Description

technical field [0001] The invention relates to a multispectral camera for marine oil spill monitoring and an imaging processing method, belonging to the technical field of marine oil spill monitoring, and in particular to a drone-borne multispectral camera for marine oil spill monitoring. Background technique [0002] After a marine oil spill accident, it is very important to be able to respond quickly, identify the oil spill on the water surface in time, and draw the spatial and thickness distribution of the spilled oil, which is very important for determining the oil spill recovery plan, modeling the floating trajectory of the oil spill, and evaluating the treatment effect of the dispersant. role. With the advancement of aerial optical remote sensing technology, airborne optical imaging has greatly promoted the efficiency of oil spill emergency response, especially the multispectral camera, which can simultaneously obtain image information of multiple spectral bands on th...

Problems solved by technology

Due to the inconsistent imaging time of each spectral segment, the time-sharing imaging multispectral camera has very high requirements on the stability of the airborne platform, and requires precise image registration. The post-image processing is very difficult, and the spectral switching components are large in size, making it difficult to realize small and PTZ installation

Although the multi-spectral camera based on the camera array can realize multi-channel simultaneous imaging of the camera, it is difficult to synchronize the control of the multi-camera, and the multi-camera array is too large to be used on the micro UAV platform.
