The invention discloses a trenchless calandria three-dimensional track optimization measurement method based on a positioning induction device. The method includes the following steps: 1) before pipeline paving, installing a positioning inductor at a front end of each MPP tubular material part; 2) after pipeline paving, transmitting a signal through a remote controlling inductor; 3) by means of a hand-holding positioner, obtaining a three-dimensional coordinate of the end of each MPP tubular material part; and 4) calculating the three-dimensional track of all pipelines according to the coordinates and performing charting. By means of the method, quick measurement and positioning to a trenchless calandria can be carried out at any time without damage on pavement or entrance into the calandria, so that the method has great practical significance on protection, external force damage prevention and quick positioning and utilization to the trenchless calandria. Compared with a conventional method, the method is high in measurement precision, is free of influences, such as mis-positioning and the like, due to depths of different pipelines, is simple in operation, allows the situation of a present pipeline to be observable through the hand-holding positioner, and is suitable for accurate positioning of underground pipelines in large range.
