Description

technical field [0001] The invention belongs to the field of water color remote sensing spectrum measurement, in particular to an automatic device and method suitable for remote real-time monitoring of water surface spectrum. Background technique [0002] The measurement and analysis of optical characteristics of water bodies such as oceans and lakes is one of the foundations of water color remote sensing. For different water bodies, field tests to obtain a large number of measured spectra are essential for water color remote sensing modeling and authenticity testing of remote sensing products. For Type I water bodies in the ocean, the underwater profile measurement method is the preferred method, while for Type II water bodies with high chlorophyll and high suspended solid concentrations, such as ocean coasts and inland lakes, the measurement of apparent optical properties is relatively The suitable method is the measurement method above the water surface. Although NASA a...

[0002] The measurement and analysis of optical characteristics of water bodies such as oceans and lakes is one of the foundations of water color remote sensing. For different water bodies, field tests to obtain a large number of measured spectra are essential for water color remote sensing modeling and authenticity testing of remote sensing products. For Type I water bodies in the ocean, the underwater profile measurement method is the preferred method, while for Type II water bodies with high chlorophyll and high suspended solid concentrations, such as ocean coasts and inland lakes, the measurement of apparent optical properties is relatively The suitable method is the measurement method above the water surface. Although NASA and the International Water Color SIMBIOS organization have given relatively reasonable measurement methods and data processing schemes, in actual research, manual field sampling is used to obtain the apparent spectral data of the water body on site. There are still many problems. This type of monitoring method has a certain degree of accuracy, but the amount of data obtained by this type of measurement is small, the reliability is poor, and it is greatly affected by the site environment and human factors, and it is carried out at a point, so it is difficult to comprehensively It reflects the overall temporal and spatial changes of the ecological environment of the water body, and is time-consuming, laborious, and costly, and more importantly, real-time remote monitoring cannot be performed
