Problems solved by technology
However, due to the high cost of photosensitive detectors and the small size of the detectors, this type of sensor will require a large amount of deployment and control when used on the UAV platform, and the cost of the measurement field will be high, and the multi-camera design will also increase the weight and volume of the device. and cost
The multi-spectral remote sensing sensors of the above three methods are too complicated in structure, high in cost, and low in measurement efficiency, so it is difficult to apply to UAV airborne platforms

The invention belongs to the unmanned plane remote sensing technology field and especially relates to a narrow-band multispectral camera array imaging apparatus. The apparatus comprises a main imaging apparatus and several single channel imaging apparatuses arranged around the main imaging apparatus. The main imaging apparatus and the several single channel imaging apparatuses are fixed to and arranged on a bottom portion of an unmanned plane fuselage through cassettes. The main imaging apparatus comprises a first area array photosensitive sensor, a control unit and a memory cell. Each single channel imaging apparatus comprises a second area array photosensitive sensor, a control unit and a memory cell. The structure is simple. According to different unmanned-plane airborne platform conditions and observation orders, the number of the single channel imaging apparatuses is changed and manufacturing cost of an unmanned-plane airborne multispectral camera is greatly reduced. A common civil camera imaging sensor is used so that a ground control point quantity during multispectral measurement working can be decreased and field surveying work cost is reduced. Measurement efficiency is high and a problem existing in the prior art is solved.
Description
Technical field: [0001] The invention belongs to the field of unmanned aerial vehicle remote sensing technology, and in particular relates to a narrow-band multispectral camera array imaging device. Background technique: [0002] Multispectral resolution remote sensing is a remote sensing technology that uses more than two spectral channel sensors to simultaneously image ground objects. It divides the electromagnetic wave information reflected by objects into several spectral segments for receiving and recording, and can realize the simultaneous acquisition of target space information and spectral information. It is the main sensor for obtaining aerospace remote sensing data. At present, multi-spectral remote sensing sensors can be mainly divided into three types: filter type, multi-channel spectroscopic type and multi-camera type. The feature of the optical filter sensor is to change the filtering performance of the optical filter before the imaging system, tune the wavele...
