Cross-shaped four-aperture field-of-view partially-overlapped bionic thermal imaging system

Abstract

The invention discloses a cross-shaped four-aperture view field partially-overlapped bionic thermal imaging system, and belongs to the technical field of photoelectric detection and image processing.The system comprises a detection imaging module, a system power supply board, an FPGA signal processing board and a PC processing display module. The detection imaging module comprises four single-aperture detection imaging sub-modules, and each single-aperture detection imaging sub-module comprises an optical lens, a detector and a detector driving circuit board. By means of a cross-shaped four-aperture field-of-view partially-overlapped bionic thermal imaging layout, a visual mode of high-resolution imaging in the center and large-view-field searching in the periphery similar to human eye vision is formed, the contradiction between the field of view and the resolution of a conventional thermal imaging system is relieved, bionic full-polarization thermal imaging or double-color thermal imaging is achieved through the cross-shaped four-aperture field-of-view partially-overlapped bionic thermal imaging system, the sensitivity of an optical system is improved, and the detection and recognition capacity of a moving target under the complex background is enhanced.

Description

technical field [0001] The invention relates to a bionic thermal imaging system with partial overlap of multi-aperture fields of view, in particular to a bionic thermal imaging system with partial overlap of "cross"-shaped four-aperture fields of view, which belongs to the technical field of photoelectric detection and image processing. Background technique [0002] Infrared thermal imaging is one of the key technologies in the development of weapons and equipment at home and abroad. It plays an important role in the development of weapons and equipment such as modern battlefield reconnaissance, observation and aiming, precision guidance, and detection of anti-intercept missiles. The infrared focal plane detector array (InfraRed Focal Plane Array, IRFPA) is much smaller than the silicon-based visible light CCD / CMOS detector, which makes it difficult for the infrared imaging system to meet the requirements of the imaging field of view while meeting the working distance.
