The invention discloses an automatic capture system for ship black smoke suitable for a ship lock, which mainly includes a camera system, a black and white grid map opposite the ship lock, a ship hull occlusion identification subsystem, and an exhaust blackness grading subsystem. The invention utilizes the camera system installed on one side of the ship lock to continuously record the black and white grid image installed on the other side wall of the ship lock. Once a ship appears in the camera screen, the black and white grid image and the exhaust gas blocked by the ship body will appear at the same time. Change the brightness of the black and white grid map in both cases. The invention uses the hull occlusion recognition algorithm to automatically identify the occluded part of the black-and-white grid image, and for the black-and-white grid image of the unoccluded part, identify the part of the white grid whose brightness is reduced due to black smoke, and according to the brightness reduction The degree evaluates the level of exhaust black smoke. The invention realizes the purpose of automatic and accurate identification of black smoke emitting ships by ship locks.
Description
technical field [0001] The invention relates to the field of tail gas detection, in particular to an automatic capture system for ship black smoke suitable for ship locks. Background technique [0002] Under the background of the whole country's blue sky defense war, the main target of the water blue sky defense war is ship exhaust. Among them, the most intuitive and disgusting issue for residents of cities along the coast and rivers is the phenomenon of black smoke from ships. In 2018, Shanghai took the lead in China to require that "motor vehicles and boats must not emit visible black smoke." Later, cities such as Hangzhou and Qinhuangdao followed suit. Considering that the ship is sailing on open water and is a moving target, at present, maritime law enforcement officers mainly record video on their mobile phones, and carry a Ringelmann blackness color card to compare and judge the blackness of exhaust gas, which is highly subjective. question. For sea ships, the probl...
