Monitoring point data supplementing method and system based on tunnel surrounding rock transformation monitoring means

The present invention provides a monitoring point data supplementing method and system based on a tunnel surrounding rock transformation monitoring means. According to the method, on the premise of not destroying a tunnel, during arrangement of a total station prism at a tunnel site, a three-dimensional laser scanner is used for performing precise positioning on a coordinate point of the arrangedtotal station prism, and performing computer data processing on obtained scanned data, to obtain and store a data processing result, which is used for lookup when construction site total station prismdata is lost, so that a defect that the construction site total station prism data cannot be found after being lost is remedied, thereby ensuring normal construction. The system does not destroy a tunnel structure during a construction process, further can implement safe and fast measurement, and has good actual application value for assisting in tunnel establishment and ensuring measurement alignment stability. 本发明提供了一种基
