Visual transmission tunnel deformation monitoring method, device and equipment and storage medium

The invention provides a tunnel deformation monitoring method and device based on visual transmission, equipment and a storage medium, and relates to the technical field of tunnel deformation monitoring. The method comprises the steps that an n-1 first monitoring point is monitored through an nth machine vision instrument, the absolute offset of the nth machine vision instrument is obtained according to the pre-stored absolute offset of the n-1 first monitoring point, n is a positive integer larger than one, and the first machine vision instrument is used for monitoring a first datum point to obtain the absolute offset of the first machine vision instrument; monitoring the nth first monitoring point through the nth machine vision instrument, and obtaining the absolute offset of the nth first monitoring point according to the absolute offset of the nth machine vision instrument; and obtaining the deformation of the tunnel according to the absolute offset of each first monitoring point. According to the method
