Abstract

The invention provides a spectral reflectivity detection method and system. The spectral reflectivity detection system comprises an ambient light sensing module, a target spectrum acquisition module and a data processing module. The ambient light sensing module collects a detection ambient light spectrum at a target detection moment and sends the detection ambient light spectrum to the data processing module; the target spectrum acquisition module acquires a detection target spectrum at the target detection moment and sends the detection target spectrum to the data processing module; the data processing module determines the detection ambient light spectrum and the detection target spectrum corresponding to the same target wavelength, and determines a detection reference spectrum based on the detection ambient light spectrum and determined mapping parameters, and the detection reference spectrum is the spectrum of the second ambient light; the spectral reflectivity of a to-be-detected object is determined based on the detection target spectrum and the detection reference spectrum; and the mapping parameters represent the mapping relation between the reference spectrum and the ambient light spectrum. According to the technical scheme, the spectral reflectivity of the to-be-detected object can be accurately calculated.

Description

technical field [0001] The present application relates to the technical field of optical processing, and in particular to a spectral reflectance detection method and system. Background technique [0002] Hyperspectral imaging refers to the combination of imaging technology and hyperspectral technology to obtain the two-dimensional geometric space and one-dimensional spectral information of the object to be measured, and obtain continuous and narrow-band image data with high spectral resolution. [0003] Hyperspectral technology is a technology that uses a narrow and continuous spectral channel (different from three channels such as RGB (Red Green Blue, red green blue)) to obtain spectral information of the object to be measured, and can collect multiple spectral channels of the object to be measured The electromagnetic wave data (that is, spectral information), and obtain the interesting information of the object to be measured according to the characteristics of these data,...
