The invention discloses a ship black smoke automatic snapshot system suitable for a ship lock. The ship black smoke automatic snapshot system mainly comprises a camera system, a ship lock opposite-shore black and white grid chart, a ship body shielding recognition subsystem and a tail gas blackness grading subsystem. The camera system installed on one side of the ship lock is used for continuously shooting and recording the black-and-white grid chart installed on the side wall of the other side of the ship lock, and once a ship appears in a shooting picture, the situations that a ship body shields the black-and-white grid chart and tail gas changes the brightness of the black-and-white grid chart occur at the same time. According to the invention, the shielded part in the black-and-white grid chart is automatically identified by utilizing a hull shielding identification algorithm, the part of white grids with reduced brightness caused by black smoke are identified for the black-and-white grid chart of the unshielded part, and the black smoke grade of the tail gas is evaluated according to the brightness reduction degree. According to the invention, the purpose of automatically and accurately identifying the black smoke emitting ship by the ship lock is achieved.
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...
