Construction monitoring method, device and system for cast-in-place deck type arch bridge in riverway

The invention particularly relates to a construction monitoring method, device and system for a cast-in-place deck type arch bridge in a riverway, and the method comprises the steps: firstly carrying out the first conversion of real-time field construction data based on a first construction data recognition model, and obtaining target field construction data; secondly, performing secondary conversion on the target field construction data based on a second construction data identification model to obtain reference field construction data, and then dynamically monitoring the target field construction data according to the real-time field construction data and the reference field construction data of the target field construction data. Because the real-time field construction data and the reference field construction data are field construction data with the same data format, the real-time field construction data can be compared with the reference field construction data, thereby judging the data accuracy of the
