The invention discloses a bridge deformation monitoring system and method. The method comprises the steps that a plurality of deformation monitoring points are arranged on a bridge floor in advance; constructing a monitoring point video data set; filtering the monitoring point video data set; an execution step: determining a plurality of images required by detection from the data of the plurality of images; adjusting the plurality of images, and extracting sub-image data containing any deformation monitoring point; amplifying the sub-image data to a preset specification, extracting feature information of the sub-image data, and encoding the extracted feature information by using a self-attention module of an encoder; at the decoder, the coded feature information is input into an independent attention module; and taking the outputs of the plurality of sequential attention modules and the independent attention modules as the inputs of the two output heads based on the FFN, and generating a deformation monitorin
