I. Introduction
Wheat yield, in terms of national food security and economic benefits, is an important cereal crop. And the number of wheat ears is an important parameter for estimating yield. Therefore, it is conducive to monitor wheat yield scientifically, quickly and accurately through the study of wheat ear counting. In addition, the study of spatial distribution differences of wheat ears in a given space, such as density, size, shape, texture and especially the number of wheat ears, can be the decision basis for precise management of wheat farmland.
