[0002] With the rapid development of infrared technology, infrared imaging systems have played an important role in many fields. In the research process of infrared equipment, the parameters of the equipment often need to be adjusted to achieve the best imaging effect, but these adjustments often need to be made through long-term field experiments, which will consume a lot of manpower and material resources. In addition, due to the uncontrollable environmental conditions of the field, sometimes the field experiments cannot obtain the required data, resulting in huge economic losses. Therefore, infrared imaging simulation technology has emerged as the times require. The prior art can accurately set the parameters of the experimental environment through infrared imaging simulation technology, thereby simulating the infrared imaging effect in a specific or extreme environment, greatly reducing the cost required for field experiments; in addition, mature infrared simulation technology can also be used for testing new models of infrared imaging equipment, which can also save a lot of time and economic cost. Therefore, the research on infrared simulation technology has important economic significance for the application of infrared technology, which can greatly shorten the development cycle of the equipment and thus reduce the development cost of the equipment.

[0003] In order to simulate the real infrared imaging as much as possible, the existing traditional infrared simulation technology needs to collect infrared image data of various materials, calculate the corresponding infrared image of each material according to the infrared radiation model, establish an image database with these images, and then model the target object and use the infrared image data in the database for rendering to simulate the overall infrared characteristics of the target object under different environmental temperatures, atmospheric radiation and solar radiation.

In addition, the existing infrared simulation technology mainly simulates images of single scene and single object, and cannot meet the infrared simulation requirements of multiple objects coexisting in a complex environment. Moreover, the existing infrared simulation uses a large number of shaders and repeatedly loads them during rendering, and there is a problem of using high-precision maps consistent with the visible light scene in the infrared scene, which leads to a large consumption of processors and thus a high requirement for computer performance, thereby increasing the cost of infrared simulation.

On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can be present.

The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0048] The prior art infrared simulation technology is mostly only for single frame image simulation, which cannot meet the modern real-time simulation demand. In addition, the existing infrared simulation technology mainly simulates images of single scene and single object, and cannot meet the infrared simulation demand of multiple objects coexisting in complex environment. Moreover, the existing infrared simulation uses a large number of shaders and repeatedly loads during rendering, and there is a problem of using high-precision maps consistent with the visible light scene in the infrared scene, which causes large consumption of the processor and high requirement for computer performance, thereby increasing the cost of infrared simulation.

[0049] Please refer to Figure 1 , which is an infrared simulation method provided by the first embodiment of the application. The infrared simulation method provided by the embodiment can significantly reduce the number of shaders used, and can eliminate the preloading of shaders. In addition, two sets of maps are used in the visible light and infrared scenes, which can significantly reduce the consumption of the processor, thereby reducing the requirement for computer performance and the cost of infrared simulation.

[0050] Specifically, the infrared simulation method provided by the embodiment specifically includes the following steps:

[0051] Step S10, input each object in the target scene into the terrain editor respectively, and input the scene information corresponding to the target scene in the terrain editor through a first preset script to obtain the solar radiation intensity and the atmospheric attenuation coefficient corresponding to the target scene.

[0052] Specifically, in the embodiment, first of all, it needs to be pointed out that the infrared simulation method provided by the embodiment is specifically applied in the field of scene simulation technology. Further, the infrared simulation method provided by the embodiment is implemented based on the shader and the terrain editor set in the background, which can effectively reduce the consumption of the processor and the cost of infrared simulation.

[0053] Therefore, in this step, it should be noted that when the target scene to be simulated by infrared is obtained, the objects present in the target scene are first identified. Simultaneously, a target 3D model corresponding to each of the objects is constructed using pre-set 3D software, and the constructed target 3D model is then input into the terrain editor in real time. Preferably, in this embodiment, the target scene provided by this embodiment can be a scene such as the sky, a city, trees, or a lake, all of which fall within the scope of this embodiment.

[0054] Furthermore, this embodiment will further input scene information corresponding to the current target scene in real time in the current terrain editor through a pre-set first preset script, so as to obtain the solar radiation intensity and atmospheric attenuation coefficient corresponding to the current target scene. Specifically, the scene information provided by this embodiment includes latitude and longitude, time, weather and other information.

[0055] Step S20, calculating the solar radiation angle corresponding to the target scene through the first preset script, and constructing a corresponding atmospheric radiation transmission model based on the solar radiation angle, solar radiation intensity, and atmospheric attenuation coefficient, so as to calculate the first surface radiation intensity of each of the object surfaces according to the atmospheric radiation transmission model;

[0056] Furthermore, in this embodiment, it should be noted that after obtaining the required solar radiation intensity and atmospheric attenuation coefficient through the above steps, this step will further calculate the solar radiation angle corresponding to the current target scene through the above-mentioned first preset script. At the same time, a corresponding atmospheric radiation transmission model is constructed based on the current solar radiation angle, solar radiation intensity, and atmospheric attenuation coefficient. On this basis, the first surface radiation intensity corresponding to each object surface in the current target scene is further calculated through the atmospheric radiation transmission model. Preferably, the first preset script provided in this embodiment is set to the SunIntensity (solar radiation simulation) script.

[0057] Step S30, based on the first surface radiation intensity, calculating the target radiation intensity of each of the objects mapped to the target virtual imaging device using a second preset script, and gray-scaling the target radiation intensity using a third preset script;

[0058] Specifically, in the embodiment, it is to be noted that after the first surface radiation intensity of each object is further obtained through the above steps, the current target radiation intensity of each object mapped to the target virtual imaging device is calculated through the second preset script set in advance, and the current target radiation intensity is further subjected to corresponding gray processing through the third preset script set in advance, wherein it is to be noted that the higher the value of the target radiation intensity of the object mapped to the target virtual imaging device, the darker the corresponding gray color. Preferably, the second preset script provided in the embodiment is set as an AirIntensity (atmospheric radiation transmission simulation) script.

[0059] In step S40, the gray color corresponding to each object is displayed in the display screen of the target virtual imaging device, and the display screen is dynamically and real-timely displayed to complete the infrared simulation of the target scene.

[0060] Finally, in the step, it is to be noted that the gray color corresponding to each object is further displayed in the display screen of the target virtual imaging device in real time, and at the same time, the current display screen is dynamically and real-timely displayed to finally complete the infrared simulation of the current target scene.

[0061] In use, the target three-dimensional model corresponding to each object in the target scene is input into the terrain editor, and the scene information corresponding to the target scene is input into the terrain editor through the first preset script to obtain the solar radiation intensity and the atmospheric attenuation coefficient corresponding to the target scene. Further, the solar radiation angle corresponding to the target scene is calculated through the first preset script, and the corresponding atmospheric radiation transmission model is constructed according to the solar radiation angle, the solar radiation intensity and the atmospheric attenuation coefficient, so as to calculate the first surface radiation intensity of the surface of each object according to the atmospheric radiation transmission model. On this basis, the target radiation intensity of each object mapped to the target virtual imaging device is calculated through the second preset script based on the first surface radiation intensity, and the target radiation intensity is subjected to gray processing through the third preset script. Finally, the gray color corresponding to each object can be displayed in the display screen of the target virtual imaging device, and the display screen is dynamically and real-timely displayed to complete the infrared simulation of the target scene. Through the above manner, the number of used shaders can be significantly reduced, the preloading of the shaders can be saved, and two sets of maps are used in the visible light and infrared scenes, so that the consumption of the processor can be significantly reduced, and the requirement for the computer performance is reduced, and the cost of the infrared simulation is reduced.

[0062] It should be noted that the above implementation process is only for the purpose of illustrating the feasibility of the present application, but it does not mean that the infrared simulation method of the present application has only the above unique implementation process, on the contrary, as long as the infrared simulation method of the present application can be implemented, it can be included in the feasible implementation scheme of the present application.

[0063] In summary, the infrared simulation method provided by the above embodiments of the present application can significantly reduce the number of shaders used, while eliminating the need for preloading of shaders, and using two sets of maps in visible light and infrared scenes, thereby significantly reducing the consumption of the processor, and reducing the requirement for computer performance, thereby reducing the cost of infrared simulation.

[0064] The second embodiment of the present application also provides an infrared simulation method, and the difference between the infrared simulation method provided by the present embodiment and the infrared simulation method provided by the first embodiment is:

[0065] Specifically, in the present embodiment, it should be noted that the above step of inputting each object in the target scene corresponding to the target three-dimensional model into the terrain editor includes:

[0066] When the target scene is determined, each object appearing in the target scene is detected based on a preset recognition algorithm, and a target three-dimensional model corresponding to each object is respectively constructed through a preset program;

[0067] The target three-dimensional model is input into the terrain editor, and a map shader corresponding to the target three-dimensional model is selected in the terrain editor, so as to add a corresponding map to the target three-dimensional model through the map shader.

[0068] Specifically, in the present embodiment, it should be noted that when the present embodiment determines the required target scene, the present embodiment will immediately detect each object appearing in the current target scene through a preset recognition algorithm, and at the same time, a target three-dimensional model corresponding to each object appearing in the current target scene is respectively constructed through a preset program, wherein it should be noted that the present embodiment will detect each object appearing in the current target scene through a pre-set convolutional neural network, and further, the present embodiment will construct a target three-dimensional model corresponding to each object appearing in the current target scene through a pre-set three-dimensional software such as ug and solidworks.

[0069] Further, the embodiment further inputs the target three-dimensional model constructed in real time into the above-mentioned terrain editor, and simultaneously, the embodiment further selects a map shader corresponding to the target three-dimensional model in the current terrain editor, and on this basis, adds a corresponding map to the current target three-dimensional model through the selected map shader. Preferably, in the embodiment, the terrain editor provided by the embodiment is set as a unity3d editor, and in addition, the embodiment selects different map shaders corresponding to the types of objects in real time, wherein it needs to be pointed out that the types of objects provided by the embodiment specifically include an internal heat source type object and a non-internal heat source type object. For example, when the identified object is a car, the corresponding selected map shader is an internal heat source shader infMatHeatIn.

[0070] It needs to be pointed out that the implementation principle and some technical effects generated by the method provided by the second embodiment of the application are the same as those of the first embodiment, and for brief description, the second embodiment is not mentioned in the first embodiment. The corresponding content provided by the first embodiment can be referred to.

[0071] In summary, the infrared simulation method provided by the above-mentioned embodiments of the application can significantly reduce the number of used shaders, and can save the preloading of the shaders, and can use two sets of maps in the visible light and infrared scenes, so as to significantly reduce the consumption of the processor, and further reduce the requirement for the computer performance, and correspondingly reduce the cost of the infrared simulation.

[0072] The third embodiment of the application also provides an infrared simulation method, and the infrared simulation method provided by the embodiment is different from the infrared simulation method provided by the first embodiment in that:

[0073] Specifically, in the embodiment, it also needs to be explained that the step of constructing a corresponding atmospheric radiation transmission model according to the solar radiation angle, the solar radiation intensity and the atmospheric attenuation coefficient to calculate the first surface radiation intensity of each object surface includes:

[0074] When the atmospheric radiation transmission model is acquired, the actual solar radiation intensity and the sky background radiation intensity of the sunlight transmitted into the atmosphere are calculated through the atmospheric radiation transmission model, and a corresponding fourth preset script is added to each object to identify the material type corresponding to each object through the fourth preset script;

[0075] The emissivity corresponding to each object is found in a preset database according to the material type, to construct a corresponding infrared radiation characteristic model, and the first surface radiation intensity of each object surface is calculated according to the solar radiation intensity and the infrared radiation characteristic model.

[0076] Specifically, in the embodiment, it can be understood that the sunlight will be attenuated in the process of transmission, that is, the sunlight will also be attenuated in the process of transmission in the earth's atmosphere, so when the above atmospheric radiation transmission model is acquired, the embodiment will further calculate the actual solar radiation intensity and the corresponding sky background radiation intensity of the sunlight transmitted into the atmosphere through the current atmospheric radiation transmission model. At the same time, a corresponding fourth preset script is added to each object in the current target scene, and the material type corresponding to each object is further identified through the fourth preset script. Preferably, the fourth preset script provided by the embodiment is set as the MaterialTypeCtrl (object radiation calculation) script.

[0077] On this basis, since the radiation reflectivity of different types of objects is different, the embodiment needs to further find out the radiation emissivity corresponding to each object in the preset database through the material type acquired in real time, and construct the required infrared radiation feature model accordingly. On this basis, the first surface radiation intensity of the surface of each object is further calculated according to the above solar radiation intensity and the current infrared radiation feature model.

[0078] It should be pointed out that the method provided by the third embodiment of the present application has the same implementation principle and some technical effects as the first embodiment. For brevity, the unmentioned parts of the embodiment can be referred to the corresponding contents provided by the first embodiment.

[0079] In summary, the infrared simulation method provided by the above embodiments of the present application can significantly reduce the number of shaders used, and can save the preloading of shaders. In addition, two sets of maps are used in the visible light and infrared scenes, so that the consumption of the processor can be significantly reduced, and the requirement for computer performance is reduced, and the cost of infrared simulation is reduced.

[0083] Specifically, in the embodiment, it is to be noted that when the target scene provided by the embodiment contains the sky, it can be understood that the atmosphere also exists in the sky, and thus the embodiment also needs to render the radiation of the atmosphere.

[0084] Specifically, when the actual solar radiation intensity and the sky background radiation intensity are acquired, the third preset script is immediately called, and at the same time, the radiation value of the sky background texture map materializer is modified according to the current actual solar radiation intensity and the sky background radiation intensity through the third preset script, so that the rendering of the atmospheric radiation can be simply and effectively completed. Preferably, the third preset script provided by the embodiment is set as a GrayCal (radiation gray mapping) script.

[0085] It should be pointed out that the method provided by the fourth embodiment of the application has the same implementation principle and some technical effects as the first embodiment, and for brief description, the contents not mentioned in the fourth embodiment can be referred to the corresponding contents provided by the first embodiment.

[0088] Specifically, in the embodiment, it is to be noted that when the target scene provided by the embodiment contains the sky, it can be understood that the atmosphere also exists in the sky, and thus the embodiment also needs to render the radiation of the atmosphere.

[0089] The fifth preset script is added to the internal heat source object, and the internal heat source intensity, the heat source radius and the heat source attenuation coefficient inside the internal heat source object are simulated through the fifth preset script.

[0090] The surface temperature of the internal heat source object is calculated through the sixth preset script, and the second surface radiation intensity corresponding to the internal heat source object is calculated according to the material type of the internal heat source object, the object self-radiation intensity, the solar radiation intensity and the surface temperature, so as to complete the radiation rendering of the internal heat source object.

[0091] Specifically, in the embodiment, it is to be noted that when the embodiment detects an internal heat source object such as an airplane, a car, and a train in the target scene, the embodiment immediately adds a fifth preset script to the current internal heat source object, and at the same time, further simulates the internal heat source strength, the heat source radius, and the heat source attenuation coefficient inside the current internal heat source object through the fifth preset script. Preferably, the fifth preset script provided by the embodiment is set as a heatInSourceCal (internal heat source simulation) script.

[0092] Further, the embodiment further calculates the surface temperature of the current internal heat source object through a sixth preset script, and further calculates the second surface radiation intensity corresponding to the current internal heat source object according to the material type of the current internal heat source object, the object self-radiation intensity, the solar radiation intensity, and the surface temperature, so as to simply and conveniently complete the radiation rendering of the current internal heat source object. Preferably, the sixth preset script provided by the embodiment is set as a TemperatureCtrl (internal heat source radiation calculation) script.

[0093] It is to be noted that the method provided by the fifth embodiment of the application has the same implementation principle and some technical effects as the first embodiment.
