detailed description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

A drone is a remotely controlled unmanned aircraft, which can establish a wireless connection with a remote control device, so that the user can implement remote control of the drone through the remote control device. Here, the remote control device may be a remote control, a combination of a remote control and a mobile terminal, or a combination of a remote control and video glasses. The application does not limit the specific implementation form of the remote control device.

Users usually need to carry out certain flight training before using the drone for official flight. Flight training can be carried out through practical operation, that is, users can directly control the drone for training in reality. However, in the actual operation, once a collision occurs due to improper control, the drone may be damaged or exploded. Therefore, in another way, UAV flight training can also be performed through flight simulation software to reduce training costs.

The flight simulation software can be installed on terminal devices such as computers, mobile phones, and smart tablets, and the terminal device with the flight simulation software installed can be called an analog terminal. When running the flight simulation software in the simulation terminal, the user can control the drone in the flight simulation software to achieve the purpose of training or entertainment.

As shown in FIG. 1 , FIG. 1 is a schematic diagram of a flight simulation scenario provided by an embodiment of the present application, wherein the simulated terminal 110 can be connected to the remote control device 120 of the drone, and the user can use the remote control device to control the display of the simulated terminal. The drone is controlled to achieve the effect of flight training.

However, the 3D scenes provided in the existing flight simulation software are all artificially constructed virtual 3D scenes, the content of the virtual 3D scenes is limited in repetition, and there is a certain gap with the real scenes, and the training effect is not satisfactory. Moreover, the existing flight simulation software is all aimed at aerial photography drones, and there is still no matching flight simulation content for the time-travelling aircraft, which cannot meet the needs of the flying-travelling aircraft pilots.

It should be noted that the aerial photography drone is aimed at ordinary consumers, its flight control is relatively stable, the flight speed is slow, and it is relatively easy to control, while the flying drone is purely manual control, the flight speed is unlimited or limited, and it is difficult to get started. Easy to blow up. Therefore, compared with aerial photography UAVs, the flight simulation requirements of flying drones are greater, and novices rely more on flight simulation to get started.

In order to solve the above problem, an embodiment of the present application provides a flight simulation method for a time-travelling aircraft. Referring to FIG. 2 , FIG. 2 is a flowchart of the flight simulation method provided by the embodiment of the present application. The method includes:

S210. Display the earth model on the display interface of the analog terminal.

S220. Determine the target location identifier according to the user's operation on the location identifier in the earth model.

S230. Load the target real three-dimensional scene corresponding to the target location identifier.

S240. According to the user's operation on the virtual joystick or the physical joystick of the remote control, perform acceleration, viewing angle adjustment or scene update processing on the target real three-dimensional scene.

As can be seen from the foregoing, the simulated terminal may be a terminal device installed with flight simulation software. The simulation terminal may include a display, a processor and a memory, wherein a computer program corresponding to the flight simulation software may be stored in the memory, the processor may execute the computer program to run the flight simulation software, and during the software running process, the processing The controller can also display the corresponding picture of the flight simulation software through the display.

When the flight simulation software is running, the screen corresponding to the earth model can be displayed by loading the earth model. The earth model can be displayed in various ways. In one embodiment, the earth model can be displayed from the perspective of observing the earth from outer space, as shown in FIG. 3 , which is a display effect diagram of the earth model provided by the embodiment of the present application.

The earth model may include multiple location markers, and the location markers may be used to identify real three-dimensional scenes corresponding to different locations. In one embodiment, the location identifiers may correspond to real locations in the real world, such as countries such as China, Russia, India, etc., of course, may also be smaller-level locations, such as Guangdong, Hunan, Hubei and other provinces, Or Guangzhou, Shenzhen, Beijing and other cities.

In one embodiment, the display manner of the earth model can be adjusted according to the user's operation on the earth model. For example, the user can rotate, zoom, and move the earth model through keyboard, mouse, remote control, touch gestures, etc. Wherein, when the earth model is enlarged, the level of the displayed location identification can be adjusted according to the degree of enlargement. For example, before zooming in, the location identifiers in the earth model can correspond to the country level, and after zooming in, the location identifiers in the earth model can correspond to the levels of provinces, cities, or urban areas.

Different locations may correspond to real three-dimensional scenes of the locations. It should be noted that the real 3D scene is the scene model corresponding to the real scene of the location. For example, if the location corresponds to a shopping mall in reality, then in the real 3D scene corresponding to the location, the corresponding location will include the shopping mall. the corresponding 3D model.

The user can input the target location through the search bar provided on the display interface, or can select the target location on the screen to determine the target location. According to the user's input or selection, the target location identifier can be determined.

After the target location identifier is determined, the real three-dimensional scene of the target corresponding to the target location identifier can be loaded, so that the flight simulation of the crossing aircraft can be performed based on the real three-dimensional scene of the target.

It can be seen that, in the flight simulation method provided by the embodiments of the present application, since the loaded scene model is a real 3D scene corresponding to the real scene, compared with the virtual 3D scene provided in the existing flight simulation software, it can provide more This kind of flight environment makes the flight training effect better.

Considering that it takes a lot of time and manpower to construct a real 3D scene manually, in an implementation manner, a model of the real 3D scene can be constructed through a 3D reconstruction technology. Specifically, when building a real three-dimensional scene of a certain place, the real scene corresponding to the place can be photographed from multiple angles to obtain a multi-angle image corresponding to the real scene. The multi-angle can include front view, side view, top view, upward view, etc., and the multi-angle image can include images captured by different devices such as satellite images and drone aerial images. Using the multi-angle images obtained by shooting, the multi-angle images can be fused through a three-dimensional reconstruction algorithm, so as to construct the real scene corresponding to the real three-dimensional scene.

Although the use of 3D reconstruction technology to build a real 3D scene saves manpower, it is still a huge workload to build a real 3D scene for all locations on the earth. Therefore, in one embodiment, since the third-party map software has built real three-dimensional scenes of various locations on the earth through the three-dimensional reconstruction technology, the third-party map software can be called by calling the application programming interface (Application Programming Interface, API), The flight simulation software of the embodiment of the present application is docked with the third-party map software, and the earth model of the third-party map software is imported during the operation of the flight simulation software, and the earth model is displayed on the display interface; After the location identification, the target location identification can be sent to the third-party map software, so that the target real three-dimensional scene corresponding to the target location identification returned by the third-party map software can be received, and the target real three-dimensional scene can be loaded.

Understandably, the third-party map software can be any software that performs three-dimensional reconstruction of the real scene, such as Google Earth, Baidu Map, AutoNavi Map, and so on.

After loading the real 3D scene of the target, the flight simulation of the traversing aircraft can be performed based on the real 3D scene of the target. In one embodiment, a time-travelling aircraft model can be generated in the loaded target real three-dimensional scene, and the time-travelling aircraft model can be associated with the flight control logic corresponding to the time-travelling aircraft, so that in a first-person perspective (First Person View, When FPV) displays the flight screen of the traversing aircraft, according to the user's operation of the virtual joystick or the physical joystick of the remote control, the real 3D scene of the target can be accelerated, the viewing angle adjusted or the scene processing is updated to achieve the effect of flight simulation.

It should be noted that the analog terminal may include a connector, which may be a wireless or wired connector, for connecting with the physical remote control, so that when connecting the physical remote control with the analog terminal, the user can operate The physical remote controller controls the generated aircraft model to obtain a more realistic flight simulation experience. Of course, the remote controller can also be a virtual remote controller, for example, the virtual remote controller can be a remote controller that uses a keyboard, a mouse, a touch screen, etc. to input control instructions.

As can be seen from the previous article, the real 3D scene can be built by 3D reconstruction technology, and the model built by 3D reconstruction technology is only the result of image fusion. Therefore, obstacles in the model, such as buildings and plants, do not have collision volumes, that is, when When flying in the real 3D scene of the target, the crossing aircraft can pass through these obstacle models without hindrance, which is inconsistent with the real flying experience. Therefore, in one embodiment, the obstacles in the target real three-dimensional scene can be identified through image recognition technology, and collision volumes can be assigned or generated for these obstacles, so that when the passing machine collides with the obstacles, it can trigger the The occurrence of any of the following events: the plane explodes, or the damage of the plane increases (the plane can be equipped with a health bar or damage bar), or, the plane returns to the position before the collision.

Further, after a collision occurs, in order to make the user have a more realistic collision experience, the category of each obstacle in the real 3D scene of the target can be determined, such as buildings, plants, objects, etc. The physical properties corresponding to the categories of the obstacles, so that when a collision event occurs between the traversing machine and the obstacle, the hit obstacle can be triggered to move and/or deform corresponding to its assigned physical properties. For example, when the crossing machine collides with a building, the building can be partially damaged, but will not move. When the crossing machine collides with a plant, the branches and leaves of the plant can be deformed, and can also respond to the collision of the crossing machine. Wind pressure produces movements such as swaying. For items, when assigning physical attributes, you can give the corresponding quality according to the volume and material of the item, so that the collision between the crossing machine and different items can have different effects. For example, small items can be displaced after being collided, and large items can be Local deformation can occur after collision.

In order to increase the fun of flight simulation training, in one embodiment, after identifying the obstacles in the target real three-dimensional scene, the target obstacles in the obstacles can be compared with other three-dimensional scenes (the three-dimensional scene can be Real 3D scene or virtual 3D scene), so that when the traversing machine collides with the designated position of the target obstacle, the effect of traversing machine transmission can be triggered, that is, other 3D scenes associated with the target obstacle can be loaded. In the other three-dimensional scene, the flight simulation of the crossing aircraft is continued.

For example, for a specific building in the target real three-dimensional scene, such as a shopping mall, the shopping mall can be associated with the three-dimensional scene inside the shopping mall, so that when the crossing machine collides with the entrance of the shopping mall or the user performs a preset interaction logic with the shopping mall , the loading of the 3D scene inside the mall can be triggered, so that the user can fly through the aircraft in the 3D scene inside the mall.

It should be noted that the other three-dimensional scenes may be real three-dimensional scenes obtained by three-dimensional reconstruction based on real scenes, or may be artificially constructed virtual three-dimensional scenes. In one embodiment, a user-defined virtual 3D scene can be created, a self-created virtual 3D scene imported by the user can be received, and the target obstacle and the imported virtual 3D scene can be established according to the target obstacle specified by the user. so as to realize the switching from the target real 3D scene to the virtual 3D scene through the target obstacle, which greatly improves the playability of the flight simulation.

Considering that the real 3D scene built by the third-party map software may be insufficient in model fineness, therefore, in an implementation manner, after loading the target real 3D scene, image enhancement processing can be performed on the image in the target real 3D scene , and display the real 3D scene of the target after image enhancement processing on the display interface, giving users better visual effects. In one example, image enhancement processing such as super-resolution, color enhancement, denoising, and sharpening can be performed on the texture of the model in the target real 3D scene.

In one embodiment, a fine model of common obstacles can also be established in advance. For example, a fine model corresponding to the tree can be established in advance for a tree, and a fine model corresponding to a common building can also be established for some ordinary buildings without landmarks. Therefore, after acquiring the real 3D scene of the target, the obstacles in the real 3D scene of the target can be identified, and after identifying the specific obstacle, the model of the specific obstacle can be replaced with the pre-established model of the specific obstacle. Refinement model, for example, all obstacles identified as trees can be replaced by any kind of pre-built fine models of trees, and some common buildings can also be replaced by any kind of pre-built fine models of common buildings, so that It can improve the fineness of the overall scene without affecting the consistency with the real scene, and provide users with a more refined flight environment.

In order to improve the authenticity of the flight simulation, in one embodiment, a designated area in the real 3D scene of the target can also be set as a restricted flight area. Countermeasures to the crossing aircraft can also trigger a pursuit event, that is, at least one police drone can be generated in the real 3D scene of the target. Hunting can improve the fun of flight simulation, and can also remind users to pay more attention to the restricted flight area in the real field.

In the process of flight simulation, when displaying in the first-person perspective, the user's manipulation of the flying machine can be responded to by accelerating or adjusting the perspective of the target real three-dimensional scene. In one embodiment, the control parameters of the riding machine can be adjusted according to the performance parameters of the riding machine selected by the user, such as the acceleration when accelerating the target real 3D scene, the rotation speed of the riding machine when the viewing angle is adjusted, etc. . By adjusting the control parameters of the riding machine, the currently generated riding machine can be more in line with the real hand feel in operation, and bring better training effects to the user.

Regarding the performance parameters of the crossing machine, in one embodiment, before generating the crossing machine in the target real three-dimensional scene, an assembly interface of the crossing machine may be provided, and the assembly interface may include various components of the crossing machine for the user to select. , such as image transmission system (camera, digital image transmission, etc.), power system (motor, ESC, propeller, etc.), rack, battery system, etc. Therefore, according to the components selected by the user, the corresponding performance parameters. In one embodiment, the model of the flying machine can also be modified accordingly according to the components selected by the user and the personalized map selected by the user, so that when switching to the third-person perspective in the flight simulation, the user can Observe the personalized traversing machine of its design.

In one embodiment, the real time of the real location corresponding to the target location identifier can also be acquired, and according to the real time, it is determined that the lighting system in the flight simulation environment is a day mode or a night mode. Since the location identifier selected by the user can be anywhere on the earth, and there is a time difference between locations that are far apart on the earth, in this embodiment, the mode of the lighting system can be changed to day or day according to the real time. In the dark night, users can have a more realistic flight simulation experience.

In one embodiment, the music corresponding to the target location identifier may also be acquired and played according to the target location identifier selected by the user. When the user selects a certain location on the earth model to perform the flight simulation of the flying machine, the location type of the selected location can be determined, and the characteristic music corresponding to the location type can be obtained and played. In one example, for example, if the user selects places such as Guangzhou and Shenzhen for flight simulation, it can be determined that the location type of the selected place is a city, and more fashionable music that matches the city can be played; if the user chooses places such as Inner Mongolia During flight simulation, it can be determined that the location type of the selected location is grassland, and music with a sense of vastness that matches the grassland can be played. Through this embodiment, the user can listen to the style music of different places when performing flight simulation in different places, which increases the fun of flight simulation.

In an embodiment, a follow-up target can also be generated in the target real 3D scene, and a motion route corresponding to the target real three-dimensional scene is obtained, and the follow-up target is controlled to move according to the motion route, wherein the The tracking target is used by the user to control the crossing machine to follow the tracking target. In this embodiment, the generated follow-up target can be any model, such as a character model, an animal model, a vehicle model, etc., which can move quickly according to a specific route as the follow-up target of the crossing machine controlled by the user, It is used to assist users to practice flying skills. Among them, due to the different topography of different places, motion routes can be generated for the real 3D scene corresponding to each different place in advance. The tracking target is generated in the corresponding real 3D scene, and the tracking target is controlled to move along the motion route corresponding to the real 3D scene in Shenzhen, and at the same time, the user can be instructed to follow the tracking target.

In one embodiment, since the crossover aircraft is often used for racing, a recording mode can be provided so that one or others can analyze the flight control records. Specifically, the recording mode can be entered according to the recording instruction of the first user. In the recording mode, the displayed FPV picture can be recorded, and the starting point, initial attitude, initial speed of the flying machine, and the first user's flight status can be recorded. During the process, all the control instructions for the traversing machine, and the recorded information can generate a record file. After obtaining the authorization of the user, the record file can be uploaded to the server, and when the server receives a request from the second user to obtain the record file, the server can send the record file to the client of the second user. The client of the second user can reproduce the FPV picture of the first user on the display interface corresponding to the second user according to the record file, and synchronously display the control instructions of the first user on the crossing machine at each moment, Therefore, the second user can study and learn the flight manipulation of the first user, so as to improve his flying skills.

When reproducing the FPV picture of the first user, the client of the second user can generate a traversing machine controlled by the first user at the starting point recorded in the recording file according to the recording file, and assign the FPV to the first user. After the initial attitude and initial speed recorded in the recording file of the crossing machine, the generated crossing machine is controlled according to the control instructions of the first user recorded in the recording file, so as to realize the operation of the customer of the second user. The terminal reproduces the FPV picture of the first user.

In another embodiment, throttle up controls, throttle down controls, pan left controls, pan right controls, pitch forward controls, pitch back controls, roll left tilt controls, and roll controls may be displayed on the display interface The right tilting control, while displaying the FPV screen, displays the rod amount and control time required for the operation represented by each control through the color band, and the rod amount and control time are in a synchronized state with the FPV screen; the display color of the color band Or the length is linked to the user's control of the physical joystick or virtual joystick. For example, the closer the user's control of the physical joystick or virtual joystick is to the amount required for the operation represented by the corresponding control, the shorter the color band. ; When the user's control time on the physical joystick or virtual joystick is closer to the control time required for the operation represented by the corresponding control, the color band will be shorter. The color band corresponding to the rod amount and the color band corresponding to the control duration cross each other, and the two gradually shorten from the two ends to the middle following the user's operation. When the end point is reached at the same time, the user's operation is determined to be successful, and the register is scored. . By correlating the FPV screen, user operation and control display content, this solution can provide users with a real experience of the traversing plane, and quickly learn how to control the joystick to make the traversing plane perform various actions and bring a good visual experience.
