The invention provides a power transmission line stretching field arrangement method based on oblique photography data, which combines a three-dimensional lightweight platform, three-dimensional GIS geographic information data and oblique photography data as underlying data of site selection to simulate a real scene, and selects a proper position to arrange a stretching field according to a site selection specification on the basis, so that the construction efficiency is improved. According to the position of the stretching field, stretching field arrangement data are automatically calculated and output, arrangement construction of the power transmission line stretching field is assisted, the method is adopted for line stretching field site selection, the global site position selection can be observed comprehensively, and the site position is reasonably selected; automatic calculation of key data such as span, elevation and rotation angle is supported, and manpower and material resource cost is greatly saved.
