Lens light splitting mode-based focal plane splicing aerial surveying camera with extra large plane

Abstract

The invention relates to a lens light splitting mode-based focal plane splicing aerial surveying camera with an extra large plane, wherein the camera comprises a panchromatic camera module and a color camera module. The panchromatic camera module includes two groups of lenses; and a lens light splitting mode is employed to realize simultaneous imaging of four groups of focal plane assemblies. The two groups of lens share one shutter assembly to ensure synchronous exposure of a plurality of cameras; the four focal plane assemblies share nine CCD devices with the size of 10K*10K to form an array with the size of 3*3; and the total pixel is 30K*30K. Besides, the color camera module includes an RGB true color camera and a CIR color infrared camera; and an Mosaic filtering sheet and a Bayer interpolation mode are used to realize the color imaging; and an obtained color image is fused into a panchromatic image with a high resolution ratio by an interpolation mode, thereby obtaining a color image with the high resolution ratio. In addition, the pixels of the panchromatic camera and the color camera are 10K*10K. According to the invention, problems of small span and low resolution ratio of the existing digital aerial surveying camera can be effectively solved; and the provided camera can meet a carrying requirement of a general aerial surveying plane platform.

Description

technical field [0001] The invention belongs to the technical field of aerial remote sensing photogrammetry, and in particular relates to an inter-mirror spectroscopic focal plane splicing super large area array aerial survey camera. Background technique [0002] Aerial remote sensing is mainly used in surveying and mapping to survey and map topographic maps, make orthophoto maps and compile various thematic maps after professional interpretation, repair and edit topographic maps and maps, update GIS databases, make digital maps, and master land resources. Use the current situation and predict the development trend. At the same time, aerial remote sensing imaging has a wide range of applications in agricultural and forestry remote sensing, resource surveys, environmental monitoring, disaster assessment and other fields. [0003] Different from reconnaissance cameras, aerial survey cameras have high requirements for image geometric accuracy and relatively low resolution requ...
