At present, in order to enable a user to comprehensively know the online commodities, a plurality of platforms providing online expense functions can set an online work set for the commodities such as nail art and hairdressing, the online work set intensively collects multi-azimuth photos of the front, the side, the back and the like of the works such as nail art and hairdressing, and the user can know the details of the corresponding commodities and the design content of the commodities by looking over the work sets corresponding to the commodities. However, the applicant recognizes that most of the works sets provided by the platform arrange the multi-directional photos according to a certain sequence to form a photo queue, so that the user needs to actively turn pages in the works set transversely and smoothly to see all detailed pictures of the commodity, the operation requirement on the user is high, and some users do not want to browse the works sets, so that the browsing frequency of the detailed pictures of the commodity is low. Moreover, most of the pictures with concentrated works are shot by the merchants of stores at random at selected angles, so that the shooting capability is limited, the pictures are not standard enough, the problems of incomplete shooting angles of the works, missing of shooting details and the like are easily caused, and the usability of the pictures is poor. Therefore, the application provides a picture generation method, when a user requests to generate a three-dimensional effect picture of an object to be displayed, data acquisition is carried out on the object to be displayed in a plurality of preset positions, a plurality of three-dimensional data of the object to be displayed in the plurality of preset positions are obtained, a virtual effect model of the object to be displayed is constructed based on the plurality of three-dimensional data, a three-dimensional effect picture comprising the virtual effect model is generated, the three-dimensional effect picture is added to an object detail page of the object to be displayed for displaying, the three-dimensional data acquired in the plurality of preset positions are synthesized, the three-dimensional effect picture comprising the three-dimensional virtual effect model is generated for the object to be displayed, the effect of the object to be displayed is restored in a three-dimensional surrounding mode, the representation form of the object to be displayed is enriched, and the usability of the picture is improved.
The platform is provided with a picture generation inlet, when the platform detects that the picture generation inlet is triggered, a picture generation request of a user is determined to be received, data acquisition is carried out on an object to be displayed in a plurality of preset directions, and a plurality of three-dimensional data of the object to be displayed in the plurality of preset directions are obtained. The platform can be a platform which provides wired consuming functions for the outside, or can also be a platform which provides social services and can display entity objects, and the type of the platform is not limited in the application. Responding to a picture generation request, calling a laser radar component and an image acquisition component by a platform, acquiring basic parameters of an object to be displayed in a preset position based on the laser radar component configured on a terminal and image data of the object to be displayed in the preset position based on the image acquisition component configured on the terminal, and taking the acquired basic parameters and the image data in multiple directions as multiple three-dimensional data of the object to be displayed in multiple preset positions. Therefore, the three-dimensional data not only can embody the outline of the object to be displayed in the corresponding preset position, such as height, length and the like, but also can embody the color, pattern and the like of the object to be displayed in the corresponding preset position.
Specifically, the LiDAR component is a component with a LiDAR scanning function, such as a LiDAR (optical radar) component, configured on a mobile handheld terminal used when a user requests the platform to generate a picture, so that when the user operates in the terminal to request the terminal to generate the picture, the LiDAR component configured on the terminal is called to enable the LiDAR component to be turned on. The LiDAR component emits a beam of pulse laser to the object to be displayed, and measures basic parameters such as height, width and outline of the object to be displayed. The image acquisition component is a component with a shooting function of the terminal, such as a camera, and the platform can control the terminal to start the laser radar component and the image acquisition component through an instruction under the condition that a user allows the component to be accessed, so that the laser radar component and the image acquisition component can be scheduled. In addition, it should be noted that the content described above is described by taking the LiDAR component as an example, and in the process of practical application, if the LiDAR component is not configured at the terminal, the object to be displayed and the environment where the object to be displayed is located may also be understood based on the RealSense (real sensing technology) component configured at the terminal, and the RealSense component is used to perform interactive learning with the environment and the object to be displayed, so as to obtain the basic parameters of the object to be displayed. Or, the object to be displayed may be depicted based on a 3D (3 Dimensions) function of a primesencompine (short range motion sensing camera) component configured in the terminal, so as to obtain basic parameters of the object to be displayed. Or, the object to be displayed can be subjected to three-dimensional modeling in real time based on Project Tango (component for realizing three-dimensional modeling) configured by the terminal. It should be noted that, because the Project Tango is capable of real-time modeling, the 3D model established by the Project Tango can be directly used as the virtual effect model of the object to be displayed, and no reconstruction is needed. The type of the component used for data acquisition of the terminal is not specifically limited.
And then, in order to enable the collected three-dimensional data of the object to be displayed in a plurality of preset directions to be comprehensive and accord with the standard, the platform displays a preset contour range at the front end provided for the user, and the preset contour range is used for restricting the shooting range of the user. Taking the object to be displayed as the hair style as an example, the preset contour range may be a range from the set head to the upper half of the body, and is displayed in the center of the screen of the user terminal when the preset contour range is displayed, as shown in fig. 2B in particular, so that the user can photograph the hair style according to the specification.
And because need treat in a plurality of preset positions and show the object and carry out data acquisition in this application, the user will hold the terminal and treat that the show object shoots in the position of difference, in order to make the user know that need shoot at which position at present, the platform can adopt and treat the position of gathering and mark the preset profile scope when showing the preset profile scope, should treat that the position of gathering is any preset position in a plurality of preset positions to the user treats the show object in treating the position of gathering and carries out data acquisition. For example, a "front side" may be displayed directly above the preset outline range so that the user is currently going to the front side of the object to be displayed for data acquisition by the platform. It should be noted that, in the present application, a plurality of preset orientations are involved, and in order to make the user clearly acquire the progress, a sequence may be set for the plurality of preset orientations, a queue of the preset orientations is formed in sequence, and the queue is displayed right above the preset outline range. Further, the current orientation to be collected is highlighted in the queue in a color font, a large font and a label mode, so that the user knows which orientation data is currently collected, specifically, as shown in fig. 2B, a queue of "front → side → back → finish" is generated, when the user is required to collect front data, the font size of the "front" in the queue is increased, the "front" is highlighted, and the user is reminded by a character such as "please scan the front" below the preset outline range. It should be noted that the preset orientations of the front side, the side, and the back side and the sequence of the three are only an example, and in practical application, the preset orientations may be further refined into the preset orientations such as the left side, the right side, and the like.
After the platform displays the preset contour range and marks the preset contour range by adopting the position to be collected, data collection can be started for the object to be displayed, which is arranged in the preset contour range by the user. Because the laser radar component and the image acquisition component are simultaneously called by the platform, on one hand, the platform can transmit detection signals to the object to be displayed in the preset contour range based on the laser radar component, and basic parameters of the object to be displayed in the direction to be acquired are obtained. The basic parameters specifically include an object contour and an object size, and specifically can receive an echo signal returned by a detection signal, wherein the echo signal is a signal returned after the detection signal hits an object to be displayed. Then, since the probe signal is subjected to energy consumption when hitting an obstacle, an energy difference exists between the returned echo signal and the probe signal, and information related to the object to be displayed, such as the posture, the shape, the height, the width and the like of the object, can be obtained by calculating the energy difference, the platform processes the probe signal and the echo signal, compares the probe signal with the echo signal, and outputs the object outline and the object size of the object to be displayed as basic parameters of the object to be displayed in the to-be-acquired orientation according to the energy difference between the probe signal and the echo signal, so that a virtual effect model which is the same as the shape and the posture of the object to be displayed is established based on the basic parameters.
On the other hand, the platform can be based on the image acquisition subassembly and carry out image acquisition to the object of waiting to show that places in the scope of presetting the profile, obtain the image data of the object of waiting to show in waiting to gather the position. Specifically, a picture of the object to be displayed in the to-be-collected position may be taken as image data of the object to be displayed in the to-be-collected position, which is not specifically limited in the present application.
After basic parameters and image data of the object to be displayed in the position to be acquired are acquired based on the laser radar component and the image acquisition component, the platform takes the basic parameters and the image data as three-dimensional data of the object to be displayed in the position to be acquired, and data acquisition in the direction to be acquired is completed. And then, the platform selects a new position to be acquired from other preset positions, the data acquisition process is executed again, and the three-dimensional data of the object to be displayed in the new position to be acquired is acquired until all the preset positions are traversed to obtain a plurality of three-dimensional data, wherein the other preset positions are the preset positions except the position to be acquired in the preset positions.
It should be noted that, in order to restrict the shooting range of the user, the preset contour range may be displayed at the front end, and in order to correct the user in time, when considering that some users may sometimes acquire three-dimensional data, an object to be displayed may exceed the preset contour range, an object correction reminder may be generated when the object to be displayed exceeds the preset contour range, and the object correction reminder may be displayed. Specifically, the outline of the object to be displayed can be identified when the object to be displayed does not exceed the preset outline range, but the identified outline is broken when the object to be displayed exceeds the preset outline range, and the outline cannot be identified at some positions, so that whether the object to be displayed exceeds the preset outline range can be determined according to whether the object outline is broken or not. That is, if the contour of the object output according to the energy difference between the detection signal and the echo signal is broken, it is determined that the object to be displayed exceeds the preset contour range, and therefore, an object correction prompt is generated and displayed. The display mode of the object correction reminder is divided into two modes, one mode is text display, a prompt including a file such as 'beyond outline' is generated and displayed in a screen of the terminal, the other mode is voice display, the file such as 'beyond outline' is broadcasted in a voice mode, the display mode of the object correction reminder can be any one of the two modes, and the object correction reminder is not specifically limited in the application.
202. And constructing a virtual effect model of the object to be displayed based on the plurality of three-dimensional data.
In the embodiment of the application, after the plurality of three-dimensional data of the object to be displayed are acquired at the plurality of preset positions, the platform constructs a virtual effect model of the object to be displayed based on the plurality of three-dimensional data, so that 360-degree surrounding three-dimensional display of the object to be displayed on the terminal is realized.
When the virtual effect model is constructed, firstly, the platform acquires a plurality of basic parameters included by a plurality of three-dimensional data, and because the basic parameters indicate the outline, the posture, the shape and the like of the object to be displayed, the platform can perform wiring according to the plurality of basic parameters, and then an initial virtual model with the consistent posture, the shape and the like of the object to be displayed is constructed in a virtual space based on lines. Then, because the initial virtual model is only a line model in the virtual space and does not fill any relevant content such as color, material and the like, and the image data in the three-dimensional data just records the color, material and the like of the object to be displayed in each preset orientation, the platform reads the RGB (Red Green Blue, Red Green Blue channel) values of the plurality of image data included in the plurality of three-dimensional data, and fills the RGB values of the plurality of image data to the initial virtual model according to the preset orientations corresponding to the plurality of image data, so as to obtain the virtual effect model.
It should be noted that the process of generating the virtual effect model described above is actually a process of rendering a plurality of acquired three-dimensional data, and some model rendering components can directly render data acquired by the laser radar component and the image acquisition component at present and output a virtual effect model of an object to be displayed.
203. A three-dimensional effect picture including a virtual effect model is generated.
In the embodiment of the application, after the virtual effect model is generated, because the virtual effect model needs to be displayed for the user reference, in order to make the virtual effect model more beautiful, the platform adds some background elements to the virtual effect model, and generates a three-dimensional effect picture including the virtual effect model.
Specifically, the platform can acquire data of an object background of an object to be displayed in a plurality of preset orientations to generate an original background picture, and add the virtual effect model to the original background picture to obtain a three-dimensional effect picture, that is, a scene background of a scene where the current object to be displayed is used as a background to generate the three-dimensional effect picture, so that the reality sense of the three-dimensional effect picture is increased. Or, the platform may also set a default filling color, such as white, black, and the like, obtain the default filling color, generate a background base map filled with the default filling color, and add the virtual effect model to the background base map to obtain the three-dimensional effect picture. That is, the virtual effect model is displayed on the white background picture and the black background picture to generate the three-dimensional effect picture, so that the artistic sense of the three-dimensional effect picture is enhanced.
In the process of practical application, considering that a user may not be satisfied with the generated three-dimensional effect picture, and needs to regenerate, or wants to adjust the position or angle of the virtual effect model in the three-dimensional effect picture, the platform displays the three-dimensional effect picture, so that the user can see the result generated by the picture, and the user can conveniently select whether to regenerate the picture, and provide the function of manually adjusting the three-dimensional effect picture for the user. Further, in response to receiving a picture adjustment request based on the three-dimensional effect picture, determining a trigger point of a trigger operation on the three-dimensional effect picture, and adjusting the position of the virtual effect model in the three-dimensional effect picture according to the moving direction of the trigger point. For example, if the moving direction of the trigger point indicates that the position of the virtual effect model is adjusted to the right, the position of the virtual effect model in the three-dimensional effect picture may be adjusted according to the distance that the trigger point moves to the right. It should be noted that, in practical application, the angle of the virtual effect model in the three-dimensional effect picture may also be adjusted, for example, if the user uses two fingers to trigger the three-dimensional effect picture, the platform determines two trigger points of the two fingers on the three-dimensional effect picture, and rotates the virtual effect model according to an angle formed between a connecting line between the two trigger points and a horizontal line or a vertical line.
Further, in response to receiving a picture generation request based on the three-dimensional effect picture, the platform determines that the user wants to regenerate the three-dimensional effect picture, and in order to record the generated three-dimensional effect picture, the platform associates the three-dimensional effect picture with the object to be displayed, caches the associated three-dimensional effect picture, and collects a plurality of three-dimensional data of the object to be displayed in a plurality of preset directions again to generate a new three-dimensional effect picture. It should be noted that, in order to avoid that a user caches a large number of three-dimensional effect pictures for a certain object to be displayed occupies a large cache space of the platform, a number threshold may be set in the platform, and the number of three-dimensional effect pictures that can be cached by each object to be displayed is limited by the number threshold, for example, a number of 5, 10, and the like may be set as the number threshold. In this way, when the platform detects that the number of the cached three-dimensional effect pictures associated with the object to be displayed reaches the number threshold, all the currently cached three-dimensional effect pictures associated with the object to be displayed are displayed for the user to preview in the plurality of three-dimensional effect pictures, so that the user can select one three-dimensional effect picture for subsequent display. Further, in response to the target three-dimensional effect picture in all the three-dimensional effect pictures being triggered, the platform determines the subsequent display of the target three-dimensional effect picture by the user, and therefore the target three-dimensional effect picture is added to the object detail page for display. It should be noted that, when the platform displays all three-dimensional effect pictures for the user to preview, a deletion entry may be provided, so that the user triggers the deletion entry to delete one or more three-dimensional effect pictures, or delete all three-dimensional effect pictures.
