AI Technical Summary
Existing monocular vision monitoring methods are insufficient to meet the requirements for accurate reconstruction of the trajectory of overhead power transmission lines when faced with actual working conditions such as unknown camera installation locations and limited on-site calibration conditions. Furthermore, existing technologies and equipment are complex, costly, and have low safety.
The calibration is performed using a monocular camera, and the camera parameters are determined by the scale-adaptive BFGS convex optimization algorithm. Combined with Kalman filter tracking and image processing technology, the motion time history pixel coordinates of key points of the transmission line are obtained and a motion trajectory analysis report is generated. It is highly adaptable and flexible in calibration, and can achieve accurate reconstruction in complex field environments.
It enables accurate reconstruction of the movement trajectory of overhead transmission lines in complex field environments. The equipment is simple and inexpensive, avoiding the complexity of binocular or multi-camera systems, improving the reliability and security of the monitoring system, and is suitable for monitoring cameras in existing power grid systems.
