Description

Technical Field

[0001] The present invention belongs to the field of virtual reality technology, and in particular relates to a gun barrel overheating reminder method, system, readable storage medium and device. Background Art

[0002] With the development of social economy, virtual reality technology has been widely used in various fields and has been recognized by more and more people. Users can experience the most realistic feelings in the virtual reality world. The authenticity of the simulated environment is difficult to distinguish from the real world, giving people an immersive feeling. At the same time, it has a super simulation system that truly realizes human-computer interaction, allowing people to operate at will and get the most realistic feedback from the environment during the operation. This technology has the characteristics of realism and human-computer interaction. If combined with military exercises, the value it brings is immeasurable.

[0003] In the simulation training that combines traditional military drills with virtual reality technology, infantry machine gun barrels, tank gun barrels, armored vehicle barrels and other gun barrels are not subject to any restrictions on use, that is, the guns can be used normally for a long time in any environment. In actual use, guns will be affected by the barrel material, weather, temperature and shooting time. For example, when the temperature is high and the gun is shooting for a long time, the barrel will heat up seriously and cannot shoot normally. If simulation training is carried out in this wrong way for a long time, it will inevitably mislead the soldiers to a certain extent, thereby greatly reducing the training effect.

[0052] Embodiment 1

[0053] See also Figure 1 , Figure 1 A barrel overheating reminder method provided by the first embodiment of the present invention is shown, and the method specifically includes steps S01 to S09.

[0054] Step S01, obtaining a VR real-scene model of a training venue, wherein the VR real-scene model of the training venue at least includes a physical three-dimensional model of the training venue.

[0055] It can be understood that the physical three-dimensional model of the training ground may include mountains, rivers, trees, targets and various buildings, and the VR real-scene model of the training ground also includes a weather model. The weather model includes various weather conditions, such as sunny, cloudy, rainy, snowy, etc. The physical three-dimensional model of the training ground and the weather model can be set according to the actual exercise environment to establish a training scene that conforms to the actual situation.

[0056] Among them, when users obtain the VR real-scene model and weather model of the training site, they will have an intuitive feeling. Through VR technology, users will have an immersive feeling, thereby achieving better training results.

[0057] Step S02, obtaining a three-dimensional solid model of a gun barrel in the three-dimensional solid model of the training ground, wherein the three-dimensional solid model of the gun barrel at least includes gun barrel material data.

[0058] Among them, when the physical three-dimensional model of the training ground is established, it will be associated with the physical three-dimensional model of the gun barrel, that is, the physical three-dimensional model of the gun barrel can complete the behavior in the physical three-dimensional model of the training ground. In this embodiment, the established VR real-scene model of the training ground includes the physical three-dimensional model of the armored vehicle training ground and the environmental three-dimensional model within a preset distance range around the armored vehicle training ground. It can be understood that if the combat on the island is simulated, the physical three-dimensional model of the armored vehicle training ground will be designed according to the actual island situation, and the environmental three-dimensional model within the preset distance range around the armored vehicle training ground can be the ocean, other islands, warships, etc., which can be designed according to actual conditions. It should be noted that the armored vehicle cannot enter the environmental three-dimensional model within the preset distance range around the armored vehicle training ground. Among them, the physical three-dimensional model of the armored vehicle training ground includes the physical three-dimensional models of various training equipment in the armored vehicle training ground, such as targets, obstacles, and other armored vehicles.

[0059] Specifically, the barrel entity three-dimensional model is a machine gun barrel arranged on an armored vehicle, and its appearance is consistent with the machine gun arranged on an actual armored vehicle. The barrel entity three-dimensional model includes at least data on the barrel material and the barrel heating state. It can be understood that depending on the barrel material, the rate of increase of the barrel temperature during continuous shooting is also different, that is, there is a difference in the temperature change rate. The barrel material can be simulated as the state of the material used for the actual barrel, which is generally high-alloy chromium-molybdenum steel, stainless steel and other materials. The barrel heating state can be indicated by different colors. For example, when the barrel is overheated, the barrel heating state is an overheated state, and the barrel can be displayed as dark red; when the barrel is heated, the barrel heating state is a heated state, which can be displayed as light red; when the barrel is not heated, the barrel heating state is a non-heated state, which can be displayed as the original color of the barrel.

[0060] In this embodiment, a barrel material mapping model is pre-established. The barrel material mapping model is used to input barrel material data and output a temperature change rate corresponding to the barrel material data. When the trainee enters the VR system, he needs to select a machine gun. When the machine gun is selected and ready to start training, the barrel material corresponding to the machine gun is determined. After the barrel material is determined, the barrel material data is input into the barrel material mapping model to obtain the corresponding temperature change rate.

[0061] In addition, the weather model includes natural weather conditions such as sunny, cloudy, rainy, snowy, and windy. In an actual battlefield, weather changes are also one of the key factors affecting changes in the battle situation. Therefore, in this embodiment, an association between the VR real-scene model of the training ground, the three-dimensional model of the gun barrel entity, and the weather model is established, that is, the display of the three-dimensional model of the gun barrel entity in the VR real-scene model of the training ground under different weather conditions. For example, the machine gun barrel arranged on the armored vehicle is brighter on a sunny day, and there will be reflective points depending on the angle, while on rainy days, the appearance is darker; when the machine gun barrel arranged on the armored vehicle moves on rainy and snowy days, raindrops or snowflakes will fall on the machine gun barrel, and at the same time, raindrops or snowflakes will come towards the machine gun barrel during the movement; after firing a bullet / shell and hitting the target, the target will be damaged; when the armored vehicle collides with an obstacle, it will stop moving, etc.

[0062] Step S03, obtaining the first temperature value of the current three-dimensional model of the gun barrel entity, and determining whether the current three-dimensional model of the gun barrel entity is in a shooting state, if so, executing step S04; if not, executing step S09.

[0063] It should be noted that the first temperature value of the current gun barrel physical three-dimensional model, that is, the starting temperature of the gun barrel physical three-dimensional model before shooting, is obtained, and the first temperature value changes in real time. It can be understood that the first temperature value will not be lower than the air temperature value in the physical three-dimensional model of the training ground. Specifically, when the gun barrel physical three-dimensional model is placed in the training ground VR real-scene model, specific coordinates will be generated. It can be understood that the training ground VR real-scene model is also a three-dimensional model composed of several coordinates. After the position coordinates of the gun barrel physical three-dimensional model in the training ground VR real-scene model are obtained, the air temperature value of the position coordinates is read. If it is determined that the gun barrel physical three-dimensional model has never been in a shooting state after the VR system is started, the air temperature value in the physical three-dimensional model of the training ground is set to the first temperature value.

[0064] Furthermore, the shooting state can be single shot, continuous shooting, etc. When the barrel entity three-dimensional model is in the shooting state, the barrel entity three-dimensional model will be dynamically updated along with the shooting, and the occurrence of the shooting state is related to the input of the shooting command. The input of the shooting command can be completed by operating an external VR device. The VR device can be made consistent with the appearance of the machine gun arranged on the actual armored vehicle to achieve better training effects.

[0065] In step S04, it is determined whether the shooting state is in a continuous shooting state, and if so, step S05 is executed.

[0066] It can be understood that the continuous shooting state refers to the continuous firing of bullets / shells for a period of time, rather than a single shooting, that is, the continuous input of shooting commands. According to actual conditions, it can be known that only when the gun is in a continuous shooting state, the barrel is likely to overheat. When the gun is firing at a single point, there is a certain cooling time between the firing of bullets / shells, and the barrel is not prone to overheating.

[0067] Therein, a continuous shooting time threshold needs to be preset, that is, when the continuous input time of the shooting command is greater than or equal to the preset continuous shooting time threshold, it is determined to be in a continuous shooting state.

[0068] Step S05, obtaining the continuous shooting time when the shooting state is in the continuous shooting state, and determining the temperature change rate of the corresponding gun barrel entity model according to the gun barrel material data.

[0069] It should be noted that the continuous shooting time is the time when bullets are continuously fired, not the time when shooting commands are continuously input. When there are sufficient bullets, the continuous shooting time is the time when shooting commands are continuously input. When all bullets are fired, the continuous shooting time is the time from the start of shooting command input to the time when all bullets are fired.

[0070] Step S06, determining a second temperature value of the three-dimensional model of the gun barrel entity according to the continuous shooting time, the first temperature value and the temperature change rate.

[0071] Specifically, the formula for calculating the second temperature value is:

[0072] y = ax + b;

[0073] Among them, y represents the second temperature value, x represents the continuous shooting time, a represents the temperature change rate, and b represents the first temperature value. It can be found that the relationship between the second temperature value and the continuous shooting time in the formula is a linear relationship, that is, the ambient temperature does not affect the heating rate of the barrel under continuous shooting, which is consistent with the actual situation.

[0074] Step S07, determining whether the second temperature value is greater than or equal to a preset temperature value, if so, executing step S08.

[0075] Step S08: a prompt message is issued, wherein the prompt message is used to warn the trainee that the gun barrel is overheated.

[0076] Specifically, when the second temperature value is greater than or equal to the preset temperature value, the color of the gun barrel is displayed as soldering iron red. At this time, shooting will not be possible, and a prompt message will be issued, such as using audio broadcast: this gun is overheated and cannot continue to shoot, etc. Among them, the color of the gun barrel as soldering iron red itself also serves a certain warning role.

[0077] By way of example and not limitation, in some other embodiments, the effects of the gun barrel heating and overheating can be added as needed. For example, the main color of the gun barrel gradient is orange; the gun barrel overheating state is warned by flashing red text, etc.

[0078] Step S09, calculating a third temperature value of the barrel solid three-dimensional model after the cooling time according to the first temperature value, the total temperature drop rate and the cooling time.

[0079] Specifically, when the first temperature value is the air temperature value, cooling is not required. It can be understood that the third temperature value is also the air temperature value. It should be noted that in actual combat, in order to ensure firepower while preventing the barrel from overheating and being unable to shoot, soldiers usually control continuous shooting for a period of time to allow the barrel to cool down properly, and then continue shooting, and repeat this process to achieve a high level of combat. If the cooling time is insufficient, the barrel will easily overheat if shooting is continued again.

[0080] In this embodiment, the VR real scene model of the training site also includes weather status data, which includes at least wind speed sub-data and rainfall sub-data. According to the wind speed sub-data and the rainfall sub-data, corresponding wind speed mapping models and rainfall mapping models are respectively established. The wind speed mapping model is used to input the wind speed sub-data and output the first cooling rate corresponding to the wind speed sub-data. The rainfall mapping model is used to input the rainfall sub-data and output the second cooling rate corresponding to the rainfall sub-data.

[0081] According to the first cooling rate and the second cooling rate, the total cooling rate is calculated, and the calculation formula is:

[0082] γ=k1α+k2β+ω

[0083] Among them, γ represents the total cooling rate, α represents the first cooling rate, β represents the second cooling rate, k1 represents the first weight coefficient of the first cooling rate, k2 represents the second weight coefficient of the second cooling rate, ω represents the first correction coefficient. Specifically, under the influence of wind speed and rainfall factors, the cooling rate of the barrel is different from the natural static cooling rate. The greater the wind speed, the greater the barrel cooling rate, and the greater the rainfall, the greater the barrel cooling rate. The weather state can be customized in the VR system, which can be specifically the wind force level and rainfall level in different time periods, that is, wind speed sub-data and rainfall sub-data, and then the wind speed mapping model and rainfall mapping model are respectively input according to the wind force level and rainfall level to obtain the corresponding cooling rate.

[0084] When the total cooling rate is calculated, the third temperature value of the barrel solid three-dimensional model after the cooling time is calculated according to the first temperature value, the total cooling rate and the cooling time. The calculation formula is:

[0085] z = bt*γ;

[0086] Among them, z represents the third temperature value, b represents the first temperature value, t represents the cooling time of the barrel solid three-dimensional model when it is not in the shooting state, γ represents the total cooling rate, and then the third temperature value is assigned to the first temperature value, and is updated in real time, which can be displayed on the VR display.

[0087] In summary, the gun barrel overheating reminder method in the above embodiment of the present invention obtains a VR real-scene model of a training ground and a three-dimensional model of a gun barrel entity, wherein the VR real-scene model of the training ground at least includes the three-dimensional model of the training ground entity, and the three-dimensional model of the gun barrel entity includes at least the material data of the gun barrel. Specifically, after determining that the three-dimensional model of the gun barrel entity is in a shooting state, it continues to determine whether the shooting state is in a continuous shooting state, because only in the continuous shooting state will the gun barrel overheat, and then the continuous shooting time when the shooting state is in the continuous shooting state is obtained, and the temperature change rate of the corresponding gun barrel entity model is determined according to the gun barrel material data, and the second temperature value of the three-dimensional model of the gun barrel entity is determined according to the continuous shooting time, the first temperature value and the temperature change rate, and when it is determined that the second temperature value is greater than or equal to the preset temperature value, a prompt message will be issued, indicating that the gun is overloaded, and the gun will no longer be able to shoot for a period of time, simulating a real gun overheating situation, which is more in line with the actual situation, thereby achieving a training effect.
