Imaging and remote sensing and monitoring device and method for pollution gas discharged by ship by differential absorption of filtering

Abstract

The device discloses an imaging and remote sensing and monitoring device for pollution gas discharged by a ship by differential absorption of filtering. The device comprises a theodolite, an imaging and remote sensing and monitoring unit mounted on the theodolite, a signal processing unit, a laser range finder and a camera. The imaging and remote sensing and monitoring unit comprises an imaging lens. The light passing through the imaging lens is divided into a reflected light and a transmitted light by a beam splitter. The reflected light is imaged by a first imaging detector after passing through a first molecular bubble and a first optical filter. The transmitted light is imaged by a second imaging detector after passing through a second molecular bubble and a second optical filter. Theinvention also discloses an imaging and remote sensing and monitoring method for pollution gas discharged by the ship by the differential absorption of the filtering. The imaging and remote sensing and monitoring device and the method for pollution gas discharged by the ship by the differential absorption of the filtering has the advantages of high monitoring accuracy, small data dispersion, strong anti-interference and inhibition ability, strong environmental adaptability, high monitoring sensitivity and good visibility of results.

Description

technical field [0001] The invention relates to the field of ship pollution gas discharge monitoring, in particular to a remote sensing monitoring device for differential absorption filter imaging of pollutant gas discharge from ships, and also to a remote sensing monitoring method for differential absorption filter imaging of pollutant gas discharge from ships. Background technique [0002] With the development of transportation technology and demand, the proportion of ship pollutant gas emission to air pollution is increasing day by day. However, ships are widely distributed and mobile, and the pollutant gas emitted is invisible and changes rapidly. , Working condition detection brings great difficulty, which is the technical bottleneck of the supervision system construction. [0003] Due to the difficulty in detecting the emission of pollutant gases from ships, the MARPOL Convention requires the use of oil product testing, that is, through the detection of pollutant conte...
