Obviously, the following drawings are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0031] Figure 1 It is a schematic diagram of the working steps of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0033] In many scenarios, it is very necessary to simulate the motion trajectory of moving elements. The prior art (a patent application for invention with the literature number CN105957120B) determines the motion trajectory of moving elements by preset curve formulas and motion trajectory setting parameters, making the motion trajectory more in line with objective laws; the prior art directly sets the parameters of moving elements through software, but cannot import the moving elements in the actual scenario, resulting in the inconsistency between the moving elements and those in the actual scenario; during the trajectory simulation process, the calculation is complex, and many parameters and conditions need to be set, resulting in low trajectory simulation efficiency and simulation accuracy.

[0034] The present invention obtains basic data through a data parsing module, then parses and obtains element basic parameters, and then combines the element basic parameters with a trajectory simulation model to perform segmented simulation of the motion trajectory, which can expand the application scenario and improve the efficiency and accuracy of trajectory simulation.

[0035] Please refer to Figure 1 , an embodiment of the first aspect of the present application provides a motion trajectory simulation control and analysis system, including a data parsing module, a trajectory simulation module, and a trajectory display module, and the trajectory simulation module is respectively connected to the data parsing module and the trajectory display module;

[0036] Data parsing module: Parse and obtain element basic parameters according to the basic data, and send the element basic parameters to the trajectory simulation module;

[0037] Trajectory simulation module: Combine the trajectory simulation model and the element basic parameters, and perform segmented simulation of the motion trajectory in combination with the initial position of the moving element;

[0038] Trajectory display module: Connected to a number of OLED display units, and splice and display the segmented simulation results through the number of OLED display units.

[0039] In the present application, the trajectory simulation module is respectively communicatively and / or electrically connected to the data parsing module and the trajectory display module.

[0040] The element basic parameters in the present application include characteristic parameters of moving elements such as the size, speed, acceleration, and speed limit of the moving element. The initial state of the moving element can be obtained through the element basic parameters; it can be understood that the element basic parameters also include limiting conditions for the moving element to facilitate the construction of constraint conditions.

[0041] The trajectory simulation model in the present application includes trajectory prediction algorithms such as deep convolutional neural network algorithms, particle swarm algorithms, and ant colony algorithms. It can be understood that the moving elements in the present application are similar to vehicles in autonomous driving, so the relevant algorithms in autonomous driving can be analogously referenced.

[0042] The OLED display unit in this application is specifically an OLED screen; it should be noted that the number of OLED display units does not necessarily equal the number of segments in the segmented simulation of the motion trajectory.

[0043] The data parsing module in this application obtains basic data through a smart terminal or an image acquisition device; the image acquisition device includes a camera and a smartphone, and the smart terminal includes a smartphone, a tablet computer, and a laptop computer; it can be understood that the image acquisition device is mainly used to collect video data, and a hardware device, a server, etc. storing video data can also be understood as an image acquisition device.

[0044] In an alternative embodiment, the data analysis module obtains basic data through a smart terminal.

[0045] The main object in this embodiment is a motion element in a virtual scene, such as a football in animation design, and the basic data of the motion element is directly input through a smartphone, etc. It can be understood that when directly inputting basic data through a smart terminal, the essence of parsing and obtaining the basic parameters of the element from the basic data is the conversion between data.

[0046] In an alternative embodiment, the data parsing module obtains the basic parameters of the element through an image acquisition device, including:

[0047] Obtain and verify video data through an image acquisition device;

[0048] Extract the motion element and the corresponding basic parameters of the element from the video data.

[0049] The main object in this embodiment is a motion element in a real scene, such as a basketball on a court. The basic data of the motion element is obtained through an image acquisition device, and then the corresponding basic parameters of the element are parsed and obtained. It can be understood that the parsing and obtaining in this embodiment refers to extracting the basic parameters of the element from the video data, that is, calculating data such as speed and size by comparing multiple frames of images in the video data.

[0050] It should be noted that the video data can be obtained in real time or recorded, making the application scope of this application wider.

[0051] In an embodiment, the trajectory simulation module performs segmented simulation of the motion trajectory according to the initial position, including:

[0052] Construct a trajectory simulation model according to the basic parameters of the element, the initial position, and the constraint conditions;

[0053] Run the trajectory simulation model and perform segmented simulation of the running trajectory according to time or distance.

[0054] In this embodiment, when constructing the trajectory simulation model, it is necessary to establish constraint conditions, such as speed limits, acceleration limits, communicable areas, etc., to ensure that the simulated trajectory obtained through the trajectory simulation model conforms to the actual situation.

[0055] In this embodiment, the motion trajectory is segmented and simulated according to time or distance; for example, starting from the initial position, based on the basic element parameters of the motion element, the simulated trajectory of the motion element is obtained at regular intervals until the required trajectory is obtained; or the corresponding simulated trajectory is obtained every time the motion element moves a fixed length until the simulation is completed.

[0056] It should be noted that in this embodiment, there is no set target position, but there is an initial position, that is, the position where the motion element will arrive is simulated and predicted according to the initial state of the motion element, which can be applied to the trajectory simulation of motion elements without other driving forces (gravity, etc. do not belong to other driving forces) during the motion process.

[0057] In an alternative embodiment, the trajectory simulation module performs segmented simulation of the motion trajectory according to the initial position and the target position, including:

[0058] Obtain a preset curve according to the initial position and the target position;

[0059] Select a number of control points on the preset curve, and the curve between any two adjacent control points is used as a simulation segment;

[0060] Run the trajectory simulation model to simulate the motion trajectory of the motion element in each simulation segment and obtain the segmented simulation result.

[0061] The control points in this embodiment include the initial position and the target position, that is, the total number of control points is greater than 2.

[0062] In this embodiment, a target position is set, and a preset curve is set according to the initial position and the target position. It can be understood that the preset curve includes straight lines, broken lines, arcs, etc.; control points are selected on the preset curve, and then simulation segments are obtained, and the simulated trajectories of the simulation segments are obtained, thereby realizing trajectory simulation.

[0063] It should be noted that this embodiment can be applied to scenarios where the driving force of the motion element can be changed during the motion process, such as the flight process of an unmanned aerial vehicle. By simulating the trajectory to control the power output of the unmanned aerial vehicle, it helps to reduce energy consumption.

[0064] In this embodiment, the curve lengths of several simulation segments are the same, or the curve lengths of several simulation segments form a geometric sequence.

[0065] The construction of the trajectory simulation algorithm and the trajectory simulation according to the trajectory simulation algorithm can refer to the papers "Research on Vehicle Trajectory Prediction and Illegal Right-Turn Behavior Warning at Intersections", "Research on Pedestrian Tracking and Trajectory Prediction in Urban Roads Based on Deep Learning" and other related existing technologies.

[0066] The construction and acquisition of constraint conditions can refer to the paper "Ship Trajectory Prediction under Channel Constraint Conditions Based on Marine Big Data" and other existing technologies related to the construction of constraint conditions.

[0067] In one embodiment, the trajectory display module performs communication verification on a number of OLED display units, including:

[0068] Mark the OLED display units called by the trajectory display module as target display units;

[0069] Send a verification instruction to the target display unit through the trajectory display module;

[0070] When the trajectory display module receives the response signal from the target display unit within the specified time, it is determined that the communication of the target display unit is normal.

[0071] The main purpose of this embodiment is to perform communication verification on the OLED display units, which can perform synchronous verification on all OLED display units or separately verify the OLED display units to ensure the display effect of the motion trajectory.

[0072] In a specific embodiment, the number of times of sending verification instructions to the same target display unit for each communication verification does not exceed 3 times, and the time interval between adjacent verification instructions sent is not less than 0.5 seconds.

[0073] Some of the data in the above formula are calculated by removing the dimension and taking their numerical values. The formula is the one that is closest to the real situation obtained through software simulation of a large amount of collected data; the preset parameters and preset thresholds in the formula are set by those skilled in the art according to the actual situation or obtained through simulation of a large amount of data.

[0074] The working principle of the present invention:

[0075] The data parsing module parses and obtains the element basic parameters according to the basic data, and sends the element basic parameters to the trajectory simulation module.

[0076] The trajectory simulation module constructs a trajectory simulation model and performs segmented simulation on the motion trajectory of the motion elements in combination with the element basic parameters.

[0077] After the trajectory display module performs communication verification on a number of OLED display units, it splices and displays the segmented simulation results.

[0078] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
