Currently, object detection based on deep learning has received extensive research and attention in the field of grid inspection, achieving high detection accuracy and recognition precision. However, pre-trained object detection models lack overall perception and reasoning capabilities, resulting in higher false positives and missings due to a lack of holistic understanding of challenging samples. Recently, the combination of natural language models and image understanding in multi-modal large language models has gained significant attention. In this paper, we propose the Grid-Blip model, a multi-modal large model enhanced with general knowledge, to specifically study wildfires detection in grid inspection. Grid-Blip is based on the blip model architecture, which includes a natural language model, a visual generation model, and a fusion model. We conduct large-scale sample annotation at the semantic level of whole-image grid inspection, providing crucial training samples for multi-modal large-scale model research. Furthermore, we investigate the design of the fusion model network, training the model to effectively integrate the pre-trained natural language model and visual generation model. Experimental results demonstrate that compared to object detection models, the proposed multi-modal large-scale model in this paper achieves overall semantic perception and reasoning capabilities. The Grid-Blip model reduces the false alarm rate for wildfire smoke trend prediction from 20% to 10% and the missed detection rate from 18% to 13%.
