[0024] The method embodiments provided in the embodiments of the present application can be executed in a computer terminal or similar computing device or cloud platform or independent physical server or software platform, wherein the above software platform is run through one or more servers. Taking running on a computer terminal as an example, Figure 1 is a hardware structure block diagram of a temperature detection method according to an embodiment of the present application.

[0025] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as computer programs corresponding to the methods in the embodiments of the present application. The processor 102 executes various functional applications and data processing by running the computer programs stored in the memory 104, that is, the above-mentioned methods are implemented. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory.

[0027] In this embodiment, a temperature detection method is provided, which is applied to the above-mentioned computer terminal.

[0028] Figure 2 : is a flow chart of a temperature detection method according to an embodiment of the present application, the flow chart includes the following steps:

[0029] Step S202, acquiring a first temperature image and a second temperature image obtained by temperature acquisition of the target to be detected; wherein the first temperature image is an image measured by the acquisition device in a set first temperature measurement range, and the second temperature image is an image measured by the acquisition device in a set second temperature measurement range.

[0030] It is understandable that the acquisition device specifically refers to an infrared detector. The first temperature range specifically refers to a relatively low temperature measurement range, such as 0 to 350 degrees, and the second temperature range specifically refers to a relatively high temperature measurement range, such as 300 to 1000 degrees. The specific settings of the first temperature range and the second temperature range can be combined with the performance settings of the infrared detector.

[0031] In some exemplary embodiments, the acquisition device includes a first acquisition device and a second acquisition device; the acquisition of the first temperature image and the second temperature image obtained by temperature acquisition of the target to be detected includes: acquiring the first temperature image acquired by the first acquisition device within a set first temperature measurement range and at a first field of view angle; acquiring the second temperature image acquired by the second acquisition device within a set second temperature measurement range and at a second field of view angle, wherein the first field of view angle is smaller than the second field of view angle.

[0032] It should be noted that the first acquisition device and the second acquisition device can be two infrared detectors of the same model, so that their physical output performance is theoretically close and the image synchronization is better. The first field of view angle is the field of view angle corresponding to the first temperature measurement range, that is, the field of view angle responsible for low normal temperature, and the first field of view angle can be set to a 25-degree field of view angle; the second field of view angle is the field of view angle corresponding to the second temperature measurement range, that is, the field of view angle responsible for high temperature, and the second field of view angle can be set to a 32-degree field of view angle. A lens with a large field of view angle will theoretically obtain less infrared radiation.

[0033] Step S204, registering the first temperature image and the second temperature image to obtain the registered first temperature image and the second temperature image;

[0034] The registering of the first temperature image and the second temperature image refers to a process of processing the two images into images of the same size.

[0035] In an exemplary embodiment, the registering the first temperature image and the second temperature image to obtain the registered first temperature image and the second temperature image includes: cropping and scaling the first temperature image and the second temperature image according to the distance between the acquisition device and the target to be detected to obtain the first temperature image and the second temperature image of the same size; and obtaining the registered first temperature image and the second temperature image based on the first temperature image and the second temperature image of the same size.

[0036] The distance between the acquisition device and the target to be detected refers to the distance between the first acquisition device and the target to be detected, and the distance between the second acquisition device and the target to be detected. Since the first acquisition device and the second acquisition device are arranged in a horizontal parallel structure and are as close as possible, it can be considered that the distances between the two devices and the target to be detected are the same.

[0037] It is understandable that the distance between the acquisition device and the target to be detected is different, and for lenses with different field of view angles, the sizes of the measured images will be different. By cropping and scaling the first temperature image and the second temperature image, the first temperature image and the second temperature image of the same size are obtained.

[0038] In an exemplary embodiment, the first temperature image and the second temperature image are cropped and scaled according to the distance between the acquisition device and the target to be detected to obtain the first temperature image and the second temperature image of the same size, including: cropping the first temperature image and the second temperature image according to the distance between the acquisition device and the target to be detected to obtain the cropped first temperature image and the second temperature image; scaling the cropped first temperature image and the second temperature image to the target size to obtain the first temperature image and the second temperature image of the same size.

[0039] It should be noted that the target size is the size that the first temperature image and the second temperature image need to reach.

[0040] Step S206, marking the registered first temperature image with a first marker to obtain a marked first temperature image, and marking the registered second temperature image with a second marker to obtain a marked second temperature image;

[0041] In an exemplary embodiment, the method of using a first marker to mark the registered first temperature image to obtain the marked first temperature image includes: detecting the registered first temperature image to determine the temperature corresponding to each pixel in the first temperature image; using the first marker to mark the pixel points in the first temperature image whose temperature is within a preset range of the first temperature to obtain the marked first temperature image.

[0042] The first temperature preset range may be a temperature range set to identify the first temperature image, and the first temperature preset range may be set to be less than 350 degrees. Specifically, after the first temperature image and the second temperature image are registered, the registered first temperature image and the second temperature image may be detected respectively; for the registered first temperature image, which specifically refers to a low-normal temperature infrared image, the first identifier may be used to mark pixels below 350 degrees, and the first identifier may be a color, a number, etc.

[0043] In an exemplary embodiment, the second temperature image after registration is marked with a second marker to obtain the marked second temperature image, including: detecting the second temperature image after registration to determine the temperature corresponding to each pixel in the second temperature image; and marking the pixel points in the second temperature image whose temperature is within a second temperature preset range using the second marker to obtain the marked second temperature image.

[0044] The second temperature preset range may be a temperature range set to identify the second temperature image, and the second temperature preset range may be set to be greater than 300 degrees. Specifically, after the first temperature image and the second temperature image are registered, the registered first temperature image and the second temperature image may be detected respectively; for the registered second temperature image, which specifically refers to the high-temperature infrared image, a second identifier may be used to mark pixels above 300 degrees, and the second identifier may be a color, a number, etc.; wherein the first identifier and the second identifier are different.

[0045] Step S208: determining a temperature detection result based on the marked first temperature image and the marked second temperature image.

[0046] In some exemplary embodiments, determining the temperature detection result based on the marked first temperature image and the marked second temperature image includes: respectively making unmarked pixels in the marked first temperature image and the marked second temperature image transparent to obtain the first temperature image and the second temperature image after transparency; determining the temperature detection result based on the first temperature image and the second temperature image after transparency.

[0047] Among them, the unmarked pixels in the marked first temperature image and the marked second temperature image can be processed with 100% transparency. At this time, the transparent first temperature image and the second temperature image retain the data and details of the low temperature and the high temperature. Finally, the image displayed to the user through the display screen maintains the image clarity of the low temperature and retains the information of the high temperature target.

[0048] Through the above steps S202-S208, a first temperature image and a second temperature image are obtained by temperature acquisition of the target to be detected. The first temperature image is an image measured by the acquisition device in a set first temperature measurement range, and the second temperature image is an image measured by the acquisition device in a set second temperature measurement range, that is, the first temperature image and the second temperature image correspond to different temperature measurement ranges, and the temperature included in the first temperature measurement range is less than the temperature included in the second temperature measurement range. By aligning the first temperature image and the second temperature image, the aligned first temperature image and the second temperature image are obtained, and then the first temperature image and the second temperature image are respectively marked, so that the temperature detection result can be obtained based on the temperature images in different temperature ranges, thereby improving the accuracy of temperature detection.

[0049] In order to better understand the process of the above-mentioned temperature detection method, the above-mentioned temperature detection method is described below in combination with an optional embodiment, but it is not used to limit the technical solution of the embodiment of the present application.

[0050] In order to process the image clearly visible in a wide temperature range, an infrared imaging device that can measure in a wide temperature range is designed. Although the original infrared device can measure a wide temperature range, it is done by switching different temperature measurement gears. Because the range of grayscale response is fixed, if the accuracy of normal temperature is to be guaranteed, the high temperature area will not be visible. If the high temperature area is to be guaranteed, the low normal area will be suppressed. It is impossible to achieve the temperature measurement accuracy in a wide temperature range and maintain image details at the same time. The limitation of the original infrared solution is that the grayscale response space of each detector is fixed. It can be adjusted to adapt to different temperature ranges such as 0~150; 0~350; 300~1000 by configuring parameters, but it cannot respond to all temperature segments at the same time. At this time, by adding one more infrared detector, one detector is responsible for the normal temperature segment response, and the other is responsible for the high temperature segment response. A dual-light mode architecture similar to infrared visible light is adopted, and then the output image is fused. In this way, the details of the low normal temperature part can be well preserved, and the medium and high temperature temperature measurement and image details can be guaranteed.

[0051] The first step is to select two infrared detectors of the same model, so that their physical output performance is theoretically close and the image synchronization is better.

[0052] Choose two infrared lenses. The one responsible for low and normal temperatures is assumed to have a 25-degree field of view. The other lens responsible for high temperatures has a slightly larger field of view, assuming 32 degrees (25 and 32 degrees are commonly used angles on the market). The lens with a larger field of view will theoretically obtain less infrared radiation, but because it is the part mainly responsible for sensing high temperatures, it can make up for this.

[0053] The two detectors are placed horizontally and in parallel, as close as possible, but with thermal insulation in the middle so that internal heat does not affect image quality.

[0054] The parameters of the detectors responsible for low normal temperature are configured so that the temperature measurement range is 0 to 350 degrees, and the parameters of the detectors responsible for high temperature section are configured so that the temperature measurement range is 300 to 1000 degrees.

[0055] The two infrared images are transmitted to the back-end processor via the network or digital interface for fusion and registration processing. The high-temperature image with a 32-degree field of view is cropped and scaled at different distances to match the low-temperature 25-degree infrared field of view image. After the matching is completed, the two images are actually superimposed. At this time, the temperature of the two images is detected separately. The low-temperature infrared image marks the pixels below 350 degrees; the high-temperature infrared image marks the pixels above 300 degrees, and then the unmarked pixels of the two images are 100% transparent. At this time, the image display retains both low-temperature and high-temperature data and details.

[0056] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of each embodiment of the present application.
