Embodiment 1

[0027] A passive infrared panoramic camera is an infrared panoramic camera with a viewing angle of more than 180 degrees up to 190 degrees and a horizontal coverage of 360 degrees, such as figure 1 As shown, the camera includes an image processing module 1 and an imaging lens group 2, the image processing module receives and processes the output signal of the imaging lens group, an infrared detector 3 is arranged between the image processing module and the imaging lens group, The infrared detector detects the infrared signal within the visual angle range covered by the imaging lens group through the imaging lens group, and outputs the infrared signal to the image processing module, wherein the infrared detector is a long-wave working band (wavelength) of 8 to 14um Infrared detectors; such as figure 2 As shown, the imaging lens group includes a first lens 201, a second lens 202, a third lens 203, a fourth lens 204 and a fifth lens 205 from outside to inside, wherein the first ...

Embodiment 2

[0035] An infrared panoramic monitoring linkage system includes an infrared panoramic monitoring camera and an infrared following monitoring camera, a linkage controller controls the linkage between the infrared panoramic monitoring camera and the infrared following monitoring camera, and the infrared following monitoring camera is equipped with an infrared light emitter The active infrared camera, wherein, the infrared panoramic surveillance camera is the infrared panoramic surveillance camera described in Embodiment 1, is a passive infrared panoramic camera that does not have an infrared light emitter, and the content in Embodiment 1 should be regarded as The content of this embodiment will not be repeated in this embodiment. In the system, since the long-wave infrared detector is not suitable for receiving direct sunlight for a long time, the opening and closing of the shading cover is controlled by the linkage controller.

[0036] Wherein: the infrared follow-up monitoring ...

Embodiment 3

[0038] A monitoring method of an infrared panoramic monitoring linkage system is a monitoring method based on Embodiment 1 and Embodiment 2. Therefore, the content in Embodiment 1 and Embodiment 2 is applicable to this embodiment. The method includes setting an infrared panoramic monitoring camera and an infrared follow-up monitoring camera, the infrared panoramic monitoring camera is a passive infrared panoramic camera without an infrared light emitter, and the infrared follow-up monitoring camera is an active infrared infrared follow-up monitoring camera with an infrared light emitter Cameras, the more specific and repeated content will not be repeated in this embodiment. In the method, it is necessary to calibrate the linkage coordinates of the two cameras to form an associated model. The linkage coordinates of the two cameras are calibrated. After calibration, the monitoring In the process, the target is first captured by the infrared panoramic surveillance camera, and an o...

Abstract

The invention discloses a passive infrared and active infrared panoramic monitoring linkage system and method. The system comprises an infrared panoramic monitoring camera and an infrared follow-up monitoring camera; a linkage controller controls the linkage of the infrared panoramic monitoring camera and the infrared follow-up monitoring camera; the infrared follow-up monitoring camera is an active infrared camera provided with an infrared light emitter; the infrared panoramic monitoring camera captures a target; and after the target is captured, the infrared follow-up monitoring camera emits infrared light to the captured target according to target coordinates generated by the infrared panoramic monitoring camera, receives a reflected infrared light image, enlarges the infrared light image of the target and displays the enlarged infrared light image. With the passive infrared and active infrared panoramic monitoring linkage system and method of the invention adopted, 190-degree visual angels and horizontal 360-degree coverage can be realized, the defects of a traditional video monitoring system can be compensated, and the automatic degree of automatic identification, automatic alarm and the like of a security protection system can be improved.

Description

technical field [0001] The invention relates to a passive infrared and active infrared panoramic monitoring linkage system and method. Background technique [0002] At present, the viewing angle of the lens in the thermal imaging network camera used in the video surveillance industry is mostly within 90 degrees, and some equipment needs to add laser auxiliary equipment, so that the concealment of the equipment is greatly reduced. When monitoring, it is necessary to install multiple ordinary thermal imaging network cameras. Ordinary thermal imaging network cameras installed in this way are not conducive to installation and maintenance, and the imaging of ordinary thermal imaging network cameras has no overall sense and the picture is scattered. Moreover, the refraction thermal imaging panoramic camera is a passive non-contact detection and identification, which has good concealment and is not easy to be found. [0003] Compared with traditional thermal imaging, it can solve...
