Specifically, when different positions need to be observed, or different holding postures need to be adopted, the lens 2 can be rotated to adjust the observation position of the lens 2, so that the problem that a plurality of different types of infrared equipment need to be configured in the prior art is solved. As shown in fig. 1 and 2, the surfaces of the lens 2 and the handle 1, which are abutted against each other, are respectively defined as a rotating surface 20 and a reference surface 10, and the rotating surface 20 rotates along the reference surface 10 within a range that does not leave the reference surface 10, so that the purpose of adjusting different observation positions of the lens 2 by utilizing eccentricity can be achieved. In addition, the infrared imaging module is an existing component, which is a component that is commonly used in thermal infrared imagers, and the working principle of the infrared imaging module will be briefly described later.

As an optimization scheme of the embodiment of the present invention, please refer to fig. 1 to 9, in which the rotation surface 20 and the reference surface 10 are both circular or polygonal. In this embodiment, the shape of the portion where the lens 2 and the handle 1 are butted against each other may be various, because if the portion is disposed obliquely, the object of changing the posture of the lens from the posture of fig. 1 to the posture of fig. 2 can be achieved by utilizing the eccentricity in rotation. So whether round or square or even triangular, pentagonal or irregular in shape, is in principle possible, but in order to ensure product consistency, it is preferably round, for example oval, so that no excessive clearance between the lens 2 and the handle 1 is ensured, whether in the position of fig. 1 or fig. 2.

As an optimization scheme of the embodiment of the present invention, please refer to fig. 1 to 9, the lens 2 is rotatably installed on one of the end portions of the handle 1, and the lens 2 and the handle 1 are arranged in a straight line.

As an optimization scheme of the embodiment of the present invention, please refer to fig. 1 to 9, the thermal infrared imager further includes an interface 5 mountable on an external device. In this embodiment the interface 5 is used for external equipment mounting, such as a gun base, which can then be viewed through the second display 4. It is also possible that the interface 5 is arranged on the handle 1 and is also arranged on the housing of the lens 2. Preferably, the interface 5 is a threaded interface, which can be mounted by means of screws.

As an optimization scheme of the embodiment of the utility model, please refer to fig. 1 to fig. 9, the thermal infrared imager further comprises an operation button 6 for controlling the work of the infrared imaging module.

After the operation key 6 is pressed, an internal circuit supplies power to the infrared imaging module to start the infrared imaging module, which is also conventional in the art and will not be described in detail herein. The operation button 6 may be provided on the handle 1 or on the housing of the lens 2, as in the case of the interface 5 described above. Preferably, the operation installation is close to the setting of first display screen 3, makes things convenient for people's finger operation.

As an optimized solution of the embodiment of the present invention, please refer to fig. 1 to 9, the lens 2 rotates on the handle 1 through the rotating mechanism. In this embodiment, the rotation may be manual, or may be automatic. The automatic operation can be realized by adopting a rotating mechanism. The rotation of the lens 2 can be controlled in linkage with the operation button 6, that is, by controlling the operation of the rotation mechanism by the operation button 6. The rotation mechanism may be driven to rotate by existing rotation equipment, such as a micro-motor.

In the present embodiment, the lens 2 can adopt stepless rotation, which is a prior art, and the working principle thereof will not be described in detail here. The rotational arrow in fig. 1 is a 360 ° rotation schematic.

Next, the present embodiment will explain the principle of infrared imaging, and although infrared imaging is a conventional technology, the present application will briefly explain:

the lens 2 is used for collecting scene images, and a digital signal processing board in the thermal imager is responsible for image preprocessing and image analysis. The analyzed and processed data stream is a video stream overlapped with identification and character information, and then the video stream can be displayed on a display screen after being unpacked. Of course, besides, the data can also be packaged into a protocol format by the WiFi module for transmission. And the computer terminal receives the data, unpacks the data through application software and displays the unpacked data on a screen. The detailed information may also be learned by the auxiliary device manager for convenience in receiving the display with a cell phone. The scene analog signals read out from the detector reading circuit are transmitted to a digital signal processing chip after AD conversion, and the digital signal processing chip carries out image preprocessing and image analysis. In the image preprocessing stage, interframe noise is removed through time domain filtering, and nonuniform correction is carried out to eliminate the influence of nonuniform response of a focal plane array unit. The 16-bit data is compressed in dynamic range to form 8-bit gray scale map. The dynamic range compression is not only beneficial to better analysis of an analysis algorithm, but also convenient for terminal display. The 8-bit image after the dynamic range compression is analyzed and processed, the target and the background are distinguished by adjusting the contrast and the brightness in the compression process, and a global threshold value needs to be calculated for binary segmentation. And (3) adaptively calculating the segmentation threshold of the whole image by using an Otsu threshold algorithm, and segmenting the gray image into a binary image through the threshold. At this time, the computer which is not closed becomes a foreground image, and the closed computer is fused into a background. And according to the position information calibrated during installation and the acquired position map (binary map), subtracting the two images and then identifying the computer with abnormal startup or shutdown by combining the position information. And (5) superposing the position information, counting the number of the starting computers, and finishing the whole analysis algorithm to finish the infrared imaging.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
