技术领域technical field

本申请涉及光电检测技术领域，特别是涉及一种火情检测方法、装置、***及电子设备。The present application relates to the technical field of photoelectric detection, and in particular, to a fire detection method, device, system and electronic equipment.

背景技术Background technique

为了能够及时采取应对措施以避免火情蔓延，需要及时发现火情。相关技术中，可以根据发生火情的目标温度较高的特点，利用热成像相机拍摄监控场景的热成像图像，通过对热成像图像进行分析以确定监控场景中是否存在温度过高的目标，如果监控场景中存在温度过高的目标，则确定该目标发生火情。In order to be able to take timely countermeasures to prevent the fire from spreading, it is necessary to detect the fire in time. In the related art, a thermal imaging camera can be used to take a thermal imaging image of the monitoring scene according to the high temperature of the target where the fire occurs, and the thermal imaging image can be analyzed to determine whether there is a target with an excessively high temperature in the monitoring scene. If there is a target with too high temperature in the monitoring scene, it is determined that the target is on fire.

但是在一些复杂的监控场景中，可能因火情以外的其他因素导致目标在热成像图像中呈现出的温度过高，因此在这些监控场景中火情的误报率较高。However, in some complex monitoring scenarios, the temperature of the target in the thermal imaging image may be too high due to factors other than fire, so the false alarm rate of fire in these monitoring scenarios is high.

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.

在部分地区，一些人员可能会通过焚烧秸秆的方式对秸秆进行销毁。焚烧秸秆将产生大量的有毒物质，污染空气和土壤，并且可能引发更大的火灾，因此需要对焚烧秸秆的行为进行管理。为便于对焚烧秸秆的行为进行管理，相关技术中可以通过以下方式检测是否存在因焚烧秸秆引起的火情：In some areas, some personnel may destroy straw by burning straw. Burning straw will produce a lot of toxic substances, pollute the air and soil, and may cause larger fires, so straw burning needs to be managed. In order to facilitate the management of straw burning behavior, the following methods can be used to detect whether there is a fire caused by burning straw:

利用设置有热成像相机的巡航设备，如飞行器，在监控场景中巡航拍摄，采集监控场景的热成像图像。对热成像图像中目标的灰度进行分析，由于温度越高的目标在热成像图像中目标的灰度往往越高，因此如果热成像图像中存在灰度过高的目标，则可以认为该目标发生有火情。Use cruise equipment equipped with thermal imaging cameras, such as aircraft, to cruise and shoot in the monitoring scene, and collect thermal imaging images of the monitoring scene. Analyze the grayscale of the target in the thermal imaging image. Since the target with higher temperature tends to have a higher grayscale of the target in the thermal imaging image, if there is a target with too high grayscale in the thermal imaging image, it can be considered that the target There is a fire.

但是，焚烧秸秆往往发生在农村地区，而农村地区可能存在房屋、农机车辆(播种机、拖拉机等)、工厂等目标，因此可能因房屋屋顶反光、农机车辆发动机发射热量、工厂中的热机发射热量，等原因导致监控场景的热成像图像在没有发生火情时也可能存在灰度值过高的目标，因此可能错误地判断这些目标发生有火情。可见，该方法在农村这种监控场景中误报率可能较高。However, straw burning often occurs in rural areas, and there may be targets such as houses, agricultural machinery vehicles (planters, tractors, etc.), factories, etc. in rural areas. Therefore, it may be caused by the reflection of the roof of houses, the heat emitted by the engines of agricultural machinery vehicles, and the heat emitted by the heat engine in the factory. , and other reasons, the thermal imaging image of the monitoring scene may also have targets with too high gray value when there is no fire, so it may be wrongly judged that there is fire in these targets. It can be seen that the false alarm rate of this method may be higher in rural monitoring scenarios.

基于此，本申请实施例提供了一种火情检测方法，该火情检测方法可以应用于任一具有火情检测功能的电子设备上，方法可以参见图1，包括：Based on this, an embodiment of the present application provides a fire detection method, which can be applied to any electronic device with a fire detection function. The method can be referred to in FIG. 1 , including:

S101，获取高温目标的可见光图像。S101, acquiring a visible light image of a high temperature target.

S102，在根据可见光图像确定出高温目标符合火情现象条件和/或不符合红外光源条件的情况下，确定高温目标发生火情。S102, when it is determined according to the visible light image that the high-temperature target meets the fire phenomenon condition and/or does not meet the infrared light source condition, determine that the high-temperature target is on fire.

选用该实施例，可以在温度判断的基础上，根据可见光图像中呈现的信息进一步判断造成高温的原因是否为火情，从而有效降低在复杂应用场景中的误报率。By choosing this embodiment, on the basis of temperature judgment, it can be further judged whether the cause of the high temperature is fire according to the information presented in the visible light image, thereby effectively reducing the false alarm rate in complex application scenarios.

在S101中，高温目标为根据从监控场景中采集到的红外光信号从监控场景中确定出的温度高于预设温度阈值的目标。本文中的目标可以是指目标对象，如草垛、树木等，也可以是指目标位置。In S101, the high temperature target is a target whose temperature determined from the monitoring scene according to the infrared light signal collected from the monitoring scene is higher than a preset temperature threshold. The target in this paper can refer to the target object, such as haystacks, trees, etc., or it can refer to the target location.

可以理解的是，任何温度超过绝对零度的物体理论上将辐射红外光，而物体的温度越高则辐射的红外光的能量越高，因此理论上根据从监控场景中采集到的红外光信号可以确定出监控场景中温度高于预设温度阈值的目标。目标的温度可以是通过分析热成像图像得到的，也可以是通过其他非接触式的温度测量方法测量得到的，本实施例对此不做限制。预设温度阈值可以是根据应用场景进行设置，例如以前述检测焚烧秸秆的应用场景为例，预设温度阈值可以是秸秆的燃点。It can be understood that any object whose temperature exceeds absolute zero will theoretically radiate infrared light, and the higher the temperature of the object, the higher the energy of the radiated infrared light. Therefore, theoretically, according to the infrared light signal collected from the monitoring scene, it can be Determine the target whose temperature is higher than the preset temperature threshold in the monitoring scene. The temperature of the target may be obtained by analyzing the thermal imaging image, or may be obtained by measuring other non-contact temperature measurement methods, which is not limited in this embodiment. The preset temperature threshold may be set according to the application scenario. For example, taking the aforementioned application scenario of detecting burning straw as an example, the preset temperature threshold may be the ignition point of the straw.

可以理解的是，由于一些参数与温度关联，如目标的温度与目标在热成像图像的灰度关联，因此确定目标的温度是否高于预设温度阈值的方式可以是直接比较目标的温度与预设温度阈值，也可以是通过与温度关联的其他参数确定目标的温度是否高于预设温度阈值，例如可以是比较目标在热成像图像的灰度与预设灰度阈值，以确定目标的温度是否高于预设温度阈值。It can be understood that, since some parameters are related to temperature, such as the temperature of the target is related to the grayscale of the target in the thermal imaging image, the way to determine whether the temperature of the target is higher than the preset temperature threshold may be to directly compare the temperature of the target with the preset temperature. Setting the temperature threshold, it is also possible to determine whether the temperature of the target is higher than the preset temperature threshold through other parameters related to the temperature. For example, it can be compared between the grayscale of the target in the thermal imaging image and the preset grayscale threshold to determine the temperature of the target. Is it above the preset temperature threshold.

在S102中，火情现象条件为高温目标发生预设火情现象，红外光源条件为高温目标为预设红外光源。预设火情现象可以是指因火情发生所引起的现象，例如产生烟雾、产生火焰、高温目标周遭的空气的折射率发射改变等。In S102, the fire phenomenon condition is that a preset fire phenomenon occurs in the high temperature target, and the infrared light source condition is that the high temperature target is a preset infrared light source. The preset fire phenomenon may refer to a phenomenon caused by the occurrence of fire, such as the generation of smoke, the generation of flame, the change of the refractive index emission of the air around the high-temperature target, and the like.

预设红外光源可以是根据应用场景预先设置的红外光源，以前述检测焚烧秸秆的应用场景为例，预设红外光源可以包括农机车辆、房屋屋顶等，在其他可能的应用场景中预设红外光源也可以包括除农机车辆、房屋屋顶以外的其他红外光源。本文中的红外光源是指具备向外发射红外光能力的物体，所发射的红外光可以是该物体辐射的红外光，也可以是物体反射的红外光，并且应当理解的是，由于所有高于绝对零度的物体均可以辐射红外光，因此下文中通过反射红外光发射红外光的红外光源并不特指该红外光源只能够通过反射红外光的方式发射红外光，该红外光源同样可以辐射红外光。并且在本申请实施例中，预设红外光源应当不包括因火情产生的红外光源，如焚烧秸秆产生的红外光源。The preset infrared light source may be an infrared light source preset according to the application scenario. Taking the aforementioned application scenario of detecting burning straw as an example, the preset infrared light source may include agricultural machinery vehicles, roofs of houses, etc., and the infrared light source is preset in other possible application scenarios. Other infrared light sources other than agricultural vehicles and house roofs can also be included. The infrared light source in this article refers to an object capable of emitting infrared light outward. The emitted infrared light can be either the infrared light radiated by the object or the infrared light reflected by the object. Objects at absolute zero can radiate infrared light, so the following infrared light source that emits infrared light by reflecting infrared light does not specifically mean that the infrared light source can only emit infrared light by reflecting infrared light. The infrared light source can also radiate infrared light. . And in the embodiment of the present application, the preset infrared light source should not include the infrared light source generated by fire, such as the infrared light source generated by burning straw.

可以理解的是，预设火情现象是因火情发生引起的现象，因此相比于不符合火情现象条件的高温目标，符合火情现象条件的高温目标发生火情的概率更高。It can be understood that the preset fire phenomenon is a phenomenon caused by the occurrence of fire, so compared with the high temperature target that does not meet the fire phenomenon conditions, the high temperature target that meets the fire phenomenon conditions has a higher probability of fire occurrence.

并且，由于预设红外光源可以在未发生火情时发射红外光，因此如果高温目标为预设红外光源，则根据从监控场景中采集到的红外光信号确定出高温目标温度高于温度阈值的原因可能并非高温目标发生火情，因此相比于不符合红外光源条件的高温目标，符合火情现象条件的高温目标发生火情的概率更低。Moreover, since the preset infrared light source can emit infrared light when no fire occurs, if the high temperature target is the preset infrared light source, it is determined according to the infrared light signal collected from the monitoring scene that the high temperature target temperature is higher than the temperature threshold. The reason may not be that the high-temperature target has a fire, so compared with the high-temperature target that does not meet the conditions of the infrared light source, the high-temperature target that meets the conditions of the fire phenomenon has a lower probability of fire.

因此，可以在高温目标符合火情现象条件和/或不符合红外光源条件的情况下，确定高温目标发生火情。根据应用场景的不同，高温目标符合火情现象条件和/或不符合红外光源条件的情况可以是指以下四种情况中的不同情况：Therefore, it can be determined that the high-temperature target is on fire when the high-temperature target meets the fire phenomenon conditions and/or does not meet the infrared light source conditions. According to different application scenarios, the condition that the high temperature target meets the fire phenomenon conditions and/or does not meet the infrared light source conditions may refer to different situations among the following four situations:

对于高温目标符合火情现象条件和/或不符合红外光源条件的情况是指上述情况一的情况(下文称情况五)下，可以仅判断高温目标是否符合火情现象条件，而无需判断高温目标是否符合红外光源条件。对于高温目标符合火情现象条件和/或不符合红外光源条件的情况是指上述情况二的情况(下文称情况六)下，可以仅判断高温目标是否符合红外条件，而无需判断高温目标是否符合红外光源条件。对于高温目标符合火情现象条件和/或不符合红外光源条件的情况是指上述情况三或情况四的情况(下文称情况七)下，需要判断高温目标是否符合红外条件，且需要判断高温目标是否符合红外光源条件。。下面将结合前述焚烧秸秆检测的应用场景，对情况五、情况六、情况七这三种情况分别进行说明：For the case that the high temperature target meets the fire phenomenon conditions and/or does not meet the infrared light source conditions, it refers to the above-mentioned situation 1 (hereinafter referred to as the fifth situation), it is possible to only judge whether the high temperature target meets the fire phenomenon conditions, without judging the high temperature target. Whether the infrared light source conditions are met. For the case that the high-temperature target meets the fire phenomenon conditions and/or does not meet the infrared light source conditions, it refers to the above-mentioned situation 2 (hereinafter referred to as the sixth case), it is possible to only judge whether the high-temperature target meets the infrared conditions, without judging whether the high-temperature target meets the infrared conditions. Infrared light source conditions. For the case that the high temperature target meets the fire phenomenon conditions and/or does not meet the conditions of the infrared light source, it refers to the above-mentioned situation 3 or situation 4 (hereinafter referred to as the situation 7), it is necessary to judge whether the high temperature target meets the infrared conditions, and it is necessary to judge whether the high temperature target meets the infrared conditions. Whether the infrared light source conditions are met. . In the following, the three cases of Case 5, Case 6, and Case 7 will be described respectively in combination with the aforementioned application scenarios of straw burning detection:

情况五：Case five:

为描述方便，假设火情现象条件包括高温目标的预设范围内存在烟雾。For the convenience of description, it is assumed that the fire phenomenon conditions include the presence of smoke within the preset range of the high temperature target.

则可以是将可见光图像输入至预先经过训练的烟雾检测模型，得到烟雾检测模型输出的结果，该结果用于表示高温目标的预设范围内是否存在烟雾，如果该结果表示高温目标的预设范围内存在烟雾，则可以认为高温目标符合火情现象条件。该模型可以是基于深度学习得到的，也可以是基于传统机器学习得到的，本实施例对此不做限制。Then, the visible light image can be input into the pre-trained smoke detection model, and the result output by the smoke detection model can be obtained. The result is used to indicate whether there is smoke within the preset range of the high temperature target. If there is smoke, it can be considered that the high temperature target meets the fire phenomenon conditions. The model may be obtained based on deep learning, or may be obtained based on traditional machine learning, which is not limited in this embodiment.

可以理解的是，由于秸秆中往往包含较多水分，因此秸秆在焚烧过程中将产生较为明显的烟雾，而火情以外的其他原因导致的高温目标往往不会产生烟雾，例如农机车辆中的内燃机，在工作过程中温度较高但是并不会产生较为明显的烟雾，因此可以认为如果高温目标的预设范围内存在烟雾，则高温目标为焚烧秸秆导致的，如果高温目标的预设范围内不存在烟雾，则高温目标并非焚烧秸秆导致的。因此在该实施例中，如果根据可见光图像判断出高温目标的预设范围内存在烟雾，则可以确定高温目标发生火情，如果根据可见光图像判断出高温目标的预设范围内不存在烟雾，则可以确定高温目标未发生火情。It is understandable that because the straw often contains more water, the straw will produce obvious smoke during the incineration process, and the high temperature target caused by other reasons other than fire often does not produce smoke, such as the internal combustion engine in agricultural vehicles. , during the working process, the temperature is high but no obvious smoke is generated. Therefore, it can be considered that if there is smoke within the preset range of the high temperature target, the high temperature target is caused by burning straw. In the presence of smoke, the high temperature target is not the result of burning straw. Therefore, in this embodiment, if it is determined according to the visible light image that there is smoke within the preset range of the high-temperature target, it can be determined that the high-temperature target is on fire. It can be determined that the high temperature target is not on fire.

对于火情现象条件包括其他条件，如高温目标预设产生有火焰的情况原理是相同的，可以类推得到，在此不再赘述。The fire phenomenon conditions include other conditions, such as the case where a high temperature target is preset to generate a flame, the principle is the same, and it can be obtained by analogy, which will not be repeated here.

情况六：Case six:

红外光源条件可以包括高温目标为通过反射红外光的方式发射红外光的红外光源，也可以包括高温目标为预设类型的机器。其中，预设类型的机器可以包括前述农机车辆。The conditions of the infrared light source may include that the high-temperature target is an infrared light source that emits infrared light by reflecting infrared light, and may also include that the high-temperature target is a machine of a preset type. Wherein, the preset types of machines may include the aforementioned agricultural machinery vehicles.

如果红外光源条件包括高温目标为通过反射红外光的方式发射红外光的红外光源，由于焚烧秸秆时将产生烟雾，而烟雾对光线具有一定的阻挡效应，因此如果高温目标是由焚烧秸秆导致的，则高温目标发出的光线受到烟雾的阻挡，只有较少的光线能够被拍摄可见光图像的图像采集设备采集到，因此可见光图像中高温目标的曝光程度理论上较低。而如果高温目标为通过反射红外光的方式发射红外光的红外光源，如房屋屋顶，则该红外光源理论上应当同时对可见光产生一定的反射效应，并且由于未受到烟雾的阻挡，因此高温目标发出的光线中较多的光线能够被拍摄可见光图像的图像采集设备采集到，因此可见光图像中高温目标的曝光程度理论上较高。所以在一种可能的实施例中，可以根据可见光图像中高温目标的曝光程度，判断高温目标是否为通过反射红外光的方式发射红外光的红外光源。If the infrared light source conditions include that the high temperature target is an infrared light source that emits infrared light by reflecting infrared light, smoke will be generated when burning straw, and the smoke has a certain blocking effect on the light, so if the high temperature target is caused by burning straw, Then, the light emitted by the high-temperature target is blocked by the smoke, and only a small amount of light can be collected by the image acquisition device that captures the visible light image, so the exposure degree of the high-temperature target in the visible light image is theoretically low. If the high-temperature target is an infrared light source that emits infrared light by reflecting infrared light, such as the roof of a house, the infrared light source should theoretically have a certain reflection effect on visible light at the same time, and since it is not blocked by smoke, the high-temperature target emits More of the light in the visible light image can be collected by the image acquisition device that captures the visible light image, so the exposure degree of the high temperature target in the visible light image is theoretically higher. Therefore, in a possible embodiment, it can be determined whether the high-temperature target is an infrared light source that emits infrared light by reflecting infrared light according to the exposure degree of the high-temperature target in the visible light image.

示例性的，则可以是将可见光图像输入至预先经过训练的反光检测模型，得到反光检测模型输出的结果，该结果用于表示高温目标是否为通过反射红外光的方式发射红外光的红外光源。该反光检测模型为用于根据可见光图像中高温目标的曝光程度确定高温目标是否为通过反射红外光的方式发射红外光的红外光源的模型。该模型可以是基于深度学习得到的，也可以是基于传统机器学习得到的，本实施例对此不做限制。Exemplarily, the visible light image may be input into a pre-trained reflection detection model to obtain a result output by the reflection detection model, which is used to indicate whether the high-temperature target is an infrared light source that emits infrared light by reflecting infrared light. The reflection detection model is a model for determining whether the high temperature target is an infrared light source that emits infrared light by reflecting infrared light according to the exposure degree of the high temperature target in the visible light image. The model may be obtained based on deep learning, or may be obtained based on traditional machine learning, which is not limited in this embodiment.

可以理解的是，红外光源为发射红外光的物体，因此即使红外光源没有发生火情，红外光源发出的红外光的能量也相对较高，导致被确定为高温目标，例如房屋屋顶因阳光照射可能导致房屋屋顶成为高温目标，因此在该实施例中，可以认为如果根据可见光图像判断出高温目标为通过反射红外光的方式发射红外光的红外光源，则确定高温目标未发生火情。It can be understood that the infrared light source is an object that emits infrared light, so even if the infrared light source is not on fire, the energy of the infrared light emitted by the infrared light source is relatively high, resulting in the determination of a high temperature target. As a result, the roof of the house becomes a high temperature target. Therefore, in this embodiment, if it is determined from the visible light image that the high temperature target is an infrared light source that emits infrared light by reflecting infrared light, it is determined that the high temperature target is not on fire.

如果红外光源条件包括高温目标为高温目标为预设类型的机器，则可以是通过对可见光图像进行图像识别，以确定高温目标是否为预设类型的机器，示例性的，可以是将可见光图像输入至预先经过训练的农机车辆检测模型，得到农机车辆检测模型输出的结果，该结果用于表示高温目标是否为农机车辆。该农机车辆检测模型为用于识别农机车辆的模型。该模型可以是基于深度学习得到的，也可以是基于传统机器学习得到的，本实施例对此不做限制。If the conditions of the infrared light source include that the high-temperature target is a machine with a high-temperature target of a preset type, it can be determined whether the high-temperature target is a machine of a preset type by performing image recognition on the visible light image. Exemplarily, the visible light image can be input. To the pre-trained agricultural vehicle detection model, the result output by the agricultural vehicle detection model is obtained, and the result is used to indicate whether the high temperature target is an agricultural vehicle. The agricultural machinery vehicle detection model is a model for identifying agricultural machinery vehicles. The model may be obtained based on deep learning, or may be obtained based on traditional machine learning, which is not limited in this embodiment.

可以理解的是，红外光源为发射红外光的物体，因此即使红外光源没有发生火情，红外光源发出的红外光的能量也相对较高，导致被确定为高温目标，例如农机车辆因内燃机燃烧燃料可能导致农机车辆成为高温目标。因此，在该实施例中，可以认为如果根据可见光图像判断出高温目标为预设类型的机器，则可以确定高温目标未发生火情。It can be understood that the infrared light source is an object that emits infrared light. Therefore, even if the infrared light source does not have a fire, the energy of the infrared light emitted by the infrared light source is relatively high, resulting in the determination of a high temperature target. For example, agricultural machinery vehicles burn fuel due to internal combustion engines. May cause agricultural machinery vehicles to become high temperature targets. Therefore, in this embodiment, it can be considered that if it is determined according to the visible light image that the high-temperature target is a machine of a preset type, it can be determined that the high-temperature target is not on fire.

对于红外光源条件包括其他条件的情况，如高温目标为工厂烟囱，可以类推得到，在此不再赘述。For the case where the conditions of the infrared light source include other conditions, such as the high temperature target is a factory chimney, it can be obtained by analogy, and will not be repeated here.

情况七：预设条件存包括火情现象条件并且包括红外光源条件：Case 7: The preset conditions include fire phenomenon conditions and include infrared light source conditions:

在该情况下，可以是先判断高温目标是否符合火情现象条件，再判断高温目标是否符合红外光源条件，也可以是先判断高温目标是否符合红外光源条件，再判断高温目标是否符合火情现象条件，还可以是以并行或交替执行的方式判断高温目标是否符合红外光源条件，以及判断高温目标是否符合火情现象条件，本实施例对此不做限制。In this case, it is possible to first judge whether the high temperature target meets the conditions of the fire phenomenon, and then judge whether the high temperature target meets the conditions of the infrared light source, or it can first judge whether the high temperature target meets the conditions of the infrared light source, and then judge whether the high temperature target meets the fire phenomenon. It is also possible to judge whether the high temperature target meets the conditions of the infrared light source and whether the high temperature target meets the conditions of the fire phenomenon in a parallel or alternate manner, which is not limited in this embodiment.

并且，可以是对所有预设条件进行判断，也可以是对部分预设条件进行判断，例如，如果根据对部分预设条件进行判断后得到的判断结果，已经可以确定高温目标是否为发生火情，则可以不继续对剩余的预设条件进行判断。In addition, all preset conditions may be judged, or some preset conditions may be judged. For example, if the judgment result obtained after judging some preset conditions, it can already be determined whether the high temperature target is a fire situation. , it is not necessary to continue to judge the remaining preset conditions.

示例性的，假设在一种可能的实施例中，如果高温目标符合火情现象条件或不符合红外光源条件，则确定高温目标发生火情，如果高温目标不符合火情现象条件并且符合红外光源条件，则确定高温目标未发生火情。则在该实施例中，一种可能的判断流程可以参见图2，图2所示为本申请实施例提供的一种判断方式的一种流程示意图，可以包括：Exemplarily, it is assumed that in a possible embodiment, if the high temperature target meets the fire phenomenon condition or does not meet the infrared light source condition, it is determined that the high temperature target has a fire condition, and if the high temperature target does not meet the fire phenomenon condition and meets the infrared light source condition conditions, it is determined that the high temperature target does not have a fire. In this embodiment, a possible judgment process can refer to FIG. 2 . FIG. 2 shows a schematic flowchart of a judgment method provided in this embodiment of the present application, which may include:

判断方式可以参见前述相关说明，在此不再赘述。For the determination method, reference may be made to the foregoing related description, and details are not repeated here.

如果在S201中高温目标的预设范围内存在烟雾，此时已经可以确定高温目标发生火情，因此无需进行S202和S203的判断，可以生成用于表示高温目标符的预设范围内存在业务的判断结果，根据该判断结果可以确定高温目标发生火情。If there is smoke within the preset range of the high temperature target in S201, it can already be determined that the high temperature target is on fire at this time, so there is no need to perform the judgments in S202 and S203, and a message can be generated to indicate that there is a business within the preset range of the high temperature target symbol. The judgment result, according to the judgment result, it can be determined that the high temperature target is on fire.

同理，如果在S201中高温目标的预设范围内不存在烟雾，在S202中高温目标为通过反射红外光的方式发射红外光的红外光源，则已经可以确定高温目标未发生火情，因此无需进行S202和S203的判断，可以生成用于表示高温目标的预设范围内不存在也烟雾且高温目标为通过反射红外光的方式发射红外光的红外光源的判断结果，根据该判断结果可以确定高温目标未发生火情。Similarly, if there is no smoke within the preset range of the high-temperature target in S201, and the high-temperature target is an infrared light source that emits infrared light by reflecting infrared light in S202, it can already be determined that no fire has occurred in the high-temperature target, so there is no need to. Carrying out the judgments of S202 and S203, can generate a judgment result indicating that there is no smoke within the preset range of the high-temperature target and that the high-temperature target is an infrared light source that emits infrared light by reflecting infrared light, and according to the judgment result, a high temperature can be determined The target was not on fire.

如果在S201中高温目标的预设范围内不存在烟雾，在S202中高温目标不为通过反射红外光的方式发射红外光的红外光源，并且在S203中高温目标为预设类型的机器，则可以生成用于表示高温目标的预设范围内不存在也烟雾，并且高温目标不为通过反射红外光的方式发射红外光的红外光源，并且高温目标为预设类型的机器的判断结果。根据该判断结果可以确定高温目标未发生火情。If there is no smoke within the preset range of the high-temperature target in S201, the high-temperature target is not an infrared light source that emits infrared light by reflecting infrared light in S202, and the high-temperature target is a preset type of machine in S203, you can A judgment result is generated indicating that there is no smoke within the preset range of the high temperature target, the high temperature target is not an infrared light source that emits infrared light by reflecting infrared light, and the high temperature target is a preset type of machine. According to the judgment result, it can be determined that there is no fire at the high temperature target.

如果在S201中高温目标的预设范围内不存在烟雾，在S202中高温目标不为通过反射红外光的方式发射红外光的红外光源，并且在S203中高温目标不为预设类型的机器，则可以生成用于表示高温目标的预设范围内不存在也烟雾，并且高温目标不为通过反射红外光的方式发射红外光的红外光源，并且高温目标不为预设类型的机器的判断结果。根据该判断结果可以确定高温目标发生火情。If there is no smoke within the preset range of the high-temperature target in S201, the high-temperature target is not an infrared light source that emits infrared light by reflecting infrared light in S202, and the high-temperature target is not a preset type of machine in S203, then A judgment result can be generated indicating that there is no smoke within a preset range of the high temperature target, that the high temperature target is not an infrared light source that emits infrared light by reflecting infrared light, and that the high temperature target is not a preset type of machine.

示例性的，可以是确定热成像图像中各像素点的灰度值，如果存在至少一个像素点的灰度值大于预设灰度阈值，则将灰度值大于预设灰度阈值的像素点所属的目标作为高温目标。Exemplarily, the gray value of each pixel in the thermal imaging image can be determined, and if there is at least one pixel whose gray value is greater than the preset gray threshold, then the gray value of the pixel whose gray value is greater than the preset gray threshold is determined. The target belongs to as the high temperature target.

在另一种可能的实施例中，数据采集单元310还可以包括温湿度传感器以及测距组件。In another possible embodiment, the data acquisition unit 310 may further include a temperature and humidity sensor and a distance measuring component.

其中，温湿度传感器用于采集监控场景的温湿度信息，测距组件用于采集距离信息，其中，距离信息用于表示数据采集单元距离监控场景中目标的距离，可以理解的是，由于数据采集单元可能和其他部件之间存在一定的位置关系，因此距离信息虽然用于表示数据采集单元距离监控场景中目标的距离，但是距离信息也可以是除数据采集单元与监控场景中目标的距离以外的其他几何参数。Among them, the temperature and humidity sensor is used to collect the temperature and humidity information of the monitoring scene, and the ranging component is used to collect the distance information, wherein the distance information is used to indicate the distance between the data acquisition unit and the target in the monitoring scene. There may be a certain positional relationship between the unit and other components, so although the distance information is used to indicate the distance between the data acquisition unit and the target in the monitoring scene, the distance information can also be other than the distance between the data acquisition unit and the target in the monitoring scene. other geometric parameters.

测距组件根据应用场景的不同可以不同，示例性的，以数据采集单元设置于飞行器为例，测距组件可以是俯仰角传感器，用于测量热成像相机拍摄到热成像图像时相对飞行器的俯仰角，根据该俯仰角以及飞行器的高度可以计算得到数据采集单元距离监控场景中目标的距离。The ranging component can be different according to different application scenarios. For example, taking the data acquisition unit set on the aircraft as an example, the ranging component can be a pitch angle sensor, which is used to measure the pitch relative to the aircraft when the thermal imaging camera captures the thermal imaging image. According to the pitch angle and the height of the aircraft, the distance between the data acquisition unit and the target in the monitoring scene can be calculated.

联动单元320可以是根据热成像相机拍摄到的热成像图像以及温湿度信息、距离信息，从监控场景中确定出温度高于预设温度阈值的目标。The linkage unit 320 may determine a target whose temperature is higher than a preset temperature threshold from the monitoring scene according to the thermal imaging image captured by the thermal imaging camera, temperature and humidity information, and distance information.

示例性的，可以是根据温湿度信息、距离信息(如果数据采集单元设置于飞行器，则也可以是根据温湿度信息、距离信息以及飞行器的巡航灵敏度信息)，计算灰度阈值，并确定热成像图像中各像素点的灰度值，如果存在至少一个像素点的灰度值大于灰度阈值，则将灰度值大于预设灰度阈值的像素点所属的目标作为高温目标。Exemplarily, it can be based on temperature and humidity information and distance information (if the data acquisition unit is arranged on the aircraft, it can also be based on temperature and humidity information, distance information and cruise sensitivity information of the aircraft), calculate the grayscale threshold, and determine the thermal image. The gray value of each pixel in the image, if the gray value of at least one pixel is greater than the gray threshold, the target to which the pixel whose gray value is greater than the preset gray threshold belongs is regarded as a high temperature target.

联动单元320可以对数据采集单元310进行控制，示例性的，联动单元320可以在从监控场景中确定出高温目标之后，调整数据The linkage unit 320 can control the data acquisition unit 310. Exemplarily, the linkage unit 320 can adjust the data after determining the high temperature target from the monitoring scene

以数据采集单元310设置于飞行器为例，联动单元320可以控制飞行器的运动，示例性的，假设联动单元320根据数据采集单元310确定出高温目标，则联动单元320可以控制飞行器飞行至高温目标的正上方，并在飞行器稳定于高温目标的正上方后，控制数据采集单元310拍摄高温目标的可见光图像。Taking the data acquisition unit 310 disposed on the aircraft as an example, the linkage unit 320 can control the movement of the aircraft. Exemplarily, if the linkage unit 320 determines the high temperature target according to the data acquisition unit 310, the linkage unit 320 can control the aircraft to fly to the high temperature target. Right above, and after the aircraft is stabilized right above the high-temperature target, the data acquisition unit 310 is controlled to capture a visible light image of the high-temperature target.

可以理解的是，监控场景中可能存在一些区域，这些区域即使在未发生火情的情况下，也可能存在燃烧现象。如工厂可能燃烧煤炭、烟囱内可能燃烧柴火，这些非火情的燃烧现象可能被错误的检测为火情，导致误报率增加。因此，在一种可能的实施例中，联动单元320可以根据监控数据，从监控场景中除屏蔽区域以外的其他区域确定出温度高于预设温度阈值的目标，作为高温目标。其中屏蔽区域包括预设工厂区域、预设烟囱区域中的一种或多种区域。预设屏蔽区域可以是用户预先设置的，也可以是根据地图信息预先确定得到的。选用该实施例，可以进一步有效降低误报率。It is understandable that there may be some areas in the monitoring scene that may be burning even when there is no fire. For example, coal may be burned in factories and firewood may be burned in chimneys. These non-fire burning phenomena may be wrongly detected as fires, resulting in increased false alarm rates. Therefore, in a possible embodiment, the linkage unit 320 may, according to the monitoring data, determine a target whose temperature is higher than the preset temperature threshold from other areas in the monitoring scene except the shielded area, as a high temperature target. The shielding area includes one or more of a preset factory area and a preset chimney area. The preset shielding area may be preset by the user, or may be determined in advance according to map information. By selecting this embodiment, the false alarm rate can be further effectively reduced.

Exemplarily, it can be in the form of an alarm sound, or it can be in the form of sending alarm information, and the sent alarm information can be sent to the preset alarm center. , or it may be sent to a preset user terminal, which is not limited in this embodiment.
