FIELD WHEAT STEM TILLERING NUMBER EXTRACTION METHOD

摘要

A field wheat stem tillering number extraction method, comprising: acquiring field wheat point clouds by means of a laser radar, and extracting any row of wheat point clouds in a research area (S102); projecting a Y axis to a plane, and retaining an X axis and a Z axis (S103); applying adaptive layering to obtain the number of clusters of the row of wheat (S104); applying hierarchical clustering analysis to obtain the tillering number of each cluster of wheat (S105); and further obtaining the stem tillering number of the whole row of wheat (S106), so that a field wheat stem tillering number is extracted. The feasibility of an algorithm is verified by comparing the wheat stem tillering number extracted by means of the method with an actually measured field stem tillering number, and the method realizes rapid, accurate and nondestructive extraction of a large-field crop stem tillering number, has higher universality, and provides the theoretical basis and technical support for the extraction of the field wheat stem tillering number.
