TITLE Lightweight Object Detector for Pest Detection on Crops Under Field Conditions
ABSTRACT This paper outlines a light object recognition system that can be used to detect pests on crops under field scenarios in reality. The infestation of pests leads to low agricultural production and pests need to be identified at the right time in order to manage them. Nevertheless, current object detectors based on deep learning are usually computationally demanding and cannot be used with edge computing devices in smart agriculture. In order to overcome this shortcoming, a small and lean detector model is suggested that focuses on the low level of computation but high detection rate.A set of 2,000 images and 5,167 instances of pests of four types aphids, whiteflies, caterpillars, and beetles were evaluated using a compact and efficient detector model. The model proposed combines a lightweight backbone and depthwise separable convolution and feature pyramid boosting to enhance small pest detection. The experimental results show that the proposed detector has a precision of 91.6, a recall of 89.8 and a mean Average Precision ([email protected]) of 91.0. The model is highly efficient with only 6.8 million parameters, consumes 24 MB of storage, and the inference speed of 45 frames per second, which is significantly higher than those of conventional detectors like Faster R-CNN, and SSD in both speed and model size. The findings show that the suggested lightweight framework is efficient in harmonizing accuracy and computational power thus it can be used in real-time pest monitoring tasks. This method helps in early detection of pests, minimizing the amount of manual inspection as well as facilitating sustainable practices of precision agriculture.
