Precision Agriculture: Computer Vision-Enabled Sugarcane Plant Counting in the Tillering Phase

Abstract

The world’s most significant yield by production quantity is sugarcane. It is the primary source for sugar, ethanol, chipboards, paper, barrages, and confectionery. Many people are affiliated with sugarcane production and their products around the globe. The sugarcane industries make an agreement with farmers before the tillering phase of plants. Industries are keen on knowing the sugarcane field’s pre-harvest estimation for planning their production and purchases. The proposed research contribution is twofold: by publishing our newly developed dataset, we also present a methodology to estimate the number of sugarcane plants in the tillering phase. The dataset has been obtained from sugarcane fields in the fall season. In this work, a modified architecture of Faster R-CNN with feature extraction using VGG-16 with Inception-v3 modules and sigmoid threshold function has been proposed for the detection and classification of sugarcane plants. Significantly promising results with 82.10% accuracy have been obtained with the proposed architecture, showing the viability of the developed methodology.

Plant phenotyping relevance

サトウキビ個体数という植物形態・群落状態を画像から推定する手法を開発し、データセット公開と精度評価も行っており、表現型取得が研究の中心である。

Code and data availability

The authors publicly deposited their sugarcane tillering-phase video-derived image dataset and the annotated (bounding-box) dataset on Mendeley Data, both explicitly cited in the Data Availability Statement. No analysis code or trained model checkpoint is reported as available.
