Multi-charge coupled device group self-adaptive imaging method of cambered optical structure

Abstract

The invention relates to a multi-charge coupled device group self-adaptive imaging method of a cambered optical structure, belonging to a field of the image information acquisition and processing. By imitating an ommateum to adjust the nerve conduction mode with the change of the illumination under the condition of day alternates with night to obtain a self-adaptive imaging effect principle, the instrument uses a plurality of common charge coupled devices (CCD), corresponding auxiliary circuits and a neural processing algorithm to construct a biomimic self-adaptive adjustment imaging instrument. The imaging instrument has an imaging function of self adjusting fusion modes with the change of illumination conditions, can acquire a high-contrast image under a normal illumination condition, and also can acquire a high-brightness sensitive image under a weak illumination condition. The invention realizes high-definition surveillance and monitoring under the condition of day alternates with night, belonging to the image information acquisition and processing field.

Description

1. Technical field [0001] The multi-charge coupled device group self-adaptive imager and method of the curved surface optical structure of the present invention belong to the field of image information acquisition and processing. 2. Background technology [0002] In applications such as video scene monitoring and industrial production monitoring, image sensors are usually required not only to have high spatial resolution, but also to be able to obtain high-quality image information at night or in low light conditions. Ordinary image sensors are dependent on external lighting conditions, and the reduction of the brightness of natural light sources at night or in other special weather conditions will inevitably affect the imaging effect. Although an external artificial light source is usually used as an auxiliary light source for the image sensor at night, the brightness range of this light source is limited, and the placement of the light source will directly affect the imagi...
