% ---------------- ABSTRACT ----------------
\begin{abstract}
Real-time variable choice of precision spraying operations in fields benefits from the constant acquisition of crop morphology. Costly LiDAR and ultrasonic radar can't maximize their high precision. They may slow down decision speed because the current spraying amount control needs to include more information about branches and leaves, which highly relies on the statistical features of regional morphology.

This study aims to develop a single-camera acquisition system and propose an algorithm based on Convolutional Neural Network (CNN) to identify different growth stages of cotton plants.
