Supermarket fruit recognition mainly relies on manual processes, and computer vision has emerged as a solution. However, challenges remain, including low accuracy for some fruits, difficulties in deploying them on terminal devices, and handling misidentified images. Therefore, this paper researches mobile fruit recognition based on deep learning, aiming to replace manual identification. First, the paper constructs the DailyFruit-49 dataset, which includes images of 49 types of fruits. Addressing the challenges of recognizing fruits with high feature similarity, packaging obstructions, and small shapes, as well as the deployment issues on low-compute devices, the backbone model meeting deployment requirements was selected. A new attention module, RMA, was designed, and the ViT Block was improved to enhance the model’s detail recognition and deep semantic feature integration capabilities, resulting in the Dense RMA_ViT model. The loss function was also improved based on Focal Loss. Ablation experiments on the public dataset Fruits-262 verified the effectiveness of these improvements. Finally, a fruit recognition system was implemented on actual devices to meet practical usage needs. The system collects misidentified fruit images based on user interactions and automatically fine-tunes the model’s weights based on these images. Over time, as the system collects more images, the model’s recognition accuracy and generalization ability improve, effectively handling misidentified fruits in real-world applications. %K 水果识别， %K 数据集构建， %K 改进注意力机制， %K ViT， %K 系统设计， %K 模型权重自更新
