The invention discloses an air, ground and water three-dimensional environmental
pollution sensing device and a data fusion method. The device mainly comprises a double-rotor unit, a walking unit, a positioning navigation unit, a
pollutant monitoring unit, a
buoyancy control unit and a host unit. The double-rotor unit is responsible for air flight and
underwater sneaking of the device; the walking unit is responsible for land movement of the device; the positioning navigation unit is responsible for the moving direction of the device in water, land and air; the
pollutant monitoring unit is responsible for monitoring environmental
pollutant parameters around the device; the
buoyancy control unit is responsible for adjusting the
underwater diving depth of the device; and the host unit is responsible for regulating and controlling all the functional units and carrying out data fusion
processing to generate a pollutant evaluation report. According to the efficient fusion
processing method based on the multi-source heterogeneous data, all-around space-
time perception and fusion
processing of different pollutant concentration data in air, ground and water environments are achieved, and the method is an ideal choice for continuously improving global
ecological environment quality.
