the pixels to be increased into the pixel point set if the first increased number is larger than or equal to the pixel point adjustment number. Under this kind of scene, the increase proportion of corresponding position is less this moment, only need at this moment according to corresponding marginal pixel point increase once corresponding wait to increase pixel can.

If the first increased number is smaller than the pixel point adjusting number, determining the ratio of the pixel point adjusting number to the number of the pixel points to be increased to obtain a first increased layer number, and rounding the first increased layer number;

classifying all the pixels to be increased into the pixel point set to obtain a first increased and increased pixel point set, and determining the edge pixel points and the pixels to be increased in the adjusted pixel point set again to synchronize the determination times of the edge pixel points in the pixel point set with the first increased layer number. Under this kind of scene, the increase proportion of corresponding position is great this moment, needs to increase corresponding pixel point of waiting to increase many times according to corresponding marginal pixel point this moment. After each time of adjusting the pixel points of the pixel point set, the edge pixel points in the pixel point set can be changed, so that the invention can determine different edge pixel points and pixel points to be added for many times. It should be noted that, at this time, the determined number of times of the edge pixel point is synchronized with the first added layer number, that is, the larger the first added layer number is, the larger the range of the corresponding portion is increased.

In a possible implementation manner, the technical scheme provided by the invention determines the edge pixel point through the following steps:

and acquiring the pixel value of the adjacent pixel point of each pixel point in the pixel point set, and if the pixel points in contact with the pixel points of other parts exist, determining the corresponding pixel points as edge pixel points. By the method, the edge pixel points in each part and the pixel point set can be rapidly determined.

And determining a plurality of second sub-pixel values respectively corresponding to the second pixel value intervals according to the pixel values of the black pixel points with different gray levels in the first adjustment image. According to the invention, the second sub-pixel values corresponding to the black pixel points with different gray levels are determined according to the pixel values of the black pixel points with different gray levels in the first adjustment image, for example, the gray level is 0, and the second sub-pixel values are dark black at the moment, so that the corresponding second pixel values can be dark green at the moment; when the gray scale is 50, the gray scale of the pixel point is not particularly black, so that the corresponding second pixel value can be green at the moment; when the gray scale is 100, the gray scale of the pixel is white, so that the corresponding second pixel value may be light green. By the mode, the corresponding colors of all parts have certain color difference, and the decomposition and the distinction of the face and all parts in the face are easy to distinguish. Through this kind of mode, can make the text travel image of different colour bottom plates, correspond the face image of corresponding colour for text travel image can not produce when fusing with face image and move in the same direction as the colour, difficult difference the wait the condition.

And S150, determining the size of a reserved image of an image reserved position in the first travel image, adjusting the size of the second adjusted image, and fusing the second adjusted image and the first travel image to obtain a second travel image. In an actual application scenario, the sizes of the reserved images and the number of the reserved images in different first travel images may be different, but the sizes of the second adjustment images are relatively fixed, so the size of the second adjustment image is adjusted according to the size of the reserved image, and after the size of the reserved image corresponds to the size of the second adjustment image, the second adjustment image and the first travel image are fused to obtain the second travel image.

In one possible implementation manner of the technical solution provided by the present invention, step S150 includes:

and comparing the size of the reserved image with the size of the second adjustment image to obtain a first adjustment proportion.

And adjusting the size of the second adjustment image based on the first adjustment proportion, and determining a central pixel point of the adjusted second adjustment image as a first reference point. The size of the second adjustment image is adjusted according to the first adjustment proportion, namely the second adjustment image is reduced by 20 inches to obtain a 10-inch second adjustment image, and after the second adjustment image is adjusted, the first reference point is determined in the second adjustment image.
