A light field polarization imaging detection system for sea surface oil spill belongs to the technical field of photoelectronic imaging, and aims to solve a problem that the prior art is not suitable for real-time detection of sea surface dynamic scenes. The system is composed of a light field polarization information acquisition subsystem and an information processing subsystem; the light field polarization information acquisition subsystem comprises an optical filter, a front optical imaging main lens group, a micro-lens array and a micro-polaroid array imaging detector, and the optical filter, the front optical imaging main lens group, the micro-lens array and the micro-polaroid array imaging detector are coaxially arranged; the micro-lens array is located at the focal plane position of the front optical imaging main lens group, and the micro-polaroid array imaging unit is located at the focal plane position of the micro-lens array; the digital focusing function of the light field camera is utilized to realize snapshot imaging of sea surface oil spill on an airborne high-speed platform, and real-time high-precision acquisition of an oil spill image is realized; and polarization imaging can improve the contrast of oil spill images and improve the ability to distinguish different oil types.

Description

technical field [0001] The invention belongs to the technical field of photoelectric imaging, and in particular relates to a light field polarization imaging detection system for sea surface oil spills. Background technique [0002] In the process of oil development and transportation, due to factors such as natural factors or the failure of transport ships, oil spills on the sea surface frequently occur, which have a serious impact on the marine ecological environment. After an oil spill, it is necessary to know the location of the oil spill, the type of oil spilled, and the extent of its spread in order to designate appropriate countermeasures. [0003] Due to its advantages of miniaturization and convenience, airborne remote sensing technology is widely used in the field of remote sensing detection of sea surface targets. However, the background environment of the ocean is complex and particular, and there are problems such as complex sea surface illumination, poor contr...
