Steel sheet pile U-shaped groove soil body falling risk early warning method based on target detection

The invention provides a steel sheet pile U-shaped groove soil body falling risk early warning method based on target detection. The method comprises the steps that S1, picture data collection, manual marking and training data making are carried out; s2, taking the target detection network as a basic framework, training the target detection network by using the training data collected in the step S1, and improving the precision of a target detection network model by adjusting and optimizing training parameters so as to meet the accuracy requirement of the model; s3, identifying whether a soil body exists between the steel sheet piles or not by utilizing the target detection model established in the step S2; and S4, determining the actual position of the soil block in the foundation pit and giving early warning information by establishing a mapping relation between the pixel size of the object in the image and the actual size. By constructing the target detection network, whether the soil body exists in the La
