Multi-camera staring detection system and imaging splicing method

Abstract

The invention discloses a multi-camera staring detection system and an imaging splicing method. The method is based on crossed seamless splicing of a large-area array detector and a large-view-field optical system, and an integrated design of two rows and two columns of four lenses is adopted, and seamless splicing of a plurality of area array detectors of any size can be achieved. The multi-camera staring detection system and the imaging splicing method have the advantages of simple splicing structure, seamless coverage, no optical vignetting and capability of realizing any n*n large-scale splicing. The splicing method can be applied to the fields of aerospace and the like, and is particularly suitable for an aerospace photoelectric detection system of the large-area array detector with the large visual field and wide coverage.

Description

technical field [0001] The present invention is a seamless splicing method for intersecting multiple area array detectors with a large field of view optical system, especially an integrated design of four lenses in two rows and two columns, which can realize any N×N area array detector seamlessly splicing method. Background technique [0002] With the continuous development of aviation and aerospace technology, the demand for photoelectric imaging systems with large area arrays is becoming more and more urgent. There are generally two ways to realize a large area array detector, that is, to directly prepare an area array detector of the required scale, or to use the method of area array splicing. [0003] Ultra-large-scale area array detectors are costly and technically difficult, and further increasing the scale of area array detectors has technical difficulties and risks in device yield.

Problems solved by technology

[0004] Chinese invention patent CN101650423B’s optical splicing of large area array optoelectronic devices can only realize the splicing of area array detectors in 2×3 or 2×2 mode, the prism structure and splicing are complex, and there is optical vignetting at the splicing seam; splicing requires complex mechanical structures For fixing and installation, the volume and weight are relatively large, so it cannot be used in lightweight design

[0005] Chinese invention patent CN 102928903A realizes the seamless optical splicing of large area array photoelectric devices in 3×3 mode area array detector splicing, which requires mirrors and multiple turns, and the detection area cannot be covered simultaneously
