Embodiment Construction

[0021] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] The infrared-visible dual-spectrum target source proposed in this embodiment has a structure such as figure 1 shown. Wherein, the target source includes a rear shell 1, an infrared heating element 2, a bakelite 3 with uniform heat conduction, a frosted glass 4, a supporting collar 5, a ceramic heating plate 6, a light emitting diode 7 and a wire hole 8.

[0023] Both the rear shell 1 and the infrared heating element 2 are made of toughened polyethylene. The rear shell 1 and the infrared heating element 2 are connected to form a closed shell. The ceramic heating sheet 6, the frosted glass 4 and the uniform heat conductor 3 are all located inside the closed casing. The ceramic heating chip 6 is abutted and fixe...

Abstract

The invention belongs to the field of infrared visible light bi-spectrum optical detection, and specifically relates to an infrared visible light bi-spectrum concentric target source which can be detected by a mid-long wave infrared detector and a visible light detector and of which the imaging temperature and brightness can be regulated and controlled. The infrared visible light bi-spectrum target source comprises an infrared heat-generating body and a light emitting diode, wherein the infrared heat-generating body and the light emitting diode are concentrically installed, so that the infrared radiation generated by the infrared heat-generating body is consistent to the center of the visible light source generated by the light emitting diode. The target source can provide a registering point for simultaneous imaging by infrared and visible light imagers, and the imaging size of the registering point on the infrared and the visible light imagers can be dynamically adjusted. The center position of the image of the registering point on the infrared and the visible light imagers can be easily extracted, and the extracted central position has accurate matching performance. The adaptability of registering point to extraction environment is improved, and the extraction efficiency and registering precision of registering point pairs are increased.

Description

technical field [0001] The invention belongs to the field of infrared and visible light dual-spectrum optical detection, and in particular relates to a temperature- and brightness-adjustable infrared-visible dual-spectrum concentric target source that can be simultaneously imaged by a medium-long wave infrared detector and a visible light detector. Background technique [0002] Infrared and visible light dual-spectrum image fusion technology can enhance scene understanding and highlight targets by making full use of the complementary information of infrared and visible light two-spectrum images. fields have a wide range of applications. In the application of infrared and visible light image fusion technology, the infrared imager and the visible light imager image the same scene, but due to the differences in the installation positions of the infrared imager and the visible light imager and the parameters of the detector itself, the obtained infrared and visible light images ...
