Abstract

The invention provides a telescopic imaging device and an imaging method. The device comprises a telescopic imaging optical assembly, a sub-view-field electric scanning module and an image splicing and fusing module. The sub-view-field electric scanning module is used for dividing a complete view field to be imaged into a plurality of sub-view-fields consistent with the view field range of the telescopic imaging optical assembly and scanning one by one; the sub-view-field electric scanning module comprises multiple stages of stacked electric scanning unit devices and is used for realizing sequential scanning of multiple sub-view-fields based on multi-stage directional deflection of light beams; the telescopic imaging optical assembly is used for sensing each sub-view-field to generate sub-view-field images; and the image splicing and fusing module is used for collecting pictures generated by the telescopic imaging optical assembly for the view fields of all angles and splicing and fusing the images into a synthesized image. According to the invention, on the basis of forming a telescopic image with a large-angle view field, the high resolution of the synthesized image is ensured, so the problem that a telescopic imaging system in the prior art cannot give consideration to both the large-angle view field and the high resolution is solved.

Description

technical field

[0001] The present invention relates to the technical field of telescopic imaging, in particular to a telescopic imaging device and method. Background technique

[0002] The telephoto imaging system in the prior art mainly realizes the expansion of the imaging field of view through the traditional zoom lens. The zoom lens is expensive and bulky, and the imaging resolution is limited by the number of pixels of the CCD image sensor array, so it is difficult to expand. For an image sensor with the same size and resolution, the larger the angle of the imaging field of view will lead to insufficient resolution of the output film, and on the basis of ensuring the image resolution, it cannot meet the demand for a larger imaging field of view. Therefore, it is difficult to simultaneously realize the expansion of imaging field of view and the improvement of image resolution in existing telephoto imaging systems. Contents of the invention
