[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0037] Hereinafter, the terms "including", "having" and their cognates, which may be used in various embodiments of the present invention, are intended only to indicate specific features, numbers, steps, operations, elements, components or combinations of the foregoing items, and should not be understood as first excluding the existence of one or more other features, numbers, steps, operations, elements, components or combinations of the foregoing items or adding the possibility of one or more features, numbers, steps, operations, elements, components or combinations of the foregoing items.

[0038] Furthermore, the terms “first”, “second”, “third”, etc. are merely used for distinguishing descriptions and are not to be understood as indicating or implying relative importance.

[0039] Unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meanings as those generally understood by those skilled in the art to which the various embodiments of the present invention belong. The terms (such as those defined in generally used dictionaries) will be interpreted as having the same meanings as the contextual meanings in the relevant technical field and will not be interpreted as having idealized meanings or overly formal meanings unless clearly defined in the various embodiments of the present invention.

[0040] Reference Figure 1 , showing a flow chart of a first demonstration method provided by an embodiment of the present invention, the demonstration method provided by an embodiment of the present invention is applied to a computer device, and the computer device stores an animation corresponding to each disassembly step of a three-dimensional model of a device to be demonstrated.

[0041] It is understandable that, compared with small industrial equipment, the disassembly of large industrial equipment is usually completed by multiple staff members. Therefore, if a real-life disassembly operation video of large industrial equipment is shot, it must be shot from the perspectives of multiple staff members, resulting in multiple videos. If the disassembly training requires users to watch videos from multiple perspectives, it will be difficult for users to clearly understand the relationship between the disassembly steps in different videos and to reasonably understand the disassembly process of shared equipment. In addition, large industrial equipment cannot be disassembled because it is in a working state for a long time, so it is impossible to produce a corresponding real-life disassembly video.

[0042] Based on the above reasons, the embodiment of the present invention first three-dimensionally models the industrial equipment used to demonstrate the disassembly process, that is, the equipment to be demonstrated. After obtaining the three-dimensional model, animations corresponding to each disassembly step of the three-dimensional model are produced based on the three-dimensional model, and all animations are stored in a computer device so that the computer device can play the animations at the appropriate time. As a result, the embodiment of the present invention enables the disassembly training of industrial equipment of different sizes to be completed online; and the disassembly training of equipment in working state or equipment in non-working state can be realized through corresponding animations, making the disassembly training more flexible.

[0043] Based on this, the demonstration method provided by the embodiment of the present invention includes:

[0044] S110, responding to the animation play request, determining a target disassembly step corresponding to the animation play request.

[0045] That is, after receiving the animation playback request, the computer device in the embodiment of the present invention will determine which disassembly step of the three-dimensional model the user wants to know based on the animation playback request, that is, the target disassembly step, and then the computer device will play the animation corresponding to the target disassembly step.

[0046] S120, controlling the animation corresponding to each disassembly step before the target disassembly step to be played in a forward order, and controlling the animation corresponding to each disassembly step after the target disassembly step to be played in a reverse order.

[0047] That is, the embodiment of the present invention plays the animations corresponding to the steps before and after the control target disassembly step before playing the animation corresponding to the target disassembly step.

[0048] To better illustrate the playback logic provided by the embodiment of the present invention, please refer to Figure 2 , shows an animated Gantt chart provided by an embodiment of the present invention, wherein the vertical axis is the step name and the horizontal axis is the time in seconds.

[0049] Furthermore, when the user wants to play the animation corresponding to step 4, steps 1 to 3 will be played one by one in positive order, that is, the animation from the 0th second to the 4.5th second will be played, and steps 5 to 8 will be played one by one in reverse order, that is, the animation from the 9th second to the 5.5th second will be played.

[0050] As a result, when the user watches the animation corresponding to any disassembly step, the animations corresponding to other disassembly steps will match the animation corresponding to the current disassembly step. For example, when the user watches the animation corresponding to step 4, the animations corresponding to the steps before step 4 must be played in forward order, and the animations corresponding to the steps after step 4 must be played in reverse order, so that the user clearly knows the disassembly steps that should be performed before and after step 4.

[0051] In addition, it is understandable that if there are no other steps before or after the target disassembly step, the control steps to be executed by the computer device can be set according to the actual situation. For example, in one feasible way, if there are no other steps before or after the target disassembly step, the computer device only controls the animation corresponding to each disassembly step before the target disassembly step to be played in positive order, or controls the animation corresponding to each disassembly step after the target disassembly step to be played in reverse order.

[0052] Optionally, in order to ensure the effect of disassembly training and the user's experience when watching the animation, in a feasible method provided by an embodiment of the present invention, specific reference may be made to Figure 3 , shows a schematic flow chart of a second demonstration method provided by an embodiment of the present invention, that is, S120 includes:

[0053] S121, if the animation playback request is the first response, or the target disassembly step is inconsistent with the target disassembly step corresponding to the animation playback request responded to last time, then control the animation corresponding to each disassembly step before the target disassembly step to be played in forward order, and control the animation corresponding to each disassembly step after the target disassembly step to be played in reverse order.

[0054] That is, after receiving the animation playback request, the computer device in the embodiment of the present invention will determine whether the user triggers the animation playback request for the first time. If not, it will also determine whether the target disassembly step corresponding to the currently received animation playback request is consistent with the target disassembly step corresponding to the last received animation playback request, such as whether the user wanted to watch the animation corresponding to step 1 last time, and the user wants to watch the animation corresponding to step 3 this time.

[0055] If the user triggers the animation playback request for the first time, that is, the animation playback request is responded to for the first time, or the target disassembly step corresponding to the current animation playback request is inconsistent with the target disassembly step corresponding to the animation playback request responded to last time, then in order to ensure that the user can clearly know the steps to be executed before and after the target disassembly step, the embodiment of the present invention controls the animation corresponding to each disassembly step before the target disassembly step to be played in forward order, and controls the animation corresponding to each disassembly step after the target disassembly step to be played in reverse order.

[0056] If it is not the first time that the animation playback request is triggered, and the target disassembly step corresponding to the current animation playback request is consistent with the target disassembly step corresponding to the last responded animation playback request, the computer device can play the animation corresponding to the target disassembly step normally.

[0057] In order to further ensure the user's experience when watching animation, in a feasible method provided in an embodiment of the present invention, specific reference can be made to Figure 4 , showing a flow chart of a third demonstration method provided by an embodiment of the present invention, in which the computer device stores a disassembly animation of the three-dimensional model of the device to be demonstrated, the disassembly animation includes an animation corresponding to each disassembly step, and the animation playback request includes a disassembly animation playback time;

[0058] Based on this, after S110, the method further includes:

[0059] S130, if the target disassembly step is consistent with the target disassembly step corresponding to the animation play request responded last time, then control the animation corresponding to the target disassembly step to play according to the disassembly animation play time of the last animation play request and the disassembly animation play time of the animation play request.

[0060] It is understandable that when the target disassembly step corresponding to the animation playback request triggered by the user last time is consistent with the target disassembly step corresponding to the animation playback request triggered currently, it means that the user wants to watch a certain segment in the animation corresponding to the same target disassembly step. Therefore, the computer device will play according to the play time in the animation playback request triggered by the user last time and the play time in the animation playback request triggered currently by the user, thereby ensuring that the user can watch the corresponding segment. Exemplarily, if the play time in the animation playback request responded last time is the 1st second, and the play time in the animation playback request responded this time is the 2nd second, then the computer device will play the animation from the 1st second to the 2nd second.

[0061] In the demonstration method provided by an embodiment of the present invention, a computer device is based on the pre-stored animation corresponding to each disassembly step of the three-dimensional model of the device to be demonstrated, so that when a user-triggered animation playback request is received and the target disassembly step corresponding to the animation playback request is determined, the animation corresponding to each disassembly step before the target disassembly step is controlled to be played in forward order, and the animation corresponding to each disassembly step after the target disassembly step is controlled to be played in reverse order.

[0062] Based on this, the embodiment of the present invention enables the user to clearly know the disassembly steps that should be performed before and after the target disassembly steps, thereby improving the user's learning efficiency; and, the embodiment of the present invention stores all animations of the three-dimensional model of the equipment to be demonstrated in the computer device, so that the disassembly training of industrial equipment of different sizes can be completed online, thereby improving the flexibility of the disassembly training.

[0063] Optionally, in an implementation manner provided by an embodiment of the present invention, before S110, the method further includes:

[0064] Obtain a three-dimensional model of the device to be demonstrated;

[0065] According to the disassembly steps of the device to be demonstrated, an animation corresponding to each disassembly step of the three-dimensional model is produced.

[0066] That is, the embodiment of the present invention first obtains the three-dimensional model of each device to be demonstrated, and then generates an animation corresponding to the disassembly of the three-dimensional model according to the disassembly steps of the device.

[0067] It is understandable that the method for obtaining the three-dimensional model of the device to be demonstrated can be set according to actual conditions. In a feasible method provided by an embodiment of the present invention, the three-dimensional model of the device to be demonstrated is obtained by three-dimensionally scanning the device to be demonstrated.

[0068] Furthermore, after the computer device obtains the three-dimensional model, the computer device will also determine the disassembly steps of the device according to the received operation instructions, and generate animations corresponding to the disassembly steps of the three-dimensional model. For example, when the computer device receives the operation instruction of "Step 1: Disassemble the upper panel of the device", the upper panel of the three-dimensional model will be disassembled accordingly, and the disassembly process will be made into a corresponding animation.

[0069] Optionally, to ensure that the computer device can accurately determine the target disassembly step, in an implementation manner provided by an embodiment of the present invention, the computer device stores a disassembly animation of the three-dimensional model of the device to be demonstrated, the disassembly animation includes an animation corresponding to each disassembly step, the computer device also stores a start play time and an end play time of each of the animations, and the animation play request includes the disassembly animation play time;

[0070] The S110 includes:

[0071] Get the animation playback request;

[0072] According to the disassembly animation playing time in the animation playing request and the start playing time and the end playing time of each of the animations, the target disassembly step corresponding to the animation playing request is determined.

[0073] That is, the computer device in the embodiment of the present invention stores each animation, and also stores the start playing time and the end playing time of each animation. Figure 2 Taking the animated Gantt chart shown as an example, the computer device stores that the starting playing time of step 1 is 0 seconds and the ending playing time is 2 seconds, and the starting playing time of step 3 is 2 seconds and the ending playing time is 4 seconds.

[0074] Furthermore, after storing the start play time and the end play time of each step, if the computer device receives an animation play request carrying the play time, the target disassembly step that the user wants to watch will be determined according to the play time. For example, when the play time in the animation play request is 5.25 seconds, and 5.25 seconds belongs to step 4, the computer device determines that the target disassembly step is step 4.

[0075] Therefore, the computer device in the embodiment of the present invention can accurately locate the target disassembly steps corresponding to the animation playback request based on the start playback time and the end playback time of each animation, and can ensure the reasonable playback of the animation.

[0076] Optionally, to further provide flexibility in disassembly training, in a feasible manner provided in an embodiment of the present invention, the animation is loaded and rendered based on a three.js graphics framework.

[0077] It is understandable that three.js is a graphics framework based on WebGL (Web Graphics Library) encapsulation, which is widely used in the design of 3D applications in browsers. The embodiment of the present invention is based on the three.js graphics framework, so that the browser can execute the demonstration method provided by the embodiment of the present invention. As a result, the hardware requirements for users to watch the disassembly animation are reduced, the cost of disassembly training is lowered, and the flexibility of disassembly training is also improved.

[0078] Optionally, in order to improve the training effect of disassembly training, in a feasible manner provided in an embodiment of the present invention, the method further includes:

[0079] Respond to the view adjustment request and control the animation playback view to make corresponding adjustments.

[0080] That is, the computer device in the embodiment of the present invention is also equipped with a preset viewing angle adjustment interface, and when the computer device receives a viewing angle adjustment request, it will adjust the viewing angle of the current animation accordingly, so that the user can observe the disassembly process of the industrial equipment based on different viewing angles.

[0081] Furthermore, in a feasible manner provided by an embodiment of the present invention, the viewing angle adjustment of the animation is implemented through the camera viewing angle of three.js.
