Abstract

The invention relates to a method and a device for obtaining tri-dimensional and multi-spectral image simultaneously, which comprises an imaging optical system (1) and a focal plane component (2) which is arranged at the focus of the imaging optical system (1). The invention is characterized in that the focal plane component (2) comprises a light filter (201), a field diaphragm (202) and an area array CCD (203); the light filter (201), the field diaphragm (202) and the area array CCD (203) are arranged in sequence; the area array CCD (203) is connected with a digital data acquisition and processing system (3). The invention solves the technical problems of the complicated design and high price of the CCD chip of the area array CCD of a component. The invention has the advantages that the most important two parts in the system, which are a wide-angle optics and the area array CCD, can be easily bought in market, the specifications and models are many, the price is low, the development cycle is short, and the expense of the invention is lesser and the development cycle is shorter by comparing with the technical proposal of the specially developed CCD focal planes.

Description

technical field [0001] The invention relates to a method and equipment for simultaneously acquiring stereoscopic and multispectral images, in particular to a method and equipment for simultaneously acquiring stereoscopic and multispectral images applied in the field of space detection. Background technique [0002] For a long time, people have never stopped exploring the unknown world. With the continuous development of science and technology, especially the exploration of space is more frequent. The exploration of the space field mainly applies optical remote sensing technology, which collects light signals through an optical camera, and then remotely senses and transmits them to the ground to generate images. At present, most of the ground images generated by this optical camera are still in the stage of black and white images, and there are still a few solutions that can achieve stereoscopic and multispectral images. The key component of the CCD chip is the area array CCD...
