Description

Technical Field

[0001] This disclosure relates to the field of computer technology, and in particular to an object display method, apparatus, device, and storage medium. Background Technology

[0002] Currently, when displaying target objects (such as vehicles) on electronic platforms, a 360-degree panoramic view of the target object is mainly achieved by constructing a 3D model of the target object. This method requires 3D modeling of target objects of different brands and models in advance. Furthermore, for some second-hand target objects with defects, even target objects of the same brand and type may have different locations of defects or different details of the object to be displayed. Therefore, it is necessary to perform 3D modeling of each target object in advance, which greatly increases the cost and difficulty of implementing object view display.

[0003] Meanwhile, when rotating the model to create a panoramic view of the target vehicle based on its 3D model, high computational resource consumption can cause the view to lag and become choppy, affecting not only computational performance but also the display effect. Summary of the Invention

[0004] This disclosure provides an object display method, apparatus, computer device, and storage medium to achieve effective view display of a target object.

[0005] In a first aspect, embodiments of this disclosure provide an object display method, the method comprising:

[0006] Triggering the entry into the view display mode of the target object, displaying an image frame of the target object; the image frame is an image frame in an image set, the image set includes multiple image frames corresponding to the target object, and each image frame corresponds to a different display angle range;

[0007] In response to a view rotation command in the current view rotation mode, the system determines the image frame to be displayed from the image set based on the current display angle range corresponding to the currently displayed image frame and the rotation information in the view rotation mode, and then displays the image frame to be displayed.

[0008] Secondly, embodiments of this disclosure also provide an object display device, the device comprising:

[0009] The first display module is used to trigger the view display mode of the target object and display an image frame of the target object; the image frame is an image frame in the image set, the image set includes multiple image frames corresponding to the target object, and each image frame corresponds to a different display angle range;

[0010] The second display module is used to respond to the view rotation command in the current view rotation mode, determine the image frame to be displayed from the image set based on the current display angle range corresponding to the current display image frame and the rotation information in the view rotation mode, and display the image frame to be displayed.

[0011] Thirdly, embodiments of this disclosure also provide a computer device, the computer device comprising:

[0012] One or more processors;

[0013] Storage device for storing one or more programs.

[0014] When the one or more programs are executed by the one or more processors, the one or more processors implement the object display method provided in any embodiment of this disclosure.

[0015] Fourthly, embodiments of this disclosure also provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the object display method provided in any embodiment of this disclosure.

[0016] The technical solution of this disclosure specifically discloses an object display method, apparatus, computer device, and storage medium. The method includes: triggering entry into a view display mode of a target object, and displaying an image frame of the target object; the image frame is an image frame in an image set, the image set including multiple image frames corresponding to the target object, and each image frame corresponding to a different display angle range; responding to a view rotation command in the current view rotation mode, determining an image frame to be displayed from the image set based on the current display angle range corresponding to the currently displayed image frame and the rotation information in the view rotation mode, and displaying the image frame to be displayed. The above technical solution pre-captures image frames of different display angle ranges from a 360-degree omnidirectional perspective for each target object to be displayed. Therefore, by displaying image frames in different display angle ranges, the 3D display effect using existing 3D models can be visually simulated. This technical solution eliminates the need to construct 3D models for different objects, greatly reducing the cost and difficulty of object view display, reducing the waste of computing resources, and effectively solving the problems of view display lag and unsmoothness. Meanwhile, in the object display implemented using the technical solution provided in this embodiment, the image frame to be displayed for the object can be determined according to the different rotation modes of the current view. That is, the corresponding image frame to be displayed is different when the rotation mode of the current view is different, thereby enriching the display form of the object display and reflecting the diversified display of the panoramic view of the object.

[0032] Figure 1 This is a flowchart illustrating an object display method provided in Embodiment 1 of this disclosure. This embodiment is applicable to situations where a target object is displayed in a 360-degree panoramic view or a partial range of angle values. The method can be executed by an object display device, which can be implemented by software and / or hardware and can be configured in a terminal and / or server to implement the object display method in this disclosure.

[0033] It should be noted that existing methods for displaying object views mostly rely on 3D object models. However, with the diversification of object brands and types, the cost of constructing 3D object models has increased significantly, especially for objects (products) involved in the secondhand market. Different secondhand products have different defects, requiring the construction of a 3D object model for each product, greatly increasing the difficulty of object display. Furthermore, existing object view displays primarily achieve this through the rotation of the object's 3D model, which requires significant computational resources and can lead to display stuttering and unresponsiveness, affecting the overall display effect.

[0034] This embodiment provides an object display method that can better solve the problems caused by existing object display methods.

[0035] like Figure 1 As shown, the object display method provided in this embodiment may specifically include:

[0036] S101. Trigger the entry into the view display mode of the target object and display an image frame of the target object; the image frame is an image frame in the image set, the image set includes multiple image frames corresponding to the target object, and each image frame corresponds to a different display angle range.

[0037] In this embodiment, one application scenario for the view display can be an electronic trading platform for buying and selling product objects. The target object can be any product object selected by the consumer or browser who wants to know more about its details. Taking the application scenario of buying and selling a target vehicle as an example, the target object can be a target vehicle for which more details are desired. This embodiment can realize the view display of the target object on the electronic trading platform involving the target vehicle. The following description of this embodiment mainly uses the target vehicle as the target object, but it is not limited to the target vehicle.

[0038] In this embodiment, consumers or browsers can select a target vehicle on the e-commerce platform from which they wish to learn more about its details, and then enter the target vehicle's details display interface. When there is a need to view the target vehicle, the associated functions of the view display mode can be triggered. This step can be achieved by receiving a trigger command to enter the target vehicle's view display mode.

[0039] The key to displaying the target vehicle in this embodiment lies in capturing a 360-degree panoramic image of the target vehicle. Therefore, before implementing the method provided in this embodiment, it is necessary to capture images of the target vehicle from all 360 degrees. For example, in one implementation, the 360 ​​degrees can be divided into multiple display angle intervals (e.g., dividing the 360 ​​degrees into 10-degree intervals results in 36 different display angle intervals). Then, in a given shooting container, images of the target vehicle are taken from different display angle intervals. These images can include the vehicle's exterior, the vehicle with its doors open, interior details, and any imperfections. Essentially, an image frame can be captured from each display angle interval using different shooting methods. This embodiment can form corresponding image sets based on different shooting methods, and these image sets include image frames of the target object from different display angle intervals under each shooting method.

[0040] The view display can be a panoramic view or a partial view from a panoramic angle. A panoramic view can be considered a 360-degree panorama, which can correspond to a circle in a spatial orientation. This circle can be divided into multiple viewing angle intervals, each with the same angle. In this embodiment, the different viewing angle intervals within the panoramic view can be considered as viewing angle intervals formed by dividing the 360-degree panorama. To facilitate effective display of the target object, this embodiment pre-captures 360-degree panoramic image frames of the target object.

[0041] After entering the view display mode, this embodiment can load image frames captured under different display angle ranges through this step, and display the image frames of one of the display angle ranges. The displayed image frames can be the image frames corresponding to the display angle range under a certain shooting mode. In this embodiment, the image set under the whole vehicle appearance shooting mode is loaded first. The image set includes image frames under the whole vehicle appearance shooting mode under different display angle ranges, and the image frames of a certain display angle range are displayed.

[0042] It is known that in the implementation of image frame display, the loading operation performed in this step may take a period of time. During the loading operation, the loading animation can be displayed in the display area of ​​the screen interface, or the image frame of the target vehicle at a set display angle range can be displayed at a low resolution.

[0043] This embodiment can detect and determine the completion of loading during the loading operation, and can enter the execution logic for displaying image frames once loading is detected. It should be understood that displaying the view of the target vehicle is equivalent to displaying the image frames corresponding to the target vehicle in different display angle ranges in sequence. At the visualization level, this display effect can be described as presenting a target vehicle rotating in space, so as to realize the view display of the target vehicle corresponding to the image frames from different perspectives.

[0044] S102. In response to the view rotation command in the current view rotation mode, based on the current display angle range corresponding to the currently displayed image frame and the rotation information in the view rotation mode, determine the image frame to be displayed from the image set and display the image frame to be displayed.

[0045] In this embodiment, the view display of the target vehicle can be abstracted as a view rotation display of the target vehicle. This view rotation display can be further specified as the sequential display of image frames corresponding to different display angle ranges. To implement the execution logic of this view rotation display, rotation control of the view rotation needs to be executed. In this embodiment, the different control methods of this rotation control can be determined by the current view rotation mode.

[0046] In this embodiment, the view rotation command in the current view rotation mode can be understood as an instruction initiated by controlling the content displayed in the view to change from the currently displayed image frame to the next image frame to be displayed. In the automatic view rotation mode, the view rotation command can be formed by the rotation characteristics of the automatic view rotation, such as continuously generating view rotation commands according to a set period. In the passive view rotation mode, the view rotation command can be formed by the passive sliding control of the displayed target object, such as receiving the sliding control of the target object in the currently displayed image frame to trigger the generation of the next view rotation command.

[0047] This step responds to view rotation commands generated in the current view rotation mode, determines the corresponding image frame to be displayed, and then displays the image frame. Specifically, the current view rotation mode can be automatic view rotation mode or passive view rotation mode, with different modes entered through corresponding triggers.

[0048] In this embodiment, different settings can be made for the rotation form in different view rotation modes. For example, in automatic view rotation mode, the view can be set to rotate at a constant speed, while in passive view rotation mode, it can be set to rotate according to the rotation speed passively controlled by a third party. The third-party passive control can be either touch-slide control of the target object displayed in the screen display area of ​​the view display mode, or cursor-slide control of the target object displayed in the screen display area of ​​the view display mode. Different view rotation modes correspond to different rotation information, which can be understood as information characterizing the rotation features of the view rotation mode. The settings for the different view rotation modes mentioned above can be considered as part of the rotation information.

[0049] In this embodiment, the currently displayed image frame can be considered as the image frame presented when displaying the target object before responding to the view rotation command at the execution time. By establishing the association between image frames and display angle ranges, the current display angle range corresponding to the currently displayed image frame can be obtained. This step can first determine the angle range to be displayed based on the current display range and the rotation information in the current view rotation mode, and then display the image frame corresponding to the determined angle range in the image set as the image frame to be displayed. The angle range to be displayed can be understood as the angle range to which the target object needs to be displayed after responding to the view rotation command.

[0050] Following the above description, the determination of the angle range to be displayed can be considered to involve different logics depending on the current view rotation mode. Specifically, different angle ranges to be displayed can be determined based on the different rotation information corresponding to different view rotation modes. For example, in the automatic view rotation mode, when the rotation information is a uniform rotation at a first speed, the determined angle range can be the first one to be displayed. In the passive view rotation mode, the second speed and the sliding speed under third-party passive control can be used as rotation information, and the second angle range to be displayed in the passive view rotation mode can be determined based on this rotation information. Since the second speed is faster when sliding is faster and slower when sliding is slower, the rotation information is different in different view rotation modes, therefore the determined second angle range to be displayed is different from the first angle range to be displayed.

[0051] In this embodiment, one way to determine the angle range to be displayed in the current view rotation mode can be described as follows: under a constant rotation speed, combined with the current display angle range, determine how many angles the target vehicle has rotated in the view display mode, and combined with the rotation duration determined when the display angle range is defined, the angle range to be displayed corresponding to the view rotation response execution time can be determined.

[0052] In this embodiment, another way to determine the current display angle range in the current view rotation mode can be described as follows: In the case of passive rotation based on third-party control, the sliding distance of the sliding trajectory formed from the time of third-party passive control rotation to the time of response execution can be monitored. The sliding distance can be determined by mapping relationship to determine how many angle values ​​have been rotated in the view display implementation. Then, combined with the interval angle value determined when the display angle range is defined, the display angle range corresponding to the time of response execution can be determined.

[0053] Following the above description, in the case of passive rotation based on third-party control, a buffered rotation can also be considered after the passive rotation stops under third-party control. In this case, a buffer parameter for deceleration buffering can be determined based on the sliding rate when the passive rotation stops under third-party control. Then, based on the sliding rate, the buffer parameter, and the interval from the moment the passive rotation stops under third-party control to the moment of response execution, a buffered rotation angle can be determined. After knowing the interval angle value corresponding to each display angle interval, the display angle interval on which the target vehicle is displayed through the display image frame can be determined by the buffered rotation angle.

[0054] It should be noted that the method provided in this embodiment can be equivalent to a loop execution logic. That is, as the execution logic is executed at each execution time, the operation of determining the angle range to be displayed and the corresponding image frame to be displayed will be performed, and the operation of displaying the image frame to be displayed will be performed.

[0055] This embodiment provides an object display method that pre-captures image frames from different viewing angles within a 360-degree omnidirectional range for each target object to be displayed. By displaying these image frames from different viewing angles, the method visually simulates the 3D display effect of existing 3D models. This technical solution eliminates the need to construct 3D models for each object, significantly reducing the cost and difficulty of object display and minimizing the waste of computing resources. It effectively solves the problems of lag and stuttering in view display. Furthermore, in the object display implemented using this embodiment, the required image frames for display can be determined based on the current view rotation mode. That is, different view rotation modes correspond to different image frames, thus enriching the display formats and showcasing diverse panoramic views of objects.

[0056] As a first optional embodiment of this example, based on the above embodiments, an implementation method is provided for determining the image frame to be displayed in the current view rotation mode. Specifically, determining the image frame to be displayed from the image set based on the current display angle range corresponding to the currently displayed image frame and the rotation information corresponding to the view rotation mode may include:

[0057] a1) When the view rotation mode is automatic rotation mode, determine the angle range to be displayed based on the current display angle range and the uniform rotation rate corresponding to the automatic rotation mode.

[0058] In this embodiment, the timing of entering the view rotation mode can be achieved by receiving a view rotation mode trigger operation, or by detecting a view rotation mode trigger condition. Preferably, it can be by receiving a trigger operation for the automatic view rotation function; or, if no other view rotation mode is detected within a set interval. This embodiment can detect which view rotation mode is currently in after entering the view display mode, and when it is determined that the current view rotation mode is automatic, the logical operation of this step can be executed to determine the angle range to be displayed.

[0059] The automatic view rotation function can be a functional control displayed on the screen interface. If no other view rotation mode is detected within a set interval, this other view rotation mode can be a passive view rotation mode. In this embodiment, if no passive view rotation mode is detected within the set interval, the system enters the automatic view rotation mode. This other view rotation mode can also be a specific view mode available in the execution of the method in this embodiment, such as a view of a vehicle with its door open, or a view of an image in a magnified area. Specific view modes can also be triggered according to corresponding triggering conditions. This embodiment can also enter the automatic view rotation mode when no specific view mode is detected within the set interval.

[0060] In this embodiment, the automatic view rotation mode can be understood as a target vehicle view display mode that can control the view rotation according to the set rotation control logic without the intervention of rotation control information generated by an external third party. The set rotation control logic can limit the rotation speed of the view, such as limiting the view to rotate at a given speed.

[0061] Following the above description, the target vehicle view display achieved in this mode can be described as follows: after acquiring image frames from different display angle ranges, the image frames corresponding to different display angle ranges are presented on the screen interface in a certain order and at a certain rotation speed to simulate the rotation view of the target vehicle in three-dimensional space. The uniform rotation speed can be considered as the switching speed of image frames from one display angle range to the next. That is, the faster the uniform rotation speed, the faster the switching speed of image frames corresponding to different display angle ranges.

[0062] In this embodiment, the constant rotation speed used in the automatic view rotation mode can be considered a rotation characteristic under automatic rotation. Based on constant rotation, it can be assumed that the time taken for the image frame corresponding to one display angle range to switch to the image frame corresponding to the next display angle range on the screen interface is the same.

[0063] This embodiment can determine the angle range to be displayed at the time of response execution by using a uniform rotation rate in automatic view rotation mode. The uniform rotation rate can be characterized by the duration of rotation of the image frame displayed on the screen. Therefore, the display angle range at the time of response execution either remains unchanged without adjustment until the required interval is reached, or it adjusts due to the completion of the rotation duration, thus determining a new angle range to be displayed.

[0064] As one implementation method, this step compares the rotation interval duration associated with the uniform rotation rate with the rotation duration to determine whether the response execution time should maintain the existing current display angle range or adjust to a new display angle range. The current display angle range that remains unchanged or the new display angle range to which it needs to rotate is recorded as the display angle range determined in this step.

[0065] b1) When the view rotation mode is passive rotation mode, determine the angle range to be displayed based on the current display angle range and the corresponding rotation stage in the passive rotation mode.

[0066] In this embodiment, the view can be determined to be in passive rotation mode when a third-party sliding control is detected in the display area where image frames are displayed. Alternatively, the view can enter passive rotation mode upon receiving a trigger condition for passive rotation (such as the passive rotation control on the screen being triggered). The view can freely switch between automatic rotation mode and passive rotation mode based on the detection of the corresponding trigger condition.

[0067] This implementation can determine the angle range to be displayed by executing this step and subsequent related logical operations when it is determined that the current view is in passive rotation mode. The third-party sliding control can be generated by touching and sliding within the display area, or by controlling a physical input device such as a mouse to be pressed and controlling its corresponding cursor to slide within the display area.

[0068] It should be noted that when displaying the view of the target vehicle through third-party sliding control, it is impossible to guarantee that the passive control will always be in a constant speed mode. Furthermore, if the rotation of the panoramic view is stopped immediately when the third-party sliding control stops, it will also affect the view display effect. Therefore, this embodiment considers maintaining the view rotation for a period of time after the third-party sliding control stops, using this view rotation as a buffer to present the effect of gradually stopping the view rotation.

[0069] In this embodiment, the rotation stage corresponding to the passive rotation mode can be considered as one type of rotation information possessed in the passive rotation mode. After determining that the current view is in passive rotation mode, this step further determines which specific stage of the view passive rotation mode it is currently in. In this embodiment, the view rotation presented when the third-party sliding control is applied to the display area can be recorded as the third-party sliding control execution stage, and the stage in which the view rotation continues after the third-party sliding control stops can be recorded as the buffer rotation stage. In this embodiment, the execution logic for determining the image frame to be displayed differs when the view passive rotation mode is in different rotation stages.

[0070] Specifically, the angle range to be displayed can be determined based on the sliding distance of the sliding trajectory formed by the third-party sliding control during the rotation phase. Alternatively, the angle range can be determined based on the sliding rate when the third-party sliding control stops during the buffer rotation phase after the rotation phase has stopped.

[0071] c1) Determine the image frame corresponding to the angle range to be displayed from the image set as the image frame to be displayed.

[0072] As we know, the image set contains image frames corresponding to different display angle ranges. This step can determine the image frame corresponding to the display angle range by searching the image set, and then record it as the image frame to be displayed.

[0073] The technical solution described in this embodiment provides an implementation for determining the angle range to be displayed in both automatic and passive view rotation modes. By determining the angle range to be displayed, it is possible to effectively determine which aspect of the target vehicle should be displayed on the screen at the appropriate time to ensure the effective display of the target vehicle view. This embodiment provides an effective way to determine the basic data required for the execution logic of the view display.

[0074] Based on this first optional embodiment, determining the display angle range according to the current display angle range and the uniform rotation rate corresponding to the automatic rotation mode can be further specified as the following steps:

[0075] a11) Determine the entry time of the current display angle interval, and determine the rotation duration of the current display angle interval based on the uniform rotation rate.

[0076] In this embodiment, to determine the angle range to be displayed at the time of response execution, this step can be used to determine the entry time of the current display angle range. This step can also determine the rotation duration associated with automatic rotation in each display angle range based on the uniform rotation rate.

[0077] The rotation duration can be considered as being related to the uniform rotation speed set in the automatic view rotation mode, and is used to characterize the duration of the image frame on the screen interface switching from the image frame corresponding to one display angle range to the image frame corresponding to the next display angle range.

[0078] a12) The time interval between the response execution time and the entry time of the interval is determined as the rotation interval duration.

[0079] a13) If the rotation interval duration is less than the rotation duration, then the current display angle range is kept as the display angle range.

[0080] In this embodiment, when the rotation interval duration determined above is less than the rotation duration, it can be considered that the response execution time is still within the current display angle range. Thus, the current display angle range can be kept unchanged and still be used as the display angle range for the response execution time.

[0081] a14) If the rotation interval duration reaches the rotation duration, then the angle range to be displayed is determined according to the interval angle value of the current display angle range and the set rotation step size.

[0082] In this embodiment, when the rotation interval time determined above is less than the set interval threshold, it can be considered that the response execution time has reached the condition to trigger the entry into the next display angle interval. Thus, this step is used to determine a new display angle interval as the display angle interval.

[0083] It is understood that when dividing the 360-degree panorama into display angle intervals, each display angle interval corresponds to an interval angle value. This step can obtain the interval angle value corresponding to the current display angle interval. The maximum and minimum angle values ​​in this interval angle value can be recorded as the interval angle values ​​of the current display angle interval. Furthermore, the interval angle values ​​corresponding to each display angle interval formed in this embodiment are the same, and the angle amplitude corresponding to the interval angle value can be regarded as the set rotation step size in this embodiment.

[0084] In this embodiment, after knowing the interval angle values ​​of the current display angle range, the maximum and minimum angle values ​​in the interval angle values ​​can be added to the angle amplitude representing the set rotation step size, and the interval angle value formed by the newly obtained maximum and minimum angle values ​​represents the newly determined display angle range.

[0085] It can be understood that in this case, the display angle range of the target vehicle's view rotation has changed, which is equivalent to redefining the display angle range based on the current display angle range.

[0086] The above technical solution in this embodiment provides a specific process for determining the current display angle range in the automatic view rotation mode. The display angle range determined in this way better realizes the automatic uniform rotation of the panoramic view of the target vehicle.

[0087] Based on this first optional embodiment, determining the display angle range according to the current display angle range and the corresponding rotation stage in the passive rotation mode can be further specified as the following steps:

[0088] b11) Determine the interval angle value of the current display angle interval.

[0089] In this embodiment, when the 360-degree panorama is divided into multiple display angle intervals, each display angle interval corresponds to an interval angle value, which is recorded as the interval angle value of the display angle interval. Preferably, this embodiment performs a uniform 360-degree division, thus ensuring that the interval angle value is the same for each display angle interval. This step allows the acquisition of this interval angle value.

[0090] b12) When the passive rotation mode is in the third-party sliding control execution stage, the angle range to be displayed is determined based on the interval angle value and the current sliding distance of the sliding trajectory formed by the third-party sliding control.

[0091] In this embodiment, in the passive rotation mode, when the third-party sliding control is in the execution phase, a method for determining the display angle range can be established. The sliding distance of the third-party sliding control can be associated with the rotation angle of the view. The larger the sliding distance within the same time interval, the larger the rotation angle that drives the view to rotate. At the same time, each display angle range also corresponds to an interval angle value. Therefore, based on the rotation angle and the interval angle value of the display angle range, the current display angle range corresponding to the third-party sliding control at the response execution time can be effectively determined.

[0092] Furthermore, determining the angle range to be displayed based on the interval angle value combined with the current sliding distance of the sliding trajectory formed by the third-party sliding control can be specified as follows:

[0093] b121) Determine the current sliding distance based on the sliding coordinate points associated with the sliding trajectory formed by the third-party sliding control.

[0094] In this embodiment, this step and the following steps can be considered as the process of determining the current display angle range when the view is in the passive rotation mode and in the execution stage of third-party sliding control. Specifically, this step can obtain the sliding coordinate point that forms the sliding trajectory when the third-party sliding control is applied to the screen display area, and the current sliding distance can be determined based on the sliding coordinate point.

[0095] b122) Determine the sliding rotation angle corresponding to the current sliding distance based on the preset distance angle mapping information.

[0096] In this embodiment, mapping information can be pre-set for the sliding distance under passive rotation of the view. This mapping information can be a mapping between the sliding distance and the angle to be rotated, which is denoted as distance-angle mapping information in this embodiment. This step can find the corresponding angle for the current sliding distance in the distance-angle mapping information and record it as the sliding rotation angle.

[0097] b123) If the sliding rotation angle is less than the set angle threshold, then the current display angle range is kept as the display angle range.

[0098] In this embodiment, to avoid the impact of accidental touches on the screen interface by the operator on the view rotation, a touch response condition is set. This touch response condition is referred to as the orientation adjustment condition. For example, the orientation adjustment condition can be determined by a set angle threshold. If the sliding rotation angle is less than the set angle threshold, it is considered that the current movement may be an accidental touch by the operator, or the sliding angle is lower than the angle value of the display angle range. In this case, this step can remain unchanged while keeping the previously determined current display angle range unchanged.

[0099] The set angle threshold can preferably be set to the angle amplitude of the interval corresponding to the displayed angle range, but the set threshold is not greater than twice the angle amplitude.

[0100] b124) If the sliding rotation angle is greater than or equal to the set angle threshold, then the angle range to be displayed is determined according to the interval angle value of the current display angle range and the set rotation step size.

[0101] In this embodiment, when the sliding rotation angle is greater than or equal to the set angle threshold, it is considered that the adjustment conditions of the display angle range are met. At this time, the maximum and minimum angle values ​​in the current display angle range can be added to the angle amplitude as the set rotation step size, respectively, to obtain new maximum and minimum angle values, thereby forming a new range angle value. This new range angle value represents the adjusted display angle range.

[0102] b13) In the passive rotation mode, which corresponds to the buffer rotation stage after the third-party sliding control stops, the angle range to be displayed is determined based on the interval angle value and the sliding rate when the third-party sliding control stops.

[0103] In this embodiment, when the passive rotation mode is in the buffer rotation phase after the third-party sliding control stops, the implementation of determining the display angle range can first determine the buffer parameters by the sliding rate when the third-party sliding control stops, and further determine the acceleration value used for deceleration in the buffer phase. Finally, the current display angle range of the buffer phase can be determined based on the acceleration value, the sliding rate and the time interval to the stop time.

[0104] Furthermore, determining the angle range to be displayed based on the angle range value and the sliding rate when the third-party sliding control stops can be specified as follows:

[0105] b131) Obtain the sliding rate and sliding stop position corresponding to the third-party sliding control stop time, and determine the time interval from the third-party sliding control stop time to the response execution time.

[0106] In this embodiment, this step and the following steps can be considered as the process of determining the current display angle range when the view is in the buffer rotation phase in passive rotation mode. Specifically, this step can first obtain the data information required for determining the current display angle range during the buffer phase, such as the sliding rate and the sliding stop position. The sliding stop position can be considered as the display angle range determined when the third-party sliding control stops, or the display angle range to which the view has rotated. This step can also obtain the time interval from the time when the third-party sliding control stops to the time of response execution.

[0107] b132) Determine the buffer acceleration value based on the sliding rate and the pre-given buffer parameters.

[0108] In this embodiment, the deceleration buffer parameter can be an empirical value determined in advance during the method design phase through training and testing in different application scenarios. This deceleration buffer parameter can be a power value or a logarithmic value; this embodiment does not impose any specific limitations.

[0109] In one implementation, this step can be achieved by multiplying the sliding rate by the deceleration buffer parameter, and the resulting product value can be determined as the buffer acceleration value. It is understood that this buffer acceleration value is specifically used to decelerate the sliding rate at the point of stop, ensuring that the view stops rotating after a certain period of buffer rotation.

[0110] b133) Determine the buffer rotation angle based on the buffer acceleration value and the time interval.

[0111] For example, this step can determine the sliding distance generated from the moment the third-party sliding control stops to the moment the response is executed, based on the buffer acceleration value, the sliding rate, and the time interval. Then, the buffer rotation angle formed by the buffer rotation within the time interval can be determined again by combining the distance angle mapping information described in the above embodiments.

[0112] b134) Determine the angle range to be displayed based on the interval angle value and the buffer rotation angle.

[0113] In this embodiment, this step can also compare the buffer rotation angle with the angle amplitude described in the above embodiment. When the buffer rotation angle is less than the angle amplitude, it is considered that the angle range to be displayed is still within the display angle range determined at the time when the third-party sliding control stops. Alternatively, when the buffer rotation angle is equal to the angle amplitude, it is considered that the adjustment condition of the angle range to be displayed has been met, and a new angle range to be displayed can be determined through the display angle range determined at the time when the third-party sliding control stops. In addition, if the buffer rotation angle is greater than the angle amplitude, the ratio of the angle amplitude to the buffer rotation angle can be calculated. The specific value of the rounded ratio can be considered as the number of times the angle amplitude is increased based on the display angle range corresponding to the time when the third-party sliding control stops. The display angle range corresponding to the finally determined interval angle value can be considered as the angle range to be displayed to be determined.

[0114] The above-described technical solution in this embodiment provides a specific process for determining the current display angle range in the passive rotation mode of the view. The display angle range determined in this way better realizes the free speed rotation of the target vehicle view with the third-party sliding control, as well as the buffered view rotation after the sliding control stops, thus enriching the display format of the panoramic view of the target vehicle.

[0115] It should be noted that, unlike existing methods that directly rotate the 3D model associated with the target vehicle to display images of the target vehicle from different perspectives, this embodiment achieves the display of the target vehicle's view by drawing the corresponding image frames within the desired angle range.

[0116] It's important to know that drawing on image frames can be achieved using drawing tools. Generally, images are displayed on the screen in units of frames. Drawing on an image frame using a drawing tool is equivalent to creating a drawing frame for that image frame. Furthermore, considering that each image frame corresponds to a specific viewing angle range, and that there is a certain rotation time within that range, it's equivalent to needing to draw multiple frames to ensure that the entire viewing angle range is used to present the image content of that frame.

[0117] This embodiment is equivalent to decomposing the display of the image frame to be displayed within the range of angles into multiple painting frames to be displayed. Each painting frame needs to be drawn using a painting tool. In the process of drawing the image frame to be displayed using a painting tool, in order to ensure the smoothness of the painting frame formed in the view display, it is necessary to ensure that the timing of the drawing is synchronized with the frame event execution time of the execution device.

[0118] In this embodiment, the execution device can be considered the execution subject of the method provided in this embodiment, and the frame events of the execution device can be considered as the drawing frame events of the execution device. In order to achieve the alignment of the execution time of the drawing tool and the frame events of the execution device, this embodiment can listen to the drawing frame events of the execution device to obtain the start execution time of each drawing frame event. This allows the drawing tool to draw the image frame to be displayed in each drawing frame event at the execution time of the drawing frame event, and finally the drawing frame to be displayed can be displayed on the screen interface as the image frame to be displayed.

[0119] As described above, displaying an image frame is equivalent to drawing multiple frames of the image frame to be displayed. In one implementation of multi-frame drawing, after the drawing of the relevant image frame to be displayed is completed in accordance with the execution conditions of the drawing frame event, the execution time corresponding to the next drawing frame event can be directly monitored. The execution time of the determined next drawing frame event is used as the execution time of the new image frame to be displayed. Thus, after the execution time of the new image frame to be displayed is reached, the determined image frame to be displayed is drawn and displayed again.

[0120] The display area of ​​the drawing frame to be displayed in this step is the screen display area. This screen display area can be considered as the display area of ​​the target vehicle view. This display area can be the entire screen interface or a set area on the screen interface.

[0121] As a second optional embodiment of this example, based on the above embodiment and following the above description, the specific implementation process of displaying the image frame to be displayed can be described as follows:

[0122] a2) Obtain the event execution time of the painting event corresponding to the image frame to be displayed that has been pre-listened.

[0123] In this embodiment, the timing of the event execution can be obtained by listening to the events of the drawing frame in advance.

[0124] b2) After the event execution time is reached, the image frame to be displayed is drawn and displayed based on the drawing attribute information of the drawing tool and the image data information of the image frame to be displayed.

[0125] In this embodiment, after the execution time of the execution logic reaches the event execution time, it is equivalent to achieving time alignment between the frame event of the execution device and the painting event, thus allowing the painting of the current image frame to be performed through this step. The painting attribute information of the painting tool may include the width and height information of the painting frame to be formed, and may also include the device resolution information when the painting tool is running. The image data information may be the pixel information of the pixels in the current image frame, such as color value and resolution. This step can use the painting tool combined with the acquired painting information to complete the painting of the corresponding painting frame event of the image frame to be displayed, thereby forming the image frame to be displayed. This image frame to be displayed can be displayed in real time in a global view display format in the screen display area.

[0126] It should be noted that the event execution time needs to be monitored in advance. In this embodiment, after the execution of a painting frame event is completed, the event execution time of the next painting frame event can be monitored directly to enable continuous painting of the image frame to be displayed within the corresponding rotation duration.

[0127] In this embodiment, image frames are drawn in the form of drawing frame events, which spans the entire view display of the target vehicle. Regardless of the view rotation mode or different view display modes, as long as there is a need to draw image frames, the above steps in this embodiment are required to implement image frame drawing.

[0128] It is important to note that the time interval between two adjacent drawing frame events is not constant. In view rotation mode, if the rotation rate of the view is adjusted, i.e., the switching speed of the image frames presented within the display angle range is adjusted, the execution time of the drawing frame event will also be adjusted accordingly. For example, when the rotation speed generated by the third-party sliding control increases, the time interval between two adjacent drawing frame events will shorten accordingly; conversely, when the rotation speed generated during the buffer rotation phase after the third-party sliding control stops gradually slows down, the time interval between two adjacent drawing frame events will lengthen accordingly. The specific execution time of the drawing frame event can be predetermined through the listening steps of this embodiment.

[0129] The technical solution described in this embodiment replaces the existing view display method of rotating the 3D model of the target vehicle by drawing on image frames using a drawing tool. Furthermore, the drawing process incorporates listening to drawing frame events to ensure alignment between the drawing timing and the execution time of the frame events on the execution device. This technical solution significantly reduces the waste of computing resources and effectively solves the problems of lag and stuttering in view display.

[0130] As a third optional embodiment of this embodiment, based on the above embodiments, when the target object is a target vehicle, the following steps can be further optimized:

[0131] a3) In response to a door opening display operation triggered relative to the target vehicle, enter the door opening view display mode of the target vehicle, and display the door opening view according to the set door opening display strategy.

[0132] It should be noted that this third optional embodiment adds panoramic view implementation operation in other view display modes to the provided method. The preferred other view display mode is the car door view display mode, which can be entered by triggering the car door display function, or by touching or clicking the cursor on the car door displayed in the screen display area. This embodiment can analyze from the above triggers to determine that there is a need to display the car door open, which is equivalent to needing to perform a car door opening operation.

[0133] By entering the car door view display mode through this step, you can display the car door view according to the corresponding car door display strategy. The car door display strategy can be used to limit the display execution logic of the car door view. One display execution logic is to display the car door opening process as a slow-in and slow-out animation. For example, start displaying the opening of the car door at a slow rotation speed, then gradually increase the display rotation speed, and after rotating to a certain display angle range, start to reduce the display rotation speed again and gradually maintain the speed at a low value to start uniform rotation, or directly reduce the rotation speed to 0 and then start uniform rotation at a certain speed.

[0134] In this embodiment, the rotation rate involved in the animation implementation using the car door opening display strategy for easing in and out can be determined by the buffer parameters described above.

[0135] b3) Upon receiving the end trigger of the car door view display, control the target vehicle to enter the view display in automatic rotation mode.

[0136] In this embodiment, after entering a specific view display mode, the user can exit the corresponding view display mode based on the received end trigger operation. For example, after entering the car door view display mode through the above steps, this step can be used to determine whether to exit the car door view display.

[0137] Specifically, the end trigger for the car door view display can be achieved by directly triggering the car door view display end control; alternatively, it can be automatically generated when no other operation commands are received after a set time period of car door view display. Based on the end trigger achieved in the above ways, this step can be used to directly enter the automatic view rotation mode to continue object display in this mode. At this time, the object display in the automatic view rotation mode can either continue the automatic view rotation display while maintaining the car door state, or it can restore the target vehicle's default state (such as the car door closed state) for automatic view rotation display.

[0138] Furthermore, if a rotation operation related to a third-party sliding control is detected in the door-opening view display mode, the system can subsequently respond to the trigger of the third-party sliding control and enter a passive view rotation mode, continuing to display the target vehicle's view in this mode. Similarly, the object display when transitioning from the door-opening view display mode to the passive view rotation mode can either continue the passive view rotation display while the door is open, or revert to the target vehicle's default state for passive view rotation display.

[0139] It is understood that the object display method provided in this embodiment is not limited to the view display mode mentioned in the embodiment. It can also display other functions, such as triggering the magnification display of a certain local image area of ​​the image frame presented in the screen display area, and then displaying the magnified high-definition image of the local image area.

[0140] The above technical solution in this embodiment provides a feature description of other display formats for objects, which better enriches the diversity of object display functionality.

[0141] Furthermore, as one implementation of displaying the car door view, the process of displaying the car door view according to the set car door display strategy can be specified as follows:

[0142] a31) Obtain multiple door opening image frames captured when the target vehicle is in the open door state, and each door opening image frame corresponds to a different display angle range.

[0143] In this embodiment, during the image capture stage, image capture is not limited to one shooting state for different display angle ranges. It can capture images of the entire vehicle exterior, the interior of the target vehicle, and even the target vehicle with its door open. Therefore, this step can obtain images of the opened door captured relative to different display angle ranges while the door is open.

[0144] This embodiment provides an implementation method for displaying a car door view using a pre-defined car door display strategy in steps a32) and a33). In this implementation, the image frame showing the car door opening state is required to rotate the view using a soft-in / soft-out mechanism. The soft-in / soft-out during view rotation can be achieved by providing different view rotation rates for different display angle ranges. Therefore, the view rotation rate corresponding to different display angle ranges can be determined first through step a32).

[0145] a32) Based on the predetermined buffer parameters and average rotation speed, determine the rotation rate of the view when rotating to different display angle ranges.

[0146] In this embodiment, the view display with ease-in and ease-out can be specifically described as follows: In a 360-degree view display, 180 degrees can be used as the threshold for ease-in and ease-out. This ensures that the view rotation rate gradually accelerates during the view rotation from 0 degrees to 180 degrees, and that the display angle range corresponding to 180 degrees has a pre-set high rotation rate, which can be a pre-set average rotation speed. In the view rotation from 180 degrees to 360 degrees, the view rotation rate gradually decelerates, so that the display angle range corresponding to 360 degrees has a relatively low rotation rate, or the rotation rate is directly reduced to 0.

[0147] To achieve the aforementioned view rotation effect, this embodiment can determine different buffer parameters for different display angle intervals. For example, this embodiment can set the buffer parameters in exponential form, where the exponent can be an empirical value determined through training and testing in different scenarios during the method design phase, and this exponent is set as a constant value. The base can be determined based on the number of display angle intervals divided by 360 degrees. For example, when 360 degrees are divided into 36 display angle intervals, the ratio of 1 to 18 (half of 36) can be used as the growth step of the base. This base determines an initial value as the base value of the first display angle interval. For subsequent display angle intervals up to 180 degrees, the base is increased by this growth step based on the base value of the previous display angle interval; for display angle intervals after 180 degrees, the base is decreased by this growth step based on the base value of the previous display angle interval.

[0148] The above-described implementation method can determine a buffer parameter for each of the different display angle ranges corresponding to 360 degrees. This step can determine the product of the buffer parameter and the set average rotation speed as the view rotation rate corresponding to the corresponding display angle range.

[0149] Based on the view rotation speed of each display angle interval, the interval between switching from the opening door image in the display angle interval to the opening door image in the next display angle interval can be determined. It can be found that the faster the view rotation speed, the shorter the interval required for switching.

[0150] a33) During the rotation according to the rotation speed of each view, the corresponding car door image frames to be displayed under different display angle ranges are displayed.

[0151] In this embodiment, the process of displaying the car door view is equivalent to rotating the view according to the view rotation speed corresponding to each of the above display angle intervals. For each display angle interval, when it is the current display angle interval, the corresponding car door image can be obtained. Therefore, this step can also listen to the drawing frame event to draw the car door image corresponding to the current display angle interval. The drawing process is the same as described in the above embodiment, and will not be repeated here. Finally, the car door image can be displayed in the screen display area in the form of a car door state drawing frame.

[0152] To facilitate a better understanding of the object display method provided in this embodiment, Figure 2 This is an example flowchart of the object display method provided in the embodiments of this disclosure. Figure 2 As shown below, an exemplary process is given to illustrate the execution of the object display method in a practical application. The target object is described using a target vehicle as an example, and may specifically include:

[0153] S1. Trigger the view display mode of the target vehicle and load image frames captured in different panoramic display angle ranges.

[0154] S2. Is loading complete? If not, proceed to step S3; if yes, proceed to step S4, S5, or S12.

[0155] S3. Display the setting loading animation on the screen interface and display the corresponding image frames at the set resolution and display angle range, then return to continue executing S2.

[0156] S4. When the view rotation mode is the automatic view rotation mode, determine the angle range to be displayed based on the comparison result of the determined rotation interval duration and the rotation duration, and execute step S8.

[0157] S5. If the view rotation mode is the passive view rotation mode, determine the current passive rotation stage.

[0158] S6. If the passive rotation stage is the third-party sliding control execution stage, then determine the angle range to be displayed based on the current sliding distance of the sliding trajectory formed by the third-party sliding control, and execute step S8.

[0159] S7. If the passive rotation stage is a buffer rotation stage after the third-party sliding control stops, then determine the angle range to be displayed based on the sliding rate when the third-party sliding control stops, and execute step S8.

[0160] S8. Obtain the image frame to be displayed corresponding to the angle range to be displayed.

[0161] S9. Obtain the event execution time of the painting frame event corresponding to the pre-listened image frame to be displayed.

[0162] S10. When the event execution time is reached, the image frame to be displayed is drawn and displayed based on the drawing attribute information of the drawing tool and the image data information of the image frame to be displayed.

[0163] S11. Listen for the next event execution time of the next drawing frame event, and use it as the event execution time of the new drawing frame event. Return to step S4 or step S5, and re-execute the operation of determining the angle range to be displayed until the termination information of the view display is received, or the trigger of other view display modes is received.

[0164] S12. In response to the triggered door opening operation, enter the door opening view display mode and display the door opening view according to the set door opening display strategy.

[0165] S13. After receiving the end trigger of the car door view display, enter the automatic view rotation mode to display the view of the target vehicle.

[0166] Figure 3 This is a schematic diagram of an object display device provided in an embodiment of the present disclosure. This embodiment is applicable to situations where a target object is displayed in a 360-degree panoramic view or at angles within a certain range. The device can be implemented by software and / or hardware and can be configured in a terminal and / or server to implement the object display method in this embodiment of the present disclosure. Specifically, the device may include: a first display module 31 and a second display module 32.

[0167] The first display module 31 is used to trigger the view display mode of the target object and display an image frame of the target object; the image frame is an image frame in the image set, the image set includes multiple image frames corresponding to the target object, and each image frame corresponds to a different display angle range;

[0168] The second display module 32 is used to respond to the view rotation command in the current view rotation mode, determine the image frame to be displayed from the image set based on the current display angle range corresponding to the current display image frame and the rotation information in the view rotation mode, and display the image frame to be displayed.

[0169] This embodiment provides an object display device that pre-captures image frames from different viewing angles within a 360-degree omnidirectional range for each target object to be displayed. By displaying these image frames from different viewing angles, the device visually simulates the 3D display effect of existing 3D models. This technical solution eliminates the need to construct 3D models for each object, significantly reducing the cost and difficulty of object display and minimizing the waste of computing resources. It effectively solves the problems of lag and stuttering in view display. Furthermore, in the object display implemented using this embodiment, the required image frames for the object can be determined based on the current view rotation mode. That is, different view rotation modes correspond to different image frames, thus enriching the display formats and showcasing diverse panoramic views of objects.

[0170] Furthermore, the first display module 31 may specifically include:

[0171] An automatic display determination unit is used to determine the display angle range based on the current display angle range and the uniform rotation rate corresponding to the automatic rotation mode when the view rotation mode is automatic rotation mode.

[0176] The time interval between the response execution time and the entry time of the interval is determined as the rotation interval duration;

[0177] If the rotation interval is less than the rotation duration, then the current display angle range is maintained as the display angle range;

[0178] If the rotation interval duration reaches the rotation duration, then the angle range to be displayed is determined based on the interval angle value of the current display angle range and the set rotation step size.

[0179] Furthermore, the passive display of the defined unit may specifically include:

[0180] An angle determination subunit is used to determine the interval angle value of the current display angle interval;

[0181] The first determining subunit is used to determine the angle range to be displayed based on the interval angle value and the current sliding distance of the sliding trajectory formed by the third-party sliding control when the passive rotation mode is in the third-party sliding control execution stage.

[0182] The second determining subunit is used to determine the angle range to be displayed based on the interval angle value and the sliding rate when the third-party sliding control stops, corresponding to the buffer rotation stage after the third-party sliding control stops in the passive rotation mode.

[0183] Furthermore, the first determined subunit can specifically be used for:

[0184] The current sliding distance is determined based on the sliding coordinate points associated with the sliding trajectory formed by the third-party sliding control.

[0185] Based on the preset distance-angle mapping information, determine the sliding rotation angle corresponding to the current sliding distance;

[0186] If the sliding rotation angle is less than the set angle threshold, then the current display angle range is kept as the display angle range;

[0187] If the sliding rotation angle is greater than or equal to the set angle threshold, then the angle range to be displayed is determined according to the interval angle value of the current display angle range and the set rotation step size.

[0188] Furthermore, the second determined subunit can specifically be used for:

[0189] Obtain the sliding rate and sliding stop position corresponding to the stop time of the third-party sliding control, and determine the time interval from the stop time of the third-party sliding control to the response execution time;

[0190] The buffer acceleration value is determined based on the sliding rate and the pre-given buffer parameters.

[0191] The buffer rotation angle is determined based on the buffer acceleration value and the time interval.

[0192] The angle range to be displayed is determined based on the interval angle value and the buffer rotation angle.

[0193] Furthermore, the conditions for the view rotation mode to be automatic rotation mode include: receiving a trigger operation for the automatic view rotation function; or, not detecting the use of other view rotation modes within a set interval.

[0194] The conditions under which the view rotation mode is a passive rotation mode include: detecting the presence of third-party sliding control in the screen display area where image frames are displayed.

[0195] Furthermore, the second display module may perform the step of displaying the image frame to be displayed, which may include:

[0196] Obtain the event execution time of the painting event corresponding to the image frame to be displayed that has been pre-listened;

[0197] Upon reaching the event execution time, the image frame to be displayed is drawn and displayed based on the drawing attribute information of the drawing tool and the image data information of the image frame to be displayed.

[0198] Furthermore, the device may also include:

[0199] The door opening view module is used to, when the target object is a target vehicle, respond to a door opening display operation triggered relative to the target vehicle, enter the door opening view display mode of the target vehicle, and display the door opening view according to the set door opening display strategy.

[0200] The view display module is used to control the target vehicle to enter the view display mode of automatic rotation after receiving the end trigger of the view display of the car door.

[0201] Furthermore, the car door view module can be specifically used for:

[0202] Multiple open door image frames captured when the target vehicle is in the open door state are obtained, and each open door image frame corresponds to a different display angle range;

[0203] Based on the predetermined buffer parameters and average rotation speed, determine the rotation rate of the view when rotating to different display angle ranges;

[0204] During the rotation according to the rotation speed of each view, the corresponding car door image frames to be displayed under different display angle ranges are displayed.
