A Review of RGB Image-Based Internet of Things in Smart Agriculture

Agriculture is an important pillar of world development, and smart agriculture is an emerging paradigm in current practices. RGB Images contain rich information and play an increasingly important role in various scenes of smart agriculture. Image sensing, transmission, and other key aspects rely on agricultural Internet of Things (IoT) infrastructure. However, images contain substantial amounts of data, which poses new challenges to traditional IoT frameworks. In this article, using smart agriculture as the background, the research status of RGB image-based applications in agricultural IoT is reviewed from different perspectives. First, a new RGB image-based IoT framework based on cloud edge computing is proposed. The driving technologies of RGB image information collections, transmissions, and applications are summarized. Then, based on the previous research, an agricultural image IoT application case is presented. Finally, the challenges of RGB image-based agricultural IoT applications are discussed.
