When establishing the prediction model,the conventional foundation deformation and settlement prediction method ignores the randomness of the observation data series,weak generalization ability of the model and poor prediction results,a gray linear prediction method for foundation settlement and deformation of high-rise buildings based on UAV mapping technolo-gy is proposed.The UAV surveying and mapping technology is used to collect the foundation image data,register and correct the offset image.On this basis,a gray prediction model is established.Through the accumulation of data,the inherent law of the data is strengthened,the randomness of the observation data column is weakened,the model convergence speed is accelerated,and the foundation settlement deformation prediction is achieved through the settlement deformation numerical fitting curve.The prediction accuracy of the proposed method is verified by a high-rise building project.The results show that the proposed meth-od has a high prediction accuracy.
