Problems solved by technology

[0004] Wherein, the water body apparent spectral measurement device includes a ground feature spectrometer with a single spectral channel and a three-channel spectral measurement system with three spectral channels; however, the ground feature spectrometer in the related art is only equipped with one spectrometer, When using the ground object spectrometer to measure, the operator manually measures the spectral data in three directions, and performs multiple rounds of measurements at different times; however, the operation of the ground object spectrometer is complicated, and the time-sharing measurement leads to measurement The error is large, and the measurement results of each round need to be manually labeled and recorded, resulting in the inability to process the measured spectral data online and realize unattended real-time monitoring

[0005] In addition, although the three-channel spectral measurement system in the related art can simultaneously measure spectral data in three directions, the three spectral channels are realized by three spectrometers, each of which is a spectral channel; This spectrometer not only makes the optical path structure of the three-channel spectral measurement system complex and expensive, but also needs to manually record the spectral data measured by each spectral channel with corresponding labels during the measurement operation, resulting in the measured spectral data. Online processing, unable to realize unattended real-time monitoring
