A spliced ​​large area array digital aerial survey camera

Abstract

The invention discloses a spliced large area array digital aerial camera, which comprises a full color camera module and a multispectral camera module, wherein the full color camera module comprises a full color camera objective lens, a reflective pyramid beam splitting prism and four full color charge coupled devices (CCDs); and the multispectral camera module comprises four multispectral objective lenses and a CCD; the full color camera objective lens is positioned in the middle, and the four multispectral objective lenses and the CCD are symmetrically arranged at the periphery of the full color camera objective lens; the rear of the full color camera objective lens is provided with the reflective pyramid beam splitting prism; and the periphery of the reflective pyramid beam splitting prism is provided with the four full color CCDs. By the camera, the problem that a digital aerial camera has small breadth is solved, and a 20k*20k large-breadth high-resolution aerial image is provided; the camera comprises wide-angle, middle-angle and normal-angle full color camera objective lenses and multispectral objective lenses; and during work, the full color camera objective lenses at different angles can be flexibly selected according to different mapping applications, the angles of the multispectral objective lenses are matched with those of the full color camera objective lenses, and the problem that the conventional area array digital aerial camera has small field of view and single objective lens type is solved. Meanwhile, due to a mode of splicing a single full color objective lens and multiple full color CCDs, the image splicing difference caused by exposure difference of various full color cameras in the mode of splicing the multispectral objective lenses and the multiple CCDs is avoided.

Description

technical field [0001] The invention relates to an aerial surveying and mapping camera, in particular to a spliced ​​large area array digital aerial surveying camera. Background technique [0002] Area array digital aerial survey cameras are widely used in dynamic monitoring of land resources, forestry resources survey, vegetation coverage survey, land classification, land use (current status) monitoring, etc. The survey results are applied to land and resources data update, environmental monitoring, cultivated land protection, planning and land law enforcement inspection, land use management and checking the reliability of statistical data in various places, so as to provide real and reliable information support and basis for legal administration of land management. The main tasks of the high-resolution area array digital aerial camera in the aerial remote sensing system are as follows: (1) provide basic geometric image data support for the application research of other rem...
