Fast and lightweight automatic lithology recognition based on efficient vision transformer network

Traditional methods of lithological classification often rely on the expertise of appraisers and the use of sophisticated measuring instruments. These methods are susceptible to staff experience and are time-consuming. To overcome these limitations, researchers have explored the use of rock images and intelligent algorithms to automatically identify rocks. However, models developed for automatic rock properties identification often require high-performance equipment that cannot be readily deployed on lightweight edge devices. To address this problem, we significantly extend our previous research and propose a method for automatic rock properties identification called SBR-EfficientViT. The method is based on an efficient vision converter and builds on our previous training framework. We also developed a training and application flow framework for the method, which can run with memory requirements of less than 720 MB and graphics memory of 1.6 GB.
