The invention discloses a miniature multi-modal remote sensing imaging system, which consists of an image data acquisition part, an image data transmission part, a flight attitude control part and a data storage and control part, which can be flexibly arranged according to a space. The image data acquisition part consists of an image data acquisition device and a power supply device; the image data transmission part consists of four data transmission lines; the flight attitude control part consists of a set of MTI-G attitude control system; and the data storage and control part consists of an industrial control computer and a power supply device. The miniature multi-modal remote sensing imaging system has scientific conception and simple structure, overcomes the defect that the conventional large remote sensing system has high construction cost, large volume, heavy weight, low resolution ratio and poor timeliness, can be carried on an airplane, an airship, an unmanned plane or an unmanned airship to flexibly acquire high-resolution remote sensing data in real time, and has high practical value and application perspective in the fields of physical geography system technology and remote sensing.
Description
(1) Technical field [0001] The invention relates to a miniature multi-mode remote sensing imaging system in geography research, which is used in the field to acquire ground object image data in a large range on the ground, and belongs to the technical field of physical geography systems. (2) Background technology [0002] Remote sensing, as an effective means to obtain macroscopic, fast, real and objective information on the earth's surface, has been more and more widely used in various fields, and its importance has gradually been recognized. The current sensors can mainly be carried on two platforms, namely aerospace platform and aviation platform. Space platforms are mainly based on satellites, and the sensors on board have the following disadvantages: long development cycle, large-scale instruments, expensive construction, high operating costs, imaging is easily affected by air quality and meteorological conditions, and the ground resolution is relatively low. Low, can ...
