Power transmission line windage yaw galloping monitoring method fusing cross laser and monocular vision

Abstract

The invention discloses a cross curve laser and monocular vision fused power transmission line windage yaw galloping monitoring method, and relates to the technical field of power system monitoring, and the method comprises the steps: carrying out the laser projection of a power transmission line through a cross curve laser, continuously collecting the laser contour of the line in a predetermined window through a monocular camera, and obtaining a contour image set; binarization processing and contour feature extraction are carried out on the contour image set, and line contour features are obtained through fusion; performing windage yaw galloping analysis based on the line contour features, and outputting windage yaw galloping data; and judging whether the wind deflection angle, the galloping amplitude, the vertical galloping amplitude, the horizontal galloping amplitude and the ellipse inclination angle meet dynamic monitoring thresholds or not, and if yes, performing line wind deflection galloping early warning. According to the invention, the technical problem of insufficient monitoring precision of the wind deviation galloping of the power transmission line in the prior art is solved, and the technical effect of improving the monitoring precision of the wind deviation galloping of the power transmission line is achieved.
