Detailed Description
Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.
Before describing the specific embodiments of the present disclosure in detail, first, a simple description is given of an application scenario of the present disclosure, where the present disclosure may be applied to a vehicle management system, such as an airport management system, and a manager may monitor and manage running of each vehicle according to a running condition of each vehicle displayed by the management system, for example, query or track a current location of each vehicle, and perform flight adjustment, train number allocation, and so on according to the current location of each vehicle. The existing method for displaying the running condition of the vehicle is mainly a two-dimensional static display scheme, only displays the position of a certain vehicle on a map at a certain moment, and has relatively poor visual effect due to relatively single-sided displayed information.
The inventor notices the problem and proposes a driving condition display method, which specifically comprises the following steps:
referring to fig. 1, fig. 1 is a flowchart of a driving situation display method according to an embodiment of the disclosure, where the driving situation display method may be applied to a background management system of a vehicle, and the background management system may be installed on an electronic device, and the electronic device may be a mobile device such as a tablet computer, a smart phone, a smart television, a PDA (english: personal Digital Assistant, chinese: personal digital assistant), a portable computer, or a fixed device such as a desktop computer.
As shown in fig. 1, the method comprises the steps of:
step 101, acquiring driving parameter information of at least two driving position points of a target vehicle.
In this embodiment, a travel information storage list may be established in advance for a vehicle managed by the background management system, for example, when the vehicle managed by the background management system includes a vehicle and an aircraft (e.g., an airplane, a helicopter), a vehicle travel information storage list may be established for storing travel parameter information of each vehicle, and an aircraft travel information storage list may be established for storing travel parameter information of each aircraft. Each vehicle and aircraft may collect real-time travel data through its own positioning system (such as global positioning system GPS) and sensors (such as speed sensor, acceleration sensor, rotation angle sensor, yaw angle sensor, etc.), and upload the collected real-time travel data to a server. In a specific embodiment, the real-time travel data may include position, speed, direction, etc. data, and if the vehicle is an aircraft, the real-time travel data may also include altitude data. The background management system can acquire real-time running data of each vehicle and each aircraft from the server, preprocesses the acquired real-time running data to obtain running parameter information of the corresponding vehicles at each running position point, and stores the running parameter information of each vehicle at each running position point into the established corresponding type running information storage list to form the running parameter information of the vehicles and the aircraft at each running position point.
Such pretreatments include, but are not limited to: the method comprises the steps of performing validity recognition (such as recognizing whether position information in the real-time running data is empty or not, if so, the data is illegal, direct filtering) on the real-time running data, performing validity recognition (such as recognizing whether the position information in the real-time running data is in a preset area or not, if not, the data is invalid, direct filtering), numbering the real-time running data, uniformly converting specific information in the real-time running data (such as converting the position information expressed by longitude and latitude into world coordinates), and adding a time identifier to the real-time running data, wherein the time identifier can comprise an absolute time identifier (such as time for receiving the data from a server) and a relative time identifier (such as time difference between data of each position point and data of a first position point).
In a specific embodiment, the running parameter information of the running position point stored in the running information storage list may specifically include position information (such as world coordinates) of the point, speed information (such as speed, acceleration, angular velocity, etc.), direction information (such as direction, yaw angle, azimuth angle, etc.), running parameter information of the aircraft stored in the running information storage list may further include altitude information, and in addition, the running parameter information of the running position point stored in the running information storage list may further include a number of the position point, a relative time (such as a difference in acquisition time of data of each position point and data of the first position point), an absolute time (such as a time of receiving the data from a server), and the like, which are not particularly limited herein.
In particular, in this embodiment, a running condition display list of the vehicles may be provided on a user interface of the background management system, where the list provides the user with identifiers of the respective vehicles capable of viewing the running condition, and the user may select a vehicle to be viewed (i.e., a target vehicle) in the list, and the background management system obtains running parameter information of at least two running location points of the target vehicle from the running information storage list according to the selection of the user.
Step 102, creating a driving path passing through the at least two driving position points, and determining driving posture information of the target vehicle at the corresponding driving position points according to the pre-acquired driving parameter information.
Specifically, if the travel parameter information of the target vehicle stored in the travel information storage list relates to relatively few travel position points, the existing travel position points may be linearly interpolated according to the point numbers, relative times, absolute times, and the like in the travel parameter information of the existing travel position points to create a travel path passing through the at least two travel position points.
Determining driving posture information of the target vehicle at the corresponding driving position point according to the driving parameter information of each driving position point, for example, when the target vehicle is a vehicle, speed information and direction information of the corresponding driving position point can be obtained from the driving parameter information of each driving position point, and at least one of a tire rotation speed, a steering wheel deflection angle and a vehicle body inclination angle of the vehicle at the corresponding driving position point is determined according to the speed information and the direction information of each driving position point; when the target vehicle is an aircraft, acquiring speed information, direction information and altitude information of the corresponding driving position point from driving parameter information of each driving position point; and determining at least one of the turbine rotation speed, the attitude angle, the steering direction of a rudder, the deflection angle of a tail wing, the retraction state of a landing gear, the retraction state of a flap and the opening and closing state of a speed reducing plate of the aircraft at the corresponding driving position point according to the speed information, the direction information and the height information of each driving position point.
And 103, when the three-dimensional virtual model corresponding to the control target vehicle runs to each running position point of the running path, running according to the running posture information of the corresponding running position point, and generating a running animation.
In this embodiment, a three-dimensional virtual model may be previously established for each vehicle managed by the background management system, and the established three-dimensional virtual model may be stored in a corresponding three-dimensional model storage list, for example, a three-dimensional vehicle model storage list and a three-dimensional aircraft model storage list may be established, where the three-dimensional vehicle model storage list is used for storing each three-dimensional vehicle model, and the three-dimensional aircraft model storage list is used for storing each three-dimensional aircraft model.
After the driving path is established and the driving gesture information of the target vehicle at each driving position point is determined, a three-dimensional virtual model corresponding to the target vehicle can be obtained from a three-dimensional model storage list, and the three-dimensional virtual model is controlled to sequentially drive through each driving position point on the driving path according to the driving gesture information in a real-time scene (such as a high-precision map and a street view map) of a user interface. For example, when the target vehicle is an airplane and the corresponding running gesture information is landing gear and flap, the landing gear and flap effect is generated when the corresponding three-dimensional virtual model of the airplane is controlled to run to a certain running position point, for example, when the corresponding running gesture information is a deceleration baffle opening and the three-dimensional virtual model is controlled to run to the running position point, the deceleration baffle opening effect is generated, and therefore, the animation effect is generated through the control of the three-dimensional virtual model, and the reduction of the running path and the running gesture of the target vehicle is realized.
In addition, after the running animation is generated, the play of the running animation may be controlled according to the operation of the user. For example, the playing, stopping, fast-forwarding or fast-rewinding of the running animation can be controlled according to the playing, pause, fast-forwarding, fast-rewinding and other instructions triggered by the user.
According to the technical scheme, the driving parameter information of at least two driving position points of the target vehicle is obtained; creating a running path passing through the at least two running position points, and determining the running posture information of the target vehicle at the corresponding running position points according to the pre-acquired running parameter information; when the three-dimensional virtual model corresponding to the control target vehicle runs to each running position point of the running path, running according to the running posture information of the corresponding running position point, and generating running animation. That is, according to the technical scheme shown in the embodiment of the disclosure, the running condition of the vehicle can be displayed in a three-dimensional dynamic mode, the running path of the vehicle is displayed, the running posture of the vehicle is displayed, the displayed information is more comprehensive, and the visual effect is improved.
Fig. 2 is a flow chart of another driving situation presenting method shown in an embodiment of the present disclosure, the method comprising the steps of:
In step 201, real-time travel data of each vehicle is acquired from a server.
By way of example, the vehicle may include vehicles such as cars, taxis, coaches, and the like, and aircraft such as airplanes, helicopters, and the like. Each vehicle and aircraft can acquire real-time travel data through its own positioning system (such as a global positioning system GPS) and sensors (such as a speed sensor, an acceleration sensor, a rotation angle sensor, a yaw angle sensor, etc.), and upload the acquired real-time travel data to a server, from which a background management system can acquire real-time travel data of each vehicle and aircraft. In a specific embodiment, the real-time travel data may include position, speed, direction, etc. data, and if the vehicle is an aircraft, the real-time travel data may also include altitude data.
Step 202, preprocessing the real-time driving data to obtain driving parameter information of the corresponding vehicle at each driving position point.
Such pretreatments include, but are not limited to: the method comprises the steps of performing validity recognition (such as recognizing whether position information in the real-time running data is empty or not, if so, the data is illegal, direct filtering) on the real-time running data, performing validity recognition (such as recognizing whether the position information in the real-time running data is in a preset area or not, if not, the data is invalid, direct filtering), numbering the real-time running data, uniformly converting specific information in the real-time running data (such as converting the position information expressed by longitude and latitude into world coordinates), and adding a time identifier to the real-time running data, wherein the time identifier can comprise an absolute time identifier (such as time for receiving the data from a server) and a relative time identifier (such as time difference between data of each position point and data of a first position point).
In a specific embodiment, the running parameter information of the running position point stored in the running information storage list may specifically include position information (such as world coordinates), speed information (such as speed, acceleration, angular velocity, etc.), direction information (such as direction, yaw angle, azimuth angle, etc.) of the point, and the running parameter information stored in the list may also include altitude information for the running information storage list of the aircraft, and in addition, the running parameter information of the running position point stored in the running information storage list may also include the number, relative time, absolute time, etc. of the position point, which are not particularly limited herein.
And 203, storing the running parameter information of each vehicle at each running position point into a corresponding type of running information storage list.
In this embodiment, a travel information storage list may be established in advance for a vehicle managed by the background management system, for example, when the vehicle managed by the background management system includes a vehicle and an aircraft (e.g., an airplane, a helicopter), a vehicle travel information storage list may be established for storing travel parameter information of each vehicle, and an aircraft travel information storage list may be established for storing travel parameter information of each aircraft.
Step 204, determining a target vehicle selected by the user in the driving situation display list.
In particular, in this embodiment, a running condition display list of the vehicles may be provided on a user interface of the background management system, where the list provides the user with identifiers of the respective vehicles capable of viewing the running condition, and the user may select a vehicle to be viewed (i.e., a target vehicle) in the list, and the background management system obtains running parameter information of at least two running location points of the target vehicle from the running information storage list according to the selection of the user.
Step 205, according to the running parameter information of at least two running position points of the target vehicle selected by the user from the corresponding type of running information storage list.
It should be noted that, at this time, the running parameter information of at least two running position points of the target vehicle acquired from the running information storage list may be the running parameter information of all running position points of the target vehicle stored in the running information storage list, that is, the running parameter information acquired at this time is the running parameter information of all running position points that the target vehicle has currently generated, and there may be only one or two or more running position points, specifically, after the running parameter information of all running position points that the target vehicle has currently generated is acquired, the number of points may be determined as shown in fig. 3, if there is only one running position point data at present, the data may be stored in the path queue first for standby, and if there is two or more running position point data at present, a running path may be created.
And 206, creating a spline curve passing through the at least two running position points to obtain a running path.
Specifically, if the running parameter information of the target vehicle currently stored in the running information storage list relates to relatively few (but at least two) running position points, it is possible to linearly interpolate the existing running position points according to the point numbers, relative times, absolute times, and the like in the running parameter information of the existing running position points, and create a spline curve passing through the at least two running position points, thereby obtaining the running path.
Step 207, determining the driving posture information of the target vehicle at the corresponding driving position point according to the pre-acquired driving parameter information.
For example, when the target vehicle is a vehicle, speed information and direction information of each driving position point may be obtained from driving parameter information of the corresponding driving position point, and at least one of a tire rotation speed, a steering wheel deflection angle, and a vehicle body inclination angle of the vehicle at the corresponding driving position point may be determined from the speed information and direction information of each driving position point.
When the target vehicle is an aircraft, speed information, direction information and altitude information of the corresponding driving position point can be obtained from the driving parameter information of each driving position point; and determining at least one of the turbine rotation speed, the attitude angle, the steering direction of a rudder, the deflection angle of a tail wing, the retraction state of a landing gear, the retraction state of a flap and the opening and closing state of a speed reducing plate of the aircraft at the corresponding driving position point according to the speed information, the direction information and the height information of each driving position point.
Specifically, for example, when the target vehicle is an aircraft, a steering inclination angle θ of the current running position point may be calculated according to speed information of the current running position point, θ=arctan (ω×v/g), where ω is an angular speed, V is a speed, g is a gravitational acceleration, and an attitude angle (such as pitch angle, yaw angle, roll angle) of the aircraft is determined according to the calculated steering inclination angle θ of the current running position point; meanwhile, judging whether the height of the current running position point is lower than a preset height, if so, judging that the aircraft is in a low airspace state, and determining that the current running attitude information of the aircraft is landing gear and flap landing; further, if the height of the current running position point from the ground is 0 (i.e. the aircraft contacts the ground), the speed is greater than the first preset speed, and the acceleration is negative, determining that the current running posture information of the aircraft is the opening of the speed reducer; further, if the speed of the front running position point is smaller than a second preset speed, determining that the current running posture information of the aircraft is a stow speed reducing plate, and when the current running position point enters a taxiway, determining that the current running posture information of the aircraft is a stow flap, wherein the first preset speed is larger than the second preset speed.
Step 208, associating the driving gesture information of the target vehicle at each driving position point with the corresponding driving position point on the driving path.
Step 209, controlling the three-dimensional virtual model corresponding to the target vehicle to run on the running path, and when the three-dimensional virtual model runs to each running position point, rendering the running gesture information associated with the corresponding running position point to the three-dimensional virtual model, and generating a running animation.
In this embodiment, a three-dimensional virtual model may be previously established for each vehicle managed by the background management system, and the established three-dimensional virtual model may be stored in a corresponding three-dimensional model storage list, for example, a three-dimensional vehicle model storage list and a three-dimensional aircraft model storage list may be established, where the three-dimensional vehicle model storage list is used for storing each three-dimensional vehicle model, and the three-dimensional aircraft model storage list is used for storing each three-dimensional aircraft model. In a specific embodiment, the three-dimensional vehicle model may be as shown in FIG. 4 and the three-dimensional aircraft model may be as shown in FIG. 5.
In a specific embodiment, the built three-dimensional virtual model may include the following logical components:
Arrow component (MovingDirection): a forward direction toward the model for determining where to be "forward";
rotation center assembly (RotateCenter): judging where the lens should rotate around the model after focusing occurs;
label assembly (Widget): displaying the name of the model, and performing one-step operation on the model by clicking;
GPS position marker component (GPSMArker): the GPS module of the aircraft is positioned at the aircraft nose instead of the center of the aircraft, so that the model is displayed to be integrally forward without GPS correction, and the larger the model is, the larger the error is;
a play management component (VehicleLayer) that drives model animation: when the model is created, the model is initialized once, the basic model only initializes a data queue, a tag and a light switch, if the model is an aircraft, the aircraft also performs primary altitude monitoring for initializing animation data, and the default data queue of a preset frame (such as 10 frames) is stored for animation calculation;
in addition, for the corresponding three-dimensional virtual model of the aircraft, a ground tracker component (groundtracker) is further included, wherein the component is used for judging the altitude, sending event notification when the altitude changes, and starting ray detection when approaching the ground to find the ground position in the real-time scene.
After the driving path is created, the driving path and the three-dimensional virtual model corresponding to the target vehicle in the three-dimensional model storage list can be associated, the three-dimensional virtual model corresponding to the target vehicle can be obtained from the three-dimensional model storage list during control, and the three-dimensional virtual model is controlled to sequentially drive through each driving position point on the driving path according to the driving gesture information in a real-time scene of the user interface. For example, when the target vehicle is an airplane and the corresponding running gesture information is landing gear and flap when the target vehicle runs to a certain running position point, the landing gear and flap effect is generated when the corresponding three-dimensional virtual model of the airplane is controlled to run to the running position point, for example, when the corresponding running gesture information is a deceleration baffle opening when the target vehicle runs to the certain running position point, the deceleration baffle opening effect is generated when the three-dimensional virtual model is controlled to run to the running position point, and therefore, the animation effect is generated through the control of the three-dimensional virtual model, and the reduction of the running path and the running gesture of the target vehicle is realized. In a specific embodiment, the generated driving animation includes a vehicle driving animation and an aircraft driving animation, wherein the vehicle driving animation can be as shown in fig. 6, and the tire rotation speed, the steering trend, the vehicle body inclination angle, the engine state and the like in the driving process of the vehicle can be restored in real time; the running animation of the aircraft can be shown as in fig. 7, and the turbine rotation speed, attitude angle, steering of a rudder, deflection angle of a tail wing, retraction state of a landing gear, retraction state of a flap, retraction state of a speed reducing plate and the like in the running process of the aircraft can be restored in real time.
In addition, after the running animation is generated, the play of the running animation may be controlled according to the operation of the user. For example, the playing, stopping, fast-forwarding or fast-rewinding of the running animation can be controlled according to the playing, pause, fast-forwarding, fast-rewinding and other instructions triggered by the user.
Step 210, determining the animation updating frequency according to the distance between the target vehicle and the preset lens.
The running animation generated in step 209 is obtained from the running parameter information of all the running position points that the target vehicle has currently generated, and since the target vehicle is still running and new running parameter information of the running position points is also generated, the running animation needs to be updated.
In one embodiment, the running animation may be updated according to the update frequency of the running parameter information of the new running position point (i.e., the frequency at which the target vehicle collects real-time running data), i.e., once the running parameter information of the new running position point is generated, the running animation is updated once.
In another embodiment, when updating, the distance between the target vehicle and a preset lens (such as a panoramic lens of an airport) can be determined first, the animation updating frequency is determined according to the distance, and the running parameter information of the next running position point of the target vehicle is obtained from the running information storage list according to the animation updating frequency. Generally speaking, when the distance between the target vehicle and the preset lens is long, a low animation update frequency may be set, when the distance between the target vehicle and the preset lens is short, a high animation update frequency may be set, a specific frequency may be set according to actual requirements, after the animation update frequency is determined, a time for acquiring the running parameter information of the next running position point from the running information storage list may be determined according to the animation update frequency, for example, the animation update frequency may be 60 frames/second, then the running parameter information of the next running position point may be acquired from the running information storage list at a time interval of 1/60 (about 0.017) seconds, for example, the running parameter information acquisition time of the current position point is 2020-05-27:11:00:00.000, and then the running parameter information acquisition time of the next running position point is 2020-05-27:11:00:00.017.
Step 211, updating the running animation according to the animation updating frequency.
After the running parameter information of the next running position point is acquired, the next running position point can be added on the original running path, the running posture information of the target vehicle at the next running position point is determined according to the running parameter information of the next running position point, the three-dimensional virtual model is controlled to run to the next running position point of the running path, and running is carried out on the next running position point according to the corresponding running posture information, so that updating of running animation is realized.
For example, when the target vehicle is a vehicle, the running animation update flow may update the tire rotation speed, the steering wheel yaw angle, the vehicle body side-to-side inclination angle, and the vehicle body front-to-rear inclination angle of the vehicle after reading the running posture information of the next running position point as shown in fig. 8.
When the target vehicle is an aircraft, the running animation updating flow may be as shown in fig. 9, and after the running gesture information of the next running position point is read, the turbine rotation speed, the retraction state of the landing gear, the retraction state of the flap, the opening and closing state of the speed reducing plate, the steering direction of the rudder, and the deflection angle of the tail wing of the aircraft may be updated.
Step 212, receiving a view instruction triggered by a user.
The user can click, slide and other operations on the user interface by using the mouse/finger to trigger the viewing instruction so as to switch the display view angle and the size of the three-dimensional virtual model.
And step 213, adjusting the display view angle and size of the three-dimensional virtual model in response to the viewing instruction.
For example, the three-dimensional virtual model is rotated and scaled according to the view instruction, and the real-time scene of the three-dimensional virtual model is correspondingly rotated and scaled.
It should be noted that the sequence of the steps shown in fig. 2 is merely illustrative, and does not limit the actual execution sequence, and in practice, the execution sequence of some of the steps may be adjusted according to needs, for example, step 207 may also be performed before step 206.
The model and animation effects shown in fig. 4, 5, 6, and 7 are also merely examples, and do not constitute final limitations on the style and presentation effect of the actual model.
In addition, in this embodiment, a thumbnail of the driving status of each vehicle managed by the background management system may be displayed for the user on the user interface, in the thumbnail, the three-dimensional virtual model corresponding to each vehicle may travel on the corresponding driving path according to the corresponding driving gesture information in a small image, and meanwhile, the identification information (such as license plate number/flight number) of the corresponding vehicle and the driving parameter information (such as position information, altitude information, direction information, speed information, etc.) of the corresponding vehicle may be displayed on the three-dimensional virtual model for the user to view, and if the user clicks to focus on a certain three-dimensional virtual model, the three-dimensional virtual model may be focused on the user interface and the driving process of the three-dimensional virtual model may be tracked.
In order to optimize the storage space and save processing resources, the updating condition of the running parameter information of each vehicle can be monitored, for example, as shown in fig. 10, a timer can be set to trigger to check the updating condition of the running parameter information of each vehicle at regular time, if the vehicle is an aircraft, the data receiving time of the last time data received from the server in the aircraft running information storage list can be checked, if it is known that a certain aircraft has no new running parameter information added beyond a first preset duration according to the receiving time, the engine animation effect of the three-dimensional virtual model corresponding to the aircraft displayed on the user interface can be closed, if the aircraft has no new running parameter information added beyond a second preset duration in the running information storage list, the running animation of the three-dimensional virtual model corresponding to the aircraft displayed on the user interface can be removed, and the running parameter information corresponding to the aircraft in the running information storage list can be deleted, and the three-dimensional virtual model corresponding to the aircraft in the three-dimensional model storage list can be deleted, wherein the first preset duration is smaller than a second preset duration, for example, the second preset duration is longer than 2 minutes, and the second preset duration is longer than 20 minutes. When the vehicle is a vehicle, the processing method is the same as that of the aircraft, and will not be described here again.
The processing procedure of the background management system on the real-time running data received from the server is described below with reference to a specific flowchart, as shown in fig. 11, after the background management system receives the real-time running data from the server, it will determine whether the real-time running data belongs to a vehicle or an aircraft, if the real-time running data belongs to the vehicle, the data is preprocessed and then stored in a vehicle running information storage list and the data receiving time is recorded, and if the data belongs to the aircraft, the data is preprocessed and then stored in the aircraft running information storage list and the data receiving time is recorded. Aiming at the data stored in the running information storage list of the aircraft currently, the background management system judges whether a three-dimensional aircraft model corresponding to the aircraft is displayed in a real-time scene or not, if the model is displayed in the real-time scene, a running position point is newly added in a running path according to the currently stored data, the running gesture information of the running position point is determined, and then a running animation is updated according to the newly added running position point and the running gesture information; if the model is not displayed in the real-time scene, a running path is created according to the data in the running information storage list of the aircraft, the running gesture information is determined, then a three-dimensional aircraft model corresponding to the aircraft is established, the buffer time is set, and the three-dimensional aircraft model is controlled to run on the running path according to the running gesture information, so that a running animation is generated. The processing method is the same as the processing method of the data in the vehicle running information storage list aiming at the data stored in the vehicle running information storage list currently.
