The invention provides a standardized line data acquisition method. The method comprises: presetting the categories of to-be-shot photos of a power transmission line tower according to a PMS; selecting the power transmission line tower manually or automatically; according to the selected power transmission line tower and the photo categories, shooting the photos, generating a file in a specified format by the previewed photos meeting the requirements, and storing the file into a first folder; performing image processing on the generated file in the specified format and storing the processed file into a second folder; and exporting the stored file, performing statistic analysis on the exported file, and making statistics on acquired images and to-be-acquired images. The method is used for quickly acquiring tower information and superposing the acquired tower information with tower longitude and latitude information and shooting time, thereby facilitating later management and maintenance.
