Background
The current crop pest detection method is mainly realized through image classification and a target detection algorithm on a cloud server, and generally, a universal model has huge parameter quantity, consumes a lot of computing resources and has larger power consumption. This is because there are generally no power consumption and computational limitations in the server in order to adapt to the wider models and algorithms. In fact, under the specific scene of fungus disease and pest detection, the number of model parameters is small, tasks are not complex, and large-scale calculation is not needed. Therefore, low power consumption and low cost are currently the best choice for portable and deployable devices.
It is well known in the art to reduce the parameter calculation through matrix factorization, such as where a layer of normal convolution is factorized into depth convolution and point-by-point convolution. In addition, the memory consumption can be reduced by quantizing the model parameters and the input data. Fixed point quantization of fp32 to int8 is typically employed.
