Power transmission network construction positioning method based on coordinate transformation

The invention belongs to the technical field of construction positioning methods, and particularly relates to a power transmission network construction positioning method based on coordinate transformation. Comprising the following steps: determining positioning points m and n based on an actual power transmission network construction range, and establishing a conversion coordinate system; determining a coordinate conversion proportion and a coordinate value conversion relation, determining a coordinate value relation of the positioning point in a second coordinate system, and determining a rotation angle and coordinate conversion of the to-be-positioned point; the method is used for rapidly measuring and positioning any point position in a construction range in any period of a construction stage, two positioning points need to be set in the early stage of construction planning survey, a new to-be-positioned point can be rapidly measured based on the two positioning points in the follow-up construction proces
