Special Issue Information
Dear Colleagues,
The growth of the world's population puts enormous pressure on traditional agriculture to meet the growing demand for food and fiber production while minimizing the environmental impact. As a result, the agricultural sector continues to explore innovative technological solutions to improve agricultural practices. One such solution is the integration of intelligent technologies, including next-generation sensors, communications, autonomous flight systems, artificial intelligence, robotics, and analytics.
This Special Issue is dedicated to investigating the research and development of solid-state sensors to collect varied agricultural data. The aim is to monitor biochemical parameters, such as nutrition, humidity, temperature, light, and pH in real time, and biochemical interactions, such as predation, parasitism, and competition. Sensors are used at different spatial and time scales to provide farmers with data-driven insights into crop and livestock growth and health, pests, pesticides, soil health, water, fruit quality, greenhouse gases, and volatile compounds. This Special Issue will also cover the utilization of low-power sensors, energy harvesting technologies, and high-throughput phenotyping using sensors.
We welcome original research, opinions, and reviews covering various specialized crops, including vegetable, ornamental, and field crops and seeds from other managed ecosystems. With this Special Issue, we aim to provide valuable insight into the latest advancements in agricultural technology that can improve the sustainability and efficiency of agricultural practices.

Abstract: Sugarcane is an important economic crop. After machine harvesting, the impurity rate of sug-arcane is an important metric, which affects the sugar output rate. In order to obtain the impurity rate and detect primary impurities, this paper proposes an impurity rate estimation method for post-harvest sugarcane based on rotated bounding box and binocular vision. Firstly, the sugarcane mixture image including sugarcane segments, sugarcane tips, and sugarcane leaves was captured by a binocular camera. Secondly, the YOLOv5-obb algorithm is used to obtain rotated bounding boxes for sugarcane mixture. Next, based on binocular vision, the actual dimensions of sugarcane segments are calculated. And the sugarcane segments are fitted as cylinders, enabling the calcu-lation of their volume and mass. Finally, the impurity rate of post-harvest sugarcane is calculated based on the mass of sugarcane segments and the total mass of the mixture. Experimental results demonstrate that rotated bounding boxes can fit the shape of each target accurately, with a mean average precision (mAP) of 93.5%. The model also performs well in detecting occluded and overlapped targets. The average detection time per image is 0.02 s, and the average time for impurity rate estimation per image is 0.19 s. For 830 test images, the average mass error of sug-arcane segments is 10.88%, the total mass error is 2.58%, and the total impurity rate error is 10.16%.
