Abstract
A method and a device for crop canopy chlorophyll fluorescence three-dimensional distribution information acquisition are provided. The device includes a Cropobserver canopy chlorophyll fluorescence detection device, a 3D camera and a computer system. The 3D camera is connected to the computer system, Visual studio 2017 and MATLAB 2018 are run in the computer system, and the Visual studio 2017 calls a point cloud library and a computer vision library to realize three-dimensional visualization of chlorophyll fluorescence information of crops to be tested. By means of the new method and the new device, the problem of incompleteness of the two-dimensional chlorophyll fluorescence information distribution acquired is solved, overall 3D visual distribution of crop canopy chlorophyll fluorescence distribution is realized, and important technical support is provided for acquisition and research of three-dimensional visual distribution information of chlorophyll fluorescence of the whole crop canopy.
