Abstract

The invention discloses a YOLO-SITCOL-based automatic target detection and spatial location method of a fixed station. The method comprises the following steps: configuring acquisition hardware of thefixed station; acquiring an image; based on a YOLO algorithm, realizing automatic target detection on a geographic object; based on an SITCOL algorithm, realizing reverse calculation on a geographicpixel frame by virtue of an image pixel frame; and fitting the best position point by virtue of multiple spatial positions of a single object. The method disclosed by the invention effectively reducesworkload of manually viewing a target, improves inspection efficiency, reduces consumption of manpower and financial resources and has a better application value in practical application.

Description

technical field [0001] The invention belongs to the technical field of digital close-range photogrammetry, and in particular relates to a fixed-station automatic target detection and space positioning method based on YOLO-SITCOL. Background technique [0002] During inspection and supervision, manual target viewing is usually required, and the inspection efficiency is low. The fixed base station measurement system uses the communication tower as the data acquisition platform, and installs high-precision binocular cameras, camera space position acquisition equipment GPS antennas, camera space attitude acquisition equipment electronic PTZ, based on GPS / electronic PTZ combined positioning and attitude sensor, the tower base measurement system has the ability of Direct Georeferencing (DG). [0003] Combining the theory and engineering application of the fixed base station mapping system can reduce the consumption of manpower and financial resources, and has good application valu...
