Description

technical field [0001] The embodiment of the present invention relates to, but is not limited to, the non-destructive detection spectrum technology of agricultural product quality, especially a near-ground remote sensing jujube water content detection method and device. Background technique [0002] The domestic UAV low-altitude remote sensing platform is developing rapidly in the fields of agriculture, industrial marine mine resource exploration, rescue and other fields, and there is an urgent need for high-precision ground models to analyze remote sensing data. Remote sensing indices are widely used in feature mapping and parameter inversion of remote sensing images. Due to different remote sensing content and indicators, remote sensing index design and data collection conditions are different, there is no unified standard for establishing remote sensing data models. Most objects in nature have anisotropic reflection properties. Its reflectivity is closely related not on...
