Problems solved by technology

However, when sunlight as a light source is affected by climate and time, resulting in changes in intensity and wavelength, the radiated light of the object to be illuminated will also change synchronously, resulting in a large deviation of the detection data, that is, the Remote sensing images will be affected by factors such as sensor calibration, solar azimuth, atmospheric conditions, etc. There are differences in the reflectance spectra o
