All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without inventive step, are intended to be within the scope of the present disclosure.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the disclosure. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The embodiment of the disclosure provides a recommendation method of projected content, where an execution subject of the recommendation method of projected content may be a recommendation device of projected content provided in the embodiment of the disclosure, or an electronic device integrated with the recommendation device of projected content, where the recommendation device of projected content may be implemented in a hardware or software manner. The electronic device may be a server that can communicate with the projection device or a control terminal of the projection device. The control of the projection device may be achieved by a remote control or a user-interactive interface of the projection device.
Referring to fig. 1, fig. 1 is a first flowchart illustrating a recommendation method for projected content according to an embodiment of the disclosure. The specific process of the recommendation method for the projection content provided by the embodiment of the disclosure may be as follows:
101. an ambient image of a projection device is acquired.
In the embodiment of the disclosure, the projection device may establish a connection with the server. When the projection equipment starts the display function of the digital artwork, namely the digital image, the digital artwork can be downloaded from the server for display. The digital art works are mainly digital images, including two-dimensional digital images, such as images of art paintings like oil paintings and wash painting, or three-dimensional digital images, such as three-dimensional images of three-dimensional artworks like sculptures. But also other digital images that can be presented by means of a projection device.
The environment image in the embodiment of the present disclosure is an image obtained by shooting the surrounding environment where the projection apparatus is located. There are various ways of acquiring the environment image, and several of them are described below.
For example, in some embodiments, one or more cameras may be provided on the projection device. When the number of the cameras is multiple, the cameras can be arranged at different positions on the projection equipment so as to be used for shooting environment images in different directions. Or, a rotatable camera may be disposed on the projection device, and when capturing the environment image, the camera may be rotated to capture a plurality of environment images in different directions. When a user starts the display function of the digital image of the projection equipment, the projection equipment starts a camera to shoot the surrounding environment to obtain an environment image, and the environment image is uploaded to the server.
For another example, in another embodiment, the user may use a mobile terminal such as a mobile phone, a tablet PC, a smart wearable device, or a PC (Personal Computer) to establish a communication connection with the projection device, use the mobile terminal as a control terminal of the projection device, and then use a camera of the mobile terminal to capture an environment image of the surrounding environment, where the environment image of the surrounding environment may be captured from a plurality of different angles, and the captured environment image may be transmitted to the projection device, and the projection device may upload the environment image to the server. Or, in another embodiment, the mobile terminal may also establish a communication connection with the server, and upload the environment image to the server after the environment image is captured.
The environment image is a decoration style image capable of representing the current surrounding environment of the projection equipment. For example, if the usage scene of the projection device is home use, the user may capture a plurality of environment images in different directions of the space where the projection device is located when taking a picture, so as to more accurately identify the environment style.
The server may periodically perform the pushing of the digital image, for example, in some embodiments, before 101, the method further comprises: acquiring a digital image pushing period and a pushing time interval corresponding to the projection equipment; and when the pushing time interval is larger than or equal to the digital image pushing period, executing the step of acquiring the environment image of the projection equipment. In this embodiment, the server monitors the push time interval of the projection device in real time, and when the push time interval is greater than the digital image push period set by the projection device, that is, when the distance between the time point of last digital image push and the current time point is greater than the digital image push period set by the projection device, 101 is executed, for example, an upload prompt message of an environment image is sent to the projection device to prompt the projection device to shoot the latest environment image and upload the latest environment image to the server.
Alternatively, in another embodiment, the step of acquiring the environment image of the projection device is preceded by the method further comprising: receiving a digital image acquisition request sent by the projection equipment, wherein the projection equipment acquires a new environment image when detecting that the environment is changed, and triggers the digital image acquisition request based on the new environment image; and executing the step of acquiring the environment image of the projection equipment according to the digital image acquisition request.
In this embodiment, the projection device monitors the environment in real time, for example, the projection device may capture an environment image at regular time, determine whether the environment changes according to the similarity between the times of the two captured environment images, generate a digital image acquisition request based on the latest environment image when the change of the environment is detected, and send the image acquisition request to the server, and after receiving the image acquisition request, the server obtains the latest environment image according to the image acquisition request. Through the scheme, the server can timely push the digital graph matched with the style of the changed environment to the projection equipment when the environment where the projection equipment is located changes.
102. And analyzing the environment image to identify the environment style of the space where the projection equipment is located.
After the server acquires the environment image, the environment image can be analyzed to determine the environment style of the current environment of the projection equipment. For example, in some embodiments, the step of analyzing the environmental image to identify an environmental style of a space in which the projection device is located includes: and analyzing the environment image according to a preset classification model to obtain the environment style of the space where the projection equipment is located.
In this embodiment, at the server side, an image classification model is constructed in advance, for example, a convolutional neural network model for performing environment style recognition. The training process for this model may be as follows: various environment images with different styles are collected, and style labels are added to each environment image. Style labels may include the chinese traditional style, the european and american style, the southeast asian style, the african style, and so forth. The style labels can be set according to actual needs. The method comprises the steps of forming a sample base by the environment images carrying the style labels, training a pre-constructed convolutional neural network model by using the sample base to obtain an image classification model, storing the image classification model in a server as a preset classification model, and identifying the environment style of the environment images uploaded by each projection device.
And after receiving the environment image, the server preprocesses the environment image according to the size requirement of the input image of the preset classification model. And then, analyzing the preprocessed environment image through the preset classification model to obtain a corresponding style label, wherein the style label can represent the environment style of the space where the projection equipment is located.
103. And acquiring the digital image matched with the environment style as a candidate push digital image.
A digital image library may be constructed in the server, which stores digital images of various styles. And previously labeling style labels for each digital image. It will be appreciated that to achieve a style match of the digital image with the environment, the digital image and the environment image above use the same set of style labels to represent their styles.
After the environmental style of the environmental image is obtained, a digital image matching the environmental image style is determined from the digital image library according to the corresponding label. For example, determining a style label for each digital image in the digital image library; and screening out the digital images with the style labels matched with the environment style from the digital image library to serve as candidate push digital images. Each digital image stored in the digital image library has a corresponding style label, and digital images having the same style label as that of the environment image are screened out from all the digital images based on the style labels, for example, if the environment style of the current environment image is the traditional style of China, the digital images belonging to the traditional style of China can be screened out from all the digital images, and the digital images are used as candidate push digital images.
104. Analyzing the environment image based on the projection direction of the projection device to identify a presentation parameter of a projection surface of the projection device.
105. And determining the digital image to be pushed from the candidate pushed digital images according to the display parameters.
After the candidate pushed digital images are acquired, next, the digital images to be pushed are further screened from the candidate pushed digital images based on the projection surface of the projection equipment.
In the foregoing, the projection device acquires at least one frame of environment image and uploads the frame of environment image to the server. The projection device uploads the projection direction of the projection device to the server while uploading the environment image, the projection surface used by the projection device in the current environment can be determined according to the projection direction, and the projection surface can be a surface which can be used for displaying projection content such as a wall in the current environment. The server determines a target environment image including projection plane information from at least one frame of environment image according to the projection direction, and analyzes the projection plane according to the target environment image to obtain display parameters of the projection plane, for example, the display parameters include one or more of data of size, material, color, shape, whether there is a protrusion, whether there is a decoration, style of an ornament, and the like of the projection plane. And then selecting candidate digital images matched with the display parameters from the candidate pushed digital images as the digital images to be pushed.
When the display parameter matching is matched with the candidate pushed digital image, the matching can be carried out according to a method similar to the matching of the environment style. Collecting various possible projection surface conditions in advance, obtaining display parameters of the projection surfaces, and constructing a matching relation between the display parameters and the digital image, for example, the matching relation can be constructed through a neural network model. Specifically, training samples are collected, each training sample comprises a digital image and display parameters, labels of the training samples are matching degrees between the digital image and the display parameters, and a large number of training samples are collected to train a pre-constructed neural network model so as to determine model parameters. After the display parameters are obtained, when the matching degree of the display parameters and the candidate pushed digital images is evaluated, the matching degree can be calculated according to the display parameters, the candidate pushed digital images and the trained neural network model. And then screening out candidate pushed digital images with the matching degree larger than a preset threshold value from the candidate pushed digital images to serve as the digital images to be pushed.
106. And pushing the digital image to be pushed to the projection equipment.
And then, sending the image to be pushed to the projection equipment for the user to select and display. Because the number of digital images in the digital image library is large, the number of digital images matched with the environment image can be screened according to the style label of the environment image. Thus, in some embodiments, a partial transmission may be selected first, and if requested again by the projection device, the transmission may continue.
For example, in some embodiments, the step of pushing the digital image to be pushed to the projection device may include: and randomly selecting one or more digital images from the digital images to be pushed, and sending the one or more digital images to the projection equipment. In this embodiment, a certain number of digital images are randomly selected from the digital images to be pushed, and the selected digital images are sent to the projection device.
According to the scheme, the environment image of the space where the projection equipment is located can be collected at any time according to needs, even if the use space of the projection equipment is changed, a new environment image can be shot immediately, the shot environment image is sent to the server, the server identifies the environment style according to the environment image, then the digital image matched with the environment style is selected and sent to the projection equipment, and the projection equipment can directly perform projection display on the digital images.
In particular implementations, the present disclosure is not limited by the order of execution of the various steps described, and some steps may be performed in other orders or concurrently without conflict.
As can be seen from the above, the recommendation method for projection content provided by the embodiment of the disclosure may acquire an environment image of a projection device, analyze the environment image to identify an environment style of a space where the projection device is located, acquire a digital image matched with the environment style as a candidate push digital image, and analyze the environment image based on a projection direction of the projection device to identify a display parameter of a projection surface of the projection device; the method comprises the steps of determining the digital images to be pushed from the candidate pushed digital images according to the display parameters, pushing the digital images to be pushed to the projection equipment, wherein the style of the digital images pushed to the projection equipment is consistent with the style of the current environment of the projection equipment, and a user can perform projection display on the digital images matched with the environment style, so that the pushing mode of projection contents is enriched, and the display effect is improved.
Referring to fig. 2, fig. 2 is a second flow chart illustrating a recommendation method for projected content according to an embodiment of the present invention. The method comprises the following steps:
201. an ambient image of a projection device is acquired.
202. And analyzing the environment image to identify the environment style of the space where the projection equipment is located.
The environment image in the embodiment of the present disclosure is an image obtained by shooting the surrounding environment where the projection apparatus is located. A camera may be provided on the projection device. When the number of the cameras is multiple, the cameras can be arranged at different positions on the projection equipment and used for shooting environment images in different directions. Alternatively, the user may establish a communication connection with the projection device using a mobile terminal provided with a camera, such as a mobile phone, and use the mobile terminal as a control terminal of the projection device, and then shoot an environment image of the surrounding environment using the camera of the mobile terminal, where the environment image of the surrounding environment may be shot from a plurality of different angles, and the shot environment image may be transmitted to the projection device, and uploaded to the server by the projection device.
After the server acquires the environment image, the environment image can be analyzed to determine the environment style of the current environment of the projection equipment. For example, the environment image is analyzed according to a preset classification model, and the environment style of the space where the projection device is located is obtained. The preset classification model can be obtained by training a model constructed based on algorithms such as a convolutional neural network, a K nearest algorithm or a support vector machine through a pre-collected sample. The specific algorithm may be selected according to actual needs, and the embodiment of the present disclosure does not limit this.
203. And acquiring the current user information of the projection equipment.
In the embodiment, the pushing of the digital images is further carried out by combining the preference of the user for each digital image on the basis of the environment style.
If the user information has corresponding preference information, executing 204; if the user information does not have corresponding preference information, 205 is executed.
204. And acquiring the digital image matched with the environment style and the preference information as a candidate pushed digital image.
The server can build a digital image library, and the digital image library stores digital images of various styles. And previously labeling style labels for each digital image. It will be appreciated that to achieve a style match of the digital image with the environment, the digital image and the environment image above use the same set of style labels to represent their styles.
In addition, the server may further store the preference information of the user uploaded by each projection device. That is to say, when a user uses the projection device, the user logs in the projection device through user information, after the projection device starts a display function of the digital image, in the using process of the function, the operation of the user for selecting the digital image can be recorded, the recorded related data and the user information are associated and then uploaded to the server, and the server analyzes the data to obtain preference information corresponding to the user information and stores the preference information and the user information as one of bases for pushing the subsequent digital image.
For example, in some embodiments, the method further comprises: receiving image evaluation information sent by projection equipment; acquiring an image to be evaluated, user information, and the grading and display duration of the image to be evaluated from the image evaluation information; and calculating a preference value of the image to be evaluated according to the score and the display duration, and storing the preference value, the user information and the image to be evaluated in a correlation manner.
In this embodiment, a user may score the digital image currently displayed in projection on the display interface through the control terminal, where the score represents a preference degree of the user for the digital image. And the user can switch the digital image displayed currently back and forth, and after the digital image to be displayed is selected, the projection equipment records the display time length of the digital image. And the projection equipment associates the recorded name, score and display duration of the digital image with the current user information and then sends the digital image to a server.
After receiving the information, the server can take the corresponding digital image as an image to be evaluated, and calculate the preference value of the image. For example, the server may convert the presentation duration into a score value, calculate the score value and the score according to a weighting algorithm to obtain a composite score, and represent the composite score as a preference value of the user for the digital image. And storing the preference value, the user information and the image to be evaluated in a correlation manner. During the weighting calculation, corresponding weight values can be given to the two scores according to requirements.
Based on the stored preference information, the server determines the current environment style and then selects a matching digital image from the digital image library in combination with the environment style and the preference information. In some embodiments, the step of obtaining digital images matching the environmental style and the preference information as candidate pushed digital images may comprise: screening out digital images matched with the environment style from the digital image library to serve as candidate digital images; and acquiring a plurality of digital images from the candidate digital images in the order of the preference values from high to low to serve as candidate push digital images.
In this embodiment, the environment style may be used as a first filtering dimension, all digital images matching the environment style are selected from the digital image library, then, for the selected images, digital images having preference values corresponding to the user information are selected, and a certain number of digital images are selected as candidate push digital images according to an order of preference values from high to low. For example, if 1000 digital images matching the environmental style are selected from the digital image library, and 50 digital images having the preference value corresponding to the user are selected, a certain number of digital images can be selected from the 50 digital images preferentially, and a certain number of digital images can be randomly selected from the other 950 digital images and pushed together to the projection device. Wherein, the image pushing quantity can be set according to actual needs.
Optionally, in some embodiments, after all the digital images matching the environmental style are selected from the digital image library, for the selected digital images, a digital image with a preference value corresponding to the user information is selected, and then similar image recognition is performed from the digital images without the preference value, and a digital image similar to the digital images with the preference value (or with a higher preference value) is selected as a part of the digital images to be pushed. For example, if 1000 digital images matching the environmental style are selected from the digital image library, and 50 digital images having the preference value corresponding to the user are selected, a certain number of digital images may be preferentially selected from the 50 digital images, and a certain number of digital images similar to the digital images having the higher preference value from the 50 digital images may be selected from the other 950 digital images and pushed together to the projection device.
205. And acquiring the digital image matched with the environment style as a candidate push digital image.
It will be appreciated that the matching of digital images may be done according to the environmental style only, if the user's preference information is not already stored in the server. For a specific matching manner, please refer to the above embodiments, which are not described herein again.
206. Analyzing the environment image based on the projection direction of the projection device to identify a presentation parameter of a projection surface of the projection device.
207. And determining the digital image to be pushed from the candidate pushed digital images according to the display parameters.
The projection device uploads the environment image and simultaneously uploads the projection direction of the projection device to the server, the projection surface used by the projection device in the current environment can be determined according to the projection direction, and the projection surface can be a surface which can be used for displaying projection content, such as a wall in the current environment. The server determines a target environment image containing projection plane information from at least one frame of environment image according to the projection direction, and analyzes the projection plane according to the target environment image to obtain display parameters of the projection plane, for example, the display parameters include one or more of data of size, material, color, shape, whether there is a protrusion, whether there is a decoration, style of the decoration, and the like of the projection plane. And then selecting candidate digital images matched with the display parameters from the candidate pushed digital images as the digital images to be pushed.
The projection surface belongs to a part of the using environment of the projection equipment, and the projection surface display parameters also belong to a part of the environment style and reflect the local style of the using environment. After further screening, the selected digital image to be pushed not only can be adapted to the current overall environment of the projection equipment, but also can be adapted to the local style of a specific projection surface, so that the image to be pushed matched with the environment can be selected by integrating the environment style and the projection surface display parameters.
208. And pushing the digital image to be pushed to the projection equipment.
Through the scheme, when the user uses the display function of the digital image for the first time, the server does not store the preference information corresponding to the user information, and the digital image can be pushed only by considering the environment style and the display parameters of the projection surface. After the user uses the function for a period of time, the server updates and stores preference information corresponding to the user information, and then the matched digital image is selected from the digital image library and pushed to the projection equipment by combining the environment style, the display parameters of the projection surface and the preference information of the user on the digital image.
As can be seen from the above, the recommendation method for projection content provided in the embodiment of the present invention combines the environment style of the environment where the projection device is located, the display parameter of the projection surface, and the preference information of the user on the digital image, selects the matched digital image from the digital image library and pushes the selected digital image to the projection device, so that the user can quickly select the digital image which is matched with the current environment style and meets the preference of the user from the pushed digital image, and the display effect is improved while the image selection efficiency is improved.
