The invention discloses a method for three-dimensional line scanning measurement based on industrial robot guidance. An adapter part connected to a robot end of a three-dimensional line scan sensor isdesigned and the adapter is provided with a translation, rotation or fan scanning structure and a position encoder, and the encoder can be synchronized by an external trigger signal; the a three-dimensional line scan sensor is installed at the end of the robot through the adapter part; after the robot is controlled by the program and the end of the robot moves to a scan position, the three-dimensional line scan sensor completes three-dimensional scanning measurement of a measured object based on rotation, translation or fan scanning of the adapter part controlled independently; and when scanning data are collected, synchronous acquisition of the real-time positions of the three-dimensional line scanning sensor and the adapter part is realized through a synchronization signal. According tothe invention, robot guid
